There isn’t much you can do with it in its current form, but that may change in the future.
Valve announced in August that it would allow other PC-based handheld manufacturers to use its Steam Deck operating system, the Linux-based SteamOS, once it was satisfied. The team is currently making sure that the system is compatible with as many devices as possible, but of course the modder community is not idle either.
Recently, after long experimentation, the whatdahopper X-user managed to get Apple’s latest desktop operating system working on Valve’s handheld console – even if it doesn’t have much practical use at the moment.
As you know, the handheld is not yet capable of GPU acceleration in this form, however, this may change in the future with the arrival of the AMD Van Gogh iGPU kext (kernel extension). macOS already supports RDNA 2, which means that the handheld console can become a true portable Hackintosh in the future.
Of course, the game will not be as comfortable on it as on Windows or Linux systems, so it is not worth installing macOS for that reason alone.
with the help of some people (CorpNewt, among others), we got macOS going on the Steam Deck.
took awhile, but we figured out a fix to make OS’s newer than catalina boot, and so, here is the macOS Sequoia recovery running on Steam Deck… pic.twitter.com/0PfqOGoQIp
