Updates/Releases for Mac OS X

I finally got my hands on a nice pre-owned Apple Mac Mini at a reasonable price from that well-known online auction site 😉 so I’ve been able to update the Mac OS X version of the Blue Nebula Librarian app to the latest version (4.03) and the new MemBuilder app is now available for Mac OS X too.DSC06063 copy

My Mac Mini is running macOS Sierra 10.12.6 but these apps should work with any Mac OS X from 10.9 onwards.

Important: If you are new to these Blue Nebula apps and you haven’t already done so, you will need to install the Java Runtime Environment (JRE) from this page on the Oracle website (choose the .dmg Mac OS X file).

To allow the Librarian and the Blue Nebula to communicate with each other you will also need to install the driver for the CH340 USB-Serial chip in the Blue Nebula, if you haven’t already done so before. (This driver is not required for MemBuilder).

Since the last release of Librarian for Mac OS X I have found a ‘signed’ version of the driver which simplifies the installation. You can find the driver here and once it’s been downloaded to your Mac double click it to unzip it, then double-click CH34x_Install_V1.4.pkg and follow the instructions. Restart your computer after installing. When you connect the Blue Nebula to your Mac and run the Librarian, click the Serial Port drop down and you should see /dev/cu/wchusbserial440 in the list (the number may differ). This is your Blue Nebula’s serial port.

If you are a Mac OS X user please leave a comment below to let me know that you are using these apps.

    Thanks for this Travis. It was a broken link caused when Dropbox changed the way they handle permissions. I’ve fixed it now. 🙂

    A lttle help – please…
    I’ve done as recommended – but my Macbook crashes – when I connect the BN – and restarts, when I disconnect 😦 Any ideas – what happens?

      Hi Henning,

      Did you install the CH340 driver? – See the FAQ page for a link to where it can be found.

      Maybe try a different USB port or a different USB cable? It sounds like there could be a short circuit in the cable which is pulling the Mac’s 5V supply down and making it crash, so when you remove the cable the voltage is back to normal and so the Mac restarts.

      Can you try the cable with another device (not the BN) and see if it works? If it does you may have a faulty USB port in the BN.

      If you have a friend with a Windows PC maybe you could try your BN with the same cable on theirs? They don’t need the BN software installed, it’s just to check if the fault is in the cable, the BN or the USB port on your MacBook.
