Didn’t work for me and is driving me Nuts

I have the book on Kindle for Mac and also Iphone as well as the Kindle its self. Frustratingly, even with Sync turned off in in Amazon, the blasted things are still syncing to the last location on the Kindle for Mac (which was a mistake) and so a pain in the butt to keep the items in Sync. HELP!!! Making me sick now!
