AltTab brings the power of Windows’s “alt-tab” window switcher to macOS.

Keeping an eye on your Mac's hardware and resource usage is helpful, but there is no accessible way to do so without third-party utilities.

Stats is an open-source app designed to help you monitor temperature, voltage, power draw, battery level, as well as general resource usage, from the menu bar. It is fully configurable, unobtrusive, and quite easy to use.

Windows users will be familiar with a feature that allows previewing window contents by hovering over their taskbar icons. If you want this in macOS as well, the only way you’re going to get it is via a third-party app.

Dock previews are DockDoor’s main functionality, with the added bonus of an alternative alt-tab feature that includes window previews. It’s an open-source app, very easy to set up and use, though still not quite perfect.
