Just upgraded to 'Low' Sierra (from El Cap) and am working my way through fixing annoying changes. One I can't figure how to fix is with Mail. I use the 'classic layout' with the Inbox sorted by date received (ascending so that the latest Mail is at the bottom). Prior to the upgrade, when I'd open Mail the Inbox view was such that it was positioned showing the bottom of the mail list so that new mail was showing. Now, the Inbox view is at the top of the mail list and I can't find a way to change this back to the way it was. I've gone through lots of reboots (for other things) and stop/start of Mail, no change. I suspect it's a tweak in a plist, but not sure what it would be. Any ideas?
