Dmos reacted to c.frio for an article, Apple’s OS X will soon cease to exist
You’ve known it as Mac OS X or OS X for years, but that’s about to change in 2016. Apple will replace OS X with “MacOS” or “macOS,” which would be more in line with its software naming scheme. iOS, macOS, watchOS and tvOS rolls off the tongue a lot easier than having “OS X” inserted anywhere in that enumeration.
In a support document related to its early WWDC announcement on Wednesday, Apple let the “macOS” name slip for the second time, MacRumors reports. The new name was spotted in documentation detailing the new revenue split for subscription-based apps, as seen in the following screenshot.
Apple quickly fixed the error, replacing “macOS” with OS X. But at this point it seems pretty clear that a name change is due. Earlier this year, Apple used the new macOS name in an environmental website update. At the time, the company quickly changed its “MacOS” reference – with a capital M – to OS X after it was discovered.
Dmos reacted to c.frio for an article, The MacOS Sierra Compatibility List
If the Mac is fairly new it will certainly support macOS Sierra, but many older Macs are getting cut off from the compatibility list, including any Mac made before late 2009. That means many Macs that support the current versions of Mac OS X system software won’t be able to run MacOS Sierra at all, and instead will be stuck staying on an earlier software release.
List of Macs Compatible with MacOS Sierra 10.12
According to Apple, the official compatible hardware list of Macs capable of running Mac OS Sierra 10.12 is as follows:
MacBook Pro (2010 and later) MacBook Air (2010 and later) Mac Mini (2010 and later) Mac Pro (2010 and later) MacBook (Late 2009 and later) iMac (Late 2009 and later) This list of supported Macs is offered directly from Apple, shown during the MacOS Sierra debut presentation at WWDC 2016 conference. The still from that presentation is shown below with the same compatibility list:
How to Check Your Mac for MacOS Sierra Compatibility
The simplest way to determine if your Mac is compatible with MacOS Sierra is to check the model make and model year, here is how to do that:
Open the Apple menu in the upper left corner and choose “About This Mac” From the “Overview” tab, look under the current system software version and for the computer model and year
If the Mac is the same or a later model year than what is shown in the macOS Sierra compatibility list above, the Mac is compatible with 10.12.
You may notice the compatibility list for MacOS Sierra 10.12 is a little curious because some of the Macs that are incompatible have better hardware than some of the hardware that is included in the compatible list. It’s unclear why this is, but this does suggest that support for MacOS Sierra is not just a matter of hardware specs alone, as the minimum system requirements for macOS Sierra are not clearly defined by minimum CPU type or speed, RAM, GPU, or disk capacity. That makes macOS Sierra a little unusual compared to some of the other Mac OS X releases from years past, but as time goes on we may get a clearer picture as to why this is.
Developers can download MacOS Sierra right now from the App Store and developer center, whereas the general public will have to wait until the fall to get their hands on the final version.
Of course it’s not just MacOS that is getting an update this fall, and for mobile users, you can check the iOS 10 compatibility list of supported iPhone and iPad models too.
Dmos reacted to c.frio for an article, What we learned about SSDs in 2015
Despite their wide use, SSDs are a young technology, one we're still learning about. Here's a roundup of the best research on SSDs in 2015.
Researchers at Facebook and Carnegie Mellon?checked out both reliability and performance of SSDs. They found that high temps can cause SSDs to throttle back on performance. Slow server? Check SSD temp.
From?researchers at SanDisk?we learned that the log-structured I/O management built into SSDs is seriously sub-optimal for databases and apps that use log-structured I/O as well - which today is most of them.
But the?most startling SSD paper?came out of Korea, where researchers concluded:
As the paper shows, using an SSD poorly can waste most of its possible performance. And until vendors give users the right controls - for example, pausing garbage collection - SSDs will inevitably fail to reach their full potential.
Finally, the unpredictable latency of SSD-based arrays - often called all-flash arrays - is gaining mind share. The problem: if there are too many writes for an SSD to keep up with, reads have to wait for writes to complete - which can be many milliseconds. Reads taking as long as writes? That's not the performance customers think they are buying.?
The Facebook paper offered the best data on SSD reliability. Key findings:?
