OS X originally only cared about the first 8 characters of the password, everything after that is allowed but ignored. I haven't seen any notes about this changing.

That hasn't been true for years now. As for the maximum I have no idea.

There is no maximum in the system per se - you can enter the entire text of Moby Dick if you want to - but I suspect that the the change password dialog box has some sort of upper limit, and you don't add any more entropy after 64.

The new Mac Pro has up to 30 MB of cache inside the processor itself. That's more than the HD in my first Mac. Somehow I'm still running out of space.

It's odd that it mentions "Products Affected: Mac OS X 10.0".

Mac OS X Mountain Lion currently stores passwords using a SHA-512 hash with a 32 bit salt. The initial versions indeed used DES (which ignores anything beyond chars), but the last one to do that was 10.2. 10.3 had a freaky way of getting in by only using the first 14 chars (because Apple wanted compatibility with Windows and had not implemented NTLM authorization, they also stored a LANMAN hash, which is limited to 14 chars) but not for the main login window, and that hole has also been closed for a long time now.
