I got a new MBP retina recently. I am having a few niggling issues though, which are irritating me no end. Firstly, having made vlogs on my old Windows PC, I can tell you that Movie Maker is not nice! Its tacky and lacking basic features. Knowing OSX came with iMovie I couldn't wait to use it. Problem #1 is iMovie and Facetime. After recording a video from Facetime from inside iMovie, and attempting to edit it, the Audio goes out of sync. I have tried everything possible to correct it - detaching Audio / Optimising and everything else suggested on Google. Nothing helps. How such an obvious bug is present in iMovie is beyond me. I found posts on this issue dating back to 2011! All of which were unresolved. A good reason for me getting a Mac was access to decent software by default (like iMovie). After an outlay of £1800 I do not relish spending £200 on Final Cut Pro. At this point in time I just plain do not need such advanced video editing software to justify the cost. Problem #2 is that my desktop wallpaper will not save. I set it to a photograph and whenever I reboot its reset to some default wallpaper Problem #3 my mouse (Mighty Mouse) randomly disconnects. It will suddenly stop responding and I have to use to trackpad to go to Bluetooth and find it and Connect. Other than the above, I actually am finding my return to OSX (I had a mac in 2005) quite enjoyable. Being a long time Windows user I did feel a bit like a 'noob' at first but I am finding it much nicer to work with than Windows 8 (yes I had technet and upgraded to the RTM just before I decided to go for a new MacBook instead of another PC ) P.S -- How hot is a MBPr supposed to get? I was looking at some videos online of heat tests and people were getting CPU temps at load of 100 C!!!! That sounds crazy hot. I googled the CPU and its rated up to 105 C which seems rather damn close to failure! Mine gets pretty warm around the F/S keys to the point where its almost uncomfortable to keep my fingers pressed there.
