Question: Downgrade OS Due To Slow Mac After Upgrade

I have a 20 inch iMac. It's years old. Originally it had Snow Leopard, now it's updated to Yosemite.

Since the update to Yosemite, my Mac is extremely slow. It's non response to clicks for 10-20 seconds.

I did everything possible to make it fast but nothing has worked so far.

Finally, I realized that Apple should not have let old Mac's update to their latest OS because it makes old Mac's **** slow.

I want to do the obvious thing - downgrade it back to the original OS - Snow Leopard.

BUT...

Like most Mac's my DVD drive had gone corrupt just in a year. So despite of having a DVD of Snow Leopard, I cannot install it.


Please help me with some option through which I can install the old OS in my iMac to make it usable again.

iMac, iOS 10

There could be a lot of other things that are making your Mac slow.

It maybe as simple as installing more RAM.

There could be other stuff in your system causing issues.

Before we go through a long and very tedious procedure of going backward, back to OS X 10.6.8 Snow Leopard


It would help us to help you if we could have some more technical info about your Mac.
