There are many different potential solutions for Macs which are affected by this bug.

Because of the way that these updates are pushed, your Mac won’t see the older version, and even if it did, simply trying to install it won’t force it to be downgraded from 1.68 to 1.67.

Apple pulled that update early on 24 October, but unfortunately that doesn’t force affected Macs to be downgraded. This appears to be the result of a bug in MRT 1.68. For the moment, if your Mac successfully updated to the new version of MRT without suffering these problems, there’s no reason to suspect that it will develop them later. It’s not clear why this is, and there’s no obvious pattern to these problems. Many Macs which were updated to MRT 1.68 haven’t been affected at all. Although affected Macs aren’t completely unusable, they’re severely affected by this. MRT keeps crashing and being automatically restarted, and this affects overall performance. The Mac becomes sluggish, and looking in Activity Monitor normally shows two processes, MRT and trustd, taking large amounts of CPU. Affected Macs, which can be running any version of macOS from El Capitan to Catalina, suffer severe problems running the new version of MRT. Unlike XProtect, whose data files are used on demand, MRT is normally run in two situations: shortly after it has been updated, and soon after a Mac starts up. Some, but by no means all, Macs then suffered a problem as a result of the new version of MRT. That doesn’t happen immediately, but for Macs in daily use, that means that most will have been updated by 2359 UTC on 20 October.

Macs which run with Software Update set to Install system data files and security updates then automatically download and install those updates. These normally happen every two weeks or so, and are silent in that Apple doesn’t announce them, or even admit that they’ve happened. Some time before 2200 UTC on Monday 19 October, Apple pushed routine updates to its security tools, XProtect and MRT. This article explains what happened, and what you can do about them. The installation process will begin.Last week a great many Mac users were struck by one or both of two serious problems. If you booted from a functioning recovery partition, click the “Reinstall macOS” button. With your information wipe complete, you are now ready to reinstall macOS. If you choose three or five passes, you might want to leave this running overnight. If you opted to wipe your drive securely, this might take a while-30 minutes to an hour is not unreasonable for one pass. Just give your drive a name (I recommend “Macintosh HD”, just for consistency’s sake), then click “Erase” to start the overwriting process. You only need to write over a drive once to securely wipe it, but if you’re paranoid you can also wipe it three or five times.Ĭlick “OK” once you’ve decided, but remember: if your Mac has a solid state drive, you do not need to use these options. Now move the dial up, to randomly write data over your entire drive. You still need to wipe the drive, however, or your files will remain in place, so skip to the end of this step to do so.) (If your Mac has a solid state drive, you can skip this part: your SSD will already securely erase files thanks to TRIM.
If you’re wiping a mechanical drive, click “Security Options” in the window that pops up. We recommend backing up files before you do this, just in case, but otherwise you’re ready for step three. Your user accounts and files will stay exactly where they are-only your operating system will be overwritten. If you want to re-install your operating system, but leave your files in place, you can skip this step.

You can access recovery without a partition using Network Recovery: hold Command+Shift+R while turning on your Mac and it will download the Recovery features for you. Failing that, you can create a bootable USB installer for macOS Sierra, and boot from that by holding “Option” while turning on your Mac. If neither of these options work, don’t panic! You’ve got a couple of options yet. On those devices, hold “Option” while turning your computer on, then select the recovery partition instead. If you’re using an older Mac (from 2010 or earlier), there’s a chance that you can’t use Recovery Mode.
