Getting posix error -536870212 within appstores

jaimesharp,

Thanks for the update. I appreciate the work you have put in. As you can sign in to iCloud, you shouldn’t need to change your password as a troubleshooting step.

I would like to see if you can access the App Store on your Mac while it is booted into safe mode.

Use safe mode to isolate issues with your Mac

"Safe mode (sometimes called safe boot) is a way to start up your Mac so that it performs certain checks and prevents some software from automatically loading or opening. Starting your Mac in safe mode does the following:

• Verifies your startup disk and attempts to repair directory issues, if needed
• Loads only required kernel extensions
• Prevents startup items and login items from opening automatically
• Disables user-installed fonts 
• Deletes font caches, kernel cache, and other system cache files

If your Mac has an issue that goes away when you start up in safe mode, you might be able to isolate the cause."

I would also like to know if you can access the App Store while in a test user. "If an issue stops happening when you log out of your macOS user account and log in with another, the issue could be related to the files or settings in your user account."

How to test an issue in another user account on your Mac

Once it's determined if this is occurring in safe mode or while booted into a test user, there should be a path on how to resolve this!

Regards.

Hello, I understand that you are encountering an error when attempting to connect to the App Store. I’m glad to lend a hand.

I would start first with the Apple Support articles, If you can’t download or update apps on your iPhone or other Apple device and If you can't connect to the App Store, iTunes Store, or other Apple services.

A key call out from the second article is to "Update to the latest version of iOS or iPadOS, macOS, tvOS, watchOS." 

I would also suggest restarting your Mac in-between each step from the support articles. Log out, sleep, restart, or shut down your Mac

Best Regards.
