    Default Macbook pro 2012 will not start up.

    Hi All- My 2012 Macbook pro ( 13 inch non retina, dual core i5, 8GB ram and 750 GB HD ) will not start up- It has been on the spinning wheel for 10 minutes so I just had to turn it off. I tried it two more times and would not start so I have started it up in target disk mode and am copying all my data off in case it hasn't all been backed up. (Thank goodness for firewire still being on this Mac!!!!)

    Earlier today it sat on shut down for way too long so I just had to press the power button to get it to shut down. It is running a clean install of Mountain Lion from a month and a half ago. It has a Month and a half old hard drive and is treated very well.

    However since Mountain Lion 10.8.2 it has had a ridiculous number of problems, in slowness, USB problems, apps just unexpectedly quitting, shut down going on for ages and ages and start up taking too long. Apple continually tells me there is no problem with it. For a laptop I spent a huge sum of $1200 I expect far better than this.

    Are my next options to try safe and verbose startups when it has backed up? Another horrible genius bar opiontment? Maybe I should just tell them how every single one of my apple products I have purchased other than for my collation (Leaving out my iPod shuffle) has had problems? I'm just so over this.

    Update - it refuses to startup in safe mode, it hangs in rebose and single user mode. It passes the apple Hardware test and it booted into the recovery partition and I verified the disk and it came up as fine.... However it still will not boot.

    You could try a PRAM reset. Turn it off. Turn it on. Await the 'chime', then immediately press and HOLD CMD-OPTION-P-R keys altogether until you hear a second 'chime'. Release the keys and let it boot up.

    I've done the above on a few machines. Sometimes it helps not, sometimes it helps a lot. Resets the parameter RAM. You have nothing to lose by doing it.

    If you have an external drive you could install OSX to that and boot off that to see if it's quick - would eliminate the hdd as the problem?

    Strong recommendation. Get CCC or SuperDuper! and create a clone which will boot the machine if it won't start up. Two advantages... you will always have a bootable drive and you will always have the most recent copy of your internal drive (because you will clone nightly... less often if not much changes). Time machine is useful but its not bootable. The thing is, hard drives fail. Its practically guaranteed. Some fail in a year, some take years to go, but go they will., sooner or later. Do the clone, and switch drives from time to time anyway, in case the clone fails. (Trust me on this... I learned the hard way... and SuperDuper! saved my bacon the next time)
