Hi all. So I'm running Mac 10.14.6, and I've been using the Jan 12 2020 Sheepshaver with no problems. I recently saw the March 15 update and decided to try that out.

Got this error on attempting to launch it:


I'm aware that the ROM file is not in the folder in that picture; it gives the same error message whether the file is there or not. I'm fine using the Jan 12 version for myself, but I was hoping to help get a friend set up, and he runs 10.15 so I figured it would be best if I gave him the latest version.

Anyone have any ideas?

Oops! Resolved now. Somehow, my Security preferences for "Allow apps downloaded from" had reverted to just "App Store" instead of "App Store and identified developers." I switched it back and all is well again. Rookie mistake!

Does right-clicking and selecting Open work even when security preferences are "App Store only?"
