Let me try to clarify. When running Disk Utility there are two
maintenance functions you can do - Permission Repair and Disk Repair.
The first one can be done on a live booted disk or partition. The second
one can only be done on a partition that isn't being used to boot up a
machine. In the case where you don't have a recovery partition and don't
have another drive to boot off of you'll be limited to doing a
permission repair. Even then, I suspect it can't repair as much because
many files are in use. The better way is to boot off another drive,
partition, thumbdrive or recovery partition and then do the permission
repair. This also allows you to do a disk repair.
Hope this helps clear up when you can use the two very similar named
functions.

Wait, now I'm even more confused. First, it seems like you're saying
you can do it, but you're not sure to what extent. Now, look at the
second part of what you say. Then, you said, you can't do it on the
running system. So, I'm confused. Which is it? Can you, or not?
LOL!
Sorry for the confusion.

permissions
If the OS is up and running you can run disk utility and do a disk
permission repair on the running system. Not sure if it is able to
fix as many things as when booted from another system but you do
have the option. You can't do a disk repair on the currently
running system.

Guys,
Hopefully one of you all can explain this to me.
First off, I'm not saying anyone is being untruthful. It's very
very! likely that I may just not be understanding things
entirely. I don't clame to be perfect.
I have a friend who will be left unnamed who has a mac system
running Snowleopard. NO, it's not the guy on this list
ironically. Anyway, they had to recently repair disk permissions
on their main internal Macintosh HD. They can't upgrade to
Yosemite, as their system won't support it. Anyway, they have
misplaced the Snowleopard DVD which came with their system.
Further, they don't have any other bootable partition internally
nor externally. So here lies my question.
How in the world were they able without the SL DVD media or
another bootable partition to repair permissions on their main
primary macintosh HD volume?
Here's the thing. From what I remember, correct me if I'm wrong,
Snowleopard didn't have a recovery partition, did it? Normally,
after Lion and higher, you could just boot, and hold down
command+R to go to recovery. From here, you could run Disk
Utility, and repair permissions. That's not going to work though
in SL, as there's no recovery that I recall, hince why you got a
physical DVD back in the days.
You can't exactly repair permissions though while booted into the
OS though, as certain files and folders will be in use, and the
volume will be locked, therefore not allowing a repair to be
done. So, with no media, and no external bootable partition, and
no recovery partition, how in the world is he/she doing this?
Either something's not adding up here, or I'm just thoroughly
confused, and my guess is, probably the ladder. Just curious
what on earth I'm missing here. Enlighten me.
Chris.
