    OsxDaily Reports: Siri has the ability to read anything on the screen of an iPhone or iPad to you. And yes, that means Siri will quite literally read aloud whatever is open and on the display of an iOS device, whether it’s a web page, an article, an email, a text message, anything on the screen will be read out loud by Siri, and you’ll even have controls for speeding up and slowing down speech, as well as pausing and skipping sections
    To get the excellent Siri Speak Screen ability working on your iPad or iPhone, you will need to enable a little appreciated accessibility feature called speak screen, and then it’s just a matter of initiating the proper request with Siri.
    How to Have Siri Read Screen Text to You on iPhone, iPad
    First we’ll enable the Speak Screen feature and then use Siri to access it in iOS, here’s how it works:

    Open the ‘Settings’ app and go to ‘General’ and then to “Accessibility” Go to “Speech” and flip the switch for “Speak Screen” to the ON position Exit Settings Now from just about any screen in iOS, whether settings, a webpage, messages, email, summon Siri and say “Speak Screen” to have Siri read the screen and all screen contents to you Use the onscreen controls to stop reading or adjust the reading speed, section, or stop (or ask Siri to stop reading) For a practical example of how this can work, let’s imagine you have found a great article on the web and you’d like it read to you aloud. All you need to do is load up the web page in Safari (or another browser of iOS) and then summon Siri and say “Speak Screen” and Siri will start reading the text of the article to you. 
    Using the onscreen controls you can skip slow down Siri speech, skip backwards to a section to have it re-read, pause the speech, skip forward a section you don’t want read, or speed up the Siri voice reading. 
    This trick pairs really well with either the iPad or iPhone if you have the volume turned up enough to hear the reading out of the built-in speakers, but it also works wonderfully with headphones or speakers. Using this trick you could have Siri read you an article, an email, a web page, anything on screen, while you commute, or are out and about, or even just laying around.
    You can even use this trick with the Hey Siri voice activation feature, making it one of the better accessibility features available in iOS.

    Teaser Paragraph:
    Rarely, the Mac App Store may report erroneous app download statuses or even offer a malformed file leading to an app that doesn’t launch or is partially downloaded. These situations are almost always the result of an interrupted or corrupted download, but can occur in some other scenarios as well.
    Sometimes simply deleting the app in question can resolve any surrounding difficultly, but on some occasions that isn’t possible or isn’t effective. These type of unusual errors can typically be resolved by manually clearing out the Mac App Store cache, and then re-downloading the app, or re-visiting the Mac App Store. This tutorial will walk through completing that process.
    Accessing the Mac App Store Temporary Download Caches
    Be sure to backup your Mac before beginning this process, it’s unlikely something will go wrong if you follow the instructions but because you are editing a system level cache directory it’s always good practice to backup and be sure your data is safe. Don’t skip backing up. 
    open $TMPDIR../C/com.apple.appstore/

    Quit out of the Mac App Store Open the Terminal, found in /Applications/Utilities/ and type the following command exactly: Hit Return and the com.apple.applestore folder will open in the Finder of Mac OS Move the contents of this folder onto the desktop of the Mac (or if you are confident, move the contained temporary data into the Trash) Importantly, do not delete or adjust any other files outside of this directory, when finished close the com.apple.applestore folder Relaunch Mac App Store Now you should be able to download or re-download the apps or Mac OS installer files again, and they should work properly as intended.
    This process can help if you’re unable to download something from the Mac App Store, if it’s showing up erroneously as downloaded when it’s not, or if there are constant verification errors or other problems with the downloaded app or installer file. For example, you may need to do this if you notice that the Mac App Store is persistently showing a Mac OS installer as “Downloaded” despite not having completed the download as discussed in this Sierra troubleshooting detail. If you delete the temp cache data, it will allow you to re-download that Mac OS installer again in such a situation. 
    This troubleshooting trick will not resolve user level cache issues with the App Store, which are typically superficial behavior like the App Store not loading pages or behaving in an inordinately slow manner. 
    For those wondering about alternatives that do not involve the command line, you can also approach this temp cache directory through the Mac App Store “Debug” menu, but the latest versions of Mac OS and Mac App Store do not seem to support the current defaults write command to reveal the option. If you happen to know an updated defaults string that works with modern Mac OS releases, be sure to leave a comment.

