WD Sync Installer quit unexpectedly

Finally this genius guy found the solution. Apparently the problem is due to a disabled font (Arial) on Mac OS.

WD Sync Installer quit unexpectedly! (Mac OSX El Capitan)

Hi existme, I had the same problem until I saw your “debug dump”. You’re right to question that the problem is due to: The clue was the “withFont:” part, so I checked with Font Book and Arial was OFF. I switched Arial ON and the installer worked immediately! The first window that the installer opens uses… Arial Have a nice day!

Have fun!
