My Ubuntu and Mac both boot perfectly on my Mac Air. I have about 240 GB for each. But my Ubuntu tells me my efi partition only has 6mb of remaining space. In addition, my Ubuntu sometimes freezes after which I'm not sure if this is related.
Anyway, would I need to resize my efi partition with Mac? I'm running el capitan. Everything concerning booting is running perfectly with ReFind, so I don't want to change too much. I'd just like to dedicate a little more space to my EFI partition.
