Wake On Demand in Snow Leopard

Putting your Mac to sleep saves power, but it also disrupts using your Mac as a file server, among other purposes. Wake on Demand in Snow Leopard works in conjunction with an Apple base station to continue announcing Bonjour services that the sleeping computer offers.

While the requirements for this feature are complex, eligible users can toggle this feature in the Energy Saver preference pane. It's labeled Wake on Network Access for computers that can be roused either via Wi-Fi or Ethernet; Wake on Ethernet Network Access or Wake on AirPort Network Access for wired- or wireless-only machines, respectively. Uncheck the box to disable this feature.

Apple Releases Various Firmware Updates

Send Article to a Friend

Apple has released firmware updates for a number of Macintosh models, including the MacBook Air (2.3 MB), MacBook (1.8 MB), MacBook Pro (3.1 MB), and iMac (1.6 MB). In each case, all Apple will admit to is that the update "fixes several issues to improve the stability" of each Mac. Otherwise, I've seen one report that the update fixes problems with the MacBook Pro's closed lid mode. Late in the week, Apple also released the MacBook Air Bluetooth Firmware Update 1.0 (1.2 MB).

It doesn't appear as though these firmware updates apply to all models of the MacBook, MacBook Pro, and iMac; the updates don't appear in Software Update and refuse to install manually on at least my MacBook and Tonya's MacBook Pro - both early versions of those models. Apple says nothing online about which models need these updates, so I recommend relying on Software Update; if a firmware update appears in Software Update, install it, but if not, don't bother trying a manual installation.

To complete the firmware update process, follow the instructions in the updater application that launches automatically after the installer finishes. And, though this should be obvious, don't do anything that could interrupt the process. If you do, you'll need a Firmware Restoration CD to restore your Mac's firmware. Apple just released Firmware Restoration CD 1.6 (30 MB), which supports the Xserve (Early 2008), MacBook (13-inch Late 2007), iMac (20-inch Mid 2007), and the iMac (24-inch Mid 2007). Previous versions of Firmware Restoration CD support other models, although it's not clear if all models are supported.
