Hi,
My 2011 iMac's hard drive has gotten so slow it's basically unusable. I have a 512 GB WD MyPassport SSD and have successfully used it to boot up the iMac and am running on it now. The external SSD uses a USB C port, but it came with a USB A adapter as well.
This is where I have an issue. The iMac has USB 2.0 ports, and I am getting 30 MBps read/write speeds. I got the Apple Thunderbolt 3 to Thunderbolt 2 adapter so I could connect the external SSD to the iMac using Thunderbolt instead of USB 2.0. But when I plug it in through Thunderbolt, the iMac won't recognize the external SSD at all. I tried restarting, ejecting, resetting NVRAM, nothing worked. I even tried plugging the external SSD with Thunderbolt to my 2014 Macbook Pro, it wouldn't recognize it either. I tried using another external SSD I have, with the same adapter and cable, it wouldn't recognize that one either.
Is there something I am missing here, with Thunderbolt connectivity or the adapter? Does it only work with USB? I've searched online but can't find anyone mention this issue. The external SSD won't even show up in Disk Utility through Thunderbolt. But when I unplug and use USB, it immediately recognizes it.
Any help would be appreciated,
Thanks.
