In other words, my Mac no longer remembered me or my password and all attempts to reset the password failed. Since a picture is worth a thousand words, these pictures will save you having to read a 3,000 word description of the errors I encountered Sunday afternoon and well into the evening. I long-pressed the power key and hoped for the best. I walked in to find my Mac as frozen as a popsicle. It wasn’t fun, but in retrospect, it could have been a lot worse. But, because I had good backups and stayed calm, I was back to work within a few hours without losing a drop of data. It took the better part of four hours before everything was back to normal. It turns out that erasing the disk before installing High Sierra was the solution. So, I restarted into Recovery mode, used Disk Utility to erase the troubled drive, and installed High Sierra.īingo. Neither one found any issues with the SSD.Īt this point I decided to erase the recalcitrant drive and start from scratch.

I selected the MacBook Air (in Target Disk mode) as the startup disk for the MacBook Pro and ran my go-to third-party disk utilities - DiskWarrior and Drive Genius. I put my MacBook Air into Target Disk mode and connected it to the MacBook Pro via Thunderbolt, and restarted the MacBook Pro while holding down the Option key. Holding my breath, I rebooted (for about the twentieth time), only to see the Apple logo (briefly), followed by the black screen of death. When it passed the tests, I reinstalled High Sierra. Then, I first ran Disk First Aid on the recalcitrant disk. I assumed the operating system was hosed, so I booted into macOS Recovery mode by restarting while holding down Command + R. The fans were still whirring, so I thought something might be going on behind the scenes. When I restarted the MacBook Pro, the Apple logo and progress bar appeared briefly, and then the screen went black and stayed that way. I booted from a clone of my startup disk (cloned the night before), and then used Carbon Copy Cloner to clone it back onto my (original, internal) startup disk.I tried a safe boot by restarting while pressing the Shift key.I tried zapping the NVRAM by restarting while pressing Command + Option + P + R.I remained calm while performing the usual tricks and techniques you perform when your Mac goes wonky: I noticed that all of the previously-colorful icons in my Dock were replaced with gray question marks, telling me that the Dock couldn’t locate the apps. When I tried to launch an app-any app-I got a message that the app was damaged and couldn’t be opened. So, I held down the power/eject key until I heard the comforting startup chime and soft whirring of fans. Target Disk Mode can be a real lifesaver in an emergency.Last Thursday morning I tapped the keyboard to awaken my Mac and nothing happened. You can run drive diagnostics, copy files to and from the volume, and even format the device. In Target Disk Mode, you can access the target computer's drive with the same freedom you would have with any other disk connected over FireWire. This trick is great for fishing files off of a machine that can't boot OS X correctly, since it operates independently of the Mac's installed operating system. When you are finished using the Mac in Target Disk Mode, you can unmount it and power down the target computer by pressing its power button.You can then treat the target disk as you would any other external FireWire drive. The target's internal disk should appear on your host Mac's desktop as an external drive.(The icon will look like a Y with a circle in the center.) Once the slave Mac has finished booting up, if you've found Target Disk Mode correctly, you should see the FireWire icon appear on the target Mac's screen.Then, power on the target Mac while holding the T key on that system's keyboard.Connect your target Mac to the host Mac using your 6-pin FireWire cable.First, if the Mac you want to access as your target is powered on, shut it down.Here's how you can take advantage of this capability: All you will need is a 6-pin to 6-pin IEEE 1394 - commonly known as a "FireWire" - cable.
