Nuno on a Mac 2

Now there is a new way to use Nuno on a Mac. A single download that contains Nuno, UK charts and the ability to run the software on Mac OSX without requiring you to buy a Windows licence and do any other setting up.

It works by using a software project called "Wine" that allows Windows application to run on Unix type OSs like Linux and Mac OSX. You don't need to know about Wine but here's the wikipedia entry.

Alternative (Running real Windows)

This isn't what this post is about, but:

The other way to run Nuno (and Windows software in general) on your Mac is to install Windows. To help there are a variety of tools, for a start there is Bootcamp which is supplied by Apple and ready to go on all new Macs. Bootcamp allows you to "dual boot" - so you can choose Windows or OSX but you have to reboot to switch.

Other tools like Fusion and Parallels allow you to run Windows Applications in a window inside OSX. Some of these tools are free and some paid for but they all need you to buy or have access to a Windows licence (about £80). If you want or need to use several Windows programs running real Windows is the way to go. 

Overall, there are tradeoffs around cost and performance. Bootcamp is my personal favourite, you get the full benefit of a retina display and Windows runs brilliant on the nice Mac hardware and I don't find the swapping back and forth too upsetting. 

If you have Windows installed just install Nuno from the usual Nuno download page

Beta Release

This is a beta release! So please download it and give it a try. There's a bunch of ways to give us feedback including the feedback button on the download page.

There's more about what a beta release means in my previous blog post. 


Be warned that the download is fairly large (1.6 GB) and I recommend you start with at least 10 GB spare on your disk because it is a compressed disk image that expands out and then needs some elbow room in which to work.

(Really you should have way more than 10GB free if you want your Mac, or Windows PC, to run nicely.)

If that's ok click the link: Download Nuno_3_2_71.dmg

Depending on your connection that download might take some time - when it's done and you double click it it will whirr a bit whilst it uncompresses and then present you with the familiar "drag into Applications" install.

Click the Nuno icon and drag it into Applications.

When it's done you can run Nuno_3_2_71 from the Launchpad or from Finder like any other app. First time around Wine will do some setup - it only needs to do that the first time you run it.

Now you should see Nuno ready to activate. If you have made a Nuno account on the website or by using Nuno on a PC you already have an account or you can create on from here. After you have activated Nuno it will unlock the charts for UK waters. You can now browse the charts, create routes and so on. 

Connecting a GPS

Connecting a GPS is less automatic that it is when using Windows and worse still it (currently at least) involves typing commands into a terminal (there's some 1970s mainframe software lurking under all that the lovely usability.)

We're sorry that this bit gets a little technical and we might do something to smooth it over. Let us know how you get on.

This stuff applies to AIS as well - it's really just about connecting a device that can produce the NMEA text.

First step is to connect the device to you Mac. This will either just work or you can follow the manufacturers instructions. I connected a Blue Next bluetooth GPS by going to Preferences > Bluetooth and then turning bluetooth on a pairing with the device. Then I went to the Terminal (Launchpad > Terminal) and typed:

ls /dev/tty.*

That lists out all the serial ports available and in there was /dev/tty.BT-GPS-COM7 - you can do it before and after you connect your device and spot the new one. 

What we need to do now is create a link from the GPS, in this example called /dev/tty.BT-GPS-COM7 to Windows style serial port name "COM1" in the correct place on the disk.

All the settings for the Wine Nuno are held at ~/Library/Application\ Support/com.chersoft.nuno_142963160111409/dosdevices/ on the mac. So you need a terminal pointing at that folder. So,

cd ~/Library/Application\ Support/com.chersoft.nuno_142963160111409/dosdevices/

(Copy and paste that in ;-)

Now that you are in the right place there's one more magic command to create the link

ln -s /dev/tty.BT-GPS-COM7 com1

Now when you use the "ls" command or Finder to view the contents of that folder you will see com1 in there.

Next you need to know the details about how fast the GPS/AIS transmits NMEA. Mostly this will be 4800 8-N-1 or 9600 8-N-1, that is for example 4800 bits per second 8 bits per character, no parity and one stop bit. You don't need to understand what that means just match the config to the GPS or AIS. It might be written on that actual device or in the manual. Get in touch if you need help with this.

The download is ready for 9600 baud devices 8 bits per character no parity and one stop bit.

If you need to change this there is a file to edit called SYSTEM.REG at ~/Library/Application\ Support/com.chersoft.nuno_142963160111409/ - you can carefully edit it with TextEdit. About half a screenful down there is a setting like this:

"White list"="2,COM1,9600,8,0"

Carefully edit that taking care not to replace the quotes with fancy opening and closing quotes.

For example iff you want to change the speed to 4800 that replaces the 9600. If you need to fit in with more unusual settings please get in touch.

So there it is...

Ok, that's probably enough detail for now. Plenty of people have asked for this. Sorry it took longer than we hoped (it was harder!). Hope it comes in handy.
