This has been an option in Android network settings forever: randomize your MAC. I think it's enabled by default now? It's a basic privacy feature; you can be fingerprinted by your device's MAC.
How does that work with MAC address conflicts and clashes? I naively thought every MAC address had to be unique.
Is there a specific scenario where time limited wifi is common place?
Alternatively, if you don't want to run the whole Electron app, the money is this line: sudo.exec("/System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport en0 -z && ifconfig en0 ether `openssl rand -hex 6 | sed 's/\(..\)/\1:/g; s/.$//'`",
Why does a Mac-only app that shows a menu bar icon and a notification popup need to be Electron…? That’s 30 lines of Swift, max.

Nice, added it as a bash alias. alias randommac='sudo /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport en0 -z && sudo ifconfig en0 ether $(openssl rand -hex 6 | sed "s/../&:/g; s/:$//")'
So I tried this out on macOS 26 and the `airport` command is no longer there. There is a `airportd.sb` file, which appears to be some permissions based thing in s-expression/LISP. Weird. Edit: Spun up a macOS 15 VM and I got this: WARNING: The airport command line tool is deprecated and will be removed in a future release. For diagnosing Wi-Fi related issues, use the Wireless Diagnostics app or wdutil command line to…
Glad this feature is built into most modern operating systems these days. For MacOS (Sequoia+) you can just forget the network and reconnect to get a new MAC address [1]. Android's documentation for if it decides to generate a new address per connection is a little vague [2], but I'm guessing forgetting and reconnecting works as well, you may also need to flip the "Wi-Fi non-persistent MAC randomization" bit in devel…
Yeah I had to flip the developer setting toggle, but worked flawlessly for my flight (American Airlines has a watch an ad for 20 minutes of free internet that only works once per MAC)

Well, if you COULD ship something across the world on a private 747 with extra features to protect your cargo, and it has nearly no environmental downside and has no meaningful downside vs a smaller airplane… you’d probably do it! There’s no incentive in software to get a smaller, more efficient plane, and plenty of incentive to use the big thing for free that has all the extra features
> it has nearly no environmental downside and has no meaningful downside I think this is not the case. E.g., we replace our computers every few years, but not because the new ones can do things that you can't do with your current computer. It's because the software you use to do the same things keeps getting more resource-hungry.
