Every Mac user knows the frustration of running out of storage space, especially when the culprit is a mysterious category called “System Data.”  System Data, which was referred to as "Other" in earlier versions of macOS, can silently consume tens or even hundreds of gigabytes with no indication. Cached system files, app remnants, backups from the past, virtual machine data, and other files are common examples of these files. If you’ve ever tried to manually clean up System Data, you know how tricky it can be. 
That's where BuhoCleaner comes in - a clever and easy-to-use macOS optimization tool that does all the work for you.  BuhoCleaner's most recent version, 1.13.3, includes several impressive updates that make system data cleaning on your Mac even simpler and more efficient.  Let’s explore how BuhoCleaner helps you regain precious storage space with minimal effort.
