I notice that Disk Utility in El Capitan is totally new - it even looks different. I also notice that it would seem to allow me to Partition my rMPB SSD drive without erasing the current drive. IN FACT, I am not even seeing the option to Zero Format or erase a drive with multiple passes like we have been able to do for the past decade.
Has anyone using El Capitan explored the possibility of partitioning an active drive so that Yosemite can be installed on the second partition for use with Protools?
