I opened my Mac App Store and notice that it had signed me out. Then I tried to download something and it asked for my password, I entered it and it came up with a box saying:
An error occurred during purchase.
The operation couldn’t be completed.
com.apple.commerce.client error 500.
I tried the .plist file reboot thing, and it didn't do anything.
Can someone please help me.

Try setting up another admin user account to see if the same problem continues. Please post back on whether or not this worked. Also try the Safe Mode. Please post back on whether or not this worked.
Isolating an issue by using another user account
If it works in the Safe Mode, try running this program when booted normally and then copy and paste the output in a reply. The program was created by Etresoft, a frequent contributor.

contact iTunes Support. Either use the form or scroll to the bottom of the page in the 2nd link. Follow through the screens to get a chat or telephone option.
Contacted Apple support and they walked me through starting up in safe mode and trying the download. That worked, and it fixed the issue when I rebooted normally. The thing is I thought I had already tried it before calling support, but maybe I wasn't really in safe mode that time - there's no obvious indicator.
The solution on this thread worked for me. In essence I wasn't logged into iCloud. Logging into iCloud got things working.
I tried by creating a new admin user and it worked.
What happened when you tried while booted into the Safe Mode?
I had the same issue, but a combination of the update to the latest 10.14.3 and a system reboot fixed this.
I have the same issue and it still remains after setting up another account, safe mode and even reinstalling the system...
the operation could not be completed (com.apple.commerce.client error 500.)
why I can not use my App Store download anything now
Contact iTunes Support using the links posted above.
Turns out I spoke too soon. The behavior is different, but App Store still won't install any apps or restore my purchases. I just get a whirling circle for hours on end.
I am having the exact same issue. Could you let me know if you have fixed it? Thx
The problem dissapeared when I entered the details of my credit card, before I just skipped this step. No joke.
Mac App Store isn't letting me download Anything
