AppHalt

AppHalt is a Mac performance tool that helps you manage system resources by pausing applications you're not actively using. Rather than closing apps entirely, it temporarily suspends them, freeing up memory and processing power while keeping them ready to resume instantly. This approach is useful if you regularly work with multiple applications but find your Mac slowing down under the load. AppHalt sits in your menu bar, making it easy to pause and unpause apps without disrupting your workflow. The freemium model means you can try the basic functionality at no cost, with premium features available if you need more control or scheduling options.
