I'm sure I can't be the only one who has this setup. We have a "main" Mac, and both my wife and I have iPhones. The Mac and my phone are on my iCloud account, and my wife's phone is on her iCloud account. We keep all our pictures centrally on the Mac, and use Picasa to view them. The problem is that we can't easily download all the pictures from both iClouds onto the computer. I don't really want to use the Photos app (and even if we did, that would only get my photos), so the only kind-of solution I've come across is to use the iCloud website and try and download pictures individually or as a set. Really though, I want to download them all (several thousand in each account). Any solutions to this?
