Don’t forget – If you purchased a new Mac between June 6th and today, you are eligible for a free upgrade to Mac OS X Lion! Apple’s Lion Up-To-Date program is now live, and I have redeemed a code myself, so I can assure you that it works!
From Apple’s original press release in June:
The Mac OS X Lion Up-To-Date upgrade is available at no additional charge via the Mac App Store to all customers who purchased a qualifying new Mac system from Apple or an Apple Authorized Reseller on or after June 6, 2011. Users must request their Up-To-Date upgrade within 30 days of purchase of their Mac computer. Customers who purchase a qualifying Mac between June 6, 2011 and the date when Lion is available in the Mac App Store will have 30 days from Lion’s official release date to make a request.
The free upgrade comes in the form of a Mac App Store redemption code that will allow you to download and install OS X Lion onto all your registered Macs through the official channel. Don’t forget – this is a great way to save $30!
To apply, just visit http://www.apple.com/macosx/uptodate/, click the appropriate redeem link, enter your serial number and when/where you bought the machine, and presto – you have your redemption code! They even automatically email it to you!
They also have an up-to-date program for Lion Server under the same terms.
