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
Tried all of the following to no avail:
1. holding spacebar until CD ejects
2. holding left mouse button until CD ejects
4. Eject button on keyboard
Do you know how to fix this from UNIX commands from Single User Bootup?
Yes Im sure it restarted
This was in my initial post Snow Leopard 10.6x--Sorry I didnt say the exact version....
The grey progress bar appeared... upon holding the SHIFT on REBOOT
How long can I expect this to take...beore I concluded its not working?
over 2 hrs and no sign of life...
honestly...I dont think this is working...
Did you read the forum thread that I posted?
Can we fix this in Single User Bootup mode?
unable to eject disc..unable to effect a fix to permissions...so far
Sorry I am in CT USA it was late. Yes I read your post this usually won't work in Single User mode which is why I am trying to get your disk out:/sbin/fsck -yf/sbin/mount -uw //sbin/autodiskmount -va/usr/sbin/diskutil repairPermissions /Before you try that... try this, below, then reboot and try those methods to get your disk out, trying the repair from your boot disk is more likely to work:Resetting the SMC & PRAM for Mac Pro, Intel-based iMac, Intel-based Mac mini, or Intel-based Xserve 1. Shut down the computer. 2. Unplug the computer's power cord. 3. Wait fifteen seconds. 4. Attach the computer's power cord. 5. Wait five seconds, then press the power button to turn on the computer. 6. Press and hold the Command-Option-P-R keys before the gray screen appears. 7. Hold the keys down until the computer restarts. 8. Release the keys.
Yes I did that already... from the Bootup Disk.
I did the following from Disk Utilty
1. Fixed permissions
2. Verified HArd Drive..
3. Repaired harddrive
