Plan on dual booting Linuxmint 21.1 Cinnamon On a mac. Never dual booted or installed on efi machine. mid 2011 iMac running OS X 10.13.6. I TB drive. Have been running live session from its optical drive. Not sure what additional partitions to make, how big, order to put them in. I know I need to shrink the mac partition using it's tool before installing mint. I will split the drive approximately 50/50.

If you don't know your specific needs, simply present the Mint installer with reasonable freespace, and it will create the partitions it needs. Most Linux installers have this capability. Mine looks as follows:

Code:

# parted -l