System write activity correlated with SSD failure, probably because flash writes require a lot of power.? SSD unrecoverable read errors are relatively common: 4.2 to 34.1 percent of the SSDs reported uncorrectable errors.? SSDs are sensitive to temperature - more so than hard drives. REPLACING FLASH?
Today's SSDs run on NAND flash, which is far from the ideal storage medium. Clunky addressing. Very slow writes. Poor endurance. And it's an analog medium, driving vendors to 3D architectures.
? Reinventing Analytics, Sideways The traditional way of doing analytics with lots of separate, silo products for each aspect of analysis is going away. New platforms allow new "sideways" combinations of features. Sponsored by SAP? ? But it's cheap, thanks to widespread consumer use, so engineers have made it work in much more demanding applications. But better alternatives are on the way:
3D Xpoint.?Intel and Micron's hastily announced?3D Xpoint?and?Optane drives?are promised for 2016, but I'll believe it when I see it. It is supposed to combine the performance, density, power, non-volatility and cost advantages of all available memory technologies on the market today. The technology is up to 1,000 times faster and has up to 1,000 times greater endurance than NAND, and is 10 times denser than conventional memory.
But as details have continued to trickle out, the future of 3D Xpoint looks less certain. Incompatibilities with current tech, pricing concerns, single sourcing and more are clouding the picture.?
Nantero.?The company hopes to be the ARM of memory technology, licensing to all comers. Their?carbon nanotube memory?offers promises like those of 3D Xpoint:?
Fast as DRAM - with much lower power consumption? Unlimited endurance? Non-volatility - >1000 years at 85C? Picosecond switching smaller feature sizes than flash - down to 5nm I?wrote about Adesto?last November, so they aren't 2015 news, but they are another NVM technology that could surprise us one day the way flash did 10 years ago.
THE STORAGE BITS TAKE
SSDs have always been a transitional or bridge technology. There's no way that we'd be using SSDs today if we'd had flash technology in 1957 instead of IBM's RAMAC.
But billions of open SATA ports made for a ready market. And now that the early fears of low endurance have passed, we're ready to move on. NVMe, 3D, TLC and all-flash/no SSD arrays will drive the market in 2016.
Since CPUs aren't getting faster, making storage faster is a big help. We can expect more of that in 2016, along with much lower flash prices.
Dmos reacted to c.frio for an article, Fixing Wi-Fi Issues in OS X El Capitan
For most Mac users who are experiencing issues with wi-fi connections in OS X El Capitan, simply ditching old preference files, followed by creating a new network location with custom DNS settings and an MTU change is enough to resolve whatever wi-fi problems they may have had. This is a multi-step process but not particularly difficult.
You?re going to be deleting a few system level preference files and creating a new network location. Before getting started, you should start and complete a backup of the Mac with Time Machine. Don?t skip backups. Trash Existing Wi-Fi Preferences in OS X to Start Fresh
Create a new folder on your Desktop called ?wifi prefs backup? or something obvious
Turn off Wi-Fi from the menu item in the upper right corner of OS X
Go to the Finder (the smiley face icon in the Dock), and hit Command+Shift+G to bring up the Go To Folder command, choose the following path exactly:
Hit return to go to that folder, then locate and select the following files:
Move all of these files into the folder you created in step 1 on the desktop (you can also delete them if you?re confident and have made a backup)
Reboot the Mac
Turn on Wi-Fi from the wireless network menu again in the upper right corner of OS X
If your wi-fi works now, great, but for most users, you?re not quite finished yet! Now you need to create a new custom network location. Create a New Wi-Fi Network Location with Custom DNS
Quit any open apps that are using wi-fi or networking (Chrome, Safari, Mail, etc)
Go to the ? Apple menu and select ?System Preferences?
Choose the ?Network? control panel, then choose Wi-Fi from the list on the left side
Click the ?Location? menu and select ?Edit Locations?, then click the [+] plus button to create a new location, giving the new location an easily identifiable name like ?Fixing My WiFi? and click ?Done? to add it
Next to ?Network Name? join the wi-fi network and authenticate with the router password as usual
Next, select the ?Advanced? button in the lower corner of Network preferences, then go to the ?TCP/ IP? tab, choose ?Renew DHCP Lease?
