Hello MacRumors, you beautiful bunch of clever minds. My early 2011 MBpro died suddenly last night, now it turns on (blue light on the right hand side of the keyboard comes on) but the screen remains blank and doesn't get to the boot noise or boot. I am hoping to be able to pick the...

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...

Alright guys, so I'm having some troubles with an old flowerpot iMac. About a month ago I knocked a glass of water on the desk where the computer is sitting. There was no splash to speak of, the water just spilled around the base of the iMac. I immediately pulled the plug, but didn't feel like...

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...

Hi all, My Mac Pro 1.1 upgraded to 2.1 has stopped booting up. It does not react to any key combinations after the chime sound. I have tried resetting PRAM, booti up from network, removed rams and all devices and left only 2 RAM modules in. It does not pick up any HDDs/DVD/USB, just sits on...

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. Then found out the hard drive is physically failing, so I cloned everything over to a new drive. I still had problems with drives being recognized...

Hello. Yesterday I decided to update to Sierra from El Capitan on both the disks on my Macbook Pro (mid 2012); the update on my SSD went without a hitch so I decided I'd update my other disk, too. I downloaded the .app and the installation started as normal; once it got to the point where I'd...

Hello folks, A bit of a long-winded explanation here as background to my troubles of today. Old 2007 Mac Pro (8 core) running OS X 10.7.5 (Lion, I believe) died. Thought it was a hard drive issue at first so I replaced that Seagate drive with new 3TB HGST model and Carbon Copy Cloned the...
