Dejal has released Simon 3.6 with improved compatibility with OS X 10.9 Mavericks, plus new Notification Center and History plug-ins. Additionally, the system-monitoring tool brings a rewritten Twitter plug-in (along with a Twitter Update default notifier) that works with the latest Twitter API and uses Internet Accounts from System Preferences so you don’t need to enter your Twitter credentials in Simon. The update also adds support for escaping braces (curly brackets), square brackets, and custom date/time formats in report templates, adds a MySQL default service, and considers the check frequencies for successes and failures when calculating the Up Time percentages. A quick 3.6.1 release fixes a few minor bugs. ($49–$499 new, free update, 12 MB, release notes)
Smarter Parental Controls
If you've been using the parental controls options in Mac OS X to lock your child out of using a particular computer late at night, but would like to employ a more clever technique to limit Internet access, turn to MAC address filtering on an Apple base station.
To do this, launch AirPort Utility, select your base station, and click Manual Setup. In the Access Control view, choose Time Access to turn on MAC filtering. You'll need to enter the MAC address of the particular computer, which (in 10.5 Leopard and 10.6 Snow Leopard) you can find in the Network System Preferences pane: click AirPort in the adapter list, and click Advanced. The AirPort ID is the MAC address.
