The problem
A full-screen capture can bury the issue in unrelated content. A focused region and a clear annotation are easier to understand.
A practical answer
GJ File Manager provides screenshot capture and editing, followed by copy or save. macOS Screen Recording permission is required.
Step by step
- Close private material and prepare a harmless sample area.
- Use the screenshot control at the bottom of the sidebar and select the region.
- Annotate in the editor without covering the relevant detail.
- Copy or save, then check privacy and legibility before sharing.

Know the limits
System capture permission cannot be bypassed by the app. If denied, follow macOS permission guidance.
Common question
Can I change the shortcut?
Yes. Check and edit the current screenshot shortcut in Settings rather than assuming the default applies everywhere.
