Hi,Apparently some systems are stuck caching old catalogs which results in people thinking no new updates exist. You only have to reset the catalog to stock, run one "Checking for Updates" cycle, then switch back to Production or Seed.
First, huge thanks to dosdude1 and foxlet for the installer and catalog hacks. I'm happy to have my early 2008 MacBookPro4,1 (with newly replaced WiFi card!) running macOS Sierra.
I'll add a little note to foxlet's advice above, since I tried that when I had 10.12.1 and ended up unable to get App Store to show any OS updates available at all, even after resetting to stock, to Production or Seed. Further, at some point in my experimenting, App Store's behaviour changed:
- when I would click Updates it would quickly refresh the window but did not say "Checking for Updates" and spin the spinner for a minute as it used to
- when I would click the Store menu, I'd get Spinning Pinwheel (seems to never come back, requiring Force Quit)
Question: any opinions on whether App Store Preferences should have "Automatically check for updates" turned off? I did turn that off during my experimenting, and maybe that was part of the solution?
Many thanks again!
