Since you're a C1 user, be aware that the last couple of C1 versions have supported only a couple of earlier OS versions.

My solution, which I've used for years, is to upgrade the operating system only when I need to, which is usually driven either by the need to get a new computer, or when one of my needed apps needs a newer OS to run (this was the case with Affinity v2 apps and Capture One 23). Two gave notices that an update was required (fortunately those developers are still around!), but most are just dead dead. I was surprised and disappointed that a number of my 64-bit Intel coded apps won't run. That leaves us in a spot if the app developer's no longer around, or the current upgrade is subscription-only, among other things.Ĭurrent example: I just took delivery of a new Mac that requires the current OS (in fact, the latest OS update was released the day my machine was delivered). One of the issues I have with Apple is that they'll change OS underpinnings to suit their developers, and that can break apps. Fortunately Capture One is already a Universal Binary, but lots of other apps aren't. If the rumor's true, the Intel Mac Pro gets replaced this year, which means that sometime in the relatively not-to-distant future (whenever Apple decides), all apps coded for Intel only will die. Also, when Apple began their transition away from Intel CPUs, they said that they'd support Intel apps for at least 2 years from when the last Intel machine was replaced. As mentioned, macOS 10.15 killed all 32-bit apps.

Do Mac OS updates tend to break usage of older software licences that have not been updated to support them?
