tech_guy Posted February 4, 2015 Posted February 4, 2015 Not having a good day. An enterprising member of staff has attempted to reset the perms on the HDD in their iMAC which is running 10.6.8. Don't ask me why. The machine had a hissy fit apparently, they restarted it, and now it doesn't boot. Wonderful. I've used Single User Mode and run fsck -fy which states that the file system was modified and a subsequent repeat says all is good, but the machine will still not boot. In verbose mode it just sits at Waiting for DSMOS... Given what it went through I guess I need to reset all the permissions? A quick Google turns up some helpful stuff but our web filter classifies all the sites as web chat so I cant see them. And I left my smartphone at home today. Help much appreciated!
3s-gtech Posted February 4, 2015 Posted February 4, 2015 Can you run Disk Utility from within Single User Mode? That can go through and repair them, or at least try. Worth a shot.
mac_shinobi Posted February 4, 2015 Posted February 4, 2015 Boot off a snow leopard installer disc and run disk utility and repair disk perms that way or make a bootable snow leopard drive and do it that way ( again not re installing the os but just to use disk utility to repair disk permissions ) If it still wont boot then backup data as required and re install OS X completely from fresh
3s-gtech Posted February 4, 2015 Posted February 4, 2015 Of course - SL doesn't have the advanced startup options of the later versions built in.
Arthur Posted February 4, 2015 Posted February 4, 2015 Boot off a snow leopard installer disc and run disk utility and repair disk perms How effective would that be though? http://support.apple.com/en-gb/HT201560 Does Disk Utility check permissions on all files? Files that aren't installed as part of an Apple-originated installer package are not listed in a receipt and therefore are not checked. 2

davidacland Posted February 5, 2015 Posted February 5, 2015 You could try single user mode and: mount -uw / # To make the boot drive writable diskutil repairPermissions / # To repair the permissions
DMcCoy Posted February 5, 2015 Posted February 5, 2015 (edited) I doubt the repair permissions will work, it's only checking against the bom details for installed applications, it's probably not going to go anywhere near / and /Users. Edit: you can probably make it boot with sufficiently loose permissions and get the files off it, but really a reinstall is the only way to get things back to how they should be Edited February 5, 2015 by DMcCoy

tech_guy Posted February 12, 2015 Author Posted February 12, 2015 Can you install over the top of itself ( repair install ) Yes, thanks, I did just that and everything seems fine now.
