If Apple releases Mountain Lion on the same schedule they released Lion last year, they will unleash the latest version of OS X to the world the day after their quarterly earnings call. That means that next Wednesday, July 25th, everyone should be able to drop $20 on the Mac App Store for a copy of OS X Mountain Lion.
There’s one exception though: if you bought a Mac after June 11th, 2012, you’ll be automatically eligible to receive a free OS X Mountain Lion upgrade. That means if you’re the proud owner of a new Retina MacBook Pro, MacBook Air or 2012 MacBook Pro, or any older Mac purchased recently, you’ll get a free upgrade.
All you have to do is go to this page within 30 days of when Mountain Lion drops and tell Apple you’re eligible for an upgrade. Generous, no?
