I tried to validate my xcode project but it cause error that ‘the private key for “my name” is not installed on this mac”
Because this project was created by another Mac Computer.And that has broken. So , I can’t export this private key to it which I am using .
Do you have any idea?
Thanks in advance
You should revoke your distribution certificate in your account. So that it ask the

.cerkeyfile in your account again. You can create.cerfile in your keychain go toRequest a Certificate from a Certificate Authorityand give your details that your mail id etc. so that it will create.cerfile and indeveloper.apple.comyou can upload thecerfile once you revoke your distribution certificate so that it will generate the certificate which can be installed in your system.
