OS X Mavericks is free, yes. But please look before you leap !

First and foremost, ensure that your Mac is compatible. You’ll want to have enough RAM (not just the minimum 2 GB, far better to go with more if you can), and ideally (we recomend) at least a 7200 RPM hard drive, better still – ideally – an SSD drive for the best responsiveness.

The listed requirements are as follows (see http://www.apple.com/osx/specs/ ):
OS X v10.6.8 or later, 2GB of memory , 8GB of available space
You’ll need an Apple ID if you don’t already have one (and you probably do if you’re using iTunes), see

The compatible hardware/model list is:
iMac (Mid 2007 or newer)
MacBook (Late 2008 Aluminum, or Early 2009 or newer)
MacBook Pro (Mid/Late 2007 or newer)
Xserve (Early 2009)”

Please – whatever you do – make sure you have a known-good, full backup (via Time Machine or your other backup method of choice) before you do anything.

It’s a good idea to read a little more about it, and Macworld has a great writeup here:

iOS 7 – what you need to know

If you have an Apple iOS device that didn’t come with iOS 7, and you’re considering the update, there are some things you should keep in mind before taking the leap:

It is not possible to undo this update.

Ensure that iOS 7 is permitted for use at work if you do use it in that capacity at all. If your workplace IT has’t tested and approved it for use, and you really do need it for work purposes – even if it’s “just email” – then I recommend you don’t take the risk because you’ll be on your own if  you find out after the fact that there’s a problem.

Keep in mind that iOS 6 has obtained FIPS 140-2 validation, iOS 7 has not – not yet, and it could take some time.
If this is a requirement for you, stop now and wait.

If you do go ahead: Backup your device via iTunes first.
I also recommend that you do a full power-cycle of the device prior to applying the update. Hold down the power button until a message and the slider for doing a full shutdown appears. Wait a few seconds and then use the power button to turn it back on.

There are a great many changes and some new features in iOS 7, I recommend having a read at

I’m using iOS 7 without issue and so far enjoying it very much !
