    Corrupted EFI partition map or APFS container?

    My Macbook Pro (2012, latest Mojave) started having some hickups not long ago where the screen would freeze for a minute or two and then go back to normal. Then one time it just got really slow and froze up every 10 seconds so I tried to shut it down but it would only shut down to a black screen...

    MP 1,1-5,1 Mac Pro 5.1 won't boot with attached 4K Display

    Hello, I replaced my two 23" Apple Cinema displays with a 43" LG 43UD79-B 4K Display which has very much the same PPI as my old displays which I like. I'm using a 5.1 with the newest Firmware (144.0.0.0.0), a flashed Sapphire 7950 and a fresh Install of 10.14.5 on a PCIe NVME. I have read...

    MP 1,1-5,1 Mac Pro won’t boot

    Help! My 5,1 2010 Mac Pro won’t boot anymore. I’m hearing the chime, and it does all the usual stuff I hear when it’s booting up, but there’s no screen, nothing, it’s completely black. Yesterday I tried to install rEFInd, and did that successfully, only to realize my RX580 didn’t have a...

    Split Fusion Drive, now not booting, can't find solution!

    My 2011 Macbook Pro running El Capitan was running fine until recently when it suddenly decided to stop booting after getting a new charger which I assume was sketchy (refurbished apple from ebay). I believe that my fusion drive has split back into the original hdd and ssd and now I can't boot...

    Just Acquired... Now Dead

    Like the title says, received a brand new Mac Mini a couple of days ago and it is already dead. I can't get it to boot into any mode at all. Scheduled a trip to the Apple Store for the weekend. If they can't get it working there, I will probably just return it rather than shipping it off for...

    PCIe SSD boot problem

    Hi, I’ve recently upgraded the processors and graphics card in my Mac Pro and everything was working fine using OS Mojave. To speed things up I added a PCIe SSD Card and cloned it (Carbon Copy Cloner) from my existing bootable drive. I then set it to be my startup drive. Seems that this was a...

    Failed Boot - Early 2008 iMac

    Hi there. I own an old iMac but don't really use it that often. One day after attempting to start it up again, instead of the typical boot, I was greeted with a blinking folder with a question mark. As of a month ago, my iMac worked just fine. I had a relative login as a guest on it but I don't...

    Been having trouble with my mini lately. It's ~6 years old and running High Sierra (I think — need to confirm when I get home). Lately when I try to wake it from sleep, it won't wake up. I have to restart the machine in safe mode and THEN restart it again to get it to boot correctly. After...

    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...

    Mac Pro 4,1 Often Booting to Black Screen

    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...

    MBP won't boot - cannot mount root, errno = 19

    My mid-2009 mbp started to crash/freeze randomly a few times the last week. I ran a disk utility check when I still was able to boot and it said everything was fine. The next day it crashed again, and I haven't been able to boot it ever since – now two days ago. It boots and gives me the...
