Had followed the driver's user's manual to install including the security policy changed from initial boot setting, it installed successfully showing in the hardware description.

But while the Finder is opened, this driver does not present in the list, no related disk is mounted.

Is ther any other way to let it run properly?

Or still need to wait until new version driver to get issue resolve?

Hello Joseph,

6.2.17 is the required driver for M1 MAC, please check if the extension is allowed from System Preferences. Check if the unit is working fine on other mac.

Which system extension needed to be allowed?
Could you share the path, thanks!

Hi Joseph,

It is PromiseSTEX, once you open system preferences it should already tell you that there is an extension to be allowed.

Please check if the boot security is still set to reduced security or not.

Also is the Pegasus working on any other MAC ?

Yes! The system security extension is allowed, and see the PromiseSTEX is as User's Manual mentioned, show as ARM instead of x86 architecture.

Is there any other setting to be done?

The Promise Pegasus2 R4 works well with x86 2014 Mac Mini with most updated MacOS 12.3 (upgraded yesterday).
