Hello! I recently installed Ubuntu Mate 18.04 on a 2015 Macbook Pro 13 Retina with a 500GB SSD and have encountered a strange problem.
On a “cold boot” (complete power down and then pressing the power button to start), it takes about 2 min 30sec from power on to get to the login screen. There’s always a gray screen that flashes once during that time. I think this is unusually slow but I don't know how to make it faster.
But if I restart the Macbook from within Ubuntu Mate, it restarts and loads the login screen in about 30 sec or so, which is what I think is normal.
I’ve done web searches but I can’t find any solutions. This isn't a suspension problem (I saw there's another forum thread about MBPro and suspension, but I don't face that problem).
Please advise? Thanks in advance!
