Mac Users, Please do not Install High Sierra Yet

Apple is about to release macOS 10.13, known as “High Sierra.” This is a relatively minor feature upgrade from 10.12 (“Sierra”), but has major under-the-hood upgrades. Here’s what you need to know.

The Bottom Line

(Well, yes, actually this is almost-the-top-line, but I want to catch you before you nod off mid-Tech Tip. And anyway, don’t you like to read the last page of a book first?)

Don’t upgrade to High Sierra right away.

We will sound the all-clear in a few months (well, hopefully), but if somehow you miss it, you can always check in with the IT Help Desk at for our current recommendation.

Hampshire Computers

If you have a Hampshire-owned computer, we are not prepared at this time to support High Sierra for several reasons:

  • High Sierra requires updates to the tools we use to recover files and re-install software on your computer and we do not have these in place—they are not even available yet.
  • We are concerned about stability of the system. There are often bugs in new software, and we have seen some crashes in prerelease versions of the system.
  • Some applications that are in use on campus reportedly no longer work in High Sierra:
    • Final Cut Studio 7 components DVD Studio Pro, Soundtrack Pro, Color, and Cinema Tools.
    • Microsoft Office 2011 (Word, Excel, Powerpoint)
    • Adobe CS5 products

    This is not a complete or final list.

Personal Computers

If you have a personally owned computer and decide to ignore this recommendation, please, please, please, make a complete backup of your computer before you do! This version of macOS makes significant changes to the way that files are stored, which increases the risk of file corruption during install.
