Repair permissions on multiple drives in one step System
After updating to 10.4.8 today, I restarted and went to repair permissions in Disk Utility. Since I have a second drive that I run SuperDuper! on to make a nightly bootable clone, I was going to run permissions on that drive, too. I h ad never tried this before, but I Command-selected both my bootable drives and then clicked Repair Permissions.

Voila! Both drives were repaired simultaneously.

[robg adds: I think the repairs happen sequentiall, not simultaneously, at least based on my limited testing (I didn't want to actually repair permissions on my development drive). Still, it's a nice timesaver for those who have multiple bootable drives.]

Repair permissions on multiple drives in one step

I *suspect* that when you repair permissions on any drive other than the boot drive, the diskutil command will not use the /Library/Receipt folder on that other drive for the repair. It might not always be a good idea.

Repair permissions on multiple drives in one step

The Repair Disk Permissions function uses the /Library/Receipts directory on the volume being repaired. For more on repairing permissions, see our What You Need To Know article.

As for the hint above, keep in mind that when SuperDuper clones a drive, all permissions are cloned, as well. This means that if you're really concerned about permissions, you can just enable the "Before copy: Repair permissions" option in SuperDuper -- this will repair permissions on the source volume before cloning it, and ensure that both the source and the target volumes have the "correct" permissions after the copy.

Repair permissions on multiple drives in one step

This hint is stupid. It perpetuates this silly "repair permissions after updating your OS" myth and has NO PLACE on a site like this.

Sigh.

I agree. Repairing permissions is not a regular maintenance task. It's generally a waste of time and in some cases will undo permissions that you have set manually.
