Hi:
I just got the USB to SATA III adapter today. I install High Sierra on a Plextor SSD, which will boot up nicely on my 2013 MacBook Pro, but when I install this SSD to the SATA interface of 2011 MacBook Pro, it will go through the initial Apple logo and first boot sequence, but then it became just white screen even though the fan is working hard. I switch to Yosemite, it is still the same behavior. I do notice some change through. I tried SCM and PRAM reset, it responded to SCM reset, but not to PRAM reset. Also the USB port is supply power to USB, but not responding to option key. I am wondering maybe my last ditch save will be trying to find or build a OS X Lion DVD installer, and they to reinstall OS X Lion from the DVD drive.
