macOS 10.5-10.14
Also available: macOS 32-bit - 18MB
macOS 10.15+
REAPER v6.36 - 15MB
macOS 10.15+ Catalina/Big Sur (Notarized)
Note: the macOS 10.15+ Catalina/Big Sur macOS download is notarized and uses the "hardened runtime," which may reduce compatibility with certain plug-ins. You may still run the regular 64-bit macOS download on Catalina and Big Sur; however, you must shift+right click and choose "Open" when running that version for the first time.
For maximum Intel plug-in compatibility, users with M1-powered Macs should use the Intel (10.15+) version rather than the native ARM64 beta version.
