How to install macOS 26.0 beta with an IPSW file

Put the Mac you want to restore into DFU mode, connect it to a second Mac with a USB C cable, open Apple Configurator, then drag the downloaded IPSW file onto the device icon. The Mac will be erased and macOS 26.0 beta installed.

macOS 26.0 beta is prerelease software. Back up your device before installing it, and keep in mind that a backup made on a beta cannot be restored to an older public release.

Only files marked as Signed can be installed today. See every other build on the macOS IPSW page.
