1) Any solutions to the failure to synch the Profiles?

iMac to MacBook Pro Syncs: After a synch, target (MacBook Pro) launched in Default (instead of my selected theme) and settings could not be accessed by clicking on any of them). Also, no images would appear in any website. (FF Default all-grey browser is not usable for me because of poor eyesight and the need for more color and contrast in the mix). Consultant troubleshot all my Extensions on both devices (tossing many extensions and most themes) then synced again. Still no images and prefs still unavailable by clicking on them. I kept one seemingly safe theme and was able to have both devices stabilize their respective themes and regained access to settings. We tried to sync once with an added test bookmark. He got the theme to launch and the images to appear and then we synced . Boom! Back to square one. Finally he got both devices to work independently so we banned any syncing. Fine, except that I REQUIRE syncs. 1) Any solutions to the failure to synch the Profiles? 2) Any easy syncing strategies other than don't involve digging into the Library files and manually swapping folders around. It works but too much room for tired eyes at night. Any decent after-market apps that will do just the Profile synch, both ways? Many thanks.
