List of Applications not compatible / Not working with the Mac OS X Lion

OS X Lion is here and  every Mac user is excited about it, $30 price tag will sure not stop the users from upgrading your Mac. But before that, is your Mac compatible enough for OS X Lion is a HUGE question concerning people?

We have posted an article the features of Mac OS X Lion.

Some applications that are compatible with Mac OS X 10.6 “Snow Leopard” and earlier versions of Mac OS X are not compatible with Mac OS X 10.7 “Lion”.

Although incompatible Mac OS X applications are not limited exclusively to those written for PowerPC processors, perhaps most notably, Mac OS X Lion does not support the “Rosetta” translation engine. As a result,  no PowerPC Mac OS X applications will operate on Mac OS X Lion.

Before deciding whether or not to upgrade a particular Mac, one will need to upgrade, replace, or discard incompatible applications or  run the risk of “entombing” data in formats that can no longer be accessed on that computer.

This is most likely to be an issue for “old school” — or at least middle school — Mac users who have Mac OS X applications that have not been upgraded to Universal or Intel versions. There are hundreds, if not thousands, of PowerPC Mac OS X applications that one could have installed and running smoothly on a Mac OS X Snow Leopard system that will not be able to make the leap to Lion.

Hardware Compatibility

Apple specifies that your Mac must have an Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor to run Lion and not anything lower than this. If you’ve purchased your Mac in 2006 or later, then you’re good to go. Also, a minimum of 2GB RAM and at least 4GB of additional disk space is a pre-requisite.

Just because Apple specifies that Core 2 Duo systems may not require any upgrades, it doesn’t mean that Lion will run all that well. It’s advised to have the latest processor, but you can still give it a shot.


Make sure your Mac is running Snow Leopard 10.6 or higher version and has the Mac App Store app installed. If you’re running OS X 10.5 Leopard or anything less, then it’s time to upgrade to

Snow  Leopard first. Snow Leopard is available for $29 (plus shipping) at the online  Apple Store.  The reason why you need to upgrade is because OS X Snow Leopard was the first version of OS X to support the Mac App Store, so it becomes a 2 step process

What software will not work with Mac OS X Lion

Make sure that your third party applications that are installed are upgraded to their latest version. Sometimes, these third party applications may not work properly with Lion. Thankfully, most app developers are working on their apps to make sure they’re ready for Lion, so a software update may fix the issue. Frequently visit the developer’s website  to see if the developer’s have updated anything about Lion compatibility.
