7 Ways to Free Up Disk Space on Mac
macOS slows down when disk space runs out. These 7 methods, with help from OptiClear, let you reclaim storage without risking important files.
1–3: Quick wins
Empty the Trash, clear browser caches in OptiClear, and delete old system logs. These three steps are quick and low-risk.
4–5: Medium wins — large files and duplicates
Use OptiClear's Disk Map to spot your largest folders, then sort Downloads by size. Remove duplicate files with the Duplicate Finder.
6–7: Big wins — Xcode and old apps
Xcode's DerivedData and simulator runtimes can grow very large. Uninstall apps you haven't opened in months; OptiClear removes their leftover files together with the app so no orphan files remain.
