[QUOTE="mickfish, post: 1789705, member: 398890"] Just received , here in Sydney, the G Raid with Thunderbolt 3 16TB bought from B&H. I have an iMac 15.1 27" late 2014 5K Retina, with 2 x Thunderbolt 2 ports. I am running Sierra 10.12.6 I have connected the G-Raid as follows: inserted in to one of the G-RAid Thunderbolt ports is the male end of the Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 female adaptor cable. Then connected to the female Thunderbolt 2 end is an Apple Thunderbolt 2 to Thunderbolt 2 cable, which is connected to one of the two Thunderbolt 2 ports on the iMac. I have attempted numerous times to mount the G-Raid, but it is not recognised. I have disabled my firewall and removable media blocking software (Eset). I have changed connection to alternate ports on both the drive and computer. I have turned on the G-RAID after booting up computer and tried turning on before booting up. The G-Raid does not appear in Finder nor in Disk Utility. In “About Mac” I see that the Thunderbolt ports do not see the device. From the "About Mac" - Hardware/Raid Devices, I see "This system doesn't contain any supported hardware RAID devices. If you installed hardware RAID devices, make sure you installed them properly." I have also tried connection from the Thunderbolt 3 on the G-Raid to the USB port on the iMac- again not recognised. But my standard 4TB G-Drive and a Seagate external drive are both recognised when connected via USB to the iMAc. I connected the G-RAID to my Macbook Air using the Thunderbolt?USB-C cable and the Macbook immediately recognised it. So the problem appears to be the iMAc. I did a PRAM reset on iMac (holding Option+Command+ P+R keys)- still does not recognise when connect via USB or Thunderbolt. Appreciate advice on resolving this issue. [/QUOTE]