Next go to the ?DNS? tab, and on the left side ?DNS Servers? list, click the [+] plus button to add a new DNS server* ? I use 126.96.36.199 and 188.8.131.52 for Google DNS but you can choose whatever you want
Next, choose the ?Hardware? tab, then next to ?Configure? choose ?Manually?
Change ?MTU? to ?Custom? and set the MTU number to 1453, then click on ?OK?
Finally, choose the ?Apply? button to set your network changes
* If you?re not sure what DNS to use, you can find the fastest DNS servers for your situation with a benchmarking utility. Typically the fastest servers are Google DNS and OpenDNS, but results may vary per region.
Now wireless connectivity should be working flawlessly in OS X, and back at full speed. Try things out by navigating around the web, doing a speed test, and just using the internet as usual.
The solution outlined above almost always works to resolve wireless networking issues in OS X, particularly if they occur after updating to a new version of system software or a point release. Additional Wi-Fi Troubleshooting Tips
If you?re still having trouble with wi-fi in OS X 10.11 or later, try the following:
Reboot the Mac in the Safe Mode, then reboot again (this dumps caches)
Reboot the Wi-Fi router the Mac connects to
Update the Wi-Fi router firmware if an update is available
Join a 2.4 GHz network N network rather than a 5 GHz G network or B network
Reset the Mac SMC
Extreme: try to clean install OS X El Capitan
Extreme: if all else fails, downgrade from OS X EL Capitan to the prior version of OS X on the same Mac with Time Machine
Have you had wi-fi issues or speed problems with OS X El Capitan? Did this work to resolve them for you? Let us know in the comments, or if you had another solution, let us know that too!

The roadmaps published by FanlessTech show specifications for Intel's 15-watt Skylake-U series, a low-power product targeting thin-and-light notebooks and ultralights.
As noted by the publication, Intel is apparently streamlining its product offering to one Core i7, one Core i5, one Core i3, one Pentium, and two Celerons, not including two vPro chips. It's not yet clear which SKU Apple will choose for its MacBook Air update, but likely candidates include chips from the Core i5-6200U and Core i7-6500U series.
Both versions feature integrated Intel HD 520 graphics, with the Core i5 chips clocked at 2.3GHz and 2.4GHz, while Core i7 models jump to 2.5GHz and 2.6GHz.
Aside from clock speed bumps, Intel's new 14-nanometer architecture is expected to improve battery life by up to 30 percent while also boosting CPU performance by 10 to 20 percent over the company's current line of Broadwell chips. The enhancement will likely have a pronounced effect on thin-and-light systems like the Air.
While Intel's roadmap lacks specific launch dates, previous rumors suggest Skylake CPUs could start shipping in October.
Dmos reacted to c.frio for an article, OS X Yosemite and trim support: What is it and should you use it?
Let me point out right off the top that if you're using a Mac with built-in SSD storage, none of this applies to you. Trim support in 10.10.4 is only relevant to Macs with upgraded third-party SSD. And even then, trim may only be relevant to a subset of those Macs.
"Trimming" is a technique used by operating systems to do "garbage collection" on an solid state disk. Trimming enables the SSD to consolidate blocks of flash memory to make sure performance remains high. Without garbage collection, an SSD can slow down over time as more data is written to the drive.
If you bought your Mac with an SSD factory-installed by Apple, you don't have to worry. First party SSDs do their own garbage collection, so no changes are necessary for those systems. Third-party SSDs equipped with SandForce controllers, like the ones sold by Other World Computing (OWC), don't need any help, either.
With Mavericks and previous OS X releases, some Mac users who had upgraded their computers with third-party SSDs used Trim Enabler and other tools to get trim support to work on their drives. That went away with the release of Yosemite, which enforced a new security measure called "kext signing." Kernel extensions, or kexts, are system drivers. Kext signing makes sure system drivers stay unaltered to prevent potential security problems. Unfortunately, this meant that utilities which altered the way SSD drivers work stopped working on Yosemite.
While kext signing is still Yosemite's law of the land, 10.10.4 introduces a new "trimforce" command that enables trim on SSDs. OS X 10.10.4's new "trimforce" command is entered through the Terminal:
sudo trimforce enable
The operating system barks back a long and potentially scary message about how using trimforce may cause "unintended data loss or data corruption" before turning it on.
