To boot from an external disk, Apple silicon Macs need them to have an Owner. Here’s how to investigate ownership, and how it works.
M1
From choosing cables and hubs to connecting displays, fast SSDs and other devices. Everything you wanted to know about Thunderbolt.
Apple silicon Macs are better-equipped to prevent and deal with disaster. Restoring in DFU mode is extremely unusual, and more powerful than anything you can do with an Intel Mac.
The M2 Pro and Max gain an extra two Efficiency cores, compared to their M1 equivalents. What effect will that have on their performance, and what of the M2 Ultra?
If there’s a problem, you may try Recovery mode. What do you do when that proves to be a problem? Solutions for Intel and Apple silicon Macs.
Is reinstalling macOS still a useful solution to problems? What about installing macOS updates, or resetting the NVRAM and SMC?
Rosetta 2 is key feature for the transition to Apple silicon, and is also available to run Intel x86_64 binaries in virtual macOS and Linux (in Ventura).
Now feature-complete with support for shared folders with the host Mac, and everything is in place for Rosetta 2 translation of x86_64 binaries within the VM.
Now fully supports shared folders, on Ventura hosts running Ventura in a VM. This gives access to faster storage, and to iCloud Drive as well.
With Unified memory, don’t you simply add the main and graphics memory sizes from your Intel Mac to determine how much your Apple silicon Mac needs?
