Why is MATLAB crashing on Mac 10.15.7 or later when I interact with or mouse over figure content?

I recently installed an Apple security update 2021-007 for MacOS 10.15.7 or later.  Now, when I interact with certain figures using my mouse, I get a MATLAB crash.  The crash log includes lines with "glReadPixels", "gpumInitializeIOData.cold.1", "gpumCreateComputeContext", "gpusKillClientExt", and/or "AppleIntelHD4000GraphicsGLDriver". I see similar crashes when using other software such as Firefox, Safari, and my VPN client.

This is a bug originating in the Apple security update.  It affects users with the Intel HD4000 graphics driver.  To confirm that you are seeing this bug, execute the following command in the Mac terminal immediately after the crash occurs.

log show --debug --info --last 5m | grep IOA

If the output looks like the following, particularly with the 0xfffffffb error code, then the crash is related to this known bug.

For most situations, upgrading to MATLAB R2021b should solve the issue.  If you are still encountering this issue in MATLAB R2021b, or you are seeing a different error code when you run the steps above, please contact MathWorks Technical Support .
