Webb +Category: Tutorial 2017.11.03 + + APFS preboot install issues no more! + +Abstract + + Spoiler alert, Time Machine is trash. + +Body + + I was minding my business one day (October 27th) and I thought, oh! + What's this? A "recommended update"? "Oh sure, I'll update to macOS + High Sierra Beta 5, while I wait to pre-order my iPhone X at 3am." + Updating my OS is something I've done *countless* times before. Apple + waits until 1~3am to let me know there's a software update or just + performs one while I'm asleep. I awake the following morning to find + my computer more secure than it was the previous day. Guess what + happened this time? On the day of my friggin' *marriage* (at 2am)? + + I glance at my computer and see a software update…stuck. No worries, + I'll reboot! Okay, Recovery Mode! Also, Restore from Time + Machine…wtf? Why the hell did it stop at 39%? *opens logs* Can't find + linker for CoreSomethingOrOther? Good grief, reboot! Ghostbusters + logo in white, sans ghost. WHAT. THE. FUCK. I open the Apple Support + app, choose my laptop from my devices list, and chat with a rep. + After confirming I didn't want to book a Genius Bar appointment on my + wedding day, I shut down my computer and went to bed in a huff (I + prefaced my availability and was still asked…bruh). + + Fast-forward a few days and I'm talking to a nice Genius about my + computer issue (and Nintendo Switch, he's trying to justify buying + one). He performs many of the same things I did to try and get my + computer to work. Lo and behold, my computer lives! It breathes! It + scrolls the wrong direction by default (Natural Scrolling is WRONG, + you *heathens*)! I eagerly head home to perform a three-hour restore + from my Time Machine. + + 1. I done goofed + + I went through the same recovery process I've done days prior. + What did I see? GHOST. BUSTERS! Managed to get into Recovery Mode + to try for the last time, restoring via Time Machine, even though + I knew it would end in error. First though, I should reformat the + drive with Apple's File System (APFS)…*Could not create a preboot + volume for APFS install*. Welp. Time to fire up the iPad to search + for solutions. + + 2. Salvation + + After scouring the Internet for some *semblance* of a solution, I + stumbled upon a post[1] on Apple's own support forums by a user + named Ethoic.

Don't try to install macOS High Sierra again. + 2. Delete your drive until you have no drive. Seriously. + - Power off your Mac and then hold the `Command + R` keys + while booting. + - Delete your drive in Disk Utility. You should only see the + macOS Recovery Drive. *Leave this alone.* + 3. Reboot Mac and hold down the `Option + Command + R` keys to + activate Internet Recovery mode. Oh yeah, you'll need wifi. + Make sure you're connected. + 4. You should see a drive in Disk Utility. If you don't see a + drive and are unable to click the little plus button to create + one, reboot until you do…this was a little weird for me, might + not happen to you. + - If you do see a drive, reformat it as "Mac OS Extended" and + call it "Macintosh HD". + - There are a couple options for "Mac OS Extended". If you have + a Time Machine backup you want to keep, know that you should + choose "Case sensitive" if you setup your OS to be case + sensitive (as an example). + 5. Initiate Internet Recovery. + 6. Once the recovery is successful, use Migration Assistant to + restore from a Time Machine backup. + + Restoring from Time Machine from scratch has NEVER worked for me and + seemingly, 99% of the Internet. Absolute trash IMO. I'm glad I got my + data back but jeez. So many hours of my life wasted because of this + issue. And the productivity loss (but Super Mario Odyssey *gains*)! + Oh, and I'm not on the macOS beta anymore, haha. Other folks who have + the same issue didn't seem to be on a beta OS but you can never be + too sure. + + If you are currently on a macOS beta and would like to hop off + that train[2]: + + > On `System Preferences → App Store` you have an option called "Your + > computer is set to receive pre-releases Software Update seeds", use + > the button `Change` and select `Do Not Show Pre-release Updates`. + + Hope this helps! 🕸 + +References + + [1] <https://discussions.apple.com/thread/8106654> + [2] <https://superuser.com/a/845520> |
