MacCleaner FAQs
What is ClearDisk?
ClearDisk is a Mac OS X application designed to quickly clear your startup disk. It scans and cleans overfilled folders such as Downloads, Trash, Caches, and Temporary Files, and can also remove unused Language Resources to free up space.
How often should I clear caches and logs?
It is recommended to perform a cleanup of temporary files, including caches and logs, approximately once per month. Active internet users can accumulate several gigabytes of 'quick access memory' during this period, which can negatively impact performance if not cleared.
What happens after caches cleanup?
After a caches cleanup, you may be required to re-enter your internet passwords, though they remain stored on your hard drive. Some internet pages might also need to load twice due to specific browser-related issues.
How much space can ClearDisk free up?
ClearDisk can help you get rid of gigabytes of unneeded files. You can free up space equivalent to your Trash folder, Downloads folder, over 500 MB from Language Resources, and several gigabytes from Cache files. Regular cleaning with ClearDisk is recommended.
Does ClearDisk remove language resources from default Apple applications?
No, ClearDisk does not remove language resources from default Apple applications due to System Integrity Protection (SIP) on macOS, which prevents modifications to core system files.
How do I uninstall ClearDisk from my Mac?
To uninstall ClearDisk, open Finder, click Go → Go to Folder in the menu bar, type ~/Library, and hit Go. Within the Library folder, you can manually remove associated files. For a complete removal, using a dedicated uninstaller tool (like Nektony's own App Cleaner & Uninstaller) is often recommended.
