I also posted this bug report on github, I post it here too just in case, delete the extra one.
After testing art on mac os here’s what I found:
_ no worries at the installation (mac os high sierra imac 27 late 2013)
_ the software launches well
_ the software icon is not displayed correctly (art_mac_01.png)
_ I can’t navigate in my photo folders (under the “2020” folder on the screenshot) (art_mac__02.png).
_ I can only navigate in this folder if it is also open in the finder. I can’t go into these sub-folders.
I can only access a folder if it is open in the finder.
_ The lens correction remains grayed out and I can’t choose either lens or case (art_mac_04.png)
_ icons in modules do not appear (art_mac_03.png)
_ the export does not start, even if you check auto start and change folder.
_ there are lines that appear around the menu windows (art_mac_05.png)
Hopefully this will help the porting of this great software to Mac OS X.
