Mr. Macintosh Explains Another Way to Block the Software Update Prompts for MacOS 26 Tahoe

Last month I posted an item (linking to a post from Rob Griffiths) explaining how to hide the prompts in System Settings to upgrade to MacOS 26 Tahoe. The technique I posted involved hand-editing a device management profile.

This video from Mr. Macintosh shows how to do the same thing, but using the free iMazing Profile Editor to create the device profile instead of hand-editing the XML Property List. If you were spooked or put off by the original technique, but want to stay on MacOS 15 Sequoia and hide all the prompts related to Tahoe, watch this video.

MacOS 15.7.5 Sequoia came out this week alongside Tahoe 26.4, and it was delightful only to see the update notice for 15.7.5 in System Settings.
