Mac intermittent shutdown

Hey all,


I am facing an intermittent shutdown issue after the fresh install of Catalina v 10.15.7. Please can you all help with how I can diagnose this.

After doing a little digging I was able to pull this from the Mac Analytics tab in the console. This was the same tab when the computer turned off.

Please let me know if you all need any more information

The immediate thing am seeing is " Signing” certificate is expired" . Is the media of Catalina an older on-hand copy that may be from from time ago?


Suggest  How to get old versions of macOS and verify what version this computer Qualifies to install. Make sure to use Only Safari to commence the download as Other may not work


Then Create a Bootable installer and try again
