Apple has made an interesting move and has made OS X Lion and Mountain Lion an absolutely free download for everyone.

You Can Now Download the Mac OS X Lion and Mac OS X Mountain Lion Installer for Free

Costing $19.99 back in the day, Apple's super old operating system for the Mac is now absolutely free. If you have a Mac which can run OS X Lion and Mountain Lion but never upgraded only because of that $19.99 fee, then today is the day you make the big jump. It won't cost you a penny.

According to Apple, these are the requirements to run OS X Lion:

Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processorOS X Snow Leopard 10.6.6 or later or OS X Lion 10.7 already installed2GB of memory7GB of available spaceSome features require an Apple ID; terms apply.Some features require a compatible Internet service provider; fees may apply

These Macs are compatible with OS X Mountain Lion:

iMac (Mid 2007-2020)MacBook (Late 2008 Aluminum, or Early 2009 or newer)MacBook Pro (Mid/Late 2007 or newer)MacBook Air (Late 2008 or newer)Mac mini (Early 2009 or newer)Mac Pro (Early 2008 or newer)Xserve (Early 2009)

For those who are new to the Mac, the operating system used to cost money to upgrade. With OS X Mavericks, Apple dropped the upgrade fee completely and has kept it that way to this day. Even the upcoming macOS Monterey update is free for users with a compatible Mac. Also, macOS used to be called OS X and before that it was Mac OS X.
