Issues installing usb driver in OSX

Evan Scheele posted:

I guess I must be a glutton for punishment, but I dug out my wife’s MacBook Air running 10.10.5, figuring I might as well give it a try on a THIRD Mac.  Same as before; System sees the driver and the naim installer doesn’t.

Sigh.

 

Maybe strange question: did you check "security & privacy" - " general " setting - if the driver hasn't been blocked by the computer?

So, I did get the 4.6 upgrade to work after some hours of research and effort with an RS232 port, no usb on my NDX (older NDX I guess) I'm posting here, in case it helps anyone. I know this has been mentioned in passing but there were two key things that allowed my upgrade to work.

Firstly, after the first reboot after installing the driver, I had to go to system preferences\security & privacy immediately. There it showed that MacOS was blocking the driver, I had to click "allow" so the system would load the driver. If you do not do this it seems it stays in "disabled software" forever. You can see disabled software in about this Mac \ system report near the bottom of the list. Once the driver was "allowed" I was able to get a serial port to do the upgrade. 

I'll point out here that the previously the serial cable appeared to be installed, it was visible in system report \ usb but without the driver fully loaded it could not function and provide a port.

The second part I had to get right was timing with the NaimUpdater app. Even though I had serial port available the process with NDX would say "not communicating" This started working when I restarted the NDX and as soon as I turned it on I hit retry on the app. I had previously tried this 10 or more times unsuccessfully. For some reason timing was everything. 

No it shouldn't be this hard, I work in tech, and the fact I couldn't get this going annoyed me so kept at it. Hope this helps someone get this going. 

That looks like great advice Hedgebre. I possibly did what you suggest in a frenzy of 'try different things in desperation' mode and just got lucky with my eventual update.

Evan, suggest you try the above, seems like it could work for you.

The Update is very worthwhile on sonic grounds so would urge all to persevere.

Hello, Chaps!

Happy to report that I’ve finally  had success installing 4.6!  I installed OSX10.13 on my wife’s ancient MacBook Air, and somehow, that did the trick!  And to think that it only took three machines and four different operating systems to get there!! What could be easier?

;-)

Will report on sound quality on the other thread after I breathe into a paper bag for a while...

Thanks for all of your support and helpful counsel.

Regards,

Evan

See Evan, it's simple! Well done and I will be interested to hear your views on changes/improvements in SQ.

Cheers, nigelb!  

Will post further, in the appropriate thread, but I already have some initial thoughts on the sound of 4.6 on the 272:

Much more open, bigger, deeper, soundstage with better separation of instruments and voices; no loss of PRAT; noticeably more relaxed and confident sounding overall; much better timbre and decay on cymbals, etc.; slightly fuller bass presentation, but I’m not noticing any of the bloat that some have reported, but my active Atc 40’s are a sealed design and have notoriously tight and tuneful bass; might be different with a ported design. Also, the presentation to me feels a bit less etched and more organic.  (My bullshit attempt at describing the presentation of the music, over now, mercifully.)

Very pleased so far.  Had to turn the 555PS DR off and on again briefly and from experience, I know that has a bit of a sonic penalty associated with it for 72 hours or so, so it’s early days, as you guys say over there.  So we’ll see.

Hope others are enjoying 4.6 as well.

Regards to you all,

Evan

I installed the Serial/USB driver on my MacBook Pro several times.  Each time it was reported as successful but didn't show up in the list.  There was no Disabled Software message blocking the driver, and rebooting didn't change the appearance of the driver in the list.  I tried on my PC but the driver wouldn't install because a suitable driver for my machine was apparently not found.

Anyway, I just thought I'd try the update and see what happens.  A Driver appeared in the list as "SLAB_USBtoUART" as expected, and the update proceeded as set out in the instructions without problem.  

Slightly frustrating to have wasted so much time trying to see the driver, but perhaps others might find just moving on successful too.

@Judge - Yes, I had the same experience using an old MacBook Pro, running El Capitan (version 10.11.6) per my post of yesteday

Well, I've just installed the 4.6 streamer update onto my NDS, via my MacBook Pro, so I'll mention here how I went about it, just in case there's anyone out there stuck in  a rut.

Previous attempts to update  firmware didn't go well, since the required SiLabs USB driver wouldn't show up in the "about this Mac" window, so I had to resort to asking my dealer to perform the update.

This time, "same old same old", no sign of the driver, although the Silabs downloader insisted, as above, that it had been successful downloaded and installed.

Nevertheless, I decided to press on, and opened the Naim downloader / installer, where the first window asks the user to choose the required Com port, and, blow me down, there it is, listed as "Uart Controller".

With fingers crossed, I initiated the download process, and, some twenty minutes later, version 4.6.00 is now running on the NDS.

A couple of words of caution though, do not stare at your laptop screen, checking on the download / upload / install process, (or is it only me who does that?), without keeping an eye on the screen on your NDS.

At the end of each process, 100% success is reported, and everything seem to have completed .............. but no, don't touch anything!

After a minute or so, the NDS will display "DSPDAC Update - please wait"

An updated progress window will appear on your Mac, and again will complete to 100%, and again will appear to stall for a minute, before the NDS display changes to "Streamer Update - please wait".

It's slightly strange to me that these "don't touch" warnings appear solely on the NDS, as, viewing the Naim downloader, it would be so easy to take "100% success" as implying completion, or, as above, again, is that just me?

Anyhow, Is there any improvement in SQ?

Far too early to say, as I'm presently collapsed on the sofa, breathing gently into a paper bag.

Phew!

Same thing with the completed message on a PC, even though the streamer is still chuntering away doing stuff. But I suspect that the updater programme has finished and the streamer is doing stuff with the data you sent it, so it wouldn't matter if you did shut down the PC.

Having said that, I did the same as you and left the PC alone until the streamers had restarted and were ready for use!

Hello,

Didn’t have time to read all of these posts, but if you have a later MacOS (10.13 is current), the operating system deliberately stops the driver from running as it isn’t trusted.  I had this problem, which sounds a lot like the orginal issue, when using a USB cable to my NDX (not serial adapter) but it’s not Naim’s fault.

Try “Apple” menu -> “System Preferences” -> “Security & Privacy”. On the “general” tab, you might see a notice that SiLabs software (from an unidentified developer) has been blocked (at the bottom).  There should be an “open anyway” button to allow it to run. Restart the Naim Updater app and see if that pesky driver isn’t listed!

I'm using macOS High Sierra 10.13.4. I followed the instructions as included in the download and the whole thing was completed in 16 minutes. I did have to close the "system report" tab and open it again for the driver to be visible after installing it. I updated an NDS using a MacBook Pro (13-inch, 2016). At least for my part it went super smooth!
