OSx newbie need help

Hi guys.

I've install Lion and all looks OK.

The problem that puzzle me is that when ever I go to "Get Info" about any file or folder to see permissions there are users: system; wheel; everyone; but not my user name. I do get the system and everyone but what is user wheel I've no clue. On some folders and files I'm able to add my user name to some I'm not. What's wrong here??

Second question : is there any program that'd help me to clean

install kexts that are not needed, I did try install couple for video, network e.t.c that did not work before I find working ones.


Thanks for any help and info.


This is my system:

MB= ASUS P5QL Pro;BiOs AMI (08/26/08)

CPU= Pentium®Dual Core E5200@2,5Ghz

Mem= 4Gb (2x 1Gb DDR2-533 SDRAM + 2Gb DDR2-667)

Graphics= MSI nVidia GeForce 9400GT (1024Mb)

Audio= RealTek ALC888/S/T @Intel 82801JB ICH10-HD controller

Network= Atheros AR8121/AR8113/AR8114 PCI-E controller

Seagate ST3500630NS(empty)

OK, so I found the answer for the "wheel" user, apparently it belongs to the system somehow from long distant past and Lion is not showing system folders the same way as SnowLeopard. Since I don't know OSx much there is a lot for me to learn.

I found about this when I installed MacKeeper IS and it was giving me error about helper task and wrong permissions, the support guy told me to change permissions to "read & write" for all users and the error is gone. That is how I found that there is "wheel" user. Guess I just leave it there and forget about it.


Well, what about the kexts cleaning is there anything I have to do, or just leave it as it is, the system is working why fix it.
