Update for UnitiQute with Mac....arghhh

Are you running El Capitan? If so I had same problem, fortunately I had another mac still running Yoesemite and that fixed the not communicating error.

Sadly the update then fell over at 99% repeatably while trying to update the ARM firmware so it's off to dealer Saturday to see if they can bring it back to life 

Till then the future is Vinyl and CD... really can't be bothered with all the messing about with networks, ripping etc. was just using the Uniti for FM and iRadio source.

Never mind this new muso thing Naim how about a nice new FM / DAB(+) / iRadio tuner

Ah yes I am indeed. My girlfriends old Mac might do the trick then. I'll give that a try and report back

No joy, still can't seem to connect!!  This is a joke.  Makes the Linn a piece of cake

There are new signed (authenticated) drivers for the RS233-USB converter that work in El Capitane, issued a month ago I guess. I updated my Mac driver and had no trouble last time I did the UnitiQute update so you might want to give that a go. Security settings on Mac were changed to deny access over the port (for sure with El Capitane, possibly also with a patch to Yosemite but I am not sure about that).

That's interesting thanks Alan. I actually used the driver on the website for the cable which appears to be the latest. It does have the recommended chip

Having had read this thread I have become ever more doubtful to upgrade UQ2 from 4.1 to 4.4 using my MBPr. But it worked! Whole process took about 12-13 mins.  Now I can listen to Tidal. Maybe it is due to Yosemite running on my laptop still. 

Hope that you will find a solution soon.

Stop bragging!!  Ha.  

I'm at my wits end.  I've tried 3 laptops, el capitain and yosemite and 1 PC with no joy at all.  Same error on each one which makes me think it is the cable that I have been using.  

You should be connecting your Mac to UQ via a USB cable. Have you done this?

I have the RS232 socket, not USB

RS232 can also be used for an update.

Maybe we have wires crossed....I am using the RS232 to update, as per my original post?

Apolgies - I misunderstood that you are trying the update via the network.

Are you using the latest updater 4.04.dmg?
Have you uninstalled the previous version?

Go to your system report and check if your USB Serial Converter is on.

I am using the latest updater on the Naim website yes.  I didn't have a previous version as I have just got the UnitiQute which was on 3.13 when I got it, so may have never been updated.

System Report?  What's that?

Ok - you need to 'prep' your Mac for uploading the software. 

When you've downloaded the updated from the NAIM website, there was a PDF document. It takes you step-by-step through the process of setting up your Mac to handle the uploads. It only needs to be done once.

Oh yes I have done that.  No sleep, check driver is installed etc...that was all good

The UQ2 has a mini-USB connection and seems trouble free. Older RS232 serial connections can be a bit finicky, especially on newer computers where a converter is required. Most people land on a solution after a hiccup then continue trouble free...but getting across the obstacle can be a bit frustrating. 

The latest OS X drivers from Prolific (the most common "older" USB to RS232 chip manufacturer) are v1.6.0 (released in October 2015) and are available for El Capitan (OS X 10.11, 64 bit).  There are new chips available from FTDI also, so be sure to download the driver for your cable / adapter. 

I wonder if there is any other diagnostic info you can share AlphaBeta? Can you see the USB interface choice in the drop down menu of the Naim firmware installer? Or are you shut out before then?

Then I can only think of two faulty areas (assuming your MacBook is working ok and has been set up correctly):

• Faulty cable
• Faulty RS232 port on your UQ.

I don't have the mini-USB so that is not an option  Frustrating would be an understatement.

I have installed the latest prolific drivers on all Macs tried and the Windows Laptop as well, still no joy.  Im convinced it is the cable.  If you click the link in my original post on R232 you will see the one I bought.  

Yep I can always see the controller in the drop down, that's not an issue.  It's just the part where it tries to communicate that it fails repeatedly

Hi again -

Sorry it is so frustrating! (Been there a million times...fortunately a vanishingly small number related to Naim gear haha). 

I can't see a link for an RS232 cable (and maybe it's in another thread, but I looked in "recent activity" in your profile and don't see it there either). It's true that there are a slew of pirate converters out there and it is a known issue that the drivers don't work properly with them...it is also true that cables are not as robust as they seem, so if it's damaged then it may not be totally obvious. 

I've just loaded the latest beta firmware on my SuperUniti (which comes with the mini USB) with zero issues. I'm about to go on a date-night dinner, but will bring the UnitiQute downstairs and see if I can start its update (and will report what I see, just in case that helps....but if you see the option in the Naim update program, I don't think your issue lies there!).

Regards alan

ps - if your old windows machine has an RS232 port on it, perhaps you could try with a straight serial cable (i.e. no converter necessary). That would give extra info, and keep you moving forward...

Hi again (again) -

I tried two different RS232-USB adapters and the one with Prolific drivers worked okay. In the drop down selection menu, it said usbserial at one point for one adapter (did not work; ftdi device) and failed as you said. At another point it said usbserial-fd400k (or similar - I can look again if useful) and it worked (prolific device). 

So I can confirm that a failure mode similar to yours with a functional able but a non-functional driver is possible. Also confirming that a successful upgrade using an adapter compatible with the new Prolific driver is possible. Lastly confirming that the SL adapter for the UART is not useful except for a USB-miniUSB cable (just in case you see / choose that in the drop down menu). 

Hope this helps.

Regards alan

In case it is interesting for somebody: I am using the Lindy RS232 USB serial cable to update my naim uniti 1. This did work fine with a Windows notebook as well with an MacBook Pro several times.

Just ordered a new lead coming tomorrow which will hopefully fix the problem!  Here's hoping anyway

I have a new lead now, an FTDI variation instead of prolific.  Still having the same issues though.  Perhaps issues with drivers.  The FTDI ones don't seem quite as straight forward
