Marcel Bresink has released TinkerTool 4.95, a small update to his under-the-hood customization system utility. The app now offers a setting that enables the debug menu of Disk Utility and the App Store application in Mac OS X 10.7 Lion or later. For 10.8 Mountain Lion users, the release adds settings to control smoothing and to disable the default behavior of asking if you want to save new documents to iCloud in supported apps (such as iWork, TextEdit, and Preview). It also adds a pane to control Resume behavior for individual applications in Mountain Lion. (Free, 3.9 MB, release notes)
Viewing Wi-Fi Details in Snow Leopard
In Snow Leopard, hold down the Option key before clicking the AirPort menu. Doing so reveals additional technical details including which standards, speeds, and frequencies you're using to connect, as well as what's in use by other networks. With the Option key held down and with a network already joined, the AirPort menu reveals seven pieces of information: the PHY Mode, the MAC (Media Access Control) address, the channel and band in use, the security method that's in use, the RSSI (Received Signal Strength Indication) measurement, the transmit rate, and the MCS Index. In Leopard, some, but not all, of these details are revealed by Option-clicking the AirPort menu.
