yes, it is reproducible. no reboot help

the original message is exactly that command (but the formatting broke the output)

❯ ls -l /private/var/run/com.apple.security.cryptexd/mnt/ ls: /private/var/run/com.apple.security.cryptexd/mnt/: Permission denied

unfortunately that is not helping. ~ ❯ sudo chmod +r /var/run/com.apple.security.cryptexd/mnt/ ~ ❯ ls -al /var/run/com.apple.security.cryptexd/mnt/ ls: /var/run/com.apple.security.cryptexd/mnt/: Permission denied ~ ❯ cd /var/run/com.apple.security.cryptexd cd: permission denied: /var/run/com.apple.security.cryptexd ~ ❯ sudo chmod +r /var/run/com.apple.security.cryptexd ~ ❯ cd /var/run/com.apple.security.cryptexd cd: permission denied: /var/run/com.apple.security.cryptexd

I tried that, unfirtunatly that did not change a thing here ~ ❯ sudo chmod o+rx /var/ ~ ❯ sudo chmod o+rx /var/run/ ~ ❯ sudo chmod o+rx /var/run/com.apple.security.cryptexd/ ~ ❯ sudo chmod o+rx /var/run/com.apple.security.cryptexd/mnt/ ~ ❯ cd /var/run/com.apple.security.cryptexd cd: permission denied: /var/run/com.apple.security.cryptexd

~ ❯ ls -alR /var/run/com.apple.security.cryptexd/ total 0 ls: /var/run/com.apple.security.cryptexd/: Permission denied I could change the permissions to "g+rx", but that group access is reset on system restart and does not persist

I re-installed macOS 26. RE-INSTALLED it, in case that is something with permissions. Only to face the very same bug with Xcode 26.2 I don't know what, why, and how, but this problem has no reasonable solution [object Object]

The Xcode 26.4 beta 2 seems to address the problem. A side effect it made the Xcode 26.3 unable to find metal toolchain at all - least the current workaround stopped working.
