After installing NTFS or extFS for Mac, you receive this message after turning on your Mac:
‘com.paragon-software.installer’ is an app downloaded from the internet. Are you sure you want to open it?
Since recent Catalina updates (presumably 10.15.4), macOS adds suspicious files to quarantine. While it’s a good countermeasure against malware, some drivers and utilities such as our file system driver are also affected.
Please launch Terminal utility and execute this command:
sudo xattr -d com.apple.quarantine /Library/PrivilegedHelperTools/com.paragon-software.installer
This command will remove the attribute from the component that causes macOS to warn the user.
