with the quotation fixed...

I have boxed copies of 10.{1,2,3,4,5} at home. Never once have I signed any agreement or acknowledgement or waiver of rights.

Without a licence, or a statutory right, you have no right to install the software on a piece of hardware - that requires copying, which, in respect of a copyrighted work, is an act restricted by copyright. So, you either accept the licence which comes with the software, and have the right to install the software under the terms which Apple provides, or else you do not accept the licence, and your installation of the software (or any performance of an act restricted by copyright) infringes Apple's copyright. You do not need to sign anything to get a licence, but, equally, you do not need to waive anything to infringe Apple's copyright.
