Got a new Raspberry Pi 3 and I'm trying to use it with my Mac. I formatted the SD card and downloaded NOOBS. The green light comes on sometimes but when I add this to terminal:
ssh pi@raspberrypi.local
I get this error message:
ssh: Could not resolve hostname raspberrypi.local: nodename nor servname provided, or not known
Please advise.
A couple of things...
With NOOBS the initial setup has to be done with a directly connected keyboard and display, ssh isn't an option. So you'll either need to set that up or pick an OS for your initial install. I've been having good luck with Raspbian Stretch which you can download here.
Then, in the root of the SD card, you'll need to put a file named ssh – it can be empty. Just mount the card on your Mac, the SD card will show up in Devices in Finder and will probably be called boot – then it Terminal do:
touch /Volumes/boot/ssh
If the SD card isn't called boot substitute the name you see in Finder.
Then eject the card and put it back in the Pi and reboot the Pi.
Next you need to figure out what IP address the Pi has been assigned. I'm assuming that it is "headless" so you can't just watch the console. That would be too easy... So, take a look at this question: Find Raspberry PI address on local network, my favorite method is to ping the broadcast address on the network (X.Y.Z.255) then use arp -a | grep B8.
Once you connect to the Pi run the raspi-config command and permanently enable ssh it is under Option 5, Interfacing Options. As I understand it, the trick in step 1 is a one-time thing.
