Apple has updated the EULA of iBooks Author in order to clear the air surrounding the terms by which iBooks are to be sold. Previously, the iBooks iBooks Author EULA was unclear on exactly what was restricted for sale in the iBookstore, saying that works generated through the iBooks Author app were to be sold only via the iBookstore. Now, the updated EULA specifically mentions this restriction is only applicable to iBooks in the .ibooks format, not any other format that can be generated by iBooks Author. Last week Apple released updates for both Lion and Snow Leopard, both of which had issues after release. The Lion 10.7.3 update had some weird effects with UI buttons, and was solved by downloading the combo update and re-applying that. The Snow Leopard Security Update also had issues, mostly to do with Rosetta app support. Apple has now released an updated version of the security update that fixes the issue.
Clarify for Mac is an app that's more designed for annotations and documentation, rather than anything else. It means that it's a lot like Skitch in that regard, but where Skitch is more designed for sharing, Clarify is a little more formal in that regard.
ID Software's RAGE has come to the Mac. It costs US $39.99 in the Mac App Store, and only contains the single-player campaign of the full version.
