How long does it take Apple to ship their product with their latest software update once they release it to the public? All the rumors as of now point to the release date of July 25th for Mountain Lion to be available for download. I am looking to buy a MacBook Pro during the first week of August, but I want to wait until Apple ships their computers with Mountain Lion already installed on it. I know that even if I bought a computer today, I would be eligible for a free copy of Mountain Lion, however I would prefer to buy the computer with Mountain Lion already installed so there are no issues for drivers, software, etc. I am interested in buying from an Apple retail store, not Apple.com. What is your say on this?
