Apple’s macOS High Sierra: You’ll hardly notice

“At one time, a new version of macOS might have been a huge deal. Apple would announce over 200 new features, and you could always depend on having lots of changes. Some visual, some under the hood. With OS X, Apple would deliver major changes in each release before adopting a tick-tock pattern,” Gene Steinberg writes for The Tech Night Owl. “So a recent example is OS X Snow Leopard, which refined OS X Leopard, and OS X Mountain Lion, which refined OS X Lion. You expect, then, that macOS High Sierra is the refinement of macOS Sierra.”

“What this means is that, on the surface, they really resemble each other so closely that you will be hard pressed to detect any difference at all, except in a few ways. It’s not that there are no changes, but it will convey a quick level of familiarity that will allow you to upgrade without much to be concerned about,” Steinberg writes. “Overall, then, I’d probably recommend the move to High Sierra, although there may be issues with the new Apple File System (APFS). Now a file system is a big thing. It reflects how files are managed and stored on your machine’s drive and thus, if something untoward occurs, you may find yourself having problems. ”

“The installation of High Sierra on a Mac with an SSD converts to APFS automatically. You can’t stop the process, although there was a checkbox that allowed you to skip the conversion during the beta process. So if there are any concerns at all, don’t do it. Or prepare to backup and reformat your drive as HFS+ after installation,” Steinberg writes. “As with all maOS upgrades since the late 1980s, I’ve almost always updated my Macs early on, often with access to betas (with ready backups). So High Sierra was no exception, although I was more careful than usual.”

      1. I upgraded to Office 2016 before High Sierra was released. Upon upgrading to High Sierra I’ve no problems, although applications seem to load and run faster (especially Office).

  1. iMovie 10.1.7 won’t stay in memory constant crashes and hangs. (nightmare)

    Was forced to revert to 10.1.6 (time machine is a wonderful thing)

    Other than that, and some broken older apps, almost a non-event. Main internal SSD upgraded flawlessly to APFS, as well as one internal HDD (both Apple) and two External, with one being a Raid.

  2. Looking forward to APFS on Fusion drive iMacs. Bought one in September just a couple of weeks before I found out that APFS would not be on Fusion drive equipped iMacs initially. I had been deciding between a Fusion drive and pure SSD. Would definitely have gone will SSD if I had known that APFS would not be available with the release of High Sierra. Seems like purchasers should have been alerted that their new iMacs would be rendered potentially obsolete by the next upgrade. Looking forward to getting it — soon hopefully.

    1. If you think your new iMac is obsolete, I’ll be glad to take if off your hands!

      Seriously, if you can’t wait to update until the .1 or .2 update (or whenever they work out the APFS software for the Fusion drive, since you CAN update to High Sierra now), you’ve got real problems.

    2. APFS or no..SSD will outperform a fusion…that was the case when you bought it…new vs old was just as obsolete then as now..especially since it was widely reported that the new file system it optimized for SSD. When they release it for fusion, SSD will still be better performance wise.

      I just purchased a maxed out 27 iMac…chose the 1TB SSD.

      I have a complex setup and had no issues at all updating to High Sierra.

      I did notice though..when I copied a 200GB file to the desktop and it was …instantaneous.. 😉


  3. Oh, I noticed, big time. If you are a pro with backups or pro software that relies on the old file system, wait. I have spent the past couple of days getting things back in order due to inconsistencies specifically with APFS. The future looks bright, but it isn’t fully formed enough yet to accommodate the changes brought on by this update. If you live on iOS, then go bananas. Everybody else, wait.

  4. Yes, you’ll notice…

    • If you want to run third party file system repair utilities that work on High Sierra. There AREN’T ANY. Thank Apple for being late finishing their APFS standard, the day High Sierra was released to the public. This is the prime reason I’m personally waiting to upgrade.
    • If you use a Fusion Drive as a Mac’s boot drive. APFS is Fusion Drive illiterate. Considering that Apple has literally spent over a DECADE working on a replacement for HFS+, this is beyond disappointing. [Expletives withheld]

    Again, I’m pulling out the Apple Prod. It’s the third time today. Oh Apple. 🤢😩
