Downloaded Logos 4 Mac to my Macbook two days ago. After initial download and then indexing for about 7 hours, it proceeded to alternate between downloading updates and indexing for another 20 hours or so. It never indexed all the way. I finally quit late last night to give my computer a break after about 32 hours of this. I didn't experience this long of a process on the PC side via Parallels last year. Any thoughts?
