If you you are missing VSTs after you installed Reason 12.6 or later on your Apple Silicon (M1/M2/M3) Mac, please check the following:
- Check with the VST manufacturer and ensure that the VSTs are natively compatible with Apple Silicon. Download and install newer VST versions if required.
- If the VSTs aren't available in native Apple Silicon versions you could run Reason 12.6 or later in Rosetta mode. Shut down Reason 12/13, right click the Reason 12/13 app icon in Finder and tick the "Open using Rosetta" box. Then launch Reason 12/13.
