This is not so. It's extremely rare to find a platform which
*requires* aligned access, and you certainly won't find one running OS
X. What's more common is finding a platform which *prefers* aligned
access, punishing misaligned access with significantly slower
operation. Even in those cases, "misaligned" means using an address
that isn't a multiple of your data type's size. Since char is always
one byte by definition, it is impossible to have a misaligned char
pointer.
