I got a second hand macbook pro on tuesday, it is the 13" 2010 model and is two months old. However it keeps causing me all kinds of problems, and I am not sure if it is my fault, a hardware fault or something else. Ill describe what I've done to it; When I got it I wiped the hard drive and did a clean install of OSX, then I imported everything from my old mac through migration assistant. However when I then started using my new mac, the 'home' folder was a different name so some files didn't match up, like my dropbox account and some games. I don't know if this has caused other problems within the directories or anything like that. It is usually fine for about 6 hours, it's pretty quick and I have been through disk utility in this time and the verify process has been ok. However after this time the it starts being REALLY slow. Like I'm talking 10 - 15 minutes to open an application. Every time this happens I open disk utility to check on it, and it always needs to be repaired as there are folders and directories missing. However when I turn it off and go into disc utility through the install disc it doesn't let me repair it as the drive cannot be unmounted, but then the HD disappears from disk utility completely. On top of this I tried to install XP through boot camp earlier, but the partition wouldn't format, so I went back through boot camp assistant and deleted the partition. However whenever I turn it on I have to hold down the command key and select the Macintosh HD, because if i don't it tries to boot into windows, even though the partition has been deleted and the HD merged back into the Mac HD. When I boot through the command key, the only option there is the Mac HD, so I don't know where it is getting windows from. The battery is not what I expected in this thing either. I have put this on another post but I wanted to complain about it again. I have noticed that on a full charge i only get 6 - 7 hours browsing the internet, way off the 'approximately 10 hours'. When I go into istat menus apparently it has a cycle count of 68 and the health of the battery is 89%, which seems very low to me. Oh and another minor thing, whenever I do manage to get it to turn on, it never remembers my settings for the back lit keyboard or the screen brightness. They are always on full whack even though I turn them down to half every time I use it. Basically, on this fine christmas day (don't get me started on that, the dog got more presents than I did and now my mum is singing Susan Boyle at the top of her lungs... JOY) I was wondering if any of you could help me with these problems? I'm thinking I may just have to wipe the HD again and reimport everything manually but I really don't want to do that. I do love Apple Macs and I don't want to get rid of this thing, but it is driving me MENTAL. PS. I turned the Macbook Pro on when I started writing this on my old Macbook. It is now 8 minutes later and it has still not booted. It is just sat there looking all smug with the spinny thing below the apple on the grey screen.
