Unfortunately my Imac 27" Retina Late 2015 doesn't stop crashing with the Pegasus2 R6 connected to it.
I've attached the subsysteminfo file in hope to find a solution to go on working with this amazing harddrive storage.

I too am having a problem - in this case, with my Pegasus



I too am havinga similar problem , in this case with my Pegasus R4.  I am not, unfortunately, too savy about computer systems.  What happened was that my house fuse started blowing two days ago - just shortly after I reconnected the Pegasus.  Drive #4 lit red and then the house switch fuse blew again.  This happened a few times.  Now the Pegasus will not activate at all.  I note your advice to a previous customer about finding the subsystem info. on the top of the window,  I don't see that or the utility.  I have a Mac 27" - about three eyars old.. using version  12.2.6.   Please advise.

I am experiencing the same problem!  Did a clean install of High Sierra and behavior continues.  Were you able to find a fix?
