when opening image library i see spinning wheel like it tries to index something or so.
i had to restart GS completely to make image library work again. and it will fail again in several minutes.
In the Photos preferences > iCloud is the option “Optimze Image Storage” activated maybe?
(If so, the GarageSale Media Browser might not be able to access the Photos library.)
This looks like an issue with the Sandbox system to me, where for some reason GarageSale cannot access to folder with the pictures outside it’s sandbox, even though you specifically gave it permission to do so.
If I recall correctly, wasn’t GarageSale 7 unable to import the GarageSale 6 library on your Mac, too?
i do not exactly remember about importing GS6 library. but currently this problem started to happen not so long time ago. i believe from previous version of GS.
