Lost access to Macintosh HD. -- I had gone into permissions and set user EVERYONE to no access -- at first this was blocked out...
BUT i being resourceful went and accessed the Macintosh HD by selecting "get Info" under permissions from THIS window I was able to click and the user EVERYONE and clicked on "no Access" -- at that point the FINDER for this operation locked up... I was forced quit. and REBOOTED.
NOW>>>> my system sits with the Apple icon and an ETERNAL bootup process going no where. I have looked for threads on what to do..including what seemed to be the answer or close to it here.
After following the instructions for rebooting in Single User mode..
I ran /sbin/fsck -fy After running this twice...I get a readout that says " The Volume Macintosh HD appears to be OK"
As ADDITIONAL issue: I cant eject my CD...to boot from Emergency CD/DVD. My system is an IMAC (purchased in 2010) OS is Snow Leopard.
Please help me to either
1. Repair permissions from single USER bootup mode....for Macintosh HD
2. REboot from System Startup Disk.. (need to eject existing CD first!) --and then repair permissions that way
