Apple Silicon only. FramePal cannot run on an Intel Mac — there is no fallback, and it
will simply not open rather than telling you why. Check Apple menu → About This Mac: if it
says Apple M1 or later, you're fine.
After it downloads
Open the disk image and drag FramePal to Applications.
Launch it once. It installs its own Premiere extension — no admin password, nothing to drag anywhere.
Restart Premiere Pro, then open Window → Extensions → FramePal.
Paste the activation key from your email. That's the whole setup — no API keys, no Terminal.
