Keyboard not working after booting into Recovery Mode
Hello,
i have a 15-inch, Mid-2010 Macbook Pro that was running macOS 10.12.3 Sierra. I've just recently installed a 240 GB SSD and a 2 TB hard drive in the place of the optical drive with a data doubler. I've also upgraded to 8 GB of RAM from the stock 4 GB.
My problem is this: The keyboard works when I initially boot up the Macbook Pro, I hold [Command + R] and it boots into recovery just fine. However, once I am in recovery mode, the keyboard does not work anymore. The trackpad works fine, and the only thing that works is the green light on the [Caps Lock] key. The Time Machine backup I have of my old hard drive is encrypted on an external hard drive, but I cannot even type the password to restore the backup to my new SSD because of this keyboard issue. I've tried using an external USB keyboard and that does not work either. I've searched online and no one seems to have had this exact problem. Has anyone ever had this problem and can anyone offer a solution?
Thank you in advance
MacBook Pro, macOS Sierra (10.12.3), null
