I was hoping to use iCloud for this, but my MacBook is rather old and can’t run any version of OSX newer than MacOSX 10.6.8 “Snow Leopard” which doesn’t have iCloud installed, just it’s predecessor MobileMe… I just got a new iPhone 7, and now I want to transfer my photos from my previous iPhone 6 onto my MacBook. Hopefully there isn't some obscure issue with the update.UPDATE : the procedure outlined in this post still works for new iPhones with iOS11 and iOS12 (like the iPhone 7, 8, X, XS and XR) even though it was originally written for new iPhones running iOS10 (like the iPhone 6 and 6s) Most existing machines are still at 10.6.6.

After that everything is all packages and OS updates which get applied at or after imaging. I end up with a non-booted dmg that I run through Casper NetInstall Creator 3.2. I have been creating the caper dmg from the latest thunderbolt Macbook media and applying the 10.6.8 Combo uptate to that (offline) volume. I went in via dscl and Deleted the user from /Local/Default/Users, which resolved the issue and I didn't pursue it further. One similar login issue I did see with 10.6.8 was a user was *not* visible in System Prefs even though they had logged in many times. I always see every user who logs in under the accounts prefs. On my setup, all accounts are mobile accounts (Create mobile account at login in the AD plugin). It's interesting that you mention that the local user account showing in the prefs pane. I've been watching this thread with interest as I am currently updating the core OS of our images to 10.6.8.
