Can I use a 2012 magsafe charging cable on a 2020 macbook air M1

Hey there!

Regrettably, no. The MacBook Air (M1, 2020) doesn't use a MagSafe connector for charging. It has Thunderbolt / USB 4 ports that support charging.

If you need a new charger for your MacBook Air (M1, 2020), you can use the 240W USB-C Charge Cable (2 m) - Apple, and pair it with an Apple power adapter:

• 30W USB-C Power Adapter - Apple
• 35W Dual USB-C Port Power Adapter - Apple

Hope this helps!

There have been several versions of MagSafe over the years.

The current version is MagSafe 3 – and as far as I know, there are no adapters to go from MagSafe 1 or 2 to 3. So you would not be able to use that old cable even with a MagSafe-3-equipped Apple Silicon notebook.
