Apple's macOS 26 update has sparked mixed reactions among users, with some embracing the new Liquid Glass design while others find it problematic. For those who prefer to stick with macOS 15, there are now solutions to block upgrade prompts and even downgrade if already updated.

Rob Griffiths discovered a method to stop the persistent upgrade notifications using configuration profiles. By modifying specific settings, users can defer these prompts for up to 90 days at a time. This involves changing the forceDelayedSoftwareUpdates setting from true to false, effectively silencing Apple's upgrade pressure.

For those who've already upgraded and regretted it, ArsTechnica's Andrew Cunningham provides a detailed downgrade guide. The process requires creating a USB installer with at least 32GB of storage. However, users with M5 chip devices face limitations - currently only the base model M5 MacBook Pro lacks downgrade options, though this will expand to newer M5 models launching this week.
