OK, i installed El Cap last night, and so far it's all good. Before i went to El Cap, i switched back from Google Chrome to Safari. Haven't been with Safari for about two years, and i have to say that it's changed for the better. Anyway, i figured that it would go smoother if i had Safari on Yosemite when i upgraded. For whatever reason, it went smooth as butter, or Nutella, if you prefer. No problems on the Mac side of my MacBook Pro, but on the Windows 10 side, i can't get Safari, so i'll have to continue with Chrome. Just figured that i'd let anybody know who had their MacBook partitioned as i did.
