updated my 2012 mac 8GB now it is beachballing constantly

Hi johnnyd27,

I believe we need to proceed with an EtreCheck report. EtreCheck is a useful app to diagnose issues, both hardware and software. It is trusted by many users. Please follow the steps outlined below:

1. Go to the Mac App Store and search for "EtreCheck."
2. Download it. It is a free and trusted app; as it is on the Mac App Store, and only trusted apps can be submitted.
3. Run the report, and put it in a post, as seen here - https://discussions.apple.com/docs/DOC-250000211 We will then examine the report for issues in your Mac.
4. If it asks for Full Disk Access, follow the prompts to enable it.

I think that you should also run Apple Diagnostics -  Use Apple Diagnostics to test your Mac - Apple Support Please post the Reference code when done.

Please post results of both!

Cheers,

Jack

What software did you update? What apps are giving your the beach balling? Have you installed or run any "cleaning", "optimizing", "speed-up" or anti-virus apps on your Mac?
