Tried to install the recommended thunderbolt 3 driver twice and both times my mac mini 2018, Mojave 10.14.2, crashed. No warnings...just rebooted. Not sure if I even need this but anyone else having this problem?

Hi Patrick,

We are sorry for the inconvenience caused to you. 

Are you trying to install thunderbolt software or Pegasus3 series driver for mac.Pegasus3 will require Pegasus3 series driver for mac

The Pegasus3 driver is causing the crash. The utility software installd just fine. Using the enclosure now without the driver installed and getting approx 500 MB/s read/write (tested with Black Magic Disk Speed Test). I have another Thunderbolt 3 enclosure with a software raid 4 (4 1TB SSDs) getting approx 300 MB/s write and 1100 MB/s read. Both enclosures are using a 0.5 m 40 GB/s cable daisy chained with the Pegasus3 connected to the mini.
