The fine folks at CleanMyMac have just released a comprehensive ebook on how to speed up slower Macs. It’s got recommendations on how to identify the biggest culprits that slow Macs down, how to clean every corner of macOS, and how to retrieve RAM. They’ve also included some lesser-known Mac productivity hacks such as renaming files in bulk or turning folder icons into emojis to set the right mood. It does happen to mention CleanMyMac as a solution to some of the problems, but it also includes lots of helpful commands and actions that don’t require using additional software. Best of all, it’s free.
