Thank you for reporting this, but unfortunately I doubt this is solvable by code.

The problem is the one mentioned in the error message: the update software failed to connect to the internet to get the list.
More precisely, it failed to read the webpage https://fw.simntonic.com/ - can you try this in a browser? It should write something like "DEVICEIDLIST:..."

This could be caused by a firewall blocking the access, maybe the page is cached wrongly (then refresh in your browser and then try again) or maybe your mac has not given permission to the app to access the internet (if so you would get a popup asking you for the permission usually).

Alternatively, can you try the upgrade using the Config Tool or the U-SYNC Daemon. They use exactly the same library to update your Nome, but if it's a permissions issue then they might have the right permission.

With the url in Safari I do get the following..

DEVICEIDLIST:1:midronome;16:nome2

But none of the Simntonic apps can get there. I'll try on a different Mac, on my old Mac Pro it finds in, on the new Mac mini M4 it's not, Firewall was turned off.

What permissions should your apps have access to? I have seen no popup to give access.

Had this same issue-- Using the U-Sync Daemon worked for me!!

Huh interesting - I'll investigate. Thanks for the info!

Thanks for the info. Would you mind trying again on the normal update software? If it works it will simply say that you are up to date.

@Custa1200 -> unfortunately I cannot reproduce this at all, I tried on multiple machines all on macOS 15.5. Do you have any "unusual" setting for Internet, like a VPN or a proxy?
The app does the same as Safari, really

Regarding the permissions, that was just a guess - on all my tests I've never had to give access. But could you maybe go to the System Settings > Privacy & Security and look around there if you see any warning or if you see that the app is blocked somehow.

But in any case - you could upgrade using your old Mac Pro, right?

Anyone solve this?
I'm on am M2 Mac and I'm running a KS version of Midronome, but I can't update FW and the Config app won't run as I'm on old FW and it throws the same error when you ask it to update FW.
I'm stuck?

Hi This sounds like a different issue - or do you get the same error message?

If you have an old firmware (3.0 or older), you will need to update the bootloader first . The software update tool should inform you about that but maybe the "failed to download firmware list" issue happens before it has time to check your Midronome.

I get exactly the same error. Identical.
I'm on FW v4. Update again?
I have run the update procedure and when the Midronome has UPG on screen I run U-Sync / Update and get exactly the same error.
I'm on a Mac on OSX 15.5 (24F74)

[Simon]

Oh I see - then yes on FW 4.0 you already have the new bootloader.
And yes the error should be the same on the U-SYNC Daemon or using the Updater or even the Config Tool - they all use the same mechanism for the update.

I will continue the efforts in investigating this, it's partcularly difficult since I cannot reproduce the issue at all, on any of the machines I have here.

I assume that just like for the others, the page https://fw.simntonic.com/ loads fine for you too?

[Simon]

I get exactly the same error. Identical.

Could you please check your firewall settings and your antivirus settings?
When you go in "Privacy & Security" on MacOS settings, do you see anything at the bottom (like "this application has been blocked")?

And how do you run the App - directly from the dmg file or did you copy it into a local folder first?

Thank you
Simon

EDIT: please check as well if you are using a VPN, and in Settings > Network > Your network (for example "Wi-Fi") > Details > Proxies, check that no Proxy is setup.

[Duffdaddy]

No security issues, nothing blocked. App is installed on HD, not running from DMG. No antivirus or proxy running.
I can access the FW link in my browser too, so that's not at issue.

Thanks for checking (note that on all my tests the tool runs fine when run directly from the DMG - but I thought it was worth a shot).

I'm very sorry about this, I've tried many different machines and configuration and I cannot reproduce it at all.
I've also investigated a lot, trying to "blind guess" what the issue could be. I've made a new version for you, which you can download here.

This version has a small change which could be the issue (from the blind guessing), so if we are very lucky the problem is gone.
If not could you please try the following:

1. Copy the .app in your Downloads folder
2. Then open the Terminal app, and type (including the quotes):

   Code: Select all

   "./Downloads/Sim_n Tonic Firmware Update.app/Contents/MacOS/Sim_n Tonic Firmware Update" 

3. Then try to update as you did before

This will launch the app from the terminal and the terminal will show you the log with a bit more information. Could you please copy/paste what it writes?

Thank you

[Duffdaddy]

I've solved this by doing the update on my PC. Just wouldn't work on my MacBook and I can't find out why. Sorry.

That's more than fair - sorry about this.

Cool cool. Very frustrating. Especially when there's no obvious reason.
Had a similar issue recently with the new install of Reason 13. Just wouldn't run.
Turned out the updated version of ReCycle was causing Reason to fail to launch, even if you didn't have ReCycle running.
There was a patch for ReCycle that fixed it but could I find this anywhere on their site. Nope. Facebook User group was the solution.

Just received the Nome II and wish it would come with latest firmware but ok! Downloaded firmware updater and it can’t retrieve the list of updates (says I should check my internet connection - which is fine) what now? Thank you.

Same issue when trying to update via the U-Sync Daemon

Hi Fabrice, thanks for asking on the Forums!

I thought this problem was gone, but it seems it is not! It's a big mystery, I cannot reproduce it on 4 different macs with different OS versions, it seems to be that macOS somehow blocks the internet access to the software.
Can you try the solution suggested above?

Thank you
Simon

[fabricemil]

Thanks Simon, no dice unfortunately.

UPD: I finally was able to update the FW with a windows machine. Sorry can't really explain why it doesn't work on mac. Tried different macs with no luck.

My Nome II arrived today (yay). Unfortunately it has come with firmware 3.1, and I can't update it, with the same error as these previous messages posted here by users.

I've followed everything in this thread:
- I can reach https://fw.simntonic.com/ via my browser
- I have downloaded the 1.3.1 firmware update linked to on this page
- I have tried two different Macs (both on MacOS Sequoia 15.6)

Sorry about this - if you can wait a few days, we will very soon release a new version of the tool with an offline update possibility

[Duffdaddy]

Totally, can always wait for a good thing : )

[GunCharlie]

Exactly the same issue here, brand new unit ($500AUD) Mac Mini M4 Sequoia 15.2, Sync Daemon indicates a connected unit, flash tool fails, bootloader fails. This is very disappointing.

[Simon]

Hi all

Apologies for the troubles.

This is now fixed and released in the latest version (1.4.0) of the Firmware Update tool - https://download.simntonic.com/software ... -1.4.0.dmg

The fix is not present in the U-SYNC Daemon or in the Sim'n Tonic Config tool, a new version of both of these (with the fix) will be released next month together with Firmware 5.0.

Simon


PS: the issue should be fixed but more importantly the tool now also has an "offline" mode where you can update your Nome even without an internet connection. This mode will only be available on the Firmware Update tool.
