Hi all, I added an SSD and installed Mavericks, but also kept an old HDD in my laptop with a copy of Snow Leopard so that I could dual boot back into it if I ran into compatibility issues. Of course, this meant I was seeing a lot of duplicate apps in spotlight and in the "open with" context menu. I've been able to fix most problems by doing the following: 1. Adding my old HDD > Applications folder to the exclude list for spotlight 2. Deleting my old com.apple.LaunchServices.plist file to have it rebuilt Now, spotlight is actually clear in mavericks which is good news. However, I'm still seeing Apple specific duplicate apps in my open with context, particularly TextEdit and Archive Utility. I ended up just deleting the version of TextEdit from my HDD, but can't find the Archive Utility (and others) like I did here. I'm having similar problems with VLC and other apps that still live on the HDD. Despite telling spotlight to ignore them and clearing the plist, they still show up. Any suggestions on how to clear up the Open With context menu? Normally I wouldn't care much but it's slow because the HDD has to spin up, sort of negating the speed of the SSD.
