Marcel Bresink has released version 4.8 of TinkerTool, his system utility that lets you adjust a variety of settings under Mac OS X’s hood (covered previously by Matt Neuburg; see “Lion Frustrations? Don’t Forget TinkerTool,” 29 October 2011). While TinkerTool can still be used with Mac OS X 10.6 Snow Leopard, this update focuses on adding new ways to control system behavior in 10.7 Lion, including Launchpad and Mission Control animations, the delay when moving between Spaces and Mission Control, and the capability to open Dock Stacks by scrolling. You can also add pop-up notifications to the Dock when playing a new track in iTunes 10.4 or later, enable copy operations when previewing text files in Quick Look, and configure a less-precise edge to windows when grabbing to resize them. If you’re running a Mac OS X version prior to 10.6 Snow Leopard, TinkerTool is available in separate applications for use with those previous iterations (TinkerTool Classic for 10.1 Puma, 10.2 Jaguar, and 10.3 Panther; TinkerTool Classic Generation 2 for 10.4 Tiger and 10.5 Leopard).
