In regards to the copywrite material...
Copywrite laws are just that. The prevention of duplication for any reason, without the expressed written concent of the owner of the copywrite.
Now, that being said, as long as you or anyone else does not make money off the use of the Apple logo, then you can use it. But the use of the terms "make money" is very specific.
If there is any money indirectly or directly made from this product or a product associated with it, you'll be hearing from Apple's lawyers.
A friend of mine got into trouble from Nike over this very subject.
He was producing, of all things, t-shirts. He had developed a whole theme of shirts that he was making himself. One of the t-shirts he wore was a self-made Nike shirt. He Didn't sell this shirt, but he had it up as a display net to shirts he did sell.
The idea behind the display was for customers to guess which one was original Nike shirt and what one was made by his company. The way the display and related advertisment was designed, it actually highlighted the Nike logo and shirt design (which was just a black Nike logo on a white shirt).
Nike didn't see it that way, they sued him and won.
Apple is no different than any other company when it comes to protecting it's image. Simply put, they don't want anyone making money off their image - for any reason.
If you're really serious about doing this t-shirt thing, please consider the trouble you could get yourself into if your product becomes really popular.
You have to make an attempt at changing the content of the logo...Or you have to get Apple's concent to use their logo. Don't avoid the issue and just expect Apple to understand, deal with it now so you can move forward and create great t-shirts for everyone to enjoy.
