If you’re like me, you rely on Satimage to extend AppleScript, but with the upcoming macOS 27 eliminating Intel-based apps, that will no longer be an option.
With that in mind, I created a Satimage clone that replicates most of its functionality in a background ARM app. Your scripts should only have to change their use line from use application "SatimageOSAX" to use application "MTC_OSAX".
But more than that, this project also adds features and fixes stuff that wasn’t working in Satimage. You can get all the details from the README of this open-source project.
