Your Mac unexpectedly restarts, and a little after logging in you see a Panic Alert. Before sending that to Apple, save a copy and follow this guidance, including how to read a panic log.
virtualisation
Running older macOS, support for Intel apps and kernel extensions, booting from an external drive, Boot Camp and Windows support, cloning, and startup key combinations.
How to create and set up macOS VMs for virtualisers. The structure of a VM, creation and first run explained. How to enhance it, and how to run it in isolation.
Which versions of macOS can run in a VM? Can they run Intel apps too, and Intel macOS? How well do they perform? Can they access iCloud and run App Store apps?
Which versions of macOS can you ‘dual boot’, should you install them all on the internal SSD, or is a bootable external disk better, and when would you need to virtualise?
From the start of the fourth cycle in M4 Macs and the smallest ever, through the omission in macOS VMs, and QuickLook shortcomings, to the stealth firmware update.
Can you promote threads set to run on E cores so they run on P cores instead? Can you demote threads set to run on cores so they run in the background on E cores?
The macOS 15.2 update includes the second phase of AI support for Apple silicon Macs, introducing the Image […]
Discovering whether using more threads makes a task faster gives insight into where its performance is limited. How to use a VM to investigate this.
A bug, most probably in the early part of kernel boot in guest macOS, prevents M4 Macs virtualising macOS prior to 13.4.
