Hi there,
so in my slightly OCD world where everything is nicely organised I
like to use the Repair permissions function quite regularly. Not sure if this is good
practice but it seems to me if there's a repair button and it finds thing to do then why
not? As an experiment (probably to appease my raging OCD) I hit the repair button again
after repairing permissions once to see what happen and sure enough a whole load more were
found. My question is thus: How come it doesn't Repair all the Permissions at once and how
many times would I have to hit Repair before there were no more Permissions to Repair?
(patience my precious OCD). And more to the point just what are these Permissions
anyhow?!
Any ideas out there?
Many thanks in advance,
Beardy.

Firstly.. There are people that believe that repairing permissions is of no benefit. My
experience definitely suggests otherwise. So you are not wrong to repair them once in a
while. And even "if" it didn't help, it certainly doesn't hurt.
Also, there are
things the repair process points out, but does not actually fix. Either because it can't,
or it doesn't need to. So no matter how many times you repair, they will still be there.
You'll likely find the same things appear on the repair process on anyone elses computer
with the same OS too. It's nothing to worry about.

It is often where a file's permissions have been manually changed for whatever reason. The
OS quite correctly assumes that you don't want it to automatically change it back to what
it was.
It might be for some other reason though, either way I wouldn't lose
any sleep over it.

There could be "more" permissions to repair because of where you
initiated the repair permissions from. If you use the Disk Utility from your startup
drive, then there are a number of permissions you won't be able to repair. It's always
best to repair permissions from the install DVD.
I hate to say it, but if one
has to ask what these permissions are for, then it's probably a good thing they are there
at the very least to protect the system from "newbie" attempts to alter it. Hackers are
obviously a different case altogether.

I don't believe
this is true, and I think there are scenarios where it can actually be harmful. For
example if your install DVD is 10.5.0 and you have 10.5.8 installed then I believe using
the install DVD's Disk Utility might actually reset permissions wrongly as it's working to
an out of date "map" - by contrast the system Disk Utility app will at least be up to
date. That's my limited understanding anyway - it boils down to my having been advised to
NEVER use the install DVD in this fashion unless the installer system version number is
the same as the installed version.

Not true at all. The Disk Utility on the DVD and the only in the hard drive rarely change.
Despite the updates in the OS, rarely are any new frameworks added (most times they are
updated). Permissions are set based on what's in the Receipt's folders (and BOM packages)
and not on the app itself.
Using the Disk Utility from the DVD is recommended
to clean up your hard drive.

I seem to remember Apple dropped that
recommendation, starting with the introduction of Tiger.

You have a tech-note to back that up? All my experiences to date indicate otherwise.

Yeah, that's what I remember too, for the very reasons mentioned.
