    My Macbookair can cause a slight electric shock in my finger. Is it electricity leakage? Have you ever been in this situation?

    Are you using the extension cable that comes with the Macbook (grounded/earthed) or just the 2 pin? Also does this happen when the Air's running only on battery power?

    this is common on the metal machines when plugged into mains.

    my 2012 macbook pro does it.
    and my 2012 macbook air did it.
    the cure is replace the tip of charger with the earthed cable.

    I have one of these: 182.jpg

    they do them for other countries too not just UK plugs.

    Strange.... I have several laptops...

    2012 MBPr15
    2012 MBP13
    2015 MBA13
    2012 MBA11

    None of my computers mentioned above are exhibiting issues when plugged into my power adapter... this does not sound like a common issue to me...

    been several threads in here.
    Seems depend on several factors but every aluminium machine, bar my 2007 imac has given me a ever so slight tingle if lightly run fingers over case.

    Strange is all I'm saying because of all the Macs I have either owned/own or worked on, I have never experienced what you're talking about...

    maybe you have better quality earths than me then.

    i'm on the end on extension leads at home and at work the main feed to our section of building is still old vulcanised rubber cables.

    That makes me unlucky, lol.

    Considering my luck of late I probably am unlucky.
    in last 3 weeks almost been in 3 car accidents!
    Only one or cars touches and the other party drove off!

    my 2012 macbook pro using to type this gives me tingles if lightly touch case, but firm touch/holding no tingle feeling.

    also my macs are in the clip on plastic cases so maybe that has something to do with it too.

    As others have stated above, this has been discussed before. Personally, I get a not-quite-tingle when running a finger across the metal part of the case when plugged in. Doesn't matter if it's 2- or 3-prong connector - and always into a solidly grounded outlet. But it only happens when I am in bare feet, on a concrete floor (office is a converted garage). It's happened for every metal case Mac I've had.

    If you are using a non-Apple plug, I say STOP immediately. Other than that, dry environment, say less than 30% humidity can do that.
