Full Disk Access

macOS hides some folders, such as Mail, Messages and Safari data, from apps unless you give them Full Disk Access. ClearMac works without it, but it can't measure or explain what it can't see, so its totals will be lower than what's really on your disk.

Turn it on

1. In ClearMac, click Open Full Disk Access Settings in the welcome screens, or Grant Access on Home. Or open System Settings yourself and go to Privacy & Security ▸ Full Disk Access.
2. Turn on ClearMac. If it isn't in the list, click +, choose ClearMac in your Applications folder, and turn it on.
3. Enter your password or use Touch ID if macOS asks.
4. Go back to ClearMac. The welcome screen notices by itself; on Home, click Recheck.

If macOS says ClearMac needs to quit and reopen, choose Quit & Reopen.

What ClearMac does with it

It reads names, sizes and dates to show what uses space. It doesn't send anything about your files anywhere, and Full Disk Access doesn't let it remove protected items: those rules still apply.

If it still says it doesn't have access

• Make sure the ClearMac in the list is the one in your Applications folder, not a copy in Downloads. Remove any extra ClearMac entries with −, then add the right one.
• Quit ClearMac completely and open it again.
• On a Mac managed by your work or school, an administrator may control this setting.

Turn it off

Turn off ClearMac in the same list at any time. ClearMac keeps working, with less of your disk visible.
