Provisioning certificate working on one computer doesn't work on the other one

Guys I do hope you can help me.

Back in February I went through all the hassle of creating a certificate as Apple Developer and asking my tutor to create me a provisioning file and add my devices (Apple Developer University Program).
It all worked on my MacBookPro and I was happy. Unreal would highlight in green my provisioning file and my Certificate as iPhone developer.

Fast forward a month and I’m doing an Internship 8hours across the globe.
First thing I do is having my new tutor assign me an iMac, I install Xcode, Unreal, set up my account on Xcode, create a certificate for the iMac, download the provisioning file and double click it (shouldn’t be needed anyways).
Test Deploying an app on my iPhone and done, it works.

Switch over to Unreal, let’s test this new AR template, open project settings and…the provisioning file is RED, saying “No Valid Certificate Found”, with my certificate as iPhone Developer RIGHT UNDER THERE.

If I import manually the provisioning file it is the same “No Valid Certificate found” problem
If I try building and deploying anyways I get this error:

LogPlayLevel: Code Signing Error: Provisioning profile “bartolomei-provisioning” doesn’t include signing certificate “iPhone Developer: Massimo Bortolamei (2HEP25L8WM)”.

LogPlayLevel: Code Signing Error: Code signing is required for product type ‘Application’ in SDK ‘iOS 11.2’

and it doesn’t make any sense since on the very next MacBook Pro on this same desk everything works fine!

What I tried:

  • playing around with timezones and shifting to GMT 0
  • checking that my Apple Worldwide Developer Relations Certification Authority is up to date.
  • looking at many many posts on Answerhub
  • close and reopen everything multiple times
  • redoing everything from scratch
  • deleting all the provision files in the folder Library/MobileDevice/ProvisioningProfiles and importing only the one downloaded from Dev Center manually.
  • you name it

What am I missing? I have other things on which to be stuck on, this can’t be one!
Thanks for help

Ok so, I was able to find what I think is a solution.

I have very basic understanding about code signing but it seems that the same keys and certificates I was using on my MacBookPro were linked somehow to the provisioning file I was using. Moving the provisioning file on the iMac would work fine for Xcode because it would manage things automatically, unfortunately Unreal doesn’t do so and it would complain about missing signing keys. I then approached the problem from another side (since I don’t have full permissions in the Dev Center because it is a university program) and looked into how to export the keys from one computer to another.

this addressed the issue perfectly The issues of exporting/importing certificate , private key under keychain access for Iphone

for the lazy: on the working pc go to Xcode>Preferences>Accounts>small gear icon next to + and - > export remember to put a password because it is very important stuff.

transfer the file to the other computer, double click, enter password and everything will be automatically imported!

close and reopen Xcode preferences and log into the account.

In unreal everything should be automagically imported.

Just remember to start from a clean situation (I had to import the file a couple of times actually) by manually deleting all keys and certificates from Keychain. This time unreal would show “Valid” next to the provisioning file, and while deploying it would ask for the keychain password.

And Done!
