On a Mac this step uses the Terminal app. Your technician asked you to do this and is on the call with you. Unison will never ask you to do this out of the blue.
  1. Open Terminal: press Command and Space, type Terminal, then press Return.
  2. Copy the line below, paste it into the Terminal window, then press Return.
  3. Type your Mac password when it asks, then press Return. Nothing appears on screen while you type; that is normal.
  4. Wait about a minute. It ends with the word Done.
  5. When macOS asks to let Unison Remote Support record your screen or control your computer, choose Open System Settings and turn Unison Remote Support on. Your technician will tell you which ones they need.
  6. Tell your technician. They will see your Mac appear.
What does this line do?
It downloads the Unison Remote Support agent from this site and installs it. The link in it works once and expires with your code. The agent is checked against published checksums before anything is installed.
Terminal shows an error
Read the message to your technician. If it mentions error 410, the line has already been used: your technician will give you a new code.

This line stops working once it has been used.

Step 3 of 3

Your technician will set this up with you

Nothing on this page needs to be typed or installed by you. Stay on the call.

If the download was blocked

Some antivirus products remove remote support tools automatically, even legitimate signed ones. This is common and does not mean anything is wrong.

!
Stay on the call. Do not turn off your antivirus on your own. Your technician will decide what to try next.
  1. Tell your technician what the message said, or read it out.
  2. If Windows said the file is blocked: right-click the zip, choose Properties, tick Unblock, choose OK, then extract it again.
  3. Your technician may give you a new code, because the one you used is now spent.
  4. If none of that works, they will arrange another way to reach your computer.
