CleanMyMac by MacPaw has published its Q2 2026 macOS Report, “Five Findings From One Million Macs,” drawn from anonymized data across more than one million Macs between April and June 2026. One finding stands out: Mac users cleared 46 petabytes of invisible data in a single quarter, files created by the system and apps rather than anything users chose to keep. A few more findings:Temporary system data alone made up nearly 6 petabytes of that total. Users removed 26.5 million forgotten or duplicate files over the quarter. Almost all our income is from Patreon support and sponsored posts.
