Mac OS X 10.4.5 Special Report: (Intel-specific): Duplicate "Open With" items

Some users have reported duplicate "Open With" items after updating to the Intel version of Mac OS X 10.4.5.

There are a couple fixes for this issue, previously noted on MacFixIt.

A Terminal-based fix, involves use of the lsregister command, which can be invoked to perform general maintenance of Launch Services, working to eliminate duplicate applications and other system issues.

We also have a tutorial called "Deleting old copies of applications (documents opening with the wrong version, program)" that offers several fixes for this issue.
