Let Me Solo IT on macOS

Let Me Solo IT listens to two sources: your microphone, for your own voice, and the sound your Mac plays, for the other participants' voices. macOS asks for your permission for each:

• Microphone: to hear your voice. The app asks at startup, so the macOS prompt never appears for the first time in the middle of a call.
• Screen Recording: to hear the other participants. macOS gives the sound your Mac plays only to apps with this permission. It also lets you send screenshots with a question.

Nothing else needs to be installed. The app carries only an ad hoc signature, so macOS treats every update as a new app: after each update, both permissions have to be allowed again, as described below.

The first time you open a new version downloaded with your browser, macOS checks it before it starts. This takes about 3 minutes, and nothing appears on screen while it runs.

• Don't open the app again and don't force-quit it while you wait: opening it again is what makes macOS say the app “is not responding”.
• When macOS says it cannot verify the app, click Done, open System Settings, then Privacy & SecuritySystem Settings›Privacy & Security, click Open Anyway and confirm.
• This happens once for each new version; later starts take a few seconds. The install command from the download section skips the long check.

• While Screen Recording is missing, the app's Review app permissions card at startup shows Grant on its row (Settings, then Advanced, then Screen capture, then Review permissionsSettings›Advanced›Screen capture›Review permissions opens the card again), and so does the “Participants' voice is not captured” warning. Click it: macOS shows its prompt or opens System Settings at the list below. After an update, Grant first removes the previous version's entry. Allow Let Me Solo IT; if it is not in the list, click the + button, choose Let Me Solo IT from Applications and turn it on.
• Quit and reopen the app. macOS applies Screen Recording only after the app restarts: until then the app may hear the call but take no screenshots, or the reverse.

If no prompt appears, or nothing changes after an update

After an update, the switch in the list may still look on, but it belonged to the previous version and no longer counts. Turning it off and on does not help. Instead:

1. Open System Settings, then Privacy & Security, then Screen & System Audio RecordingSystem Settings›Privacy & Security›Screen & System Audio Recording (called Screen Recording on macOS 13 and 14). The app's Open Settings link opens this page.
2. Select Let Me Solo IT in the list and remove it with the minus button.
3. Allow it again: click the + button, choose Let Me Solo IT from Applications and turn it on. (Grant in the app does the removal for you and opens this list.)
4. Quit and reopen the app.

The app shows this warning when it cannot hear the sound your Mac plays, and names the reason after it. Most often Screen Recording is missing, or it was allowed for the previous version before an update:

• Click Grant on the warning, then allow Let Me Solo IT as described above.
• Check Let Me Solo IT in System Settings, then Privacy & Security, then Screen & System Audio RecordingSystem Settings›Privacy & Security›Screen & System Audio Recording (Screen Recording on macOS 13 and 14). If it is on but the app was updated, remove it and allow it again, as in If no prompt appears.
• Quit the app completely and open it again.

“This needs macOS 13 or later”

The app hears the call's sound through a part of macOS that came with macOS 13. Update your Mac in System Settings, then General, then Software UpdateSystem Settings›General›Software Update, then open the app again.

“This copy of the app is missing a part”

Part of the app did not install. Download the app again from this website, replace the copy in Applications with it, and open it again.

“macOS stopped capturing the call's sound”

Quit the app and open it again. If the warning comes back, follow Grant Screen Recording: remove Let Me Solo IT from the list, allow it again, and restart the app.

When the microphone gives no sound at all, the app's status light shows a flat amber line, with the tooltip “No sound at all from the microphone: check the Microphone permission and the input device”.

• Check Let Me Solo IT in System Settings, then Privacy & Security, then MicrophoneSystem Settings›Privacy & Security›Microphone. After an update, macOS usually asks again; if the switch looks on and the app still hears nothing, select Let Me Solo IT, remove it with the minus button, allow it again when the app asks, then quit and reopen the app.
• Check the input device in Settings, then Advanced, then AudioSettings›Advanced›Audio (see Microphone and speaker). A saved microphone that is not connected when listening starts is replaced by the system default for that run.

More help for every system is in the guide's Troubleshooting.

If you start Let Me Solo IT from a source checkout in Terminal, macOS gives the permissions to the app that launched it, Terminal (or the Python that runs it), not to Let Me Solo IT. Allow Screen Recording and Microphone for Terminal in the same lists, then quit and reopen Terminal.
