Restoring from Time Machine on Mac without video card I’ve got a Mac Pro 5,1 with an Nvidia P600 (Pascal) video card, running the Nvidia Web Drivers. One of the internal disks is its Time Machine volume. 

At some point it looks like automatic system updates overwrote the drivers, and the video card stopped working. Mac seems to boot correctly, I’ve been able to access it from a MacBook via Target Disk Mode. 

I do not have another video card that will work in this Mac. 

Is there a way I can restore the Mac Pro via Time Machine remotely?

I have seen various threads about using Screen Sharing but this was not enabled before the video card issue. 

Is there a way to log into the Mac Pro via the Terminal if I connect the MacBook directly to an Ethernet port? I don’t think I can connect with it over WiFi as sharing was turned off, but I can see if it shows up on the network. 

If so, what would I then need to do to 1) connect and log in and 2) restore from Time Machine from the command line? Step by step instructions for a command line n00b please :)

Thanks very much!
You are almost there. You could treat either the whole machine or just the system drive as an external HDD and attach it to your MacBook.

Attach your Mac Pro in TDM (target disk mode) to your MacBook. Boot into the Mac Pro’s system from your MacBook. Repair what you need to do.


Connect both computers.
Shut them down.
Power on the target Mac in TDM by holding the T key.
Power on host Mac with Alt/Option key pressed until you see MacOS boot manager.
Choose the target’s system disk
Boot
Repair graphic drivers, etc.
