Matlab 2020b won't open on Mac OS Big Sur
123 views (last 30 days)
I've recently updated to Matlab 2020b, which has worked fine for a number of weeks. I have updated my Mac OS to Big Sur this weekend, and Matlab 2020b now won't open (not excluding the possiblity that this could be a coincidence).
The icon appears for a second or so, as if it is loading up, and then disappears. I have tried restarting my computer, reinstalling Matlab, and reinstalling Java (following suggesitons on previous posts). Any recommnedations would be very welcome!

I just ran into this, and it appears to be a disk access issue (same thing - can't launch from icon but can launch from command line). To fix, go to Preferences>Security & Privacy>Full Disk Acccess, unlock, and click the check box by MATLAB, and it should start launching via the dock icon once more.

I'm also having this problem.
When I originally updated to Big Sur, I was able to get R2021a to open by changing the Full Disk Access settings as Dmitry suggested.
Big Sur automatically updated again last night, and I'm now on version 11.2, and MATLAB won't open this morning. The logo pops up and stays open, but the IDE never presents itself. The disk privileges fix that worked last time doesn't work anymore. I can't even open R2021a from the command line with sudo privileges by typing:
Is there a permanent fix for this? I've honeslty found Big Sur extremely buggy. Have others had a similar experience with the updated OS?

If you are connected to an external monitor, try unplugging it, opening up MATLAB with your laptop screen open, then plugging monitor back in.
This solved it for me and it appears MATLAB is still struggling with some screen-level events on macOS.
I hope this will help someone in the future!

I found this problem relates to the ATS.Framework on Mac OS. I was unable open matlab on Monterey using the -desktop option.
I fix this by following this thread.
Hope this helps someone for it bothers me for quite a long time
