This is very interesting. I’m not on latest macOS but I should check on my wife’s machine. So, it seems like in newer versions of macOS, Apple has gone down the same route as Windows, to combat ransomware, and has started to prevent “non-authorized” apps from having write-access to the Documents directory and its sub-directories.
I wonder what apps are automatically authorized to write to Documents, maybe when they’re from the app store? But at least it seems like VCV Rack is not automatically permitted.
It would be great if @Vortico could investigate the possibility of including the authorization in the Rack installer, because this has bitten a lot of people now. Also, if there are any real macOS wizzards in here, on new versions of macOS, it would be great if they could come up with the short and sweet command-line incantation to grant this permission, and share it here so people can do it easily.
Yes, because it’s just a temporary hack. The solution is as written above, to grant Rack permanent write permission, like written: Settings => Privacy & Security => Files & Folders, and then grant access to VCV Rack. And even better would be for that to be included in the Rack installer, so people don’t have to go through that frustration in the first place. Just remember to blame Apple, because they’re the ones that did it.
