App Store apps do not install properly on a fresh install of High Sierra on internal SSD or HDD

Hey. Mojave still supports 32bit apps. However you will get the annoying warning that says it isn’t optimized for your Mac or it need to be updated soon. You can find some terminal commands online to suppress that warning.

My copy of macOS High Sierra 10.13.6 was download directly from Apple https://support.apple.com/en-us/HT211683 the macOS High Sierra link provided in this page will redirect you to download High Sierra from the AppStore. Once you download it from the AppStore you can make a bootable USB drive.

Just to make sure I understand correctly. The App Store apps worked when you did a clean install but didn't sign in with your Apple ID on the setup screen and didn't install the security updates? To download the apps you have to sign in with your Apple ID to be able to download your purchased apps. And what happens after installing the updates? Do the already downloaded apps stop working?

Sorry for all the questions.

After issuing the code sign command for Numbers. The app now launches, but then crashes when trying to open new and existing spreadsheets. The error report says "Termination Reason: Namespace SIGNAL, Code 0x4"

I will try whit the terminal command once the security update finishes installing. After that i will try whit testing the apps and post my results. So far, the most stable way is in the procedure i posted earlyer. If afrer the terminal command, the apps become unstable, i will reinstall the os but take pictures so i can post the installation process.

Just came across another app that simply won't run AND leaves no crash report whatsoever (the weatherbug app). Same thing, came from app store, did a reinstall and open try that does nothing at all.

This is really outrageous... their aim obviously is to funnel everything through their store, so you'd think issues like this would get their attention and solution pronto.

I think it's called "crickets."

I kinda appreciate so many being seriously in the weeds here, but the issue remains, I can NOT d/l ANYTHING from the app store in addition to 2 apps I've already used before (I even went back to a version of one app that worked BEFORE I did the HS update, it fails on launch just like the version I tried to get from the app store). Has Cupertino had ANY response?

well, the workaround above worked before I applied the 005-006 security patches. One thing I noticed it at the first time I checked Signing Info, it gave me "Microsoft Remote Desktop signed, but certificate has been revoked!", then on the second try it gave

Microsoft Remote Desktop is validly signed & notarized

(Signer: Apple Dev-ID)

This whole issue has seemingly taken over my life now! I think we are of like mind... they made new, far more restrictive rules for developers and arbitrarily applied them all across the board. The 3 highlighted apps in my experience all very much point to it. Fortunately, so far I have not found any other existing apps I have suffering... and the three are not indispensable for me. Even so, my expectation is that the App Store is now shut down for me... I have zero confidence anything I bother downloading will ever work. Good thing for me is my beloved cMP makes for a pretty good winblozen machine... guess I should start getting a lot of more familiar with it. I'll post back here if I ever do get escalated to Tier 3 support.

I can sign into this forum in Safari. The link gives me a "Page Not Found" error. Even after I remove the comma at the end.

EDIT.

I can get to the idmsa.apple.com address if I use this
