it is possible to use my new MagSafe2 with old macbook pro (old magsafe on it)? i cannot find any adapter.
They'll continue to sell chargers for older models for quite some time, if something ever happens to yours.So basically I'll Ned to keep older charger for my old MacBook pro
Very interesting. I wonder why they did that? Maybe to lower the current (amps) under full load because the smaller connector pins can't carry as much current? Probably also means that the older 85 watt adapter with "MagSafe to MagSafe 2 converter" won't supply all 85 watts and will take longer to charge.Magsafe 2 runs at 20v; magsafe runs at 16.5v (and the macbook air magsafe actually ran at 14.5v).
Right. Well, the system may be able to handle 20v without failing, but Apple won't make an adapter (and will cite the voltage difference as the reason if pressed on the issue).That bites. My old cable is shot to pieces and i was hoping to buy a second MagSafe 2 adapter to use with both systems. If there is any news on this please update. Am I right in saying that an adapter converting down to the MageSafe 1 is not possible in terms of voltage?
I already purchased an extra Magsafe 2Right. Well, the system may be able to handle 20v without failing, but Apple won't make an adapter (and will cite the voltage difference as the reason if pressed on the issue).
Why not get an 85w MagSafe 1 and an adaptor and use that with both systems?
Throughout the whole of Europe and in many other parts of the world, there is a thing called the "must fit" exemption to patent and design rights which protects the market for spare parts and ensures a competitive market. Any aspect of a design cannot be protected where it is to allow a mechanical connection or for one product to fit with another product in order for the original product to perform its function. This is why you can go down the road and buy an OEM fender for your car. As the Magsafe connector would simply be converting MAgsafe 2 to Magsafe 1 so that you can use a Magsafe charger on your laptop, there would be no available action by Apple. (Similarly there would be no available action if someone provided a Magsafe converter allowing a Magsafe to charge a windows machine.Since Apple will not license the MagSafe connector how do you figure that it will be a Kickstarter project?
You can find a YOUTUBE which shows you how to fix the cable without buying a new power brick.That bites.

No, it is safe, but the MagSafe 2 power supply might not like the "MagSafe 1 era" load to which it is connected. I tried this: I ground a MagSafe 2 bit to turn it into a MagSafe Intersection bit. (I removed too much material, and melted central plastic which covers pogo pin assembly, with an electric motorised grinder. Probably, I would have done a better, much slower, job with a file.) I tried using 85W and 60W MagSafe 2 Power Adapters with MacBookPro6,1 and MacBookPro7,1 (respectively, 17-inch and 13-inch, both Mid 2010). My 60W A1435 Power Adapter works, and my 85W A1424 does not work, with test subject 2010 MacBooks Pro.Would it kill the macbook if one simply filed down the edges on the MagSafe 2?