The problem is that not all SSDs implement trim support the same way, and some models from some manufacturers appear to have very buggy trim implementations all together.
So why did Apple enable this? Well, it looks like this is an early implementation of something we expected in El Capitan, but many newer third-party SSDs don't have any trouble with trim support and will benefit from it, so it's a net positive.
Again, if you're using a Mac equipped with a factory-installed SSD or one that uses an SSD that has a SandForce controller, this doesn't apply. If you're using a third-party SSD, use this command at your own risk. I'd strongly recommend checking with user support forums and any other online resources for your SSD maker before enabling trimforce on your Mac, and whatever you do, back up early and often.

Here?s what you?ll need to do to download Quartz Debug and monitor FPS in OS X:
Go to Apple Developer Downloadsand search for ?Graphic Tools? ? download the version appropriate for your version of OS X or Xcode (no, you do not need the entire Xcode app to download Graphics Tools)
On the mounted Graphic Tools disk image, open the app called ?Quartz Debug? (drag it into your /Applications/ folder if you?ll use it often)
Pull down the ?Window? menu item and choose ?FrameMeter? to show the live FPS and CPU monitor
When the FrameMeter shows up place it somewhere appropriate for your usage and start interacting with OS X or an application to immediately see how the FPS and CPU gauge changes live, showing you the frame rate of onscreen activity.
This brief video below demonstrates how to use Quartz Debug for a live FPS display:
You?ll notice the FrameMeter looks like a little dashboard tachometer of sorts, displaying FPS and CPU usage simultaneously. With FrameMeter enabled, just interact with OS X or an application and you can see how frame rate and processor usage is impacted. Even something as simple as resizing a window or scrolling through a Finder window with OS X Yosemite transparencies is notable, and similarly, you?ll find that using something like Increase Contrast, which disables the transparent effects as well as making interface elements more defined, has a side effect of boosting FPS and reducing CPU load during those type of tasks.
As a developer tool, this is mostly intended for performance testing of applications, but it can still be an interesting way to benchmark some aspects of OS X, or at least see how certain activity may or may not impact the visual performance on a Mac. It can also offer a way to directly see the performance boosts offered by tricks like these to speed up OS X Yosemite, particularly on older hardware.
Quartz Debug is an interesting utility, you can use it to enable Retina HiDPI mode on old Macsthat don?t even support a Retina display (which, some time ago, this was one of the big hints that Retina displays were coming to the Mac), though it?s basically unusable so don?t be fooled into thinking you?ll suddenly have a better display experience. The entire Graphics Tools suite is actually pretty fun to have around on a Mac if you?re the tinkering type, Quartz Composer in particular is good fun to play around with, as it allows you to make or edit fancy animations and screen savers like this one in OS X.

Apple introduced an additional layer of security for iPhone, iPad and Mac users a few years ago by rolling out two-step verification for Apple IDaccounts. Two-step verification prevents anyone from accessing an Apple ID account, even if they know the password, by requiring a four-digit verification code sent via SMS or Find My iPhone. When you enable two-step verification, you must register at least one trusted device capable of receiving SMS text messages.
Once activated, two-step authentication is required when managing your Apple ID through My Apple ID, signing into iCloud, or making iTunes, iBooks or App Store purchases from a new device. Apple has also expanded two-step authentication to iMessage and FaceTime, requiring users to input an authentication code from a verified device on accounts that have two-factor verification enabled to prevent unauthorized entry attempts through both services.
Steps to Enable Two-Step Verification
Sign into My Apple ID by clicking Manage your Apple ID.
Click on Password and Security > Get Started? > Continue >Continue > Get Started.
Set up at least one trusted device by clicking on Add a phone number?, entering your four-digit verification code and clickingVerify.
Click on Continue. Write down and/or print your Recovery Key and click on Continue.
Enter your Recovery Key and click on Confirm.
Click on the checkbox if you agree to the conditions and click onEnable two-step Verification.
To ensure continued access to your Apple ID account after enabling two-step verification, it is essential that you record your recovery key in a safe place. Losing your two-factor recovery key could permanently lock you out of your Apple ID account, especially in the event you are being hacked. Without the recovery key, you will be forced to create a new Apple ID.
