SSD Upgrade Gone Wrong...Help
Samsung 850 Evo 500GB Installed.
I used a bootable usb of High Sierra and a sata-usb adapter. I formatted SSD and installed clean OS X High Sierra. Then using Disk Utility Migration I copied all files, apps and other stuff from machintosh HD to SSD. Before I swapped the drives I booted from SSD externally and it worked like a charm. I then swapped the old Mac HD with the SSD and ran disk utility again. I selected Samsung SSD which was now inside my laptop as the startup disk! So I pressed restart and my MacBook Pro will load the full bar but never actually leave that screen. Sat and waited for 3 hours. Tried repair on drive and had no issues. Started again and still it loads the bar and stays at that white screen with the Apple logo(full bar below). I have read all the posts and i’m Not sure if it’s the cable or a faulty SSD.
