OsxDaily Reports : Many languages use accents and diacritic marks to change how a letter or vowel sounds. Accordingly, you may find it useful to know how to type accents and diacritical marks on a Mac using the keyboard. This should be particularly useful for users who also type or write in Spanish, Portuguese, French, and Greek, but obviously this applies to many other latin language scripts as well.
Modern versions of Mac OS offer an exceptionally fast way to type letter accents, and it’s quite easy to use.
For typing most accents on Mac you will use either a sustained keypress, or you can use the option / alt key and another modifier key to get the accent or diacritic on the desired letter. Generally speaking you either press and hold the letter to accent, or press and hold the modifier keys, and then you release those keys and then type the letter to be accented. That may sound a little confusing but if you give it a try yourself you’ll see how it works, it’s quite easy once you get the hang of it.
How to Type Accented Characters on Mac the Fast Way
New versions of Mac OS allow users to easily type accented letters and diacritical marks by using a sustained keypress on a single key. For example, if you press and hold on “e” a pop-up will appear after holding that key for a few moments which displays which accents are available for that particular letter or character.
Press and hold on the letter you wish to accent, continue holding the letter until a menu with character accents are displayed
Choose the character accent with the mouse, or press the number corresponding below the accent in the menu
You can leave the accent menu on the Mac keyboard by hitting the “ESCAPE” key.
This quick access Accent panel is similar to the fast Emoji typing ability on Mac as it’s accessible from anywhere that you can enter text, whether it’s in Pages, Microsoft Office, TextEdit, a web browser and Facebook, Twitter, or just about anywhere else you’d be typing.
If this accent submenu feature isn’t available to you, it’s likely because you either have a fairly old version of system software, or perhaps you disabled the accent menu to favor key repeat instead. You’d have to reverse that to regain the ability.
If you’d rather see every possible accent and diacritic mark laid out before you, the best solution is to use the special character viewer in Mac OS as described here, which lets you browse all accented latin characters as well as other special characters that are available.
Typing Diacritical Marks and Accents on a Mac Keyboard with Keystrokes
If you don’t want to use the accented character menu option, you can also use accent code key combinations. We’ll show the character, and then demonstrate how to type the accent on a character using the series of key presses necessary on Mac.
Remember, the OPTION key is also the ALT key on a Mac keyboard, it is the same key even if the labeling omits option or alt.
ó – Acute: Hold down OPTION key and then press “e”, then type the letter you want to accent, like é
ò – Grave: Hold down OPTION key and then press “`”, then type the letter to accent, like ù
ô – Circumflex: Hold down OPTION key and then press “i”, then press the letter, like ô
ñ – Hold down OPTION key and then press “n”, then type the letter, like ñ
ö – Trema: Hold down OPTION key and then press “u”, then type the letter, like ë
ç – Cedilla: Hold down OPTION key and then press “c”, like ç or Ç
ø – Hold down OPTION key and then press “o”, like ø or Ø
å Å – Hold down OPTION key and then press “a”, like å or Å
Æ – AE Ligature: Hold down OPTION key and then press “‘” like æ Æ
œ – OE Ligature: Hold down OPTION key and then press “q”, like œ or Œ
¿ – Hold down OPTION key and SHIFT key and then press “?” like ¿
¡ – Hold down OPTION key and then press “1”, like ¡
As mentioned before, the other option is to use the Special Character Viewer on the Mac to see all possible options and select a particular accent or special character directly.
Your Apple ID is used for iCloud, iCloud backups, logging into the App Store, making purchases, buying things from the Apple Store, and so much more. It’s a critical component of being an Apple customer and being in the Apple ecosystem, so you’ll want to be sure you have the proper email address configured and linked to your Apple ID. Rarely, some users may need to change the email address associated with their Apple ID, and this guide will walk through how to change the email address linked to an Apple ID.
Note this is focusing on changing the email address associated with an existing Apple ID, it is not the same as changing the Apple ID on a deviceitself, which would mean using a completely different Apple ID. Instead, the same Apple ID is used but the email address is changed, for example if you change your email address permanently than this could be useful. If you aren’t sure what any of this means, don’t mess with any of the Apple ID settings. Similarly, if you have no reason to change the Apple ID email address, then don’t change it.
How to Change Email Address Associated with Apple ID
This will change the email address used to login and use an Apple ID, iCloud, and related features.
Open a web browser on a Mac, iPad, iPhone, or Windows PC (use Safari if there any issues)
Go to https://appleid.apple.com/, the official Apple ID management page and log in to your existing Apple ID*
Choose the “Edit” option on the side of the Account area
Now choose “Change Email Address” under the existing email associated with the Apple ID
Enter the new email address you want to use and associate with the Apple ID in the firstname.lastname@example.org format, then click “Continue”
Wait a moment or two for a verification email to arrive to the new email address, then enter that verification code into the box and choose “Verify”
Click “Done” to save the changes
* If you have it setup to use Apple ID 2-factor authentication you will need to verify a code before being able to login to the Apple ID website.
Again, you are not changing the Apple ID itself that is logged into a device, it is simply changing the email address that is used for a specific Apple ID account.
Once you make this change then all future instances of logging into an iOS device, iPhone, iPad, Mac, iCloud, iTunes, or elsewhere will use the new email address you changed to. The old email address associated with the Apple ID will no longer work and no longer login, you must use the new linked email address to login in the future.
Only make this change if you must do so, it is not to be changed casually. If you change the email address associated with an Apple ID it will make any other device logged in with the prior email address (though the same ID) no longer function. Similarly, if you make the change and then forget your email or password associated with the account, you would have to follow steps to recover a forgotten Apple ID which is a nuisance at best.

Have you ever wanted to know what every single possible terminal command was on a Mac? You can list every terminal command available by turning to the command line. What you’ll see is a significant list of terminal commands with over 1400 possible commands to investigate and use, many of which are either helpful or powerful as we regularly cover with our command line guides. Of course many of the commands listed will have no relevance to the average user, but it can still be helpful to be able to navigate through the list and investigate each command and its respective purpose.
We’ll show you how to list every single terminal command available on a Mac, as well as how to get an explanation and details on each specific command that is shown.
How to Show Every Terminal Command Available in Mac OS
This trick will reveal every single possible terminal command available to Mac OS and Mac OS X. It works in all versions of Mac OS X system software as long as you are using the bash shell, which is the default in all modern releases.
Open the Terminal app found in /Applications/Utilities/
At a fresh bash prompt, hit the Escape key twice
You will see a message stating “Display all 1460 possibilities? (y or n)” type “y” key to start showing every command available
Hit the Return key to scroll through the huge list of commands available
Hit the “Delete” or backspace key to escape the command listing when finished
You’ll see a truly exhaustive list of commands available, some of which may be familiar to advanced users and many commands which even pro users likely have never seen or used before.
Of course you’re now probably wondering what each command might do, or how to investigate what the shown commands do. That’s easy as well.
Getting Info & Explanation for Each Terminal Command
You can easily retrieve information and an explanation on any of the shown commands by using the handy open man page trick, which will launch a manual for the chosen command into a new terminal window. Here’s how it works in the context of the all inclusive commands list on Mac OS:
Right-click on any command listed you wish to investigate and explain further
Choose “Open man page”
The manual page for the selected command will open in a new terminal window to explain the command
You can also use the Terminal app “Help” menu to quickly launch manual pages by searching for a specific command there. Additionally, if you want to find related commands or related instructions, you can use this trick to search manual pages for matches containing a specific keyword or command.
The command line has literally thousands of commands available to use, if you’re interested in learning about specific terminal tricks be sure to read through out command line posts.