Two-step verification may provide an additional layer of security, but it is still highly recommended that you set a secure password for your Apple ID account. Avoid using common names, phrases or dictionary words in your password, and try to use as many lowercase and uppercase letters, numbers and symbols as possible.
Dmos reacted to c.frio for an article, iWork for iCloud Beta Apps Now Accessible Without an Apple Device
Apple on Thursday made Pages, Numbers and Keynote accessible to users without an Apple device through iCloud Beta. Starting last night, anyone can sign up for an Apple ID to access the trio of iWork for iCloud beta apps for free. Each account comes with 1GB of complimentary iCloud storage for use with the productivity software.
While the offer is currently limited to the iCloud Beta website, it is likely that Apple will rollout the feature to the regular version in the future. To create a free Apple ID account, navigate to iCloud Beta and click on the get started link in the top banner to begin the signup process.
Apple introduced iWork for iCloud at WWDC 2013, bringing Pages, Numbers and Keynote to the web. After receiving "overwhelming response," Apple eventually opened the service to all users a few months later. iWork for iCloud has been steadily improved since then with interactive charts, an updated design, expanded language support and more.

TextEdit is a surprisingly handy Mac app that is mostly underutilized and under appreciated, and while it?s certainly not going to compete with the abilities of pro text editors like BBEdit and TextWrangler, it can function as a simple code editor in a pinch. One of the quintessential features of any good text editor is the ability to jump to a specific line number, and TextEdit can do that.
To jump to any specific line in TextEdit,have a document open and then hit Command + L to bring up the ?Select Line? tool. Then you just need to enter the line number and hit Return to move directly to and select that specified line of text in the active text document.
There is one small problem here, which you may have noticed already? TextEdit doesn?t display line numbers, and there is no option to show them.
This obviously makes it a bit cumbersome to jump around to line numbers since you?d be relying on memory, another app, or someone else telling you what line number to see or edit, which realistically means you should be using a professional text editing app. Perhaps it?s not too surprising to have a Select Line tool in TextEdit, but it is a little weird to be missing the line number display given the inclusion of the line jump feature. (On a side note, you can manually hard code line numbers to a document, but that would never be a good idea for something like source code).
For best results with this, you?ll probably want to have set TextEdit to be Plain Text by default, kind of like Notepad from the Windows world, otherwise TextEdit opens a file as Rich Text which can lead to irregularities.
Realistically, if you?re doing anything complex that either requires line numbers or is aided by them, you should really just download TextWrangler, which is free and quite good and yes it displays line numbers, or go with BBEdit, which is paid and for the pros. Either way, it will make your life easier.
Dmos reacted to c.frio for an article, Fixing Bluetooth Discovery Problems in OS X Yosemite
Some Mac users running OS X Yosemite have discovered Bluetooth to become unreliable, either dropping device connections constantly or even simply not discovering a working Bluetooth device. For example, some users who are trying to use a PS3 controller with the Mac in OS X Yosemite may find that the Mac is unable to locate the Bluetooth controller at all, despite being right next to the computer and properly following the configuration instructions.
An easy way to know if this is a Yosemite-specific issue for you is if the Bluetooth device worked fine prior to updating to OS X Yosemite, and the Bluetooth preference panel shows nothing despite there being various devices readily available in the area:
While general Bluetooth disconnection issues can be caused by a variety of things, from low battery to poor signal quality, this particular instance where Bluetooth hardware is outright not detected appears to be specific to OS X Yosemite and Bluetooth, and the resolution is somewhat unusual, but also fairly easy:
Disconnect all USB devices from the Mac (anything connected to a USB port, unplug it)
Shut down the Mac and leave it turned off for 2 minutes
Boot the Mac again as usual, then reconnect all of the USB devices again
Try again to sync the Bluetooth device(s) with the Mac through the System Preference panel of OS X
I know those troubleshooting directions sound a little bizarre, but those are actually Apple recommendations for fixing the Bluetooth discovery problem with OS X Yosemite, and it almost always works!
If you?re still running into Bluetooth problems after trying the weird USB disconnection two minute protocol, resetting the Mac SMC may help as well as simply turning Bluetooth OFF and back ON again through the OS X preference panel.
Presumably the Yosemite and Bluetooth problem will be resolved in an upcoming OS X 10.10 system update, so be sure to update OS X when new versions become available.
