If it has been previously formatted using an older version of macOS, I recommend re-formatting it with 11.4 or later if possible. Connect the disk to an available port on your M1 Mac, which could (subject to its compatibility) include a dock or hub.The procedure for installing macOS on an external disk attached to an M1 Mac runs: So there remains a small risk of disaster. ![]() You can reverse that if it has a T2 chip or an M1 SoC, as I mentioned above, but for a plain Intel Mac the only recovery would be a subsequent firmware update which could be tricky or even impossible to install. This still carries a risk, in that your Mac may install a flawed firmware update. ![]() You’ll need a Mac running macOS 10.15.6 or later, a USB-C to USB-C charge (not data) cable, and of course a second Mac.ĭon’t install the upgrade on your internal diskįor M1 Macs in particular, this should be a good choice, and is how I do all my summer beta-testing each year. Before considering this, install Configurator 2 and study its Help book. The only exception to this is for a Mac with a T2 chip: you can then use Apple Configurator 2 to update the firmware in the T2, and erase recoveryOS and macOS on the Mac’s internal storage. Although you can roll back macOS, you can’t install older firmware. ![]() One important consideration before deciding to press ahead and upgrade an Intel Mac you can’t do without is firmware. That may force you to compromise, which is what the rest of this article is about. The snag at the moment is that many need to test on both Intel and M1 Macs, and relatively few have spare Macs covering both architectures. The golden rule of beta-testing is that you should never even consider installing any beta-release on a production system, using only systems which you can afford to have fail. The traditional trick of cloning your current internal storage to an external disk, so that you can clone it back if you need to roll back macOS, should still work on an Intel Mac, but is likely to fail on an M1 model, leaving it stuck and dysfunctional until Apple provides an update which isn’t so flawed. How should you prepare for the possibility that any of these could prove a lemon? How can you upgrade while retaining the ability to roll back to your current macOS? With WWDC almost upon us, the imminent first beta-release of what’s expected to be macOS 12, and 11.5 also in beta, many are now wondering how best to install these, or even macOS 11.5 when it’s released. ![]()
