I confirmed that the binary attached to 1.9.9 release is a universal binary:

/Users/velvetbaldmime/Downloads/sbtn-universal-apple-darwin: Mach-O universal binary with 2 architectures: [x86_64:Mach-O 64-bit executable x86_64] [arm64]
/Users/velvetbaldmime/Downloads/sbtn-universal-apple-darwin (for architecture x86_64):  Mach-O 64-bit executable x86_64
/Users/velvetbaldmime/Downloads/sbtn-universal-apple-darwin (for architecture arm64):   Mach-O 64-bit executable arm64

and after chmoding it and removing the quarantine attribute it launches SBT:

~/p/n/proompts (refactor) > xattr -d com.apple.quarantine ~/Downloads/sbtn-universal-apple-darwin
~/p/n/proompts (refactor) > ~/Downloads/sbtn-universal-apple-darwin

The GITHUB_TOKEN we were using in the Cirrus CI job is expiring in a couple of days. I guess we don’t need it anymore, right? Should we also remove that script, then?
