If you close down a program while editing a particular file, that file will be opened again next time you start. This feature means applications will generally start up where they left off. ![]() It’s been implemented in other operating systems like Windows and Linux for some time now so it’s good to see Apple catching up.Īlthough there’s much in Lion that I like, one of the features I’m not sure about yet is “Resume”. This affects how OS X loads programs into memory and means attackers can no longer use exploits that assume targeted data or routines will be found at fixed locations. ![]() Lion also provides a more complete implementation of Address Space Layout Randomization (ASLR). Although the App Store on iOS has helped in keeping malware off that platform, bear in mind that the App Store is not the only way to download and install software on the Mac. Before publishing, Apps must go through an approval process that requires them to touch only those components they really need to. Sandboxing limits the kinds of interactions an App can have with other parts of the system. Under the hood, there is application sandboxing for programs distributed through the App Store. Lion also contains some interesting security features. From a user interface point of view, this includes “Launchpad”, a way of organizing and running applications with icons on a paged, full-screen interface that will be very familiar to iPhone and iPad users, and better support for full screen applications. Lion is widely seen as moving the Mac closer to the enormously successful iPhone and iPad devices. With their closely-guarded approach to release dates, Apple don’t make it easy for us to plan our efforts so I’m particularly proud of our engineering team who have kept on top things through all the preview releases. In fact, we’ve been compatible since we released version 7.3.0 in June 2011 *. ![]() ![]() I’m very pleased to announce that our currently shipping versions of Sophos Anti-Virus for Mac – both Corporate and Home editions – are compatible with Lion. Code-named “Lion”, version 10.7 is the first update to the ten-year-old operating system since Snow Leopard in 2009. After the usual protracted period of speculation and rumour, Apple finally launched the latest version of Mac OS X today.
