  1. Hi all, I'm sorry if this question has been asked a million times; I have spent some 4 hours searching the forums, Reddit, and using Google in search of what seemed to me to be a very simple question: how can I avoid having a 1-GByte-application running all the time, consuming what's left of my meagre resources, and still manage to have some functionality on my brand-new Void Elite USB headset? What I'm looking for is to run a very small daemon on my Mac which just provides enough information to the headset to tell it to remember the last settings (e.g. mic volume, side tone on/off, using bleeps or an informative voice, stereo or surround, etc. etc. etc.). I'm not even asking how to keep the lighting programming working without iCUE — I'm neither a gamer nor a modder, so I don't really care much about it, I've bought the headset for its legendary quality for voice chat, not for the nifty extra special effects. I understand now that some Corsair hardware have the option of getting configured under iCUE but there is an option to save such settings directly to the hardware. This is not the case for most hardware (including, I believe, the above-mentioned Void Elite USB headset), which relies on iCUE to continuously send commands to it (and read whatever sensors or input devices they might have). That's ok if you have a very complex lighting setup and have to deal with keyboard remapping and so forth, so there is no choice but to keep iCUE running all the time. But for my clearly underpowered Mac, having this colossal application (which takes about one minute just to load) just to have access to a handful of settings is absolutely wasteful. I've also learned that there is an SDK, as well as a few attempts to create a tiny webserver which accepts REST requests and converts them into SDK commands. That's all fine, and a credit to the awesome Corsair user community which is able to do such fantastic things, but... all of that still requires having iCUE running all the time and have the SDK slider turned on — which consumes even more resources! Isn't there a much simpler alternative? I've seen that the actual iCUE app is not very big (roughly 20 MBytes in size); what is huge is the Qt library that it requires to provide a minimally decent GUI (which, thanks to Qt, is consistent among platforms) — that's what takes around 1 GBytes. Because the iCUE application is not open-source (for very good reasons!) I cannot see if it works according to a client-server paradigm, i.e. if iCUE launches not only the GUI behemoth, but also a stub daemon which actually connects to the headset via USB. Perhaps that's what actually happens under the hood, but I cannot see how it works; I was searching inside the package contents for the iCUE application to see if I could find anything like that, but I admit my lack of knowledge about the Corsair/iCUE environment. It might be obvious, just not for me. Alternatively, are there other non-iCUE tools developed by Corsair that can accomplish the same, but without the GUI interface? Where can I download those? By now, I've learned that the official web site has some serious problems with outdated links, and that it takes some pain and a lot of patience to figure out where exactly the latest versions are being stored for download. So that's the reason why I may have missed that altogether. Last but not least... perhaps nobody thought of actually having such a ultra-light-weight daemon providing just the bare bones functionality that is exposed by iCUE; in that case, and beyond the SDK's own developer documents, are there any public (and preferrable official!) references about how to 'talk' directly to the headset, without the need of going through the iCUE application? Given some documentation, I believe I can cook up some very simple proof-of-concept, so long as I've got some information about how exactly the 'inner' API interface actually works...
  2. If you have the Homebrew package manager installed, just do: brew install corsair-icue A kind soul at Homebrew tries to keep up with the latest versions...
  3. By sheer chance, I found out that Homebrew now includes a cask for iCUE! If you have Homebrew installed, just do a brew install corsair-icue And that's just it — you'll get the latest version. Disclaimer: while the Homebrew crowd is rather good at doing their job to keep everything up-to-date and free of all sorts of malware, this is by no means an official channel for distributing Corsair software! As always, be wary of installing anything that didn't come directly from Corsair's own servers.
  4. I know it's bad manners to answer myself... but I did manage to download iCUE 4.12.214, which works flawlessly under macOS Big Sur. For your information, here is the link: https://downloads.corsair.com/Files/CUE/iCUE-4.12.214-release.dmg To figure this out, what I did was to take a look at the exact version number used by @Irish_Gent. Then it was just a question of figuring out the actual download links. These are relatively easy to figure out, by clicking on the download link for one of the 'old' versions, copying it, and changing the version number manually (that's why I needed to have a valid version number — it would be sheer insanity to try numbers in sequence in the hope of figuring out one that works) to what @Irish_Gent had on his screenshot. This downloads a fully functional 4.9 version — which will work perfectly under macOS Big Sur — and then it's just a question of auto-upgrading. At the time of writing, the update was to 4.12.214 — which can be directly downloaded as well, of course. I wonder what Corsair has against version 4.X for the Mac. Perhaps it has some hidden security flaws or bugs or something worse... who knows? My point is that version 3.X simply does not install under macOS Big Sur, and no, I don't wish to downgrade macOS (assuming it would be possible) just to install a version of iCUE to be able to change RGB colours on the headset...
  5. I'm afraid that as of today (June 24th, 2021) there is nothing more recent than 3.38.61. I'm attaching a snapshot of what I see after searching for Mac as suggested: Needless to say, v3.X will not work under macOS Big Sur... it refuses to install.
