Adobe has updated Acrobat XI and Reader XI to version 11.0.02 solely to improve the security of the two apps. The updates address critical vulnerabilities in versions 11.0.01 and earlier, vulnerabilities that could enable an attacker to take control of your system (detailed over at The Next Web). The update for Acrobat XI is just 11.9 MB; meanwhile you can choose between the delta updater (25 MB) or the full installer (76.6 MB) for Reader XI. Additionally, Adobe recommends that users of older editions of Acrobat and Reader update their software as well, with Acrobat getting version 10.1.6 (13.5 MB) and version 9.5.4 (10.8 MB). If you can’t update to Reader XI 11.0.02, you can similarly choose version 10.1.6 (17 MB) and version 9.5.4 (5.4 MB for Intel, 5.6 MB for PowerPC). ($449 new for Acrobat XI Pro, free updates)
Extend Mac OS X's Screenshots
Mac OS X has a variety of built in screenshot methods. Here's a look at a few that offer more versatility than the basic full-screen capture (Command-Shift-3):
• Press Command-Shift-4 and you'll get a crosshair cursor with which you can drag to select and capture a certain area of the screen.
• Press Command-Shift-4-Space to select the entire window that the cursor is over, clicking on the window will then capture it. The resulting screenshot will even get a nice drop shadow.
• Hold down the Space bar after dragging out a selection window to move your selection rectangle around on the screen.
• Hold down Shift after dragging out a selection to constrain the selection in either horizontal or vertical orientation, depending on the direction of your drag.
• Hold down Option after dragging out a selection to expand the selection window around a center point.
