is Repairing Permissions just superstition now, dead-chicken-waving?

Like, after an OS upgrade, or after installing Adobe CS?

[support.apple.com]

Files that aren't installed as part of an Apple-originated installer package are not listed in a receipt and therefore are not checked. For example, if you install an application using a non-Apple installer application, or by copying it from a disk image, network volume, or other disk instead of installing it via Installer, a receipt file isn't created. This is expected. Some applications are designed to be installed in one of those ways.

Also, certain files whose permissions can be changed during normal usage without affecting their function are intentionally not checked.

its like rebuilding the desktop

sometimes it fixes things but most of the time it just makes me feel better.

When duplicating an external drive to a new computer's internal drive, a permission fix is defiantly required. Moves like a snail until you do...

Don't you think that if there was no point to it Apple would have deleted the function? They already take away things from the OS that are useful to many users, I doubt that they have left permission repairs due to an oversight.

Most of the time, yes. Voodoo.

If you see a bunch of errors that some app can't write a temp file or a printer queue can't be created or you're poking through your crash logs and find a "permission denied" error on a file in the System/Library folder then it might help.

But when was the last time you encountered one of those errors?

No.

In fact, after an OS upgrade is the second-least likely time that you'd need to repair permissions. (Ranked second after an OS install.) The Apple installer checks permissions on every file/folder that it installs.

Adobe software often does have problems with permissions on certain folders, but since those permissions errors are almost always on folders in a user's Home folder, repairing permissions with the DU would do nothing at all to fix those problems.

What are permissions and their purpose?

Read just the section of the article that this link jumps to:

I probably haven't run RP since 10.3 or 10.4.

Repair Permission sare not superstitious because they repair OS X system-related objects and Apple-provided applications when damaged.
