macOS 12.2

Juli Clover (download):

macOS Monterey 12.2 is a bug fix update, and Apple’s release notes have no information other than generic bug fix information. We don’t yet have a full list of security updates, but we do know that macOS Monterey 12.2 addresses a Safari bug that could cause your recent browsing history and details about your identity to be leaked to malicious entities.

Howard Oakley:

Details of security fixes in macOS 12.2 are given here. They include one kernel vulnerability, and total 13.

Update (2022-01-31): Howard Oakley:

Initial quick testing unfortunately demonstrates that one major bug in 12.0.1 and 12.1 hasn’t been fixed: the Finder still leaks memory badly when its Find feature is used. This doesn’t appear to have even been reduced.

Howard Oakley:

This memory leak appears to affect all models of Mac, both Intel and M1, running any version of Monterey from its initial public release 12.0.1 to the latest update 12.2. As it affects one of the key features of the Finder, if you use the macOS GUI sooner or later you’re likely to come across it, and for some users it’s severe.


The (literally) big danger is typing one character in and leaving the search to run: do that once, and the Finder’s memory use could readily rise into several GB.

Howard Oakley:

What I find unacceptable about Monterey 12.2 is that it still – three months and two updates after 12.0.1 – suffers a large and severe memory leak which is easily reproducible and renders a key feature in the Finder almost unusable.

Joe Rossignol:

Apple released macOS Monterey 12.2 earlier this week, and some Mac users who have installed the software update are experiencing excessive battery drain during sleep mode, seemingly due to Bluetooth accessories frequently waking the computers.

Update (2022-02-08): My iMac has been having serious problems since updating to macOS 12.2.
