Upgrading to macOS High Sierra Checklist


ITS has been testing macOS High Sierra since its release on September 25, 2017. We recommend that you only upgrade if your computer has at least 35GB of available storage space and a minimum of 8GB RAM. Before upgrading, make sure you have a backup plan and set aside plenty of time for the installation to complete.

If your Mac is currently running macOS Sierra, it most likely meets all of these requirements.

✓ Have a back up

Backing up your data is strongly recommended. Once the update is complete, there's no going back. Back up your data to your H Drive, Time Machine, or CrashPlan.

✓ Delete any previously downloaded High Sierra installers

During our testing phase, ITS blocked the installation of macOS High Sierra. If you attempted to install the software before Friday, October 6, you will need to delete and redownload the installer. Failure to do so may leave your computer vulnerable to a serious security flaw. Click Finder, choose Applications, drag Install macOS High Sierra to the Trash.

✓ Check software compatibility.

What are the most important software programs you use every day? Many programs such as Microsoft Office and Google File Stream (formerly Google Drive) are known to work great with macOS High Sierra, but some specialized software may need patches or paid upgrades before they work. If you aren’t sure, contact the ITS Help Desk at Faculty members may contact their Academic Information Associate. RoaringApps compatibility checker may have more information.

The following applications have been tested and launch successfully. ITS cannot test every function in these programs: ATLAS.ti, Citrix, Google Backup and Sync, Mathematica, MATLAB, ChemDraw, TeX, CrashPlan, Banner INB, VPN.

✓ Make sure I have enough storage space.

You need 35GB of available storage capacity. To find the available storage go to the Apple menu and choose About This Mac then Storage.

✓ Make sure I have enough memory (RAM).

ITS recommends at least 8GB of RAM, otherwise your computer may run very slowly. To find the memory (RAM) go to the Apple menu and choose About This Mac then Overview, look for Memory.

✓ Make sure my hardware is compatible if I want to use High Sierra’s new features.

We only recommend the update for the following computer models. To find your model, go to the Apple menu and choose About This Mac.

Mac Pro (late 2012 or newer)
iMac (late 2012 or newer)
Mac mini (late 2012 or newer)
MacBook Pro (mid-2012 or newer)
MacBook (Early 2015 or newer)
MacBook Air (mid-2012 or newer)

✓ Make sure my operating system (OS) is compatible.

Your Mac must be running OS X 10.8 or later to receive the update. To find the version of OS X, go to the Apple menu and choose About This Mac, look for Version.
OS X El Capitan v10.11
