USB to ethernet (Apple) apparently this seems to be a 100Mb/s ethernet so don’t expect fantastic speeds from this. USB-c to ethernet gigabit - good speeds giving me about 60-70 MB/s read/writes With my Mac purchases, I also purchased a few different attachments Incremental backups may be ok, but don’t backup a 128GB of data on wifi only it can be done but it would be exasperating. I’ve tested this over and over and over again and have been caught running at wifi speeds while doing mass copies and it isn’t until a half hour later, doing other stuff, when I notice that my copying is still copying.Īlthough Wifi is just great for most usage, like surfing the net, copying one or two files and even a folder of photos which usually take a few minutes, don’t depend on Wifi to do your full backup. UPDATE WARNING! Even though you think you have properly set up your service orders and your ethernet Gigabit shows active on top, you may still be running under WiFi speeds. So I’ve been playing with my new Macbook 12' Retina and my Macbook Pro 13' and have been making observations I’ll be keeping only one of the two, although it would be nice to keep both.

Mac ethernet and wifi same time
