![]() ![]() If you’re thinking of installing betas on an Apple Silicon model, beware that process requires another Mac running Apple Configurator 2 and restoring it in DFU mode. Apple explains how to do that, and you should read that account carefully before making any decisions. If the worst comes to the worst, you could end up having to restore that Mac to an older version of macOS. Consider carefully what havoc they could produce if there’s a bug which affects other storage used by that Mac, and its backups. All you can then do is wait for another beta, or maybe the final release in the autumn/fall, which does update the firmware to something more compatible.īetas also normally come with updated versions of key components such as the APFS file system and Time Machine. Undoing that is hard enough for an Intel Mac with a T2 chip or an Apple silicon model, and it’s simply not possible on Intel Macs without a T2 chip. Betas usually involve firmware updates, so even if you install the beta on an external disk, it will change your Mac’s firmware. Never, under any circumstances, install a beta of macOS on any Mac you rely on for production. Although that’s unlikely to happen, it’s a risk you’ve got to be prepared for when you install a beta of macOS. ![]() The first question you should ask is whether you have a suitable Mac which you could afford to lose completely for a while, as a result of a problem with the beta. ![]() So should you risk or resist Apple’s tempting offer? In the next week, maybe on Monday to celebrate the fourth of July, Apple is going to make the first public beta-release of Ventura available to those brave souls who join its beta programme. ![]()
