Why can a Mac storage scan be incomplete?
macOS privacy permissions, protected system locations, cloud placeholders, encrypted data, links, and files changing during a scan can prevent any storage utility from reading every byte. Klyr Disk reports inaccessible locations instead of treating them as empty. Read how storage measurement works.
