To add to Servant of Cats information.
I had the CS6 Master Collection and intended to use it into retirement. But then Apple moved away from Intel CPUs. That killed any ability to run an older version of macOS in a VM for CS6. I could have kept one of our 2018 Intel minis I had CS6 installed on, but wanted to move ahead technology wise. That, and Photoshop is really the only app I would use with any regularity in retirement.
For other apps in the suite, I no longer had a need to so much as open InDesign. Illustrator almost the same. Premiere Pro and Encore? Kind of useless going forward as it can't produce a Blu-ray disk higher than 1080. No 4K or above.
When I sold the CS6 app, I had to include all of my other Adobe software with it as each was an upgrade. And legally for Adobe, all of the previous physical copies had to stay together. So the buyer got CS6, CS5.5 and CS5. Anything older didn't need to be included. I then filled out the transfer of ownership forms so the buyer would be new owner of those serial numbers. Those titles disappeared from my Adobe account, and were added to the buyer's.
The catch to that now is Adobe no long allows transfer of ownership. Or at least that's what I somewhat recently read. You might be able to activate CS6, but that's a big if right now. When I activated CS6 on my 2018 mini, it couldn't connect to an activation server. After three attempts, you'd get a message saying something in the order of "Oops! We can't seem to find the server." You then got a link to manually activate the suite. But, I don't know if you can even do that anymore. And Adobe will also no longer help over the phone with anything involving CS6 or older.
Wanting to avoid paying for the full CS suite in retirement (even after they offered it to me for $35 per month after I said I was dropping the full suite), I did this instead. The goal being to eliminate all subscription software, if possible.
Photoshop - dropped down to the Photoshop Photography Plan at $9.95 per month. You can no longer get that price. And I'm never going to let my license for that drop, or I'd have to sign up again at $19.99/month. I looked at Affinity Photo, but there are a couple of third party filters I use a lot, and neither works correctly in that app.
Illustrator - replaced with Affinity Designer.
Acrobat Pro - replaced with Master PDF Editor.
InDesign - replaced with nothing. I haven't had a need to build a book layout since retiring.
Premiere Pro/Encore - replaced with the full version of DaVinci Resolve. This app is particularly nice as you pay for it once, and all future updates and upgrades are free. You can't burn disks, but that doesn't matter anymore. I can output up to 8K video as an MP4, put it on a flash drive and view it on our UHD Blu-ray player from there. If I really, truly need a disk, I can output the video as Apple Pro Res and create a 1920x1080 Blu-ray disk in Toast Titanium.
Audition - replaced with the full version of WavePad.
I know this is a lot, but with Adobe making it nearly impossible at this point to use any of their older perpetual license apps, it's a far better choice to look at other titles that aren't subscription software, and will run on the latest, and much faster hardware.
