Hi Folks, new here.
MacBook Pro late 2011 a1286, OS 10.9. My passport for Mac USB 3.0, 1 TB.
Disc was partitioned and formatted. 1 partition for time machine, the other for carbon copy (supposed to be bootable).
When using option key, to choose boot drive, WD external drive does not come up as boot drive.
Have read a few things; 1) not bootable (via firewire per WD website but I’m using USB), 2) try 2.0 USB cable, 3) use a combination of key strokes (Option-Shift-Command-Period) to load drivers.
The computer does (did) recognize the drive and has recent time machine backups. So does this eleiminate drivers as cause?
Any thoughts suggestions? I think the internal drive is faulty, it starts to boot then shuts off. It will open network diagnostics, but only error is battery, due to non-apple battery installed.
Thanks in advance…
