Thought I'd set Adaptivity up on one of my old computers running 10.15.7, looks like the App store thinks it should run there.

It immediately throws the dialog box: “Adaptivity quit unexpectedly”. I rebooted and then deleted the app and redownloaded it from the App store. Is there something else to try?

I guess I could just not use it there (it works great on my M1 iMac) but that seems like giving up 😆

@dxzdb Hmmm. I don’t have a machine running that far back to test with. Maybe there’s a bug in the app that tries to call a newer API but I would expect Xcode to catch that sort of thing at compile time. I have been having a lot of health problems and haven’t done any work for about 6 months. There’s not really anything I can do to investigate. Sorry!

@geoffhackworth Ah, sorry to hear about your health issues, hope you feel better soon. Please disregard the below if you'd rather not read about things related to code.

I’ll pass this along only as a “huh - that's interesting sort of thing”. I opened the package contents and clicked on the AdaptivityA Unix executable in the MacOS folder. It runs and crashes with the same dialog box but the console barfs out some interesting things about a Class called HNCSmartSearchMatcher.

@dxzdb The problem is with [UISceneConnectionOptions shortcutItem] not with HNCSmartSearchMatcher. The latter is because the same class is found in two of my frameworks used by the app and is benign. The former seems to state there’s no property called shortcutItem on a UISceneConnectionOptions in that version of macOS. The docs claim it exist from macCatalyst 13.0 onwards which I thought corresponded to macOS 10.15. But you said you were on 10.15.7 🤔 Maybe the API is incorrectly versioned 🤷‍♂️

@geoffhackworth interesting -
Stackoverflow confirms someone else struggling to correlate macCatalyst version to macOS version. And that 13.0 = 10.15 & 13.4 = 10.15.4

probably Apple isn’t testing this far back either.

Toss this on the pile of Apple things that don’t just work. Glad they canceled the car though maybe they can focus on software quality. 😏
