I’ve a MacBook Professional 15" early 2011.
It has been gradual and full since a very long time so I made a decision to improve it with a Samsung 870EVO 2.5 SATA SSD.
Since then, I can not entry something.
I can not boot from a USB (tried 3 USB keys and Lion, Sierra and Excessive Sierra) white display of dying once I boot with the USB after the number of disk. I can not entry restoration mode (white display of dying after loading).
After I put within the outdated disk, I get an indication that I can not get by means of after loading with the emblem. I can not entry restoration mode both (white display of dying).
I can not kind a command in verbose (with outdated disk) plus it goes into error too.
Do you’ve gotten any concepts?
