I have had Sierra beta in my purchased list since early in betas. A second item added when the GM for Sierra was released. That item for Sierra GM changed in Purchased to just macOS Sierra. So, today, at release time, I saw that the "Featured" tab in App Store now showed Sierra, replacing El Capitan. When I looked in "Purchases" the Sierra item had disappeared. The Sierra beta was still there. I can download from the Download link in the Featured tab. No problem - until the download slowed down incredibly (estimate 42 hours), then eventually failed with a "problem" popup. All quite expected, except the problem popup says "download again from the Purchases tab", and the macos Sierra is still missing from that tab. I booted to an El Capitan partition, and the App Store in my El Capitan system shows the Sierra as a purchased item. I though - OK, probably just a high traffic day, being the first day of full release and all. Download from the El Cap partition went without a hitch. (Found out I wasted my time, as it was identical to my last download of the GM ) So, App Store in El Cap shows my Sierra in the Purchased items. Booted back to Sierra, and still missing from App Store/Purchased list. I tried resetting some caches/plist files in the system to get App Store to reload purchases, but still no Sierra. Nothing else is affected. So, TL; DR... my question is: Anyone see something similar in App Store, and how can I reset the Purchased list so it reloads completely? I think I am not too sure where to go - caches, somewhere in /var/folders ? That area is sometimes very hit and miss for me.
