Hi all
I tried to install the macOS Sierra Developer Preview.
Download worked fine, I start the wizard, enter my password and the remaining time counts down to almost 0, then I get the error below:
Error-Message (German) : Die Signaturprüfung des Installer-Payloads ist fehlgeschlagen.
Current OS: 10.11.5
I downloaded the file again, but still same issue. No idea how to debug/fix that...
Any ideas? Thanks
