Mac startup key combinations

 https://support.apple.com/en-us/HT201255

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.

• 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-D to 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.

How to Turn Your Smartphone Into a Webcam

Use your phone camera as a webcam

The first is the NDI HX Camera app from NewTek
NDI Virtual Input utility that tricks your video software into accepting the NDI input as a webcam is only available in NDI Tools for Windows

If you’re wanting to use an Android phone as a webcam, one of the most polished options we’ve found is DroidCam. Again, this only works with Windows, via the desktop client, but setup is simple—launch the Android app and it gives you an IP number that you can type into the Windows client, and you’re up and running.

Facebook's "Family"

The whole family... Facebook doesn't disclose revenue for its individual "children," bundling their financial info instead into their so-called "family of apps."

• Facebook: The old parent, always cracking dad-jokes and sharing pictures of ferns and grandchildren.
• Instagram: The too-cool-for-school teen child. Super fashionable, always taking Valencia-filtered selfies, and perennially drinking craft coffees while chilling on a white-sand beach.
• WhatsApp: The cool, foreign cousin that's always studying abroad somewhere and reading Kant.
• Messenger: The distant aunt that you always forget exists but go to when you need some random specific thing.
