I have a Pegasus2 R4 connected to a Mac Studio (M1 Ultra). The device is working great on macOS 15.7 (with the DEXT driver installed).
Does anyone know if this will continue to work with macOS 26 Tahoe?

Hi Robin,
I was unable to update to Tahoe immediatly after it was released, but I have now done so and the DEXT driver works well on Tahoe, no issues have been seen since the update.
The 2019 Mac Pro was also updated and the Pegasus also works well with Intel macOS Tahoe.

Hi, I've done all the updates for the MBP M4 but still doesn't recognise the R2. The R2 feels the Mac but not the way around. Any suggestions? Tks

Hi Alex,
please first check the driver installation status on your Mac.
Open a Terminal window and copy/paste below command and post the outcome here:
systemextensionsctl list | grep promise
The outcome should read [activated enabled] for driver 21.1.0
Kind regards,
Frank
