Working into an issue that claims “Installer data on the restoration server is broken” when making an attempt to re-install MacOS (Sierra) on Macbook Air 2017. Most tutorials/”fixes” on Youtube/the web inform me to vary my system’s date to love 2018, which does not repair something..
The precise error within the set up log tells me the next:
Didn't open OSInstaller as a result of the installer isn't trusted: Error Area=PKProductErrorDomain Code=0 "(null)" UserInfo={PKTrustlLevel=3, NSUnderlyingError=0x7f9d65522950 {Error Area=NSOSStatusErrorDomain Code=-2147409654 "CSSMERR_TP_CERT_EXPIRED" UserInfo={SecTrustResult=5, PKTrustLevel=PKTrustLevelExpiredCertificate, NSLocalizedFailureReason=CSSMERR_TP_CERT_EXPIRED}}}
If anybody has expertise with this or an thought find out how to repair this, please let me know.
