A few days ago, the Mac community was up in arms after a security researcher, David Emery, announced that he had found a flaw in Mac OS X 10.7.3 (Lion) that allowed a computer running the OS to store user passwords in cleartext. The flaw had actually been found in February by a user named tarwinatorn, who posted word of the issue on Apple"s support forums but no one seemed to notice it at the time.
The issue affected a Mac PC if it used FileVault encryption in Mac OS X 10.6 (Snow Leopard) and then upgraded to the current Lion version. People who own a Mac PC that had Lion pre-installed were not affected by this flaw.
Now AppleInsider reports that Apple has released a new update to Lion, which brings the version number up to Mac OS X 10.7.4. The update reportedly fixes this FileVault password issue.
In addition to that problem being solved, the new 10.7.4 update has a number of other bug fixes and improvements, including one where the "Reopen windows when logging back in" setting is always checked off. The patch also improves compatibly with some British made third-party USB keyboards and improves the Internet sharing of PPPoE connections
The new patch also contains the new version (5.1.6) of Apple"s in-house Safari web browser, which brings some "stability improvements" to its users.
