Have you turned on FileVault 2 encryption? If you have, you can enable your third account by doing the following:
Open System Preferences
Click on Privacy & Security.
Click on the FileVault tab.
There should be an Enable users... button showing in the FileVault preference pane. Click it and you should be given the opportunity to enable the third ...
This can be done without 3rd party app. Simply open System Preferences.app -> Security & Privacy -> Show message when the screen is locked. Here are the steps:
Open "System Preferences" (located in you applications folder)
Select "Security & Privacy"
Unlock the padlock
Set the lock message
You can SSH into another Mac and use screencapture in the shell.
Enable remote login in the sharing preferences on the other computer
sudo screencapture ~/Desktop/screenshot.png
Yes, you can do this by using Terminal. More specifically:
Open the Terminal app (by default this is located in the Utilities folder within your Applications folder)
Now copy the following command and paste it into your Terminal window:
sudo defaults write /Library/Preferences/com.apple.loginwindow LoginwindowText "This Mac was kindly donated by X."
This can be accomplished using a feature of the unix based login system that assigns a program to run on successfully login. Normally users in OSX have their shell defined as /bin/bash. The OS login window will actually make sure people have a usable shell before showing them on the login screen.
You can disable a user — revoking both their ability to login ...
I've fixed it! You'll have to edit the dune HEIC picture though. If you're willing, follow these steps:
1) Go To: /Library/Desktop Pictures/
2) Find the file called "Mojave.heic"
3) Save a copy as a backup somewhere else
4) Select the picture you want to have instead
5) Edit image values (DPI, size, etc.) to fit
6) Rename this edited picture as Mojave....
This works on OSX 10.9 Mavericks, with a keyboard layout that I created with Ukulele. Assuming that you have the layout already installed in your system, log into your account and make your custom keyboard layout active.
Open a terminal and run the following command:
cp /Library/Preferences/com.apple.HIToolbox.plist /tmp/
If you intend to use a text ...
I found this old MacWorld tip, that suggested running the Setup Assistant again:
sudo /System/Library/CoreServices/Setup Assistant.app\
At first I thought this wasn’t supported in Lion anymore as running this command didn’t seem to have any effect. Only after posting this question, I noticed there’s a typo in the command. ...
The clue was from activating the voice-over, which eventually tells you:
Ctrl + Option + Shift + Down Arrow simultaneously followed by left/right to choose user,
You don't need to activate voice over for this to work.
That is completely non-intuitive: a simple tab would solve this completely.
If you find >console not working, newer OS have disabled it by default.
A quick command line modification of the preference will re-enable it:
sudo defaults write /Library/Preferences/com.apple.loginwindow.plist "DisableConsoleAccess" NO
Not sure if you set it in the correct place, but the setting should be at:
Choose Apple menu > System Preferences, click Security & Privacy, then click General.
Select “Require password… after sleep or screen saver begins.”
Click the pop-up menu and choose the time that passes before a password is required.

>console works on OS X 10.7.5 , 10.8 and 10.9
I have just tested >console and was able to log into the console without issues running the above OS X's.
I would say there is something else wrong with your system if you cannot get to the basic console.
I would also check your console logs and activity monitor as specified here.
I have not tested this myself, but maybe this link will help. Grab 'impossible' screenshots
OS X includes a nice command-line screen capture utility named, simply enough, screencapture. While there’s not a ton of documentation on this program, man screencapture will give you the basic options. Once you’ve used ssh to connect to the Mac whose screen you ...
This indicates you either enabled the root user or you connected to a directory service (Open Directory or Active Directory) for the ability to login with network accounts.
Open System Preferences > Users & Groups > Login Options
Look for a Network Account Server in the main pane of Login Options and edit accordingly if one is ...
From OS X: About FileVault 2:
Users not enabled for FileVault unlock will only be able to log in to that Mac after an unlock-enabled user has started or unlocked the drive. Once unlocked, the drive remains unlocked and available to all users, until the computer is shut down.
In order to enable the migrated user for FileVault:
Log in with the account ...
You can set the text from Terminal by running
sudo defaults write /Library/Preferences/com.apple.loginwindow LoginwindowText "your text here"
The text is displayed in three lines with a max length of 68 characters each so it it might help to pre-select/format the quotes to match these limitations.
Expanding on Leonard's answer:
You can do this by replacing the Mojave.heic default desktop background. This does not require disabling SIP, as it's in /Library.
Back up /Library/Desktop Pictures/Mojave.heic by copying it to Mojave.heic.orig or similar.
Get your new image and scale/crop it to exactly fit the display. If you don't know your screen ...
Though I didn't experience the blue screen, this does sound a lot like the issue that I described in Boot hangs on grey screen (even when booting from USB drive with fresh OS X install) (I posted as a different user since I didn't immediately have my StackExchange credentials handy).
It seems there are an increasing number of people experiencing failure to ...
There is likely an issue with something specific to your profile. You can verify this by booting into safe mode:
Hold Shift while booting, it will take longer than usual, and eventually the startup screen will say safe mode. This disables a lot of things that run at startup on the system AND in your profile. If you can then get into your profile something ...
I tried the PRAM many times and it didn't work. Thank you Reve. Your link solution was the one that worked. Dunno why your solution was down voted.
I am copy pasting the text:
In the three years of using my MacBook Air, I have never had any major problems with it. It was totally reliable, even after I accidentally spilled coffee on it. However, the update ...
It happened to me too. I just typed my login password, assuming the login screen was there and I could not see it. That worked like a charm and I booted into my normal Desktop. After a reboot it did not occur again.
Ok guys - I had the same issue with my 2008 iMac and Apple support just walked me through the fix...
Shut the computer down by holding the power button for 10 seconds
Restart the computer and press shift at the same time until you see the progress bar start moving
Once you reach the point where your screen goes dark and you see the cursor, type the first ...
It's certainly not an elegant solution but you can use the VoiceOver screen reader to accomplish something similar - at least to move the focus. VoiceOver is used by blind people to work the computer without a mouse at all and by using voice output and keyboard shortcuts.
At the login screen, press Command+F5 to enable VoiceOver. Your computer should start ...
