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.

Also, USB4 can optionally support PCIe tunneling, which is a fancy way of saying it supports plugging more advanced types of hardware in (like GPUs, high-speed network cards or NVMe SSDs) at speeds of up to 40Gbps.

And there is USB4 v2 (not kidding, that’s the name) which extends USB4 to up to 80Gbps, but there are no devices that support that yet.
