As it may have gotten lost in this long thread, be advised that if you are using XCode 8, code signing is not exactly the same as in XCode7, see: Migrating Code Signing Configurations to Xcode 8
Please let me know if this link does not address and resolve the code signing issue you are currently experiencing. If it does not, please start a new post as this one is becoming long and hard to follow (Be sure to restate the issue, provide repro steps and associated logs.)
I verified that the patch from issue 38006 is in 4.14.0-release, but it didn’t fix the issue! It works if you cherry-pick that patch into 4.13.2, but not in 4.14.0 itself.
I have done everything possible and cant get my Provisions into UE 4.17 on MacOS 10 High . I went into my Xcode 9.2 and all my certificates and provisions are working and syncing with the Developer online account bundle ID. When I go into project settings of Unreal Engine it shows my Developer and Distribution Certificates, but my Provisions are not showing up and I don’t get any green colors on either.
When I try to manually import the adhoc provision for example, the output log says “IPP ERROR: Failed to find plist in .mobileprovisions file” what is this referring too when all certificates and provisions are located in the Project/Build/IOS directory.
I have also scoured the internet and this site and still can’t figure it out. I am still learning and must be missing something in UE 4.17 for this error to occur.
