Some Mac App Store Apps 'Damaged' Due to Expired Security Certificate

A reboot did indeed fix it for me. It asked me to sign back in to the app store, said it was verifying the app, and then updated the certificate chain:

$ openssl pkcs7 -inform der -in /Applications/1Password.app/Contents/_MASReceipt/receipt -print_certs -text
Certificate:
Data:
Version: 3 (0x2)
Serial Number:
52:a4:b9:c5:e1:b1:18:81
Signature Algorithm: sha256WithRSAEncryption
Issuer: C=US, O=Apple Inc., OU=Apple Worldwide Developer Relations, CN=Apple Worldwide Developer Relations Certification Authority
Validity
Not Before: Sep 24 19:09:31 2015 GMT
Not After : Oct 23 19:09:31 2017 GMT
Subject: CN=Mac App Store and iTunes Store Receipt Signing, OU=Apple Worldwide Developer Relations, O=Apple Inc., C=US

 

The good news for me is it only keeps me from using Apple apps as they are the only mac app store apps I have.

 

It is a big deal when some apps won't even launch. It's a bigger deal when uninstalling and reinstalling those apps, signing out and signing back in, booting in safe mode, and rebooting over and over again doesn't make them work again.

 

It just **works**!

Really though --
Where's the quality that goes with the premium price we paid? Oh yeah, we got that super-slimmed down <insert device name here>.

Apple's brand image is in the toilet as far as I'm concerned.

This is major issue #5 for El Cap that I'm experiencing. Seriously considering rolling back to Yosemite.

 

I was getting this with VLC when I tried to run it, but then it just stopped after I told it to accept all apps. I know where I get all my apps from.

 

Sorry, couldn’t find that bit. Is it the “ha..ha..ha....” in line 3?

 

Zero issues here with El Cap, and on four machines.

 

I had the same problem with 1Password and Screenium. With 1Password it was easily solved by entering my Apple ID password. However, with Screenium nothing worked. I tried everything including a completely fresh install of El Capitan!

I wrote to the developers of Screenium who offered me to download a non-AppStore version that works fine. Very good service considering that this is clearly Apple's fault.

 

Similar experience today with the Battery Health app on my MacBook Air/El Capitan.

 

No doubt this will be corrected shortly .

 

For anyone getting the sign-in prompts saying your purchase was made with another computer - you can solve this by opening the Mac App Store app, clicking on your name and signing in. This worked for me on 2 machines. Once doing that, all the apps opened fine.

Who cares. AAPL is still going up, right?

 

I honestly thought this was just me with this issue. I ran XSlimmer last night when I left the office and woke up and couldn't open MarsEdit or Reeder for Mac.

I restarted, issue persisted.

uninstalled all Mac App Store apps from the last 3 years, reinstalled all of the ones I still use (thanks Apple for the force housecleaning)

Everything is working fine now.

 

I probably have the same issue with DropZone because I was prompted to type the password. So I just ignored I'm too lazy because I don't remember my password and have to open my 1Password. Besides I hardly use the app so that's one of the reason why I just ignored it too.

 

Apple is doomed.

Can't even get El Capitan to work. I guess if you did a restore from Internet, it also gets this problem from MAS.

Windows 10 is looking great.

 

Happened to me. Reboot fixed it. Pretty annoying. Wish I could still buy software on CD.

 

Had this issue with DaisyDisk on El Capitan yesterday, too. The Mac App Store is really beginning to feel like a house of cards now.

 

Adobe Photoshop Elements 10 has been affected ever since this morning on all of my machines. I don't use this app very often but luck would have it that I am building a site this week and just cannot live without it. I have got it up and running on an old macbook, before I booted it up I switch off the wifi connection. It kicked and screamed at me but I was able to ignore error messages and get on.

Fix please Apple

 

Add SimCity 4 to your list.....

 

I don't deny the fact that someone here would hate this comment. But denying that you don't hate is ignorant. You're just like people who ignite and then deny it that you're not involved. Besides we're talking about OS X here so it's not relevant. Most likely people are mad at you, because how stupid you are talking different from the topic.

 

I had this problem with BBEdit. I found that deleting the app from my computer and redownloading from the App Store fixed the problem. It did not loose state and reopened with the same files I had opened before the problem.

 

A question, if I may: Is it a requirement that MAS apps contact Apple before opening?

 

Billings 3 is still not working on 10.10.5, even after a sign out, delete, reboot and re-install. Frustrating!

 

This is why as great as an appstore is to consolidate all your downloading/updated of software, I still prefer to be able to buy direct so that I'm not reliant on Apple's cloud services/etc to run them. Oh I still buy from the app store. But I do prefer to buy direct.

 

Have the same problem with Tweetbot (doesnt even open). I guess time to move away from the apple store.
