      Two Problems When Connected to an iMac Pro

      I purchased this Pegasus3 system in December 2017 when I purchased my iMac Pro. I have two problems with the Pegasus3. When you install the latest Mac driver I purchased this Pegasus3 system in December 2017 when I purchased my iMac Pro. I have two problems with the Pegasus3. When you install the latest Mac driver on the Pegasus website, it installs a file named Pegasus2R2ICON.kext which causes immediate ejection of all USB hard drives attached to the iMac Pro. Remove the subject file and the drive ejection issue goes away while the Pegasus3 functions fine. With the Pegasus3 attached to the iMac Pro, I cannot boot into Windows 10 (installed using Bootcamp). The iMac Pro will simply hang at the Windows 10 logo screen with the spinning circle of white dots. Disconnect the Pegasus3 and Windows 10 boots up fine. Reatttach the Pegasus3 after windows 10 is running and it works fine. These are serious problems that I notified Promise Support about in January 2018 and I still have an open ticket with them. They have never resolved either problem. Beware of this Pegasus3 system if you plan to use it with an iMac Pro.

      Promise Does Not Update Drivers/Kexts

      I own a Pegasus2 R4 and Pegasus3 R4, with the Pegasus2 having been purchased from Apple in 2014 when I upgraded my Mac Pro5,1 to the current gen Mac Pro6,1 for I own a Pegasus2 R4 and Pegasus3 R4, with the Pegasus2 having been purchased from Apple in 2014 when I upgraded my Mac Pro5,1 to the current gen Mac Pro6,1 for external storage. Since then, Promise's KEXT's and drivers have been problematic on numerous OS X/macOS releases. Many have reported their Thunderbolt arrays randomly eject (the array's are properly connected to the correct Thunderbolt port on the array to the Mac without any other devices or displays connected and the latest software/drivers installed). I never experienced this issue however my Mac Pro consistently crashes due to a kernel panic with the necessary KEXT installed. As a registered developer, I have worked with Apple and Promise on this matter for the past three years and yet the problem persists. Currently it's worse with macOS Mojave Developer Previews. Shutting down or restarting my Mac results in a kernel panic due to the KEXT (which is 32-bit, amazing for the price Promise charges). I've uninstalled everything but the necessary KEXT, clean installed macOS numerous times, spoken with Promise Tech Support, followed all recommended procedures, and yet the problem's persist. I check Promise's site on a regular basis hoping for updated firmware, KEXT's, drivers, etc and they rarely update the required drivers for their products. They are well aware of the problems yet do not seem interested in maintaining this particular product line. I would highly suggest researching other Thunderbolt array's as Promise seems disinterested in supporting their Pegasus line of products.
