AutoCad LT for Mac 2019.2 Update Combo package can't be opened because Apple cannot check it for malicious software

[mzarchs]

I've tried several days now to update my AutoCad LT for Mac 2019 but keeping receiving the message: "AutoCad LT for Mac 2019.2 Update Combo package can't be opened because Apple cannot check it for malicious software." from OS 10.15.7 Catalina.

Any assistance will be greatly appreciated.  Thanks.

Hi @mzarchs 

Please look at these articles on how to allow to open such applications:

and "How to open an app that hasn’t been notarized or is from an unidentified developer" section of this article:

Not really sure why this Update gives such notification, but if you downloaded it from here:

https://knowledge.autodesk.com/support/autocad-lt-for-mac/downloads/caas/downloads/content/autocad-l...

you can trust it.

Thanks.  2019.2 is up and running.  I should have thought of looking at the system preferences.
