Yes, the issue isn't actually the bootstrap. It is the fact that the actual .app was packaged with the old Apple Java 1.6. It isn't compatible with the new 1.7 or 1.8 java made by Oracle because Apple wanted to keep a hold on things. So really, the .app has to be repackaged.
Definitely confirmed.
Sorry, I had particles on minimal. But, even if particles are on minimal, shouldn't SOME particles show?
Thanks for checking.
I get this issue too, but it is whenever they take damage, not just when they are killed. Instead of going red, they go white.

Remember, this isn't Apple's problem. This is to do with Mojang and the way Minecraft.app is packaged.
