Hi all

I have an iMac (21.5-inch, Late 2012) 3.1 GHz Intel Core i7, 8 GB 1600 MHz DDR3 RAM, NVIDIA GeForce GT 650M 512 MB Graphics running OS 10.14 and plan on running 10.15 some time after a stable version is released.

I am planning on partitioning my 1.12Tb Fusion drive with most (about 80%) of the drive running the latest OS and the rest with a legacy OS which can be anything from 10.8 on for this Mac so I can run older versions of software, specifically Call of Duty 4 Modern Warfare and Adobe CS 4 (both 32 bit?).

My Question is which OS would be best to do this on (I still have all previous OS purchases available) and any advice on partitioning (like Partition or Add volume through Disk Utility)
