In any case, almost all warranty disclaimers start with "TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW" which, under consumer laws in most countries, requires the company to provide a product that can work as shown in all its advertising materials.
Which is an invalid clause in Germany and probably most other European countries. Any clause that goes beyond the extent permitted by the applicable law is automatically void in Germany. This is due to consumer protection laws. Therefore, most of these EULAs are probably void if it ever comes to law suit...
License agreements are long, the consumer laws are probably an order of magnitude bigger (and that's assuming you even know which bits are relevant)
My point is that Apple (and every other company) makes no attempt to define what their software is meant to be able to do. The license tries to wash their hands of everything that they can.
If I buy a camera and it can't take photos, it's not fit for purpose and I can return it. If I buy a computer to be able to (say) Facetime chat with my relatives, and it doesn't do that due to a bug or incompatibility, it's a murky legal quagmire whether or not I could get a refund.
