That article seems misinformed. I just downloaded and ran OpenSCAD (referenced as a now unusable unsigned app) using the normal method of running unsigned apps: Try to Open, Go to Privacy & Security and allow.

Perhaps it only affects some users. If it was intentional, I'm not sure why this still exists: Open a Mac app from an unknown developer - Apple Support

SOLVED (for my case): After updating to 15.1, I had this problem, too. However, note that my case is: I have self-written, unsigned java apps in the Dock. These Apps are xxx.app folders with Contents/ and in there is also a self-written Info.plist file. This Info.plist contained too many entries, partly with no/incorrect data. Removing most of them and only using CFBundleExecutable, CFBundleIconFile, CFBundleDisplayName solved my problem. However, for my case here, the main executable is merely a shell script in the MacOS folder, so for your problem that may be more complicated. In any case, it might help to look into the Info.plist file and try to fix (or remove) something there.

Remove the ones you can't from the Taskbar and fire up the app from the Application folder and keep that shortcut in the Taskbar. See if the new shortcut works once you close the app and relaunch it.

I just put the unsigned app outside of /Applications and it ran.. So it seems in my case the just locked any unsigned app installing in /Applications folder
