I am replying my own posting..and no snow leopard doesn't work on AC20...it says El Capitan or Yosemite!
I love my current 24" iMac running smoothly with Snow Leopard for AC17...and just feeling ambivalent to part with all of it or to go for AC20...! Do I really NEED to go for AC 20...really??
And if, I need to for speed, then I am looking into new computer and which one to go that will last me for the next 6 years [like I did for the current computer]...
3.3GHz Processor
2TB Storage
3.3GHz quad-core Intel Core i5 processor
Turbo Boost up to 3.9GHz
8GB (two 4GB) memory, configurable up to 32GB
2TB Fusion Drive1
AMD Radeon R9 M395 with 2GB video memory
Retina 5K 5120-by-2880 P3 display
Any thoughts?
