Hello I have had my macbook since the end of november and to begin with i couldn't use it very much because I was busy with work. i have now started using it a lot over the last 2 weeks and something doesn't seem right. First i created a windows 8 virtual machine in vmware fusion and a few days later the machine was in my library but the files on the hard drive had disappeared! I have no recollection of deleting the files and the missing link in fusion makes me suspicious. Then the other day I was just installing some apps from the app store and suddenly the macbook switched off and said something like " your computer restarted because of a problem" mac equivalent of BSOD. Last night i was using the machine and iPhoto crashed accessing iCloud. This morning i have switched on the machine and it said something like your computer was restarted because of a problem (popup error) I have also noticed that when i browse the local hard drive sometimes there are delays opening folders in finder - Like i'm waiting for the drive to spin up - but this is an SSD! Going to phone applecare later and see what they say but not very pleased.
Putting windows on it must have upset it I also had an odd one on my 2013 rMBP it wiped all my saved files in traktor & all my playlists, I now have to create all my playlists again
Apple are very kindly swapping the macbook since I tried a format/reinstall and the issues still persist. Long delays browsing the HDD ! They wanted to setup a repair at Genius bar but I pointed out that we're only 7 days past the holiday return policy so they are doing a swap. I get the new Macbook friday hopefully
VMware fusion 6.0.2 can cause kernel panics. I had it crash once on my late 2013 13" rMBP and the late 2013 15" also. Only happened once on each machine. I googled and saw someone else also had this issue. If you look att he panic log it should refer to Fusion as the culprit.
