Getting Attract Mode to Work in Catalina
First please note Some of the things I have done may not be necessary, I have put them into chronological order and marked the items that may not need to be done with an * - I don't think it will cause any issues if you do them but you may be better off trying just those that need to be done first and if they do not work go back and perform the actions with an *
1. Download Attract Mode
2. Open the package and when it opens a windows suggesting you copy Attract to Documents, Don't, instead copy it to Applications instead.
3. * Now open System Preferences and click on Security and Privacy, click on the lock in the bottom left the window, insert your password then scroll down to Full Disk Access. Leaving that window open in Finder navigate your way to the Attract App in the applications folder and drag it into the right hand panel of the Privacy and settings windows.
4. * repeat the above but this time navigate to the hidden .attract folder in your users directory - note if when you get here you can't see the folder, its because its hidden, so click Shift, Command and Period (full stop) and the hidden files will appear - and drag that to the same place as before.
5. Make sure none of your Videos, Wheels, Roms, etc, etc are in your user folders i.e.Documents, Attract Mode won't be able to access them so move them somewhere else outside of your users areas or like I did moved them to another volume. repoint your CFG files in attract to correspond to any changes you had to make and hopefully like me it will all work.
NOTE - I WILL PERFORM MUCH MORE TESTING ON THIS OVER THE NEXT FEW DAYS AND IPDATE THE FORUM WITH ANY NEWS GOOD OR BAD.
