2 prong ungrounded power supply safe?

[kkamin]

I just bought a back-up power supply for my Macbook.

It is an official Apple Magsafe brick.

My current power supply is grounded this one is not. I'm worried about where static discharges will go when passed to the computer if there is no ground. BUT it seems weird Apple would make an unsafe power supply.

Any insight is appreciated.

Best,

Yes, it's safe. Apple has been using these adapters successfully for years, on millions of notebooks.

If it wasn't safe to use, apple wouldn't have been making it the same way for the past 10 years. It should have come with the longer extension that is grounded as well, however, the ground prong is a dummy anyway, there is not a ground prong coming out of the brick. It's the same for any laptop I have ever used.

The ground is not dummy. It is connected inside the power brick and from the cable to that metal thing that holds the plug in place.
