I have decided to move this post up, whenever I want to comment on an OS release from Apple. I will not include every release, but try to add my best recommendations to how it looks.
I encourage to look at this page for the latest macOS releases: https://en.wikipedia.org/wiki/MacOS_version_history
macOS Monterey 12.2.1 is out as well as iOS/iPadOS 15.3.1 (2022-02-10)
… and also Big Sur & Catalina security updates on 2022-02-14.
Updates uncludes security fixes, but for Monterey also general bug fixes.
We now look forward to Monterey 12.3 which will remove python as well as kernel extensions.
macOS Big Sur 11.6 is out as well as iOS/iPadOS 14.8 (2021-09-13)
… and also Catalina security updates.
So we got new security updates again, and these are very important. Everyone should update. If not it could mean that devices are compromised and someone outside has access to data on the device.
macOS Big Sur 11.3.1 is out as well as iOS/iPadOS 14.5.1 (and iOS 12.5.3)
These are mainly security update. And very important to update!
macOS Big Sur 11.3 is out as well as iOS/iPadOS 14.5
These are at the same time very important security updates, and for iOS/iPadOS it also includes a security setting under privacy.
If anyone is still evaluating the need to upgrade from Catalina or not, I would say that since 11.2.3 it is safe to switch. Catalina is still safe and secure, but I would not expect much of any problems to occur if upgrading now.
With 11.3 a lot of security fixes has been applied, as well as a little polish on the GUI. A very important fix is for VPP apps, sent out from MDM solutions. They should finally fully work. I have been tracking lots of problems with this, so look forward to see this in action.
Apple has upgraded the privacy features. Now you have to enable the ability for apps and web sites to track you. By default it is off, and Apple we do what they can to prevent tracking of your device (like unique identifier and other internal parameters). Apple has earlier on improved on cookie tracking in Safari, but this is mostly towards apps (like Facebook and Google), so that identification and isolation of your device is not possible.
MacOS Catalina 10.15.5 is out (with Mojave Security Update 2020-003)
These updates fixes a lot of security issues for macOS. So it is a rather important update.
But it also includes some features and fixes. One of them is that we on Mojave no longer can ignore the upgrade to Catalina. That is simply not supported anymore.
Same thing for Catalina, so whenever 10.16 is released we cannot use the ignore feature to prevent this.
I’m not in favor of postponing updates, but I understand workflows and often it can be quite a hassle to fix everything on all of Apples releases.
It’s this command that is not working anymore:
softwareupdate --ignore "macOS Catalina"
So we have to prevent this using some other method instead…
