macOS Catalina 10.15.7 Update is now Available!
For the first time since Mac OS X Snow Leopard, Apple has progressed past a .6 point release! I’m very happy with this change, as it’s easier to understand dot releases compared to supplemental updates. This is the 21st update overall for macOS Catalina.
UPDATE! 9/29/20 – I just posted an article talking about the Catalina 10.15.7 Update accountsd process using 400%+ CPU.

UPDATE! 9/27/20 – A few reports are coming in that the 10.15.7 update is causing some problems with the accountsd process. After the installing the 10.15.7 update, accountsd runs up to 400% in Activity Monitor. The issue might happen for some users that are using iCloud for Drive, Mail or Cal. Other reports say the issue can happen if you are using internet accounts with Gmail. This issue causes system slowness until resolved. Most fixes say to log out of iCloud or Gmail then restart.

Catalina 10.15.7 Update Changes
My father has had 3 Kernel panics on his Late 2015 27″ 5K iMac since installing the 10.15.7 update. All are that graphics driver wake from sleep issue that never seems to be fully resolved with each attempt Apple makes to fix it. Definitely a regression. I can’t recall if this driver issue affected this specific hardware model in prior affected Catalina builds.
