常见问题FAQ
为什么需要「屏幕录制」权限？Why does it need Screen Recording permission?
macOS 要求所有截图工具获得这个权限才能读取屏幕内容。Snipnote 不联网，截图只会进入剪贴板，或保存到你选择保存的桌面文件里。macOS requires it for any app that captures the screen. Snipnote has no network access — your screenshots only go to the clipboard or to the Desktop when you choose to save.
按快捷键没有反应？The shortcut doesn't do anything?
可能被其他应用占用了。点菜单栏的剪刀图标 →「设置…」，换一个组合即可；和系统快捷键冲突时设置窗口会提示。Another app may be using it. Click the scissors icon → Settings… and choose a different combination; Snipnote tells you if it clashes with a system shortcut.
能开机自动启动吗？Can it launch at login?
可以，在菜单栏菜单里勾选「开机自动启动」。Yes — enable “Launch at Login” in the menu bar menu.
如何卸载？How do I uninstall it?
在菜单栏菜单里退出 Snipnote，然后把它从「应用程序」拖到废纸篓。Quit Snipnote from its menu, then drag it from Applications to the Trash.
