Extending Thanks to all contributors that helped me solve my dilemma! I must have spent 8 hours reading tutorials and watching Youtube videos. This research provided clues but nothing conclusive until I reached out here. Quite a journey!
Now I can still use my legacy software such as Photoshop and MS Office but can also benefit from a more current OS and sort-of-current browsers!
Glad to hear you've succeeded. Just a heads-up: your iMac can run High Sierra as well, which would allow you to run current versions of e.g. Chrome and Firefox.
