Hello! Hmm... What kind of error do you see? May we ask what your OS is? (ex: OS X10.5, 10.9, etc...)
Well that's weird... it actually opened this time. It was showing something like "application cannot be opened" with the finder logo. I've got version 10.15.7. I have no clue why it opened this time but thanks for responding anyway lmao.
Don't have a Mac to try it out on, but good to hear it worked!
