Upgrade logic board to support Thunderbolt 3
I have mid-2015 iMac 27" 5K, I've done a couple of upgrades to it CPU, SSD, & RAM in 2016. However, my system only supports Thunderbolt 2.
Last year I brought a new MacBook Pro 15" which supports Thunderbolt 3, because of different Thunderbolt versions, the iMac cannot connect to the OWC Thunderbolt 3 Dock working with MacBook Pro.
As I'm quite satisfied with my iMac's performance, I'm not looking at purchasing a new system to replace this one.
At this stage, I am thinking to a DIY upgrade, I am not quite sure if I purchase a late-2015 or later version of iMac logic board (Supports Thunderbolt 3) to replace the current one, will it work compatible with the other old model components?
Thanks a lot
