MATLAB 2022b .m files stopped opening on MacOS

When I try to open any .m, I just get a blank screen on the editor. But very interestingly, I can still open and edit .mlx files. I tried restarting MATLAB and my laptop, but that didn't help either :(

I'm on a MacOS Monterey with MATLAB 2022b.

Hi Shamoil,

1. Are you trying to open the .m file as a live script?

In that case, save .m as a UTF-8 format, or save it as a live script code(.MLX).

2. Or are you connecting to MATLAB via remote desktop applications? In that case, try starting MATLAB using the "-cefdisablegpu" flag from your system command prompt:

matlab -cefdisablegpu

3. Another thing you can try is to update your graphics driver and see if that resolves the issue.

4. Or start MATLAB using the”-softwareopengl” flag from your system command prompt:

matlab -softwareopengl

5. If the above does not help, you can try to restore the default path and rehash toolbox cache as explained here:

Hope this helps!
