It's normal that MacBooks Air M4 couldn't open with single hand?

Hi,

I think it's normal, though if you suppose it's not normal, try to take your MacBook Air to your local retail AppleStore, Genius Bar or Apple Authorized Service Provider to be examined your MacBook Air there.

My MBA requires both hands if only to steady it while I lift the lid, and this never struck me as unusual. I

've had many MacBooks over the years and they have all been similar.
