    I've got an early 2009 Mac Pro 4,1 that's often booting to a black screen that hangs indefinitely until I manually restart and try to power on again. This seems to happen about 60% of the time when I try to boot up. Tried resetting PRAM and NVRAM but these resets didn't resolve the issue...

    I left the church of Zapping PRAM but have returned

    I've used Macs since they came out. I used to routinely zap PRAM about once a year as part of regular maintenance or when boot problems arose. Over the years, maybe 5-10 years ago, zapping the PRAM didn't seem to help so much, so I drifted away from using it and didn't miss it. I love Mac...

    MacBook Pro will only recognize one specific internal hard drive

    I'm working on a friend's MacBook Pro that would start to a flashing folder with a question mark. The directory was out of whack, so I repaired that.
