Sequoia’s macOS VMs and Apple ID, USB storage and other devices, number of concurrent VMs, nested virtualisation, and how to run Sequoia beta in a VM on Sonoma.
virtualisation
It’s over 10 years since Apple stopped providing documentation such as programming guides. Some of the consequences on concurrency, virtualisation, AI and SwiftUI are considered here.
T1 and T2 chips in Intel Macs, integral in M-series chips, used in Sequoia’s virtual machines at last, and an essential feature in Private Cloud Compute.
When will we learn about macOS 15? What important changes will it bring? When will the public beta be available? Will there be any new Macs?
Two watersheds that could occur in macOS 15: that it only supports Macs with Apple chips including an Arm processor, and that it opens access to older versions of macOS on Apple silicon.
Secure Boot and its 5 stages, the SSV, support for external bootable disks, the SEP, Recovery, and lightweight virtualisation.
Virtualisation of macOS on Apple silicon does deliver performance that’s impressively close to that of the host. Here are the figures to demonstrate it.
Sparse bundle passwords, shared folders in macOS VMs, and security updates for VMs, are all important fixes. But none for the Finder.
The update to bring macOS Sonoma to version 14.3 isn’t large, although it has some compelling security content […]
In a wide range of in-core tests, CPU performance in VMs is close to that of code running native on the host, and M3 VMs are faster than M1 native. With one significant exception.
