Well like most everyone should have drives connected to their Mac and occasionally the "Open With" will have all the versions of software that I have on other drives (cloned drive). Well I have come across a /Applications/Utilities/Terminal command that will fix that. Just open Terminal and copy the command Code: /System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -r -domain local -domain system -domain user and let it run. This will reset the right click's "Open With" list to only show application on that one Mac. Just let it run (for about 15 second) until it gives you another prompt. It really works!
