ran the installer. Then I rebooted off the freshly formatted drive, ﬁnished up the niceties like signing in to iCloud, and ran the Yosemite updates from the Mac App Store. (I could have avoided this by downloading the updated installer, but I ﬁgured the updaters would be smaller. That may not have actually been true.) Now to put my data back. Remember, I was starting over. Migration Assistant had been bringing forward some amount of unidentiﬁable cruft dating back to 2003 that I was trying to get rid of, so using it was not only not an option, not using it was the whole point. I needed to copy things back in old school. When you have enough backups, weird error messages like this aren’t a cause for (much) concern.
Documents, my iTunes library, and the Mail mailboxes copied back from the drag-and-drop copies I made with no problems. The Photos library, however, failed to copy back saying “some data in Photos Library could not be read or written”. Ah, yes. Probably all of my ineffable photos. Understandable. They do have a certain je ne sais quoi about them. Well, this is why I made three copies. The copy from the SuperDuper backup worked ﬁne. After importing the Mailboxes to Mail, I pointed iTunes and Photos to the correct libraries. In iTunes you can change this through Preferences or by holding down Option when starting the application. In Photos the only way to do it is by holding down Option. I noticed both applications have different prompts for selecting a library at startup because the person in charge of consistency at Apple was off that day. I also had to reinstall Java for the Minecraft server, but I left Flash behind (it’s long gone from my MacBook Air). I refrained from installing any of the dozens of third-party applications that had been on the machine previously. In its role as a data host, it probably won’t need them. Now I had a fresh install of Yosemite with all of my ancient data, but without whatever Bush-era settings were causing problems. I wouldn’t say it’s exactly like getting a brand new machine, but it’s at least a major improvement. Because I left a host of applications behind, I have far more drive space. Things behave better almost across the board. It’s faster, happily lets me screen share, reboots without any trouble, and has its own new name instead of the one I migrated that it didn’t want to change. While this process takes some time, I recommend it if you’ve used Migration Assistant and OS X upgrades over existing installs for years and have a Mac that’s giving you ﬁts. C

folder on the drive I wanted to reformat and ran it. It rebooted and started the Yosemite install process, but it never gave me the option to format the drive. When the process was done, I found I had the same user account, just running 10.10 instead of 10.10.4. That… was not what I wanted at all. I had thought you could reformat the drive via that process, but apparently it’s not an option when you’re running the install from the drive you’re installing to. I could have booted into Recovery mode to run the installer, but then I would have had to wait for it to download. Who’s got time for that in this economy? But guess what I had? A bootable FireWire 800 drive copy made via SuperDuper. So I booted off that, reformatted the internal drive and
