Since I deleted
Deleted the Library/MobileDevice/Provisioning Profiles and let Xcode reinstall
All the old greyed to certificates have disappeared from Xcode, the once that keychain didn’t have which is a good sign but now the Apple Development Certificate for my computer is greyed out and says not in keychain so I have stuffed up something else.
When I look in the keychain it actually show the certificate is in the keychain
I’m trying to be mindful and not wreck the Mac App certificates I had in place for the last project… or doesn’t it matter and I can delete everything and start again??
