Apps from Mac App Store crash when started (CODESIGNING error)

Thanks! :) 👍

Worked for MacTracker and TextWrangler. Guess I will try numbers and pages.

Thanks.

Thanks. Might require a Reinstall now.

I have the same issue and it is good to know I'm not the only one. With the experiences I've had with apple, I'm afraid they won't fix it. They don't like to spend time on previous OSXs...

Many thanks for the tip

I have just sent this problem to that address

When I try the terminal command for pages, I get this: "The specified item could not be found in the keychain."

You left out the part where you need to install the utility "What's Your Sign" which adds the signer info line to the contextual menu.

worked for me, thank you so much man!

It works

Thank you!

Good

Has this been sorted by Apple yet?

It has reportedly been fixed.

Thank you. Has anyone tried upgrading to HS successfully etc?

Sorry, I upgraded but have no Apps from the App Store.

I have to agree with you on the summation that it is an Apple problem, which is probably caused by changes related to their recent announcements (new OS, Macs, etc.). My issue surfaced only Wednesday (Mountain Standard Time). On Tuesday I backed up data and prepared the computer for a complete erase and install of High Sierra.

I have just completed another test on a pristine install of High Sierra but this time I had someone else created the default account (admin) and associate their Apple ID so that it would be the account used when downloading from the App Store. They are getting the same issues.

This needs to be fixed! With this pandemic and current politically unstable climate, my financial resources are reserved for important needs; I can NOT afford to be spending money on a new Mac just to keep pace with Apple's changes. If that were the case I would buy a Windows PC for a fraction of the cost and throw it out every couple of years and buy a new one. I would prefer to buy a Mac and have it last.
