Stay In Control Mac OS
With the release of Mac OS 10.14 (Mojave), Apple introduced new security requirements for all remote support solutions, including Take Control. When the new Accessibility and Full Disk Access security requirements are enabled you can take control of the remote device and interact with its files, otherwise you can only observe when connected. Mac OS 10.15 (Catalina) expanded these security settings by introducing a Screen Recording permission. After configuring the Privacy settings, the computer then becomes controllable and accessible using the selected remote control solutions.

This makes Voice Control a much better dictation system than the Enhanced Dictation Apple provided in previous editions of Mac OS/macOS. Voice Control is disabled by default.

Only a user with administrator rights on the remote computer can configure these Privacy & Security settings. These security settings cannot be configured remotely.
After applying these settings, Take Control will be able to control the computer remotely. Where these settings were applied during an active session and you experience control problems, close the Take Control session and then reconnect to the Mac.
Set up access during the first Take Control connection

The first time you initiate the Take Control connection to the remote Mac running Mac OS 10.14, an Accessibility Access (Events) dialog displays. If the remote Mac is running Mac OS 10.15 and later, a Screen Recording dialog also displays. The dialogs only display one time per application during the first connection attempt, even if the application is uninstalled then reinstalled.

What to do if the Full Disk Access dialog displays
The user on the remote Mac may see this dialog display when Take Control attempts to interact with files on that Mac, for example during a file transfer. To allow this Take Control interaction, work with the user who has administrator rights on that remote Mac to complete the following steps in the Full Disk Access dialog:
- Click Open System Preferences.

How to grant access when the dialogs do not display
Where the Accessibility Access (Events), Screen Recording, or Full Disk Access dialogs did not appear, or if the Mac administrator user wants to change their selected options (for example accidentally selected Deny instead of Allow), they can configure the setting directly.
- Navigate to System Preferences > Security & Privacy > Privacy, then select Accessibility Access (Events), Screen Recording, or Full Disk Access.
- Click the padlock in the lower left corner to unlock and allow changes.
- Enter the computer's administrative account credentials.
- Select the Take Control check box.
- If Take Control does not display but is installed on the computer:
- Click + below the main window.
- Navigate to the Applications folder (use Finder if needed).
- Select Take Control.
- Click Open.
- Take Control should now appear in the main window for selection.
- Close the Security & Privacy window.
Using screen as a serial terminal on Mac OS X
Geek Inc.If you develop on an Apple and find yourself doing any sort of device or embedded development, you will quickly find the need for a serial terminal on Mac. There are a few software apps out there, but I find it much simpler to simply use the terminal application “screen”.
This works well particularly if you have an RS-232 serial to USB converter.
The first thing to do is determine which device you want to connect to.
Once you’ve determined which device you would like to use, you can execute the SCREEN command to start the serial terminal session on your Mac. Remember to specify the speed (baud rate) after the device name.

Once you’ve connected, you can use the terminal as you normally would.
To exit (and close the screen gracefully) press:

Screen will then prompt you to quit and kill all of your windows. Press “y” and you’ll be back to your shell terminal.
This method works equally well if you want to connect to a serial bluetooth device. You must simply make sure that the bluetooth device is paired and active. Then you will be able to see the device in the list of devices. Once you’ve connected to the serial bluetooth device with screen, the connection will be held active for the length of your session.
I’ve used this method to connect to the sparkfun Bluetooth Mate Gold. It simply appears as a serial stream that you can communicate with exactly as you would with any other serial device.
