mac pro Retina late 2013 15"
Just tried:
Sintech NGFF M.2 PCIe SSD Card as 2013 2014 2015 MacBook SSD
XPG sx8200 960gb
Device does not show up....
any ideas?
I just installed this SSD. Great price on Rakutan a couple days ago. $225 with CA tax!
I think your issue is that you're using the stock internet recovery image that's located within your Macbook (the 2GB disk0). You need to create a bootable High Sierra USB stick (search google) and it'll show up within the Disk Utility there. You could then format it before restoring from Timemachine or new install.
