AN EASIER WAY TO TINKER
Want access to even more hidden preferences and behaviors in macOS? TinkerTool (free, bresink.com) gives access to a huge range of them in familiar-looking preference panes, without you using the Terminal.
You can simply click a checkbox to turn on each of the tweaks we’ve covered here. Among the many things it can change, our favorites include: eliminating the brief pause before the Dock (when hidden) slides into view; disabling the Dock’s animation so it pops up/hides instantly; stopping the Help window sitting on top of all others; and removing the delay between dragging a window to a screen edge and jumping to the next space.
