Solution -run a script to remove leftover Sophos Home files 

The uninstall script for Mac targets and removes several Sophos Home related entries from your system and must be executed as Administrator. 
These steps should only be performed by advanced users.  

Creating the script:


Video steps available here: macOS - Sophos Home uninstall script for advanced users 

1. Click on the magnifying glass at the top right of the screen to open Spotlight Search
2. Type "TextEdit" , hit Enter
3. Start a New Document (this opens a blank text file)
4. At the top  of your screen select Format---> "Make plain text" to convert the file to txt
5. Copy-paste the following into the text file:
   
   

   #!/bin/bash
   echo "Remove Sophos Home"
   sudo pkill -9 "Sophos*"
   sudo rm -r /Library/Sophos\ Anti-Virus
   sudo rm -r /Library/LaunchDaemons/com.sophos.*
   sudo rm -r /Library/LaunchAgents/com.sophos.*
   sudo rm -r /Library/Preferences/com.sophos.*
   sudo rm -r /Library/Logs/Sophos\ Anti-Virus.log
   sudo rm -r ~/Library/Logs/Sophos\ Anti-Virus/Scans/
   sudo rm -r /Library/Application\ Support/Sophos/
   sudo rm -r /Applications/Sophos
   sudo rm -r /Applications/Sophos\ Anti-Virus.app
   sudo rm -r /Applications/Sophos\ Home.app
   sudo rm -r /Applications/Remove\ Sophos\ Anti-Virus.app/
   sudo rm -r /Applications/Remove\ Sophos\ Home.app/
   sudo rm -r /Library/SophosCBR
   sudo rm -r /var/db/receipts/com.sophos.*
   sudo rm -r /Library/Extensions/Sophos*
   sudo rm -r /Library/Frameworks/SAVI-pyexec.framework 
   sudo rm -r /Library/Frameworks/SAVI.framework 
   sudo rm -r /Library/Frameworks/SophosGenericsCommon.framework
   sudo rm -r /Library/Frameworks/SophosGenericsCore.framework

6. Click on the "X" at the top left to close TextEdit and save the file
7. Name it "UninstallScript"  and save it to your Desktop
8. The file name displayed on the Desktop should be: UninstallScript.txt
   
   

Making the script executable and running it:

1. Click on the magnifying glass at the top right of the screen to open Spotlight Search
2. Type "Terminal", hit Enter
3. Type the following commands (hitting "Tab" will complete typing a file name or location). 
   

   cd Desktop/

   (hit Enter. This should take you to the location where you saved the file)
   

   chmod u+x UninstallScript.txt

   (hit Enter. This allows the script to become executable)
   
   
4. Finally, type this command to start the uninstallation process
   

   ./UninstallScript.txt

   (hit Enter - You will be asked to enter your computer password (not your Sophos password!), but for security reasons the Terminal will not show any characters as you type (not even stars), so it will look like you aren't typing) 
   
   Note: If you receive an error:  zsh: operation not permitted, then ensure "Terminal" has Full Disk Access under via System Preferences > Security & Privacy > Privacy > Full Disk Access. If the issue persists, try running the following command and repeat step 4 -
   

    xattr -d com.apple.quarantine ./UninstallScript.txt

5. Once the script has finished, reboot your computer and re-try installing Sophos Home after removing the device from your Sophos Home Dashboard 

Note:  If you know the exact location of the leftovers, or if you are having problems running the script, you may run each command separately inside a Terminal, one at a time, using an Administrator account.
(#!/bin/bash AND echo “Remove Sophos Home” are not necessary if running commands manually , instead of via script). It is very important to note that not copying the full line of a command may cause unwanted deletions to occur on your Mac. Please, be careful when copy-pasting each command.
