The latest version of AppleGlot at time of writing is 4.0 (v161.6), and its installer has the following issues on macOS Catalina and Big Sur:
- the signing certificate is invalid (FB8770951)
- it hasn’t been updated to work on macOS Catalina’s Read-Only System Volume (FB8773764)
This repo contains a bash script to successfully install AppleGlot on macOS Catalina and Big Sur by placing its libraries in a writeable location and patching the appleglot binary to use these libraries – more information is available in this blog post here.
