macOS support on the Trinity data network in offices and labs

Supported versions of macOS in Trinity offices and labs and on the staff Wi-Fi network

IT Services currently provides support for computers running the following versions of Apple macOS on the Trinity data network in offices and labs, and on the staff Wi-Fi network:

  • Yosemite (10.10), El Capitan (10.11), Sierra (10.12), High Sierra (10.13)

Apple has ended support for earlier versions of macOS. This means that they no longer provide software security updates for these operating systems and continuing to run these unsupported operating systems represents a security risk to the Trinity data network and to your own data.

If your computer is running an earlier version of macOS then we encourage you to take action to ensure you continue to receive full support from us by upgrading your operating system.  Information on how to upgrade, for free, to a more recent version of macOS can be found on the Apple website at www.apple.com/osx/how-to-upgrade.

macOS support on the student TCDconnect service

Supported versions of macOS on the student TCDconnect service.

IT Services currently provides support for computers running the following versions of macOS on the TCDconnect service in Trinity residences and the student Wi-Fi network:

  • Mountain Lion (10.8)*, Mavericks (10.9)*, Yosemite (10.10), El Capitan (10.11), Sierra (10.12), High Sierra (10.13)

*End of support for macOS 10.8 (Mountain Lion) & 10.9 (Mavericks) - 26th July 2018
Apple has ended support for macOS 10.8 & 10.9. This means that they no longer provide software security updates for these operating systems and continuing to run these unsupported operating systems represents a security risk to the Trinity data network and to your own data. For that reason, devices running macOS 10.8 & 10.9 will not be able to connect to TCDconnect service from 26th July 2018.

If your computer is running macOS 10.8 or 10.9 then we encourage you to take action well in advance of 26th July 2018 by upgrading your operating system.  Information on how to upgrade, for free, to a more recent version of macOS can be found on the Apple website at www.apple.com/osx/how-to-upgrade

 

32-bit app compatibility with macOS High Sierra 10.13.4

More information on alerts you may be seeing.

Following the release of macOS 10.13.4, the latest update for High Sierra, users will start getting the following  notification when launching 32-bit apps: "This app needs to be updated by its developer to improve compatibility".

This is the latest step in part of a gradual process by Apple to move to 64-bit app support only in macOS. Apple has announced that macOS Mojave (10.14) will be the final version of macOS to support 32-bit apps. 

If you wish to check which 32-bit apps you are running, use the following steps:
Apple - About this Mac - System Report. Then scroll down to Software and choose Applications and check the status under the 64-bit field for each app.
