My experiences are all from third-prong countries.
replyTo add to this, I notice this more frequently in the UK and EU countries than in some other parts of the world (although it varies within each country quite a bit).
replyApple avoids shipping grounded plugs as if it was personal affront to Ive. Also caused many many times for me to be shocked with electrostatic build-up.
replyall my EU/UK macbook plugs I got from apple are always grounded, metal prong and metal side pins
replyso what I mean is maybe house electricity grid is not grounded.
UK plugs are always grounded because there is no ungrounded version.
replyBut elsewhere you only get grounded plug if you buy extra extension cord for the apple power brick, otherwise it's only ungrounded.
> all my EU/UK macbook plugs I got from apple are always grounded, metal prong and metal side pins
replyThe short version, where you remove the extension with the 3-prong plug and attach the plug directly to the charger brick, is only available in 2-prong in the EU/US (the UK thankfully still gets all 3 prongs in this configuration)
yes true the short one has no grounding.
replyAnyway as I replied to the other guy (and got downvoted for it) if the plug was grounded there would be no issue. Apple chargers have ground pins.
But sure it's bad if they stopped including grounded versions by default in EU...
