Re: Unusual message

Hi Pat,

Are you running High Sierra 10.13?
macOS High Sierra 10.13 introduces a new feature that requires user approval 
before loading newly-installed third-party kernel extensions (KEXTs). When a 
request is made to load a KEXT that the user has not yet approved, the load 
request is denied. Apps or installers that treat a KEXT load failure as a hard 
error will need to be changed to handle this new case.

Approval is automatically granted to third-party KEXTs that were already 
present when upgrading to macOS High Sierra.

This feature enforces that only kernel extensions approved by the user will be 
loaded on a system. When a request is made to load a KEXT that the user has not 
yet approved, the load request is denied and macOS presents the alert shown in 
Blocked kernel extension.

This prompts the user to approve the KEXT  You need to open System Preferences 
> Security & Privacy - General and click ‘Allow’ to approve the KEXT.

Cheers,

Ronni

Unusual message

[Pat]

I was just backing up my hard disc when a strange message popped up.
“System Extension Blocked

A program tried to load new system extension(s) signed by “Legacy Developer: 
Atto”.  If you want to enable these extensions, open Security & Privacy System 
Preferences.

Open Security Preferences  OK”

I searched on the internet for  “Legacy Developer: Atto” but the results still 
didn’t tell me what was happening. Should I open Security & Privacy System 
Preferences?

Cheers,

Pat
