Please note, If you encounter any prompt for administrative elevation, then proceed to the Self Service method below.
This update method requires no administrative rights.
Launch the Self Service app in your dock.
Allow roughly 1 hour for the upgrade to complete (older Intel Macs may require longer). After around 45 minutes you will need to log into your computer and the upgrade will continue for another 15 minutes. Your computer should then be ready to use.
Your computer may feel slightly slower immediately following the upgrade, especially on Intel Macs. This is due to the re-indexing of files on your disk for Spotlight and other optimisations. This should not take longer than twenty-four hours. We are not aware of incompatibilities with any software that Orchard currently provides.
If you have any questions or macOS 15 Sequoia upgrade is not available to you, please contact your local IT Support. For contact details, see Support
