And by legacy, I mean 10-years-old or younger. My MBA that shipped with Mavericks stalled out during Internet Recovery (too much "Other" had accumulated on the drive) over the weekend. I called Apple asking for a download link so that I could reinstall my OS and get back to work (some of my work software isn't compatible with El Capitan). What baffled me was the tech support guy on the phone told me that Mavericks is considered obsolete (lol) and that unless you downloaded it during the time it was out there's no way to get it now. I told him I'd gladly pay for it, but no; it's definitely on a sever somewhere for those to download with it tied to the right Apple ID, but you're SOL if you'd like to download it now. Then I said I'd accept Yosemite until I can make a trip to the nearest Apple Store (which he said may or not not provide me with Mavericks). His answer: That's obsolete, too. And not only that, but it's also not for download/sale. But the guy did offer me a free copy of Mountain Lion. I told him my laptop isn't even compatible with that OS... What the **** is going on at Apple? I shouldn't have to resort to shady pirate sites to download a free operating system.
