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?

I don't quite understand why you're running Snow Leopard which is a 7 year old operating system when Apple has offered OS upgrades for free and your machine would surely run El Capitan if my 8.5 year old one can? There have been 5 OS upgrades since Snow Leopard.

You are open to a variety of security weaknesses by running an old version that Apple has not maintained in years.

The only reason to run SL is if you have old Power PC (PPC) software - such as versions of AC prior to 10 - that you must be able to run. If so, best bet is to clone your hard disk to an external drive so that you can reboot to Snow Leopard should you ever need to - and then upgrade your OS.

No need to part with your iMac, just your out-of-date OS. Run Software Update to make sure you're completely up-to-date with the final SL release. Clone your drive. Then open the Mac App Store and download El Capitan.

You can clone using Disk Utility (format new drive, then click Restore and point to the boot drive), Carbon Copy Cloner, Chronosync and many other utilities. If you Google how to clone a Mac boot drive you'll find lots of tutorials. 🙂
