Hello all,

I saw that I'm a few versions behind the latest build, so figured I would download the latest release of gam7 and drop it into my bin folder. However, when I try to run it, macOS claims the file(s) can't be verified and refuses to run it. I went to the system settings and approved the binary, but it's also showing the same error on the seemingly endless list of library files GAM depends on it. I tried going through them for a bit, but there really are an insane amount.

Am I doing something wrong? Shouldn't GAM and its dependencies be signed?

Which MacOS version are you running?

What version of GAM exactly are you trying to install?

I'm running macOs 26.3. I was using GAM version 7.25.01 originally. I saw on GitHub there's many patches since, so I downloaded the macOs 26.3 ARM release, and just replaced the files in my GAM's bin folder with those. Maybe that's a bad way of doing it, but I didn't immediately see mention of a more official method of upgrading the bins in place.

The correct method to upgrade on MacOS is to run:

bash <(curl -s -S -L https://gam-shortn.appspot.com/gam-install) -l

thanks, I did see that finally, after borking everything. For what its worth resolved this otherwise with the team, and if you do download the package directly from github and copy it in, you can also run "xattr -dr com.apple.quarantine /path/to/gam" and that will let it work
