Answer to: Can I make MagSafe2 to MagSafe1 converter?I used the grinding method to convert a Magsafe 2 to Magsafe1, Works normally! Didn’t have a diamond dremel bit, I just used the file on a leathermen multitool. It’s not a tight fit and the plugs a little loose in the socket, but it works fine on my mid-2012 pre retina… The magnet works and the adapter stays on System report says the A.C supply’s all good. I’ve been using it to charge my older MBPRO15” consistently for a while now, Perhaps there are issues with older 2011/2010? but on a 2012 MBpro 15” no problems at all!
