First of all I notice you have a lot of applications running. I’d recommend quitting them before trying to run GW2, they’re using up resources that the game probably needs.
I would suggest opening Finder and navigating to your user folder>>Hold down Alt/Option and click Go in your menu bar>>Library(it will only show if you hold alt)>> Application Support>>In here there should be a folder called Guild Wars 2, make a copy of it on your desktop, just in case, and then delete it from the folder.
Try running GW2 again and hopefully it will try and rebuild this folder. Potentially solving your issue.
(I realise your mac isn’t in English, so the Go option in the menu bar might not be called Go? but you’ll have to figure that out yourself xD).
Let me know if this helped at all!
This worked for me! Thanks a lot!!!
