To use any of these key combinations, press and hold the keys immediately after pressing the power button to turn on your Mac, or after your Mac begins to restart. Keep holding until the described behavior occurs.

So - try this Quit all apps from the Dock, close all finder windows. From the Apple menu, choose Force Quit. Force Quit everything that's in that folder, other than Finder. Restart your Mac. Which apps, if any, launch automatically this time?

• Command (⌘)-R: Start up from the built-in macOS Recovery system. Or use Option-Command-R or Shift-Option-Command-R to start up from macOS Recovery over the Internet. macOS Recovery installs different versions of macOS, depending on the key combination you use while starting up. If your Mac is using a firmware password, you're prompted to enter the password.
  
• Option (⌥) or Alt: Start up to Startup Manager, which allows you to choose other available startup disks or volumes. If your Mac is using a firmware password, you're prompted to enter the password.
  
• Option-Command-P-R:Reset NVRAM or PRAM. If your Mac is using a firmware password, it ignores this key combination or starts up from macOS Recovery.
• Shift (⇧): Start up in safe mode. Disabled when using a firmware password.
• D: Start up to the Apple Diagnostics utility. Or use Option-Dto start up to this utility over the Internet. Disabled when using a firmware password.
• N: Start up from a NetBoot server, if your Mac supports network startup volumes. To use the default boot image on the server, hold down Option-N instead. Disabled when using a firmware password.
• Command-S: Start up in single-user mode. Disabled in macOS Mojave or later, or when using a firmware password.
• T: Start up in target disk mode. Disabled when using a firmware password.
• Command-V: Start up in verbose mode. Disabled when using a firmware password.
• Eject (⏏) or F12 or mouse button or trackpad button: Eject removable media, such as an optical disc. Disabled when using a firmware password.

If a key combination doesn't work

On your Mac, open System Preferences (from the Apple menu at the top-left of the screen), or use Terminal. Click Users & Groups; Click the Login Items tab; Here you will see the apps that will open automatically at login. If Mail is there, you can stop it from opening automatically, select and and click the minus icon to remove it. Mac booting up to a black screen could be caused by conflicting startup items. You may try and fix it with a tool that we created here at MacPaw. Download CleanMyMac X (Apple-notarized version) to check your Mac for software issues and system junk. With it, you can disable startup items and remove old and redundant apps.

If a key combination doesn't work at startup, one of these these solutions might help:

• Be sure to press and hold all keys in the combination together, not one at a time.
• Shut down your Mac. Then press the power button to turn on your Mac. Then press and hold the keys as your Mac starts up.
• Wait a few seconds before pressing the keys, to give your Mac more time to recognize the keyboard as it starts up. Some keyboards have a light that flashes briefly at startup, indicating that the keyboard is recognized and ready for use.
• If you're using a wireless keyboard, plug it into your Mac, if possible. Or use your built-in keyboard or a wired keyboard. If you're using a keyboard made for a PC, such as a keyboard with a Windows logo, try a keyboard made for Mac.
• If you're using Boot Camp to start up from Microsoft Windows, set Startup Disk preferences to start up from macOS instead. Then shut down or restart and try again.

Remember that some key combinations are disabled when your Mac is using a firmware password.

To have a FaceTime call with one other person, you need a Mac with OS X Lion 10.7 or later, a broadband Internet connection, and a built-in or connected microphone or camera. Or use your iPhone, iPad, or iPod touch.

To call a group of people, follow the steps in Use Group FaceTime on Mac.

Start a FaceTime call

The person you're calling doesn't need to have the FaceTime app open, but to receive the call on their Mac, iPhone, iPad, or iPod touch, they do need to be signed in to FaceTime on that device. You can then call them using any phone number or email address they set up for FaceTime.

Start a call from the FaceTime app

Open the FaceTime app and enter the email address or phone number of the person that you want to call. If the person is in your Contacts app, you can enter just their name. Then click the Audio button or Video button to call.

You can also just ask Siri to ”FaceTime John” or ”FaceTime audio Lisa,” for example.

Start a call from the messages app
