They're still selling the SoundblasterX G6 so it's still a supported product, and they'll support it for a number of years after they stop selling it I imagine, so updates should be forthcoming for a few years yet I would have thought - in fact the Soundblaster Command Software was updated for it just a week or so ago (v3.5.10.0). I use it on Windows 11 on PC and it's totally fine and works properly, but I've never tried it on a Mac which is what you're talking about. For some reason on the Creative Soundblaster G6 web page they say that the G6 is supported on "PS4, Xbox One, Nintendo Switch, and PC", so they don't actually mention Mac in the text, however in a table lower down they do show Mac as being compatible, but yes in that table they say that the software doesn't work on the Mac so that means you have to set it up on PC first and then hook the device up to a Mac, which is not ideal - it's probably not the right product to buy if you've got a Mac. In the gaming sphere Macs just aren't popular or common, so for the target audience (gamers) it doesn't matter much that Mac is not as fully supported as PC when it comes to the SoundblasterX G6. If you're a gamer, which I'm guessing you are if you're considering a gaming DAC, then you'd probably be better off ditching the Mac and sorting yourself out with a PC/Windows based gaming option. Macs are overpriced & limited as a gaming platform.
I bought G6 for Xbox at 1st... then i finally used it for Windows because I have other DAC/Amp and had some problem with Xonar E.O Muses (with USB 3.0)
G6 wasn't really better than Mixamp (with or without Dolby Atmos Software) for FPS gaming.
Yes, Creative show a table with Mac and it say that "direct mode" is compatible but that's not true, i could do without the software but staying limited at 44.1khz that's really no sense when you have FLAC 24 bits collection... or Qobuz/Tidal HiFi option.
Lot of people complain about that, Creative know the situation and really don't care about support for old DAC because they sell newer DAC/amp now (like X5) which have the last software.. so they know you have to buy X5 if you want the update....
Asus did the same with Xonar E.O (any update since 2015 i guess), the Asus was better in my opinion (but no EQ/software)
You can't neglect Macbook (or iPad) they are best portable option since Apple Silicon ARM (M1, M2, M3...) which humiliate Intel... so Creative make a big mistake. Lot of people make the Windows>MacOs transition (and you can partially use Windows on Mac)
Best processor, great battery life, very low power consumption/efficiency, really noiseless (that's important when your computer is your musical source) and great power multitasking machine, mini Led screen, best loud speaker, awesome finish, Magsafe....
I have/ had expensive Dell XPS, Alienware, Asus OLED laptop etc... they simply can't compete with last Macbook for all (except gaming like you say but i don't play anymore on laptop and now you have cloud solution)
Windows laptop are transportable and not real portable too, battery life are always a joke.
High end laptop are now Macbook Pro... so when you spend lot of $$$ for HiFi, why neglect the best laptop on the market ? that's no sense, lot of "audiophile" have now a Mac...that's often the same customers... and that a "Windows" user since decades who wrote that...
