Improvements

Improved high CPU usage by requiring a short 5-minute delay prior to starting a new rescan after having already started the rescan baseline sequence

Improvements to Network Control, including inbound connections, are now being monitored. This can be changed in the products section
Improved and simplifies the uninstall process

The full path is now displayed in the Blocked Items Window
Improved caching for filesystem and application events for faster response and less CPU usage
Elevation Control – limited functionality (see notes below)
Elevated Policies – limited functionality (see notes below)
Added ability to turn modules on and off
TL Tray - View Button is hidden for Explicit Deny Policies

New Features

Added Learning Mode (Hash Only) to the MAC
Added three hard-coded process exclusions to the MAC agent to reduce unneeded Unified Audit Logs. BackupD, MDSync, and Bird will continue to run in the background but not be monitored by ThreatLocker
Added the Install action for MACs
Added the ability for the MAC computer groups to turn products on and off
Added the ability to detect installing pkg files from the command line
Added ability to Elevate additional system settings for MacOS 13.0-13.4, including:

Network Settings
Login Items
Sharing Settings
Time Machine Settings
Privacy & Security Settings

The Elevation improvements that were added for MacOS 13.3 are coming soon to MacOS 13.1 and MacOS 12
Elevation Control may not support all elevation request types. If you find that elevation shows a password prompt without the ability to request elevation, please document and report to a Cyber Hero
Silent elevation is not currently supported