    Teaser Paragraph:

    A feature added in macOS Sierra is handy for those who frequently switch among two languages while typing.

    Twitter buddy Michael Fessler alerted Mac 911 to a great help for those who frequently type in keyboards for two different character sets, like Latin and Hebrew, Chinese, Arabic, and many others. You can make a quick-switch option from the keyboard without resorting to a menu, by turning a tap of the Caps Lock key into a keyboard swap.
    The option appears in the Keyboard system preference pane in the Input Sources tab. It has a lot of explanation: “Use the Caps Lock key to switch to and from U.S. Press and hold to enable typing in all uppercase.”
      This won’t appear when you have two keyboards that use the same basic underlying set of characters. That may be confusing, because, for instance, you can add a French keyboard that uses a different layout, like AZERTY, and it’s not an option. Both the U.S. and French keyboards derive characters from the same Latin set.
    Pick a non-Latin keyboard, and the option appears. If you have multiple non-Latin keyboards, the first one you added is the only one that Caps Lock swaps between. If you add more and then delete the first or more, the most recently added or the last one remaining becomes the swappable keyboard.

    The Keyboard preference pane now lets you set a simpler way to swap for certain keyboards.
    This doesn’t work for all non-U.S. layouts, however. If you add Japanese, as my friend Matthew Amster-Burton did, the checkbox doesn’t appear. That’s because macOS’s default input method for Japanese is Hiragana, which relies on the underlying roman syllables, according to Matthew.
    You can seemingly predict this: if the keyboard preview in the preference pane shows Latin (or “Western”) characters, the keyboard option doesn’t appear; if the preview shows non-Latin characters, it does.

    Teaser Paragraph:
    Now that macOS Sierra has Siri built directly into the Mac operating system, you’re probably wondering what exactly you can do with the handy virtual assistant on your computer.
    It turns out that Siri has many abilities unique to the Mac, which you can’t perform on an iPhone or iPad with the virtual assistant. Of course nearly all of the traditional Siri commands from iOS work in macOS as well, which is just one of many reasons we think Siri is one of the features in macOS Sierra that you’ll use most. 
    Accessing Siri on the Mac
    Before issuing commands to Siri, you’ll want to summon the virtual assistant. The easiest way to do this are by clicking on the menu bar item in the upper right corner, the Dock icon, or by hitting the Option + Spacebar keystroke. 

    When you click to activate Siri, Siri will stick around until you either click the icon again or close the Siri window in the corner of the display. 
    Now that yo just a taste of the type of commands Siri can perform on the Mac. You can substitute obvious things as well, for example you can ask about different settings or preference panels, Wi-Fi instead of Bluetooth, any application the Mac, ask to show any file type or document name, and so much more. 
    Mac Siri Commands List
    This list will give you an idea of what to try and where to start with Siri on the Mac:
    Put my computer to sleep Activate the screen saver Make the screen brighter Make the screen dimmer  Is Bluetooth on? Turn Bluetooth off / on Lower the volume Increase the volume Show me privacy settings Show me location settings Show me network settings What is my desktop wallpaper I forgot my iTunes Password How fast is my Mac?  How much memory does my Mac have? How much free disk storage is available? What is my Mac serial number? What OS version is this?  How much iCloud storage do I have? Open Mail application  Open Safari Open Messages  Open the website for OSXDaily.com Open the webpage (site name or site URL) Send a message to (name) saying (message) Open the Documents folder  Open the Pictures folder  Show me files named “screen shot” Show me files from yesterday Show me image files from last week Show me documents from two days ago Show me what I was working on yesterday Show me my music Play (song name) in iTunes What song is playing? Skip this song Remind me to call (name) in 20 minutes Show me pictures from last October Show me my photos from Hawaii Your best bet to mastering Siri on the Mac is to simply play around with the virtual assistant, asking various questions, changing command language, asking for different types of documents or apps, requesting different information, just have fun. 
    In fact, nearly every one of the commands from this Siri commands list work on the Mac as well, though obviously iPhone and iPad specific tasks and features are not possible on the Mac, though some will adjust accordingly. Explore and have fun.
    The Siri Commands List, Courtesy of Siri on the Mac
    Another option is to ask Siri directly, what can you do for me? This works to reveal many additional command options as well, since Siri for Mac has a little help guide that comes along for the ride, you can access the details by opening Siri and pressing the info ? question mark button, or if you ask Siri on the Mac what the assistant can do for you. This shows a variety of menu items showing different types of commands to ask Siri, some of which are Mac specific and others which are generalized for Siri. 
    Those menus from the Mac showing giant lists of Siri commands have been posted below for easy browsing, check out the screen captures and try them out yourself:

