However, threats from for-profit malware hidden in apps or tainted downloads quadrupled in 2019 according to a USA Today report. Traditional malware such as viruses and worms are still minimal to non-existent. Today’s macOS is under increased threat from malware and bad actors.Its most recent macOS Monterey 12.0.1 installer weighs in at about 12 GB - nearly triple in size. The OS X Lion 10.7 installer was about 4.72 GB. The size of its Mac operating system installers has grown considerably over those 10 years too.

It released Mac OS X Lion (10.7) in 2011 and every year since has released a new major version. Apple has been on a 1-year major release cycle for its Mac operating system for the past 10 years.

So I’d appreciate any thoughts or ideas for troubleshooting. ‘sharingd’ doesn’t seem to be one of the “usual suspects” that eats CPU. I did a bit of Googling and this does not appear to be a common problem. Not the kind of behavior I like to see in a brand new Mac. Second failure apparently resulted in a panic with an invitation to send the log to Apple. It survived a macOS reinstallation (to 11.1.2) but it does go away in Safe Mode.Īnother anomaly, which may or may not be related: updating from 11.1.1 to 11.1.2 failed TWICE, after apparently going through all the motions (restarts and progress bars) properly. Killing the process only works temporarily - it respawns in seconds, maybe a minute at most. A client’s M1 MacBook Air has ‘sharingd’ constantly gobbling up 80%-90% CPU. I have a vexatious problem and hope someone can provide some ideas. Thanks for the writeup and the pointer to “Apple Platform Security.” I have updated my page on M1 boot modes to include this valuable addition, which makes me even more impressed with 1TR, although maybe this fallback would be better named 2TR. But for all other purposes, this is just as good as 1TR, and is identical. Apple explains that this is because “LLB doesn’t lock an indication into the Boot Progress Register saying it is going into recoveryOS”. What you then get is every bit as good as regular 1TR, with one significant exception: you can’t set the system security state using the Startup Security Utility. This works reliably on an M1 MacBook Pro, but I’ve so far been unable to get it to work at all on my M1 Mac mini, but maybe I’m just not doing it right.

In practice, I’ve found this requires you to press the Power button twice in rapid succession, and on the second press, instead of releasing the button, hold it pressed until recovery options are reported as loading.

To boot into that, instead of just holding the Power button until 1TR starts loading, you should “double-press and hold the power button”, according to the guide.
How to rebuild a mac mini 1 software#
If you need your M1 Mac to enter 1 True Recovery (1TR), Recovery Mode, but that fails, there’s a second copy of the software required for 1TR “for resiliency”. In the course of doing that, it reveals that these new models have a boot mode which doesn’t appear to be documented anywhere else, but which could prove a Mac-saver: Fallback Recovery OS. One document every serious Mac user should read and refer to repeatedly is the Platform Security Guide, which Apple has just revised to give all the gory details of how M1 Macs start up. However sparse Apple’s documentation might have become, when it does explain things properly, it’s amazing what’s revealed in the detail.
