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

Thanks for you comment on my related post. I have since elaborated on the issue after further testing today. My problem has only emerged in the past couple days after doing my High Sierra clean rebuild (a clean OS install was long overdue). When did your issue start?

Excellent news!

I don't exactly recall, but I do believe in each of my attempts...

...I created a new Mac OS Extended (Journaled) partition and then secure erased the entire drive (just to be sure :);

...I then did the reinstall of High Sierra, which now seems to convert the installation drive to APFS, which is not what I want but oh well Apple knows best. ;-P

...I'm pretty sure in one of my attempts I started with APFS formatted partition but I can't remember as I was starting to get frustrated.

I'm going to try it again as you have stated:

"...reformate... APFS instead of Mac OS Extended... clean install of High Sierra"

It will try to post later in the day if I am successful in this first step. If so I will also try to do a restore of my users and settings from a current Time Machine backup.

I’m so glad I found this, for a moment I thought I was the only one with this issue.

I am on a Mac Pro 5,1 and freshly installed High Sierra last Sunday.

Something I do always first when installing macOS ‘freshly’ is downloading AppStore applications I use on a regular basis. For me every single application I tried to download was not working (sometimes I couldn’t even download it). It would close immediately after opening it, and I’d get the same report:

Exception Type: EXC_CRASH (Code Signature Invalid)

Termination Reason: Namespace CODESIGNING, Code 0x1

Also, when I installed Pages, Numbers and Keynote each app appeared in the AppStore under “3 incompatible updates”.

I tried all kind of tricks people suggested, but so far nothing worked.

For now I installed OS X El Capitan on a second drive, there everything works fine. I hope this issue will be resolved soon.

I’m currently doing some additional testing to validate our situation.

I did a restore back to the original system that came with my iMac and I’m upgrading to each OS sequentiality and testing the App Store. I started with Lion LOL and not too much works unpatched. I expected this because it pretty old OS, but I needed to start at a factory condition. Anyway, so far I have completed Mountain Lion and Mavericks and the issue is not present. The App Store functions correctly, compatible apps download correctly, and best of all.... they start without error. It’s time consuming but I will continue to test all they way up to High Sierra and post my findings

I have the same problem. All apps I download from the App Store do not work. Downloading works. Do not open. Use High Sierra version 10.13.6

Newly uploaded on 11/17/2020

All tricks (reinstall, create new user, etc.) do not work.

The Affinity Photo App worked until the reinstallation of High Sierra.

Has Apple already announced something?

I have the same issue, whenever I open Pages, Numbers or Keynote, it shows the "Open File" Dialog for a few seconds and then they crash.

However, I have a different error report, I don't see the CODESIGNING anywhere:

It says

Termination Reason:    Namespace SIGNAL, Code 0x4

Any idea how I can fix this? I already tried reinstalling the from the App Store, but that didn't help.

Yep you would think so but in the end of the day apple doesn't care. Even if the entire OS X wasn't working they wouldn't do anything except tell us to update. I filed the report in hope that this company that we all love actually does something to help their customers.

Yesterday reinstalled High Sierra (10.13.6) on MacBook Pro 8.1 (MD313).

Faced with problems launching applications from the AppStore - Microsoft Remote Desktop and The Unarchiver

I hope that Apple will solve this problem.

I have the same problem. MacBook Pro 2011 with new installed OS ( High Sierra 10.13.6 with all available updates ) an EVERY App installed from App Store crashes at startup with Error Signature invalid. I reinstalled the OS 3-4 times over the internet recovery, but this error stay consistent. :(

For example MS Word from App Store...

Wow am I pleased its not just me.

tried the fix for an app Etrecheck and it worked but hasn't worked for pages. which is really annoying. I have purchased an old Mac for my daughters Christmas present and had to reinstall everything. Running High Siera but although can download the apps from the app store I need, Pages, Numbers, Keynote won't open, just crash with code, signature invalid error. come on apple help use out here...

Please... I'm from France and I didn't understand everything, I'm a bit lost between the different answers and threads... Could someone please recap exactly which is the procedure that works ? And explain it for example for Pages ?

Thaaaaank you so much !

👍
