Question

Can I use someone else’s Apple’s Developer Certificate and Provisioning Profile to build and run my application on the iPad ? Are the certificates and profiles Machine Specific ?

Actually I am trying to install my friend’s dev certificate and it is getting installed but when I am installing the provisioning profile its showing me an yellow warning “

The main question is that The Developer’ Certificate and Provisioning profile can be used on different machines or not ?

Answer 1

“Error: “A valid signing identity
matching this profile could not be
found in your keychain”

Solution: Most likely that you have
not downloaded the necessary WWDR
certificate from the Apple developer
site. There is a link to download this
certificate in the ‘Certificates’
section of the developer portal. If
you do have the certificate in your
keychain, make sure that it has not
expired (unlikely, as mine is valid
until 2016). Also make sure that your
developer certificate has not expired
(these seem to be valid for only 12
months at a time).”
