Can't disable Metal Performance HUD

I wanted to enable Metal Performance HUD on my Mac previously as I learned about it and followed a few janky tutorials that ended in me giving up. I put in another couple of hours and managed to enable it globally.


Now I'm trying to figure out what exactly I did to enable it "permanently" and I cannot seem to disable it.


Things I have tried so far:

  1. /bin/launchctl setenv MTL_HUD_ENABLED 0
  2. /bin/launchctl unsetenv MTL_HUD_ENABLED
  3. Mix of the above 1 & 2 and restarting my Mac
  4. Attempting to disable Metal Performance HUD individually for Metal apps

MacBook Air 13″, macOS 13.5

Solved: Used the following code to disable "defaults write -g MetalForceHudEnabled -bool NO"



I have a similar issue with the added issue that Zoom crashes whenever I open it due to the Metal Performance HUD.


Replicable by

  1. Enable Metal Performance HUD globally
  2. Join zoom meeting
  3. turn on video in zoom
  4. Metal Performance HUD is automatically enabled
  5. Another person joins the meeting
  6. Zoom crashes


Using the Fn + Shift + F9 shortcut to disable the HUD works if no other participants are present. As soon as any other participant joins, or I join a meeting with participants already present, Zoom crashes before I can enter the shortcut.


I have tried to disable using the below commands

launchctl setenv MTL_HUD_ENABLED NO

launchctl setenv MTL_Hud_ENABLED NO

launchctl unsetenv MTL_HUD_ENABLED

launchctl unsetenv MTL_HUD_ENABLED 1

launchctl setenv MTL_HUD_ENABLED 0

launchctl unsetenv MTL_HUD_ENABLED 0

launchctl unsetenv MTL_HUD_ENABLED NO

launchctl setenv MTL_HUD_DISABLED 1

launchctl unsetenv MTL_HUD_DISABLED 1
