If the EBA does not have an automatic update clause, you must obtain the user`s consent each time the software needs to be updated. When users install the latest version of Apple`s OS X – in this case Yosemite – they must click the “Accept” button to proceed with installation: 1.7 “Software” refers to the object code version of the product with documentation and all third-party software that the licensee may have purchased or licensed to third parties and delivered to the customer as part of the software, and all updates provided by the licensee under this agreement. End-user licensing agreements are usually lengthy and written in very specific legal language, making it more difficult for the average user to give informed consent.  When the company designs the end-user licensing agreement in such a way as to deliberately deter users from reading it and is difficult to understand, many users may not give their informed consent. Most retail software licenses reject (as far as local laws permit) any guarantee on the performance of the software and limit liability in case of damage to the purchase price of the software. One known case that confirmed such a disclaimer is Mortenson v. Timberline. A common criticism of end-user licensing contracts is that they are often far too long for users to spend time reading them carefully. In March 2012, the PayPal end-user license agreement was 36,275 words and in May 2011, the iTunes agreement was 56 pages long.
