How to create and configure a Sequoia beta to run in a virtual machine on an Apple silicon Mac, either in Sequoia or Sonoma, and a surprise in its features.
virtualisation
What you need, what the risks are, and how to ensure you don’t have problems if things go wrong. Includes coverage of VMs and more.
All about Mac firmware, from PowerPC Open Firmware to Apple silicon’s LLB and iBoot, and what the rules are for updating firmware.
This weekend we’re in the Lake District. Wouldn’t it have been simpler if, rather than preparing a notebook, all I needed was a VM with all my apps pre-installed and ready to go?
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.
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.
