FIX: Quick look on OSX not working (black box)

I’ve recently replaced the hard drive in my MacBook Pro with a higher capacity one (write up to follow).  After restoring from time machine I found that quick look no longer works.  If you try to quick look a file (select file, press space bar) you just get a black box.  If however you select two files, hit the space bar, then click on the index sheet button (little button with 4 windows in a 2×2 stack), quick look seems to work – but only in the index sheet.

This is a common problem, but took some forum trauling to find a solution, so i’ll save you the work.

Simply reinstall the Mac OS X v10.6.2. Update.  I was running 10.6.2 already, and it simply reinstalled over the top.

If this doesn’t fix the problem, boot your MacBook from the install DVD, select Utilities > Disk Utility, and “Repair Disk Permissions” – you’ll have to boot from the install media if you are repairing the same drive that your system boots from.

Good luck – post a comment and let me know if this works for you.  You could always talk to me on twitter too :)
