I’ve read lots of posts about this and may have missed a crucial detail but haven’t seen this exact situation.
I’m trying to connect my Macbook Air to my My Book Live to do a fast backup. I’m using a USB Gigabit Ethernet Adaptor into a standard Ethernet cable connected to my My Book. In network I see “USB Gigabit Ethernet Adaptor” and it obtains an IP via DHCP. I’ve also set the IP manually and in both cases can now see MyBook Live and My Book Live-backup in Finder under Shared. When I click on either they try to connect for some time before disappearing. I can’t acces via the URL either. Feels like there is just one way communication or an access issue.
All help greatly appreciated, I have to turn my Air back in as the trackpad has broken and need to backup desperately!!
