It’s in regards to the update to Mac OS X Lion, scheduled for the first weeks of July …. You can see the list of hardware compatible with this update .
But so what about the software, if you have questions about an application you use Mac much, RoaringApps can help you with a list of compatible applications Lion.
It is based on actual tests with the new OS and you can through the list you can see an icon that will show if supported, if it has been tested and not working properly, or if you have not tried.
You can also check from your browser application to check a particular application.
See the compatibility list from roaringapps website.
This page is highly recommended because they usually use a few applications are permanently on your Mac and it is good to consider if you have them … in my case I use Coda and at least the first betas of Mac OS X Lion yet was compatible.
