Accessing files on external drives on Mac (MacOS Permissions)

The Open command in Synfig on my Mac M1 only allows me to see folders and files on my main HDD.
How can I set things so it can also see external drives, so I can save and open files from there?

Hi and welcome here,

I don’t think that it has anything to do with Synfig, but with the system of permissions of MacOS.

See here : Can't access files on my external hard dr… - Apple Community
Try to select Files and Folders, then Full Disk Access only if it doesn’t work

Please try and report

Any news?
