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.

New INIT 17 Virus Busted

Send Article to a Friend
Technical Support Coordinator, BAKA Computers

In a joint bulletin released today by Gene Spafford of Purdue University, the various Macintosh antiviral developers announced the discovery of a new virus earlier along with new utility versions to combat it.

The new virus, dubbed INIT 17, infects the System file and most applications as they run, and is likely to spread quickly once a machine is exposed to the virus. The virus infects programs by modifying existing code, which can in some cases cause irreparable damage to the applications or the System file. On some low-end Macs (such as the Plus, SE, and Classic) the virus can cause the computer to crash while executing infected applications.

The only overt action by the virus is to display an alert message saying "From the depths of Cyberspace" the first time you restart an infected machine after 6:06:06 PM, 31-Oct-93.

Users of Chris Johnson's freeware Gatekeeper package will be pleased to note that the current version, 1.2.7, catches INIT 17 already, so they need not update. John Norstad has released version 3.1 of his free Disinfectant utility. Jeff Shulman says registered owners of his shareware Virus Detective package will receive search strings in the mail (a good reason to register your copy!). All commercial antiviral publishers are sending updates to their subscribers and mailing notifications to registered users; contact the publisher of your utility for further information.
