An Excellent Free Clipboard Manager for Mac is CopyClip
CopyClip is a free and simple clipboard manager for Mac that lives in your menu bar, storing all of the content or items that you have copied or cut into your clipboard, which you can then quickly recall and paste wherever is needed.
If you’re unfamiliar with clipboard managers, they can significantly improve your Mac productivity by storing a history of all copied content, including text, URLs/links, and even files. Unlike the default macOS clipboard, which only retains the most recent item copied or cut, a clipboard manager allows you to access many copied items and things that you have copied historically. You can then seamlessly switch between items in your clipboard for whatever task you’re doing, whether you’re writing, doing research, coding, or general computing, and extend the copy and paste feature far beyond it’s default simplicity. CopyClip is one such clipboard manager tool, which is what we’re discussing here.
