Sublime Text 4180 and 4200 crash on launch on my m1 max macbook pro running macOS 26.3.1.
I tried renaming the “~/Library/Application Support/Sublime Text” folder to something else so it couldn’t be found, and also deleting the “~/Library/Preferences/com.sublimetext.4.plist” but the program still crashes on launch.
Any ideas?
Does it happen in safe mode? You can get logs by running Sublime\ Text.app/Contents/MacOS/sublime_text --multiinstance --debug from a terminal.
Nope, it doesn’t run in safe mode. Here is the output with username / machinename replacing my details:

Unable to init shm: Failed to create semaphore
(base) username@machinename ~ %That looks to me like either there’s too many semaphores or too much shared memory on your system. Rebooting would likely fix the issue. Did this suddenly start happening or have you been using Sublime Text for a while?
