I'm configuring a new Mac with three installations of 10.13. I've divided the SSD into three partitions within the same APFS container and installed 10.13 on each of them. All three installations are encrypted via FileVault.
One of the installations in particular needs to be absolutely free from malware etc, so no additional software will be installed there. And one of the installations is a test OS for new software etc.
Is there a cross-partition security risk when you have multiple installations/partitions within the same APFS container, i.e. if I get a virus or malware on one partition, could this 'spread' to any of the other two partitions, or installing something like a key logger? Would it be more secure to have each installation in its own APFS container?
Any insights would be greatly appreciated.
