I'm trying to get my Pegasus 2 R8 to work on a Mac Studio. I dowloaded the two files noted above, filter and the utility, followed the instructions so that the Secure Boot is "Reduced Security" and allows all kernel extensions. I installed the utility, and PromiseUSBFilter appears in System Information/Software/Extensions (version 1.0.5) and it shows that it's loaded. The Promise Utility Preferences show the port at 8080, the Set Notification Center Event Level as "Minor" and the Notification Poling Interval at 30 seconds, which I assume is the default. However, I still can't see it mounted. The Pegasus 2 R8 drive is running and shuts down when I shut down the Mac Studio, but yet I can't see it mounted. I note that the extension Promist STEX (version 6.2.13) is listed in System Information under software extensions, but it's not loaded. Should it be loaded and, if so, I do I get it loaded? I also note that the previous instructions on this thread were for a MacBook Pro with the M1 chip. Is there a different process, different filter/utility, and/or another setting in preferences that apply to the Mac Studio with the M1 chip?
