I have a G-Speed Shuttle XL that is about three years old (it’s a many-thousand dollar 80 TB unit that I clearly don’t want to replace - it’s still sold new for $6399). It was connected to a 2014 iMac 27" and always worked fine. That iMac was recently replaced by an iMac Pro, which, like an increasing number of recent Macs, is Thunderbolt 3 only.
It should work with an Apple Thunderbolt 3 to Thunderbolt 2 adapter, although I am aware that it will, of course, give Thunderbolt 2 speeds. Since connecting it to the iMac Pro using the Apple adapter, it has intermittently dismounted and remounted itself (oddly, it worked for a couple of days before the problems started). Searching the forum for the problem, it could be the Thunderbolt cable - I didn’t have a second cable long enough around, but a high-quality cable arrives tomorrow. I also began to suspect the Apple adapter. I did have two of those around, and swapping adapters does not help. Is it possible that the G-Speed Shuttle XL is simply incompatible with the Apple Thunderbolt 3 to Thunderbolt 2 adapter?
If it is incompatible with the adapter, what’s the work-around? There are several non-Apple adapters on the market, most of which are more expensive than the Apple version, but clearly worth it to connect the valuable RAID. Is there one of them that G-Tech recommends for that unit? I don’t want to buy several different hundred-dollar adapters in hopes that one of them works. Alternatively, does G-Tech have a program to upgrade the Thunderbolt 2 chassis to Thunderbolt 3, either via a board swap or a return and replace program?
