To remotely access the macOS remote computer(s) you need to enable TCC (Transparency, Consent, and Control) for ISL AlwaysOn application on macOS.
TCC (Transparency, Consent, and Control) is a mechanism in macOS to limit and control application access to certain features, usually from a privacy perspective. This can include things such as location services, contacts, photos, microphone, camera, accessibility, full disk access and more.
You can find a "Security & Privacy" section in ISL AlwaysOn settings:
- Accessibility (to enable remote control)
- Screen Recording (to enable screen view)
- Disk Access (to enables file transfer)
If the status for these Settings is DISABLED, ISL AlwaysOn does not have a consent to either remote control the computer, view the screen or to transfer files with remote computer.
Enable Remote Access on macOS
Open "Settings" in ISL AlwaysOn.
Click "Change" button in the "Security & Privacy" section next to the permission that you'd like to enable.
Click "Open System Preferences" button.
In the Security & Privacy window click "the lock" icon in order to make changes.
Enter the macOS password and click "Unlock" button.
Click "the checkbox" next to the ISL AlwaysOn application. Repeat this step also for Screen recording and Full Disk Access.
If all the needed permissions were enabled correctly the state of Security & Privacy in ISL AlwaysOn settings will change to ENABLED.
