I have successfully installed Zorin and other distros on Mac hardware and they run flawlessly. However, the bootup time is quite long with the blank light grey screen showing for about 20-30 seconds before the distro starts booting.
Does anyone know how to reduce or eliminate this lag?
At Start Up (DGUNGGG...) Press Option to get to Boot Manager - Then Press CTRL and Click the disk that the Linux Installation is on - This appears to set it as the target disk - and away you go!! - I'm not fully sure what it does but It seems to Bless and make the chosen disk the Primary startup disk all in one hit.
I hope this helps someone else trying to do a similar thing - and it's probably worth trying anyway - as a CTRL Click is pretty easy to do!!
All the Best, Damo.
