Specifically, after backing up needed data, I wiped my drive and installed Yosemite via a USB stick that installed a Yosemite installer onto. #2 - 2015-11-02 01:00 PM - Alexander Salveson Nossum Experienced the same issue. Reinstalled PROJ from [1].

Try to reinstall some additional frameworks as suggested before. Other possible cause, if the first suggestion fails is some misplaced or bad installed item into this folder: "/Users/your user name/.qgis2". This is an invisible folder. To access it, try to open a window, do CMD+SHIFT+G and paste this line with your correct user name: /Users/your user name/.qgis2 2021-01-29 1/2
