I had to upgrade to Macbook 2016 running Sierra 10.12.2 recently as old MacBook Pro died.
I have been running Drobo Gen2 4-Bay (currently with 3 disks with 11% to go all green lights with one yellow). The Dashboard can find the Drobo and running latest firmware and dashboard.
Drobo doesn’t seem to show up in finder and not mounting. Any advice appreciated - is it time to upgrade to Drobo 5C? Is it easy to migrate from Drobo Gen2 to Drobo 5c?
