[MacTUG] Recovery mode redo coming to Apple Silicon Macs | iMore

[Marlon Griffith]

"""
When you restart an Apple Silicon-based Mac, you'll hold down the power 
button until the new Recovery options screen appears. You'll then be 
able to select from different actions, like fix your boot drive, choose 
a different startup disk, and more.

There are currently 13 different things you can do when you restart your 
Mac, but each one of those things requires a keyboard shortcut. This new 
boot process will, instead, offer these options on a list.

Apple will also replace Target Disk Mode with something called Mac 
Sharing Mode in Apple Silicon-based Macs. Mac Sharing Mode will turn the 
Mac into an SMB file server, which is a network communication protocol 
for providing shared access to files.

Macs with Apple Silicon will also be able to set different security 
parameters for different volumes. You can have full security for your 
main disk and reduced security for an alternate startup disk.

     In reduced security mode, you can boot any supported version of 
macOS, even if Apple's no longer signing it. And if an app or accessory 
you rely on uses a third-party kernel extension to enable functionality, 
you'll need to use this mode.
