Preliminary testing of Mac OS X 10.13 "High Sierra"

IT Services has spent some effort evaluting the current configuration management scheme vis å vis Apple's up-and-coming operating system code named, "High Sierra". The Managed Mac puppet module will not work with OS 10.13 in its' current incarnation.

Users are advised to avoid upgrading to OS 10.13 at all costs. Managed Macs running Mac OS 10.13 will be considered out-of-band and are unsupported until further notice.

Wireless upgrade March 31, 2017

Network Services performed a necessary upgrade for wireless certificates for today. A certain number of managed Macs were negatively affected as it rendered the existing wireless certificates inoperable. It will be necessary to get all managed Macs on wired Ethernet in order for Macs to take the new certificates successfully. Obviously, the majority of desktop Macs are unaffected.

Please note that if you do not have a managed Mac (ie. you're the main administrator of your computer) the correct course of action is to go to the Network Services XpressConnect page at:

  1. In most cases, the work-around to get these machines playing nicely on wireless again is to connect them to Ethernet and reboot.
  2. Should this not work within a few moments, you’ll need to force a puppet run and reboot
    1. FYI, the necessary command is: sudo puppet agent -t
  3. In extreme cases the old profile may be removed manually. This can be done in System Preferences: Profiles. Delete the profile named: Managed Mac: SFUNET-SECURE
    1. It is also possible to perform this via ssh with two commands:
    2. sudo profiles -D
    3. sudo puppet agent -t
    4. reboot
  4. Some Macs (especially loaner machines from the Library) have shown "SFUNET" in a higher precedence in "Preferred Networks". This should be DELETED.

IT Services strives to make computing at the University as smooth as possible, and we apologize for any inconvenience this may have caused.


Upgrade Information for OS X 10.12 "Sierra"

On September 20, 2016 Apple debuted its latest operating system OS X 10.12, code named "Sierra".


As with any new OS X release, IT Services urges all SFU community members to take a cautious approach when considering an upgrade.

Early testing reveals no major outstanding issues, but in an effort to remain safe and productive, we are advising caution with regards to 3rd party drivers and peripherals. Please check with your vendor if you are unsure whether devices will work with OS 10.12. It is common for new Mac OS updates to break compatibility with peripherals.

Most major software packages currently being maintained by the University have been tested with OS 10.12 and no show-stoppers have been found.


  • Konica-Minolta print drivers not available. However, Konica-Minolta indicates that the already-posted 10.10 drivers should work. More info is posted here.
  • MATLAB: Only version R2016b is compatible with Mac OS 10.12. More info here (As of September 20th 2016).
  • Trend Micro: Compatible as of version 2.0.3079. No further compatibility information posted by the vendor.
  • Fujitsu SnapScan devices are not compatible. More info here.
  • SFU Vault: Please be sure to install version 2.2.4 or higher (as posted on the vault site).


All Mac users who plan to upgrade to Sierra are strongly encouraged to perform a full system backup prior to attempting any upgrade.

If you are unsure if you have a recent full backup, do not attempt an upgrade. Please contact your local support person.

Those who have purchased or are planning to purchase new Apple Computer should contact your local IT support to discuss options.

Is my Mac compatible?

Compatibility information is not hosted at Apple's site yet.

As a rough guide, expect any Mac newer than 2010, with 4GB of RAM or more to be compatible. I.T. Services recommends 8GB of RAM (or more).


Please feel free to contact us about any of the above info!
