So, finally got my hands on my new rMBP (15" base model) earlier this week. Was able to download a few updates - incl Mavericks 10.9.1, Keynote, Numbers, Pages, etc. Here's something I noticed - After downloading/updating iPhoto and iMovie, the older version of iMovie (9.0.9) is stored in a file on the Hard Disk (happened to notice while browsing via Finder). Is this the same with everyone? I am yet to update Garageband - just wanted to ask if updating will keep the older version as has been the case with iMovie. Funnily, iPhoto's older version was not saved. PS: Still getting my head around the new environment (switching from WinXP). Any advice on "must have" apps would help. Thanks!
