Cortex error message

[leonabarratt]

I keep getting a popup message from Cortex saying "Cortex needs to access your entire harddrive."
Why is this message coming up and how do I get rid of it?
I've tried reinstalling Cortex, updating the Mac OS, restarting my computer, and yet it keeps coming up on both of my Macs.

Thanks for any help!

Hi @leonabarratt-

I pulled this from the admin guide - hope it helps.

Due to changes in the security settings of macOS 10.15, you must allow Cortex XDR full disk access on your endpoint to enable full protection. If you do not authorize Cortex XDR full disk access on your endpoint, the agent provides only partial protection of files in the 

/Applications directory. The first time the Cortex XDR agent detects an attempt to run an executable file located in another protected location on the endpoint as part of the anti-malware flow, macOS will deny the agent access and prompts the user to grant full disk access.
