Maybe it should see a doctor?

Or a "clinic" possibly lol...looks like this apple was sleeping around a bit and not being "safe"

Sorry, but I have no idea what could have caused that.

Just did a google search and looks like it could be apple scab...

If scab, the surface is dark-colored, rough and corky and may split. Yours is different.

It's a tasty mutant...I guess they been dumping radioactive waste below you ;)
Also, find a "Macro" mode on your camera, this will help focus on close up objects instead of the foreground.

I get them on my Golden Dorset as well.

Looks a little like PC scars.

Thanks guys for your help and humor! lol.

I saw the very same bumps on some of Stephen Hayes' apples on his youtube channel. He's over in England and has some kind of beetle taking bites out of his apples when they're young. Those that survive form those bumps.

I think its caused by a thrip like pest in the blossom.
