For me, as an SRE:

• Mullvad VPN
• Google Drive (until I set up my NAS)
• YouTube Premium
• ChatGPT (but I am thinking of trying out Claude 3 instead)

Other, non-tech subscriptions:

• Public transport
• Public bike sharing
• Food delivery

Things I might pay for if my employer didn’t:

• IntelliJ Ultimate
• GitHub Copilot

Random IT-adjacent services I occasionally donate to:

• Codeberg
• Wikipedia

That depends on your Mac. The older the Mac, the older the version. On most M1 Macs, you can go back even to Big Sur, on M2 it’s usually Monterey and so on. It might be different with the Pro/Max/Ultra variants though.
