As macOS doesn’t have a dashboard to warn you of dangerous security settings, it’s worth checking them. Here’s what to look for, and how to correct them.
Secure Boot
Central to the secure design of Apple silicon is Secure Boot, the intricate mechanism that ensures everything in […]
macOS has changed fundamentally. So has troubleshooting it. Secure Boot, the SSV, and Gatekeeper checks bring changes in strategy.
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.
Why can some with Apple silicon Macs create and boot from external disks, while others seem doomed to failure?
Maybe you’ve just forgotten the password, or perhaps the owner/user of the Mac is no longer able to enter it. How to restore access to different models.
in Mac OS 8 and 9, you could patch the system direct. OS X was harder, and became sprawling and interdependent, encouraging users to reinstall macOS. That has now ended with the introduction of the SSV.
Assigning ownership to an external bootable disk doesn’t always work in Recovery mode on an M1 Mac. But there’s an easy workaround.
M1 Macs are different, as they always start booting from their internal SSD. Basic configurations are simple, reliable with well-established disaster recovery methods.
A strange volume named xART or xarts, secure memory management, and long random numbers: how they fit together to protect against replay attacks.
