Release Note Description

Additional information about the issue reported

I noticed that the ~/Library/Logs/CoreSimulator folder had incorrect permissions on DCI-MAC-BUILD-232 * which prevented the helix-runner user from writing in that folder. Quitting the simulator app, deleting the folder and then running simulator again recreated the folder with correct permissions.

I don't yet know how the system got into this state.

* also on DCI-MAC-BUILD-282, but I couldn't access that machine for some reason

If anyone from dnceng can log in to DCI-MAC-BUILD-282 via KVM please check the folder permissions :)

Looks like it is also happening on dci-mac-build-235
