UPDATE: I'm not exactly sure what I did, but I did a Shut Down and a message popped up that said I had some updates to install. When I logged in, I was running 10.7.4! Problem solved? I recently installed a third party SSD in my MacBook (not sure if that would affect this). So I used Lion Recovery Disk Assistant off of a flash drive and brought it up to 10.7.3. I noticed that the 10.7.4 update doesn't even show up in Software Update. So I download both the client and combo update, and neither will let me update! It says, "Mac OS X Update Combined can't be installed on this disk. This volume does not meet the requirements for this update." I was thinking it may have been because of the SSD I just installed, but I'm not sure. Does anyone have any suggestions?
