Mac OS X Even though Apple has been hyping up the 64bit nature of its ucpoming Snow Leopard operating system, stating it will be the first Mac OS X release to be 64bit top-to-bottom, reality turns out to be a little bit different so far. With the current Snow Leopard seed, only Xserve users get the 64bit kernel and drivers - all other Macs default to 32bit. By holding down the '6' and '4' keys during boot, you can to boot into full 64bit mode - that is, if your Mac supports it. As it turns out, some Macs with 64bit processors cannot use the 64bit kernel because the EFI is 32bit. Note: I should have included in the article that 64bit applications will run just fine (including benefits) on a 32bit kernel in Mac OS X. Since this was already possible in Leopard, I assumed people were well aware of that. Turns out some were not, so my apologies for that.

No, it is not a good enough reason for Apple to force me into a 32-bit kernel on my Macbook, which has EFI-64. It is not a good enough reason for them to forbid me to boot into 64-bit mode if I wish to do so for whatever purpose. I understand the 32-bit default just fine, and I agree with Apple in defaulting to a 32-bit kernel for the moment. I do not, however, appreciate yet another artificial limitation Apple has decided to place upon me "for my own good."

I'm starting to think now would be a good time for me to make a clean break from Apple. The camel's back is about to break.


By all means, go and run whatever you like ―Windows, Linux, FreeBSD...

We are better off with all the whiners in another platform...
