Big fan of your OS X stuff! I still have a 11" 2012 MacBook Air with Core i7 and 8 GB RAM, if only I could use it as my everyday machine I'd be very happy!

I didn't know about Firefox Dynasty, it's very cool. (Wow, and Archive Plus and Preview Plus… you're killing it!)

What's your experience with those shady USB-C to Magsafe 2 cables/adapters? Old MacBook batteries are bound to deplete faster and faster every year, it'd be nice to be able to charge using what's most common nowadays.

I wouldn't trust the adapters. Maybe in theory it's possible to do it right, bridge PD negotiation to a 1-wire protocol negotiation but you've got to trust that they handled both the usb-c part correctly and the 1-wire part correctly.

There's not much rigorous testing I could find online, https://www.youtube.com/watch?v=Qg6pPDys-s0 tested a few and found that some spark when first connected, which implies they're not doing the 1-wire negotiation properly (real adapters will prevent arcing by sensing if it's connected first before increasing voltage)

Thank you!

I don't have experience--I would probably try to get a real one. I'm also a big proponent of getting batteries replaced. I know this all costs money, but if you like and are using this computer, make it nice!
