Very Strange When I try to make any certificate by uploading csr file. It gives me error through the browser that invalid certificate. and I am not able to create certificate. but when I am doing the same thing with another machine its creating the certificate. I have gone through this answer
but I am not able to download the new CSR from apple . I think we can download new WWDR certificate.
If any one can help me in this I really fed up with this. Every time I have to use another Mac and then create new certificate from that mac and export it to p.12 file and then I can install in my Mac.
Thanks in advance.
UserName should not be empty when you try to create CSR Like this
