When I first bought this laptop three years ago, I really wanted to buy it with a one terabyte Solid State Drive (SSD). It was replacing a laptop with a nearly full 500 GB hard drive. I was buying it in a hurry, because the old laptop died, and I thought long and hard about ordering one with a larger SSD. I finally decided I couldn’t wait to order one custom-built, and I couldn’t afford the nearly $3000 price tag at that time. I’d been out of work for a couple of months in the summer, and it was nearly Christmas. I decided I’d go with a 500GB SSD.
As it turned out, when I migrated my data, I picked up about 50 GB of space, probably from deleting unneeded logs. Still, my photo collection continued to grow, and I offloaded my iTunes library to an external hard drive. This helped for a while, but once again space was getting tight. I’d already removed everything I easily could.
I did a little looking, and found that I could swap out my factory 500 GB SSD for a one terabyte model. I ordered the OWC Aura Pro X Complete SSD from MacSales. There was a video showing the upgrade procedure and it looked straightforward and something I could handle. The kit came with the special pentalobe and Torx screwdrivers needed to open the laptop case and remove the old SSD, and an enclosure to put the factory SSD into, to make it easy to transfer over my data.
The physical upgrade was the easy part. You have to use the five-pointed pentalobe screwdriver to remove the 10 tiny little screws holding the bottom of the computer in place. Then the battery has to be disconnected, the old SSD removed, and the new one slid into place and screwed down. While I had the computer open, I noticed a thick layer of dust clinging to the fans, and blew them out with some canned air.
The next step was to put the original SSD in the enclosure that came with the kit, so that it could be used as an external drive. Easy-peasy.
Getting the computer back up and running was the hard part. I plugged in the now-external hard drive and started it up, and nothing happened. Fortunately, I had the iPad, and was able to do a re-read the data transfer instructions. The next step was to try to start the computer in Recovery Mode, by starting up while holding down Command (⌘)-R. It connected to the internet, downloaded what it needed, and then showed the OS X Utilities. Unfortunately, neither the new internal SSD or the old external SSD showed up in the disk list. Fortunately, I tried reinstalling the OS, and when it did, it became clear: Recovery Mode was set up for Yosemite, and both SSDs were formatted in the new APFS (Apple File System) format, which Yosemite doesn’t recognize.
Back to the web. I had to figure out how to get the High Sierra version of Recovery Mode. Fortunately I found this support document on Apple’s site. With a computer like mine, that’s been upgraded, macOS Recovery will recover different versions of macOS depending on which keys you hold down when starting up. When you hold down Command (⌘)-R, as I’d done before, you get the version that originally came with the computer. This is why I’d gotten the Yosemite installer. What I wanted was Option-Command-R, which upgrades the computer to the most recent version of the OS available for the computer.
Once I did that, I got the High Sierra version of the macOS Utilities, which recognized both SSDs. I reformatted the new SSD, installed High Sierra on it, and checked permissions. Then I rebooted the computer and ran Migration Assistant on it to transfer the data from the old SSD to the new one. It was interesting to see how much faster Migration Assistant ran this time, copying data between two SSDs rather the Time Capsule and an SSD. When it first started up, it said it would take about an hour and a half to transfer the data, but the estimates quickly dropped. I’m not sure exactly how long it took because I had to go out and get the ice off the driveway.
So far, so good. The process was bumpier than I anticipated, but once I got to the High Sierra installer, I was pretty much able to run through the steps MacSales outlined on their website. It seems to have copied everything successfully, including my Keychain with my stored passwords, and now I don’t need to worry about filling up the computer when I import pictures.
