I have a MacBook Pro Retina (Early 2013) with MacOS X 10.11. To cut a long story short, due to issues with the NVIDIA card and graphics switching, I'm able to boot into single-user mode, but can't complete the boot past that into the Finder, so I would like to make a back-up of the data while in single user mode before taking the laptop to the Apple Store (since the graphics card issue is a known issue).
However, when in single-user mode, if I plug in a USB 3.0 disk, I get an error after about a second or so, once the disk has spun up:
AppleUSB30XHCIPort:: resetAndCreateDevice: failed to create device after (1) tries, disabling port
and no new device appears in
/dev. In contrast, if I plug in a USB 2.0 key, it appears in
I'm assuming this is therefore a USB 3.0 issue - is there any way to get this to work correctly in single user mode?
