We are still waiting for Apple to confirm the Mac OS X Lion release date, however in the mean time we have just come across an interesting article posted on Cnet which speaks about compatibility and is a good read if you are looking to buy Mac OS X 10.7 when it is available for download.
If you remember mid 2009 quite well you may recall that Mac OS X 10.6 Snow Leopard required a Mac which featured an Intel processor, which made it the first OS X version to not support the PowerPC architecture, this is the case with Lion, however it also requires a 64-bit CPU. The good news is that any Mac purchased brand new from 2007 onwards should be compatible, however if you bought your Mac new in 2006, or perhaps purchased a used Mac which was manufactured in this year there are a few things you need to check.
The first thing you should do is to select “About this Mac” from the Apple menu, here processor information is shown. What you are looking for is “Core Duo”, “Solo” or “PowerPC” in the processor’s name, if you see this your Mac is not compatible with OS X 10.7 Lion, however don’t get “Core Duo” and “Core 2 Duo” mixed up as the latter will support the upcoming OS X version. If you see “Xeon”, “Core i3”, “Core i5” or “Core i7” your Mac should run Lion.
If you check out Cnet’s article you can see another way of checking to see if your Mac is compatible, this requires you to go into Terminal, enter a certain command and then check your Mac version via what Terminal shows, check out this link for full details.
As you can see the baring factor is whether or not your Mac features a 64-bit CPU, however according to OSXDaily you also need at least 2GB of RAM, OS X 10.6.6 or later, at least 4GB of free disk space (more recommended) and the Mac App Store installed. For those of you who do not have the Mac App Store installed you can find out how to get this here.
You can find out all about Mac OS X 10.7 Lion here, as you can see Apple clearly state that it will arrive in July, this means that at the time of this post it is a maximum of 12 days away, however many experts suggest that it will almost certainly arrive within the week.
Is your Mac incompatible? If so, will you buy a newer model?
