Apple account and @kth.se-address

Apple accounts are tied to you as an individual, not to your employment. Never use your @kth.se address when creating an Apple account – it will stop working when your affiliation with KTH ends, and you risk losing access to purchased apps, iCloud data, and other services linked to the account. Use a private email address that you own and control.

If you already have an Apple Account with a KTH address, you should change it to a private email address in Apple’s account settings. Read more on Apple’s website: support.apple.com/en-gb/109353

Keep your Mac updated

Apple provides security updates for the three latest macOS versions: 27, Golden Gate, 26 Tahoe and 15 Sequoia. We follow the same support cycle.

We continuously inventory the computers and ensure they run up-to-date operating systems that meet today’s security requirements. If your computer is running an older version of macOS, you will receive notifications from us to upgrade.

If your computer is running an older version, you must therefore update your OS, according to our instructions for Updating Mac from older macOS .

If your computer is too old for these macOS versions, it may be time for a new Mac, with better security and access to the latest apps, features, and updates.

If you need help or have questions about updating, please contact it-support@kth.se .

Current macOS: macOS 27 Golden Gate

macOS 27 Golden Gate logo

Apple's annual major macOS system upgrade, named macOS 27 Golden Gate, was displayed at Apple's developer conference WWWDC 2026 and released September 15. The focus is on a better Siri, AI across the board, and refinements to last year's interface change.

macOS 27 Golden Gate runs on Apple processors only. It's also the last macOS version to support the Rosetta feature, which lets you run Intel-based applications on an Apple processor.

Compatible computers

Mac mini: from 2020 and newer with Apple processor

Mac Pro: 2023 model

Mac Studio: from 2022 and newer with Apple processor

iMac: 2021 and later

MacBook Air: 2020 models and newer with Apple processor

MacBook Pro: 2020 models and newer with Apple processor

MacBook Neo: 2026 model

No models with Intel processor are supported (iMac Pro, MacBook etc)

Preparing for an upgrade

macOS 27 Golden Gate has not been released yet, but ahead of the upgrade later this fall we recommend the following:

  1. Do you have an Intel Mac? Then it's time to consider a new Mac with Apple processor.

  2. Are you still running Intel-based apps? Check in System Settings > General > About > System Report > Software > Applications. If you find Intel applications, it's time to look for Apple processor-compatible alternatives.

  3. make sure to back up your computer and update all apps before installing the upgrade.

After the upgrade

Following every OS upgrade, macOS re-indexes the hard drive and optimizes the operating system. This process typically consumes time and system resources for a while. With this year’s focus on AI, Apple is updating Siri to understand the context of your files, which requires more extensive indexing. Please be patient if your computer feels slow after the update.

The computer labs run macOS 15 Sequoia

All Mac computer rooms in building 43:3 (Turkos, Violett, Konst and Musik) run macOS 15.x with local home directory and access to Windows home directories. Read more here: Your home directory in the Mac labs  

This page shows the software in the computer labs

The iMacs in the computer labs have USB-C ports only. If you need to use USB-A port for a computer lab session or for personal data storage, you therefore need an adapter.
