When TeamViewer tries to access one of these folders for the first time during a file transfer, macOS displays a prompt, asking for your permission to access the folder. This prompt is displayed on the remote Mac and blocks the app until the prompt is confirmed or denied.</p><p>To avoid situations where TeamViewer is unresponsive and unable to access the remote filesystem, with no one in front of the remote Mac able to confirm the macOS permission prompt(s), file transfers outside of remote control sessions require Full Disk Access permissions.</p><p><br></p><h3 data-id="-1"></h3><h2 data-id="required-permissions-for-file-transfer">Required permissions for file transfer</h2><p>Which permissions are required depends on how you are using file transfer: Standalone or during a remote control session.</p><p><strong>Standalone file transfer</strong> (without a remote control session) requires <strong>Full Disk Access</strong> for the TeamViewer app.</p><p><strong>File transfer during a remote control session</strong> requires</p><ul><li><strong>Full Disk Access</strong> or</li><li><strong>Accessibility</strong> and <strong>Screen Recording</strong> permissions.</li></ul><p>All permissions can be configured <strong>on the remote Mac</strong> through <strong>Help</strong> --> <strong>Check System Access</strong> in TeamViewer.
