I just installed Xcode 5.1 and the latest round of updates. I followed that with a Repair Disk Permissions. For some reason, Apple installs its software with broken permissions.
I then ran Repair Disk Permissions (Applications → Utilities → Disk Utility):
Now, XQuartz will not start:
In the above, Xquartz cannot write to
/tmp after the permission repair because Repair Disk Permissions remove
w from the link.
It appears the permissions in Disk Utility are broken out of the box, too. How does one modify the permission used by Disk Utility so that the utility will not break an installation? Is there a plist somewhere that can be tweaked?
I've been suffering these types of problems for years. Its like a death from 10,000 cuts. Why does Apple not test their software before unleashing it on unsuspecting users?
