The previous download file for the mac was named "unguided-applesillicon+intel64.app.rar" which when extracted would be named "unguided-applesillicon+intel64.app" which mac would then think contained the actual .app contents but it just had the actual .app folder inside it. So, the new download file is named  "unguided-applesillicon+intel64.rar" which will become a folder named "unguided-applesillicon+intel64" containing the actual .app folder when extracted and shouldnt cause issues (i think).
