Apple has released Safari 5.1.2 for Mac OS X 10.7 Lion and 10.6 Snow Leopard. The minor version bump reflects the fact that the updated Web browser introduces no major functionality, but rather addresses a number of issues related to memory usage, where it should now be more conservative, and application stability, along with a fix for a bug that could cause Web pages to flash white. Safari also now supports display of PDF files embedded directly inside a Web page. (Free update via Software Update, 38.7 MB Lion/47.1 MB Snow Leopard)
Full Screen Quick Look in Snow Leopard
When viewing files in the Finder in Snow Leopard, instead of pressing just the Space bar to enter Quick Look, press Option-Space to display the selected document in full-screen Quick Look, expanding the preview and hiding everything else that would otherwise remain visible.
Air Display 2 lets you use your iPad, iPhone, or nearby Mac as
extra screen real estate for your main computer. Now smarter,
better, and 50 percent faster. <http://avatron.com/tidbits>
