Mac OS X
Q: Can't upgrade to "Sierra"
I am trying to download Mac OS X "Sierra" from the App Store, but I get an Error. Here is an excerpt from the log:
26.09.16 19:22:55,284 storedownloadd[477]: *** Assertion failure in -[CheckPreflightOperation verifyDistributionAtURL:allowsDevSign:allowsUnsigned:osVersionToBeInstalled:error:distributionController:], /SourceCache/Commerce/Commerce-376.29/CommerceKit/CheckPreflightOperation.m:290
I already deleted the App Store cache. I also tried to download it in safe mode. But no chance.
My current OS X version is 10.10.5 (Yosemite) on a MacBook Pro.
Any ideas?
MacBook Pro with Retina display, OS X Yosemite (10.10.5)
