Just for the record: the same problem occurs with Release along with an interpreter.
How I fixed this:
I had the same issue as the original poster after downloading from Mac App Store. Turns out the version on there is not the Catalina compatible version - it was version 1.65.1. I downloaded the âinterimâ version 1.28 from Inform7.com and replaced the one I had. That seemed to do the trick.
This is still the problem, though the actual Catalina (macOS 10.15) inform version number that works is 1.68.1.
Could we at least update the app description in the Mac App Store to say that it wonât run on Catalina, and where to download the right version?
Also, anyone downloading Inform 1.68.1 for Catalina should be aware that testing extensions and dark mode are still broken. See Inform on Mac - no cursor? and MacOS Inform 1.68 can't test extensions?.
OK, I downloaded the latest (âinterimâ) version directly from the Inform website, and it had problems with dark mode. I then got the version from the App Store an was delighted that dark mode worked great, but then sickened to realized that projects wonât compile at all (something about 32-bit vs 64-bit). Itâs lunacy that a âbrokenâ version can exist on the app store like this for YEARS (since 2019 at least) without being fixed. Ugh.
I was so excited to begin working with Inform, but I cannot seem to find a version that doesnât have one problem or anotherâŠ
An unofficial Mac Build has fixes for those. (Iâm not a Mac person and canât vouch for it personally, but others seem to have had success with it.)
