Have checked and pretty much same thing logged here (Bookmarks not shown in bookmarks bar after sync) but sadly that was given no response and closed after 60 days.
So I just reset my MacBook Pro to sync with my iMac and this appears to have worked but the bookmarks bar is now empty on the MacBook Pro.
Screen capture 1 shows empty bookmarks bar but full bookmarks toolbar (according to screen content).
Screen capture 2 shows that the sync seems to work but the sync does not know laptop name (this screen on laptop) so I am wondering if this may be part of the problem.
Version info on laptop (where problem is):
Any simple advice appreciated.
