I messed around with my certificates in the keychain, because I have troubles with it in xCode. The problem is, I accidently deleted also certificates for the Mac App Store. Now every app from the Mac App Store says:


“[name]” is damaged and can’t be opened.

Delete “[name]” and download it again from the App Store.


OK, this hint doesn't help.


Which certificates, keys etc. do I need and where can I get it? (I have a second Mac activated for the Mac App Store but no backup for this Mac.)


Thank you!!
