I have a 2016 MacBook Pro, with CateLina I’ve noticed messages regarding certain apps that they won’t be compatible with a future version of the MacOS. One is my Scansnap document scanner. Would that be this version? Yes, I will check the manufacturer (Fujitsu) web site to look for compatibility info, but though I’d ask here too.
Thanks.
There are plenty of reasons not to install the most recently released major version of an operating system.
Device driver compatibility is one clear issue.
However, there are basic issues. Like any operating system, major updates of macOS typically have lots of bugs. Over time, many of these bugs are addressed in minor updates.
Thus if you want a smoother update experience, one highly effective method is simply to wait several months before making the jump.
I held off upgrading a couple of iDevices from iOS 12 to iOS 13 for ten months. More notably, I am still running Mojave on my Mac mini 2018. I will upgrade to Big Sur but most likely I will wait until Q2 2021.
Based on Apple's software QA track record over the past few years, I have zero interest in upgrading to Big Sur today. As with Crapalina, I will likely do a test Big Sur install on a "disposable" external SSD. However in my mind, Big Sur is still beta quality at best. All of Apple's x.0.0 macOS releases since Sierra have been resolutely beta quality upon release.
For Crapalina, I'd say that 10.15.0 was late alpha quality, closer to Beta 1 than Beta 6.
This isn't really Apple specific. I waited four months to install Windows 10 May 2020 on a couple of Wintel boxes. I held my main PC held back another month.
