SFREP software is Windows-only, meaning it cannot run natively on an Apple computer running macOS.
However, if you have installed Windows on your Apple computer using Boot Camp or if you are running Windows in a virtual environment such as Parallels, you can install Appraise-It Classic or Appraise-It Pro there.
Appraise-It Pro v2.8 and up is well supported in Parellels on newer Apple Silicon (i.e. M-class proccessors) computers.
If your computer runs a supported version of Windows, the Appraise-It Pro suite is good to go!
