High Sierra No Longer Supported

[#1]

Hello All, I have a mid-2011 iMac which has been updated to its last os, which is High Sierra 10.13.6. Since this is no longer supported by Adobe, what can I do? (Aside from buying a brand new computer right this instant.)

Priority-wise, what should I do right now with regards to my files and their integrity? I thought I had until November 30, 2020, but CC will not update almost most of the programs that I use heavily. 

Any assistance and/or ideas would be appreciated.

I've moved this from the Using the Community forum (which is the forum for issues using the forums) to the CC forum.

Use the old versions that work now for you.

Make sure you turn automatic cloud updates OFF so you don't have an update download that you can't use, and which might disable what you already have
