Mac OS X Services in Snow Leopard

Mac OS X Services let one application supply its powers to another; for example, a Grab service helps TextEdit paste a screenshot into a document. Most users either don't know that Services exist, because they're in an obscure hierarchical menu (ApplicationName > Services), or they mostly don't use them because there are so many of them.

Snow Leopard makes it easier for the uninitiated to utilize this feature; only services appropriate to the current context appear. And in addition to the hierarchical menu, services are discoverable as custom contextual menu items - Control-click in a TextEdit document to access the Grab service, for instance.

In addition, the revamped Keyboard preference pane lets you manage services for the first time ever. You can enable and disable them, and even change their keyboard shortcuts.

Gatekeeper 1.2.7

Send Article to a Friend

Gatekeeper 1.2.7 is a set of Macintosh system extensions (INITs) and related control panels (cdevs) that, when active (i.e. allowed to install themselves during the boot process), offer protection against attacks by all viruses known to the author at the time of this release.

Gatekeeper also monitors computer activities for what are considered to be suspicious 'events' or 'operations,' in an attempt to intercept what could be variants of known viruses or even completely new viruses.

Since its initial release in January of 1989, Gatekeeper has repeatedly demonstrated its ability to stop the spread of viruses which were unknown during its design. Like any anti-virus system, however, it cannot guarantee complete protection.

Of course, no claims or promises are made regarding Gatekeeper's effectiveness or suitability, and some functions and capabilities of Gatekeeper are non-trivial to use and may require a careful reading of the documentation.

Version 1.2.7 enhances the capabilities of, and corrects bugs in, version 1.2.6. Gatekeeper 1.2.7 is archived at <sumex-aim.stanford.edu> as /info-mac/virus/gatekeeper-127.hqx.

[Recent discussions on the Internet indicate that the previous version of Gatekeeper and AutoDoubler 2.0 from Fifth Generation Systems tended not to agree on various matters. We use John Norstad's excellent and unobtrusive Disinfectant, but early reports indicate that Chris fixed some of the conflicts between the two. -Adam]