    With MacOS Sierra now available, Mac users can now get Siri on their computers, have improved iCloud integration, unlock their Macs with an Apple Watch, use Apple Pay on the web, and much more. Before you go diving right into updating to macOS 10.12 though, you should take a few precautionary steps to prepare for the software update.
    We’ll walk through some simple steps to prepare for updating to macOS Sierra so that you can install the new Mac OS system software with ease. 
    1: Check Hardware for Support 
    Is your Mac supported by macOS Sierra? If it’s relatively new and built in the middle of 2010 onward, the answer is probably yes, but you’ll want to be sure by viewing the macOS Sierra compatibility list first.
    Most apps that are compatible with El Capitan are compatible with Sierra as well, just be sure you update your apps after you install macOS Sierra. If you have any mission critical apps, you may want to reach out to the developer to investigate if a particular application has any issues or not.
    2: Backup, Backup, Backup
    No matter what system software you update, you always should backup first. Don’t skip making a complete and thorough backup of your Mac before installing MacOS Sierra.
    Setting up Time Machine on a Mac is easy and allows for simple backups and restoring in the odd event something goes haywire. 
    Don’t skip a backup, it’s important. 
    3: Installing macOS Sierra
    Did you backup? Did you insure your Mac is compatible? And you backed up the Mac completely so that all of your data is secure? Don’t skip the backup. Then you’re ready to update and install macOS Sierra. The simplest way to update is by letting the installer run after downloading, this will bring the current version of Mac OS X up to date to the Sierra, it’s a pretty easy process:
    Go ahead and download macOS Sierra now from the Mac App Store When the Installer launches, go through the simple steps and select your Mac hard drive to update to macOS Sierra macOS Sierra will download and install, rebooting the Mac when completed Typically a macOS Sierra installation takes a bit over an hour, but it can vary depending on computer speed, what version is being updated, and how much stuff is on the Mac.
    When it’s finished installing, the Mac will reboot itself into macOS 10.12 Sierra, ready to go and enjoy.
    Additional macOS Sierra Installation Notes
    If you were in the macOS Sierra beta testing program, you might want to opt out of Mac OS X beta software updates after you get to the final version, otherwise you’ll keep getting minor beta releases offered as updates If you need to re-download macOS Sierra, delete any existing beta installers on the Mac, reboot, and you should be able to get the latest macOS Sierra installer Want to make a bootable installer drive? You can create a macOS Sierra boot drive easily with these instructions, you’ll need an 8GB or larger USB drive and the original installer handy, that’s about it Users can perform a clean install of MacOS Sierra if desired as well, we’ll cover that in the future If you’re skittish about updating, waiting until the first minor point release version (in this case, macOS Sierra 10.12.1) is a relatively common conservative strategy to try and avoid any potential bugs that may linger in the final release As long as you made a backup beforehand, you can downgrade from Sierra if need be after the fact If you want to use the iOS-to-Mac and vice versa clipboard feature, you’ll need to be sure the iPhone or iPad is updated to iOS 10 or later Are you prepared for Sierra?

