Security fixes for Snow Leopard as well
Accompanying the just-released OS X 10.7.4 update, Apple has also posted several new versions of other products -- including Safari, Remote Desktop, the server version of Lion's Server Admin Tools and a security update for Snow Leopard users. The Safari and Remote Desktop updates apply to both Lion and Snow Leopard, and should be available through Software Update. The Safari update is available for both Mac and Windows users.
Safari 5.1.7 adds one significant new feature in the Mac version in addition to the usual assortment of improvements and fixes: it disables versions of Adobe Flash Player that are not up-to-date. It will offer the user the opportunity to immediately download an updated version of Flash, which fixes a number of security problems. The Windows version of Safari does not offer this feature.
The new version also improves the browser's responsiveness when the system is low on memory, and fixes two issues: one that could affect websites using forms to authenticate users, and another that could prevent webpages from responding after using a "pinch to zoom" gesture. Other more minor improvements affect overall performance, stability, compatibility and security.
Safari v5.1.7 is a 45MB download for Lion, a 48MB download for Snow Leopard and a 37MB download for Windows. The program requires OS X 10.7.3 and 10.6.8 (respectively) for Macs, and XP SP2, Vista or Windows 7 for Windows.
Apple Remote Desktop client version 3.5.3 doesn't list any specific improvements apart from "general OS compatibility fixes," according to its release notes. The new version is already included in the OS X Lion 10.7.4 update but is available as a standalone update for OS X 10.6 Snow Leopard users. The file size of the update may vary on different systems, but should be around 3.8MB.
Server Admin Tools for Lion has also been updated, now at version 10.7.4 to accompany the updates for both OS X Lion client and server. The Tools kit includes the latest releases of Podcast Composer, Server Admin, Server Monitor, System Image Utility, Workgroup Manager and Xgrid Admin. All of these utilities will have been updated in the Server 10.7.4 update, but are also provided for those who use them in the client version of Lion for remote adminstration. The update is 212.4MB in size.
The tools are basically unchanged from the 10.7.3 version except that DNS Zone Data expirations can now be set to more than nine hours. Apple notes that if users have the Server Admin Tools kept outside their original locations (/Applications/Server), the update may continue to appear in Software Update even after the update has been run. It advises users to return the Server Admin Tools to the original location for correct updating and use aliases to position the apps elsewhere if desired, as well as remove any duplicate copies of Server Admin Tools.
Finally, Snow Leopard client and server users will see a Security Update 2012-002 available via Software Update (and manually downloadable here and here). The company has not yet released details of what problems the update addresses.
