Chosen Solution
I would like to by this SSD upgrade kit, but in some places in Internet there are information about it does not support BootCamp at 19.1 iMac models. I need to know exactly, if it will work or not? I am planning to split ssd by 2 partitions and use MACOS and Windows on it.
As far as I know OWC support for BootCamp is limited to the older version SSD’s As you can see here Aura Pro X2 SSDs: Boot Camp Compatibility FYI - M.2 SSD support is not present on any adapter or drive. That leaves you to running a VM instead of BootCamp which is what I setup for some of my customers (VMware Fusion or Parallels Desktop) which works!
