That looks to be in Apple's boot rom. Since it vanishes at the office in a few seconds (we changed the HDD to a SSD) I can't see the gain. Maybe it's worth replacing the entire laptop? (just kidding.)
I'm working on an older macbook pro from 2010. It's been updated by Apple from Snow Leopard to Yosemite without flaw, or so it seems. As for myself, I recently received a new 2014 macbook pro and noticed it has a new black boot screen. Is it possible to update the older macbook's white boot screen to the new one?
I searched on Google and came up with nothing, so I decided to leave a thread here to see what the world knows.
