HS and SSD install issues
iMac 27" (Late 2013)
Samsung 850 PRO 1TB (Latest f/w verified)
No matter which OS (Mavericks through latest HS version) I attempt a clean install with (via bootable USB), I'm unsuccessful. The install appears to compete, however, upon rebooting I continue to see that the SSD is not detected (circle/line through it). I've troubleshot with HFS+/HFS+ Extended/APFS, but to no avail. I've troubleshoot with three different net-new 850's, but to no avail. These same 850's clean install on a 2008-based MBP, with no issues, period.
What am I missing here?
