[cura 4.8 compatibility mode issue osx]

Hi,

 

apologies if this is a known issue, i could not find any solution online.

 

cura has suddenly stopped showing simulation view, instead it is in compatibility mode. i have checked the log and it is seeing opengl 2.1. 

i have been running cura on this machine without changes to either cura or osx for about nine months. simulation view worked perfectly until last week. i have tried fresh installs of cura including all versions from 4.0 to 4.9. i have updated osx to the most recent my macbook can run. 

while searching for the issue i have seen that there are issues about apple not supporting opengl etc, but this was all running perfectly until recently.

 

does anyone have any idea why cura would suddenly force compatibility mode (unticked in preferences) or why osx would suddenly show an older version of opengl?

i know thats ancient, but it was fine last week.
