Error: mdworker lsboxd deny mach-lookup

I also had these issues with my 10.8.2 iMac

However, safe boot would not work for me, when i rebooted to go into safe mode it would start the progress bar, but stubbornly stop at about 20-25% of the way through.

I left it like this for 2 days, but still it would not progress.

So, to resolve this, i downloaded mountain lion onto a fresh USB stick ( instructions elsewhere ) and then did a full clean install.

I reformatted the primary hard drive.

Did a clean install of mountain lion.

and then did a full time machine restore ( as part of the mountain lion install )

After all that, i was able to safe boot cleanly in normal time, which i did once or twice.

At this point the system is fully recovered, no lsboxd errors, and overall it seems snappier, as it looks like spotlight in particular is working in a cleaner environment.

Prior to this i had done the upgrade ( i.e. not a clean install ) for both lion and subsequently mountain lion.

Hope this helps.

You can modify the /System/Library/Sandbox/Profiles/system.sb file to allow lsboxd and coresymbolicationd to get rid of errors. Make a backup of system.sb first, then add this to end of system.sb file and reboot your system:

;;; MDWorker Fix

(allow mach-lookup

(global-name "com.apple.ls.boxd")

(local-name "com.apple.ls.boxd")

(global-name "com.apple.coresymbolicationd")

(local-name "com.apple.coresymbolicationd"))

Yup, SAFE START AND THEN REBOOT Worked for me too! Thanks!!! Safari is snappy now!@!

I'm going to try this and report back. The safe boot doesn't work for me. Can someone explain what the safe mode trick does to fix this problem?
