Everything I know is that it's not a hardware failure because if I wipe the hard drive, install OS X again it boots with no problems. Only if i install the Time Capsule backup/ just...

    Help!!! MBP 2012 shuts off when moved, stays off

    Hello! I'm desperate for help here... My 2012 MBP has decided to die and is not booting up. It essentially shuts off if it gets moved even slightly, which is highly impractical for a laptop. Then, it takes forever to turn back on and gives no signs of life during this time (last time it shut...

    Suggestions for bootable Firewire 800 enclosure

    I have an older Mac that I'd like to speed up a bit. On of the most obvious things I can do is replace the internal 5400 RPM drive with an SSD. I've done it before, but cracking an iMac apart is a painful experience I'd rather not relive. So I hit upon the idea of putting the SSD in a Firewire...

The first thing i learned when fiddling around with a hackintosh (back in '05 with deadmoo image) was the "rd=" option. So since i already successfully booted OSX from an...

    Spontaneous WIFI on at boot

    Hi all, every time I boot up my MacBook, it switches the WIFI on, wanted or not. It does not happen when I wake it up by opening the lid, and it never happened with my iMac. Is there a switch to prevent this? Thanks. ;JOOP!
