It could just be a hangover from my first experience installing Catalina on a 15" MBP that I was already unhappy with. It didn’t take, and I had to wipe it and reinstall from scratch. I can’t remember the last time that I’ve had to do that. I traded the 15" for a 16" and there are a few bugs, but things have been better.
The main feature that I was looking forward to was Sidecar for the iPad, but I’ve found that I don’t really use it that much. I didn’t use iTunes and don’t use the apps that were split out of it. I like dark mode on my phone, but can’t stand it on the Mac.
The thing that bugs me the most are the new security features. I open an app to do a thing, just like always, and then I have to dismiss a dialog box to let it use my Documents folder, and then another one to let it access a hard drive, and then go to the system prefs and type in my password and click a box to let it use the accessibility features. And then, somehow all of that gets screwed up and I have to do it again. I would swear that I’ve had to let some apps access my Documents folder three or four times.
Maybe I’d feel better about it if I had skipped the year 2019. My hardware dissatisfaction was compounded with software troubles which left me with bad feelings that are starting to even out a bit.
