And just in time for MagSafe's return...the iPhone will go to USB-C! Of course, you can still charge a Mac over USB-C — it's just not as much of a unification as it seems.

Does MagSafe charging cause a Macbook Pro to heat up in the same way that USB-C charging on the left side of the device does?

When I saw that on my new M1 Max, I assumed so, so I never used it. (Also because I had USB-C charging for everything else...except my iPhone.)

  • Wasn't that just an issue with the final 16" Intel MBP? I don't think any M1/M2 Macs have had that problem.

    • If it is, then I've just had rotten luck, because every time I notice "hmm, that's toasty" it's plugged in on the left side. Absolutely no science done, to be fair.

  • Nope. My MacBook Pro w/ M1 Max has never even gotten warm, even while plugged in with MagSafe and pegging every CPU at 100% with SIMD instructions.

    • Cool (ha!) good to know. The times I've noticed mine getting pretty toasty when charging was from the left side, so I consciously try to avoid it (apparently a sibling suggests it's Intel only, so it totally could just be selection bias on my part). Regardless, I'm glad MagSafe doesn't have that problem. Thanks!