    Teaser Paragraph:
    Ever wished you could make a dialog alert pop-up on the Mac by way of the Terminal? Well it turns out that you can with the always useful osascript command, which allows execution of AppleScript from the Terminal. For those who spend a lot of time at the command line of MacOS, this can be a great little trick to notify you of when a specific task has completed, or even to be included as part of a script. This is sort of a visual approach to one of my favorite simple Terminal tricks which is to verbally announce when a command line task has completed.
    Let’s review how advanced Mac users can trigger alert dialog boxes in the MacOS GUI from the command line. You can choose to specify a specification application to trigger the pop-up alert to appear within, or, perhaps better yet, trigger a alert dialog in whatever the foremost application in Mac OS X is.

    And yes this works in every version of macOS or Mac OS X that has existed, so there shouldn’t be any compatibility issues here.
    How to Make a Dialog Alert Pop-Up in Mac OS
    Perhaps the most useful dialog alert is one that is visible from anywhere and is thus sent to whatever is the foremost application. This insures the alert box isn’t missed.
    The syntax to trigger a dialog alert box in the frontmost application on the Mac is as follows:
    osascript -e 'tell application (path to frontmost application as text) to display dialog "Hello from osxdaily.com" buttons {"OK"} with icon stop'
    The resulting pop-up alert box looks like this:

    For example, you could use this to trigger a dialog box in the frontmost application when a task at the command line has completed. Let’s say we’re running a python script and want an alert box to notify us when it has completed, the syntax for such a use case could look like the following:
    python MagicScript.py && osascript -e 'tell application (path to frontmost application as text) to display dialog "The script has completed" buttons {"OK"} with icon caution'
    That example would trigger a dialog box that says “The script has completed” with the yellow caution icon to the frontmost application in Mac OS X GUI after python has finished running ‘MagicScript.py’. You can pick other icons like stop, note, caution, or even specify a path to a custom icon if desired.
    While you can specify an application, System Events, or SystemUIServer, choosing the broader frontmost application allows the alert dialog window to appear onscreen no matter what application is at the forefront. Let’s cover triggering dialog alerts into specific apps, since that may be desirable as well. 
    Trigger a Dialog Alert in Specific Application
    To send a dialog or alert into a specific application, simply specify the app name in question, like so:
    Triggering an alert dialog in Mac OS Finder by way of command line:
    osascript -e 'tell app "Finder" to display dialog "Hello from osxdaily.com"'
    Triggering an alert dialog in Terminal app via command line:
    osascript -e 'tell app "Terminal" to display dialog "Hello from osxdaily.com"'
    Triggering an alert dialog in Safari via command line:
    osascript -e 'tell app "Safari" to display dialog "Hello from osxdaily.com"'
    Trigger an alert dialog to System Events by way of command line:
    osascript -e 'tell app "System Events" to display dialog "Howdy Doo"'
    You can specify any application to send the alert to this way, but for many of us the broader frontmost or System Events are likely the more useful choice.
    If a general pop-up dialog trigger is too intrusive, you might appreciate sending alerts to the Notification Center on Mac with terminal-notifier, terminal-notifier is a third party solution that allows command line messages to appear in the general Notifications Center of Mac OS. An even less invasive option would be to trigger a notification badge onto the Terminal Dock icon though that may be too subtle for many users needs.
    Anyway, this is a basic overview of triggering visual alert dialogs into the graphical interface of Mac OS by way of the command line. You can go much deeper than this if desired through more complex uses of AppleScript and osascript including having interactions with the dialog box impact what happens next, but that’s approaching a more complex topic which would be better served in it’s own article. Users who are interested in learning more about scripting with AppleScript can review the documentation included with the Script Editor app which is quite thorough and detailed.
    Have any interesting ways to use this tip, or know of another method to trigger dialog boxes into the GUI of Mac OS from the command line? Let us know in the comments.
