I just upgraded to Sierra and now I kernel panic (stack trace right back to the promise pegausus J4 driver) when I book if the J4 is connected.
I have seen responses to El Cap questions just brushing this off as an EOL product, but it's only 3 years old! Not to mention, it wasn't cheap.
I'm hoping that there is some chance someone either plans to fix the driver or knows a workaround.
Thank you all of your valuable input on this incompatibility problem of the legacy Promise J4 product with the latest Mac OS Sierra.
Promise's engineers already nailed down the root cause and put a fix on it. The patch is being verified and tested. Final fix should be available for public very soon. Please give them a little bit time to complete the test before releasing.

One more to the J4 crashing a Mac mini...
Maybe while the team are sorting out the issue here they could make this thing bootable too!
I have the same problem. If the J4 is not connected, the mac mini works well. When connecting, Sierra crashes.
My J4 is 3 years old, can't image why they would not support this OS. It wasn't cheap.
I'm having the same issue on two seperate machines on my 2014 MBP and 2011 Mac mini. They both have a kernal panic as soon as I plug in the J4
i've the same problem with my MacPro late 2013 and my MacBook Pro 15. I downgraded to El Capitan. I sent an email to the promise support...i hope they have a solution
Mac Mini - same issue
iMac 5K - same thing
And as others here have mentioned, the kernel panic is instantaneous in the same moment when the Pegasus J4 system is plugged in. Promise obviously needs to do something and get it fixed.
Nothing from Promise here. Time to take this to Twitter & Facebook.
Hi,
Please help us with the Mac system profiler so we can check the Kernel logs for what caused the Kenel panics and assist you.
Mac system profiler (Click Apple Icon > About this Mac > More info > System Report > Choose 'File' & 'Save')
You can upload the System profiler to a file sharing service and give us the link or upload it in the forum reply.
Thank you

I'm out of office for a couple of days... wish I could help but immediately. I'll upload as soon as I return on Saturday. Hopefully you'll have a cause by then.
Hi again,

Same thing here, had to time machine my way back to El Capitan, as I use the J4 every day. I really hope Promise does something about this, and soon.
Promise team is looking at the logs and seeing what we can do. Thank you for all your input.
