System Preferences keeps telling me there are updates available but when I try to get them they time out and won't load. The last time this happened I got on to apple on line help - they upgraded me to the latest version of the os (a process that took about 8 hours!!!) and things have not been the same since - Safari has become very selective in what it will show and I've had tp migrate my bookmarks to Chrome which works well but I would prefer not to be using the 'evil' service.
