Thanks, I hate it: Someone installed macOS on a Steam Deck

By Alex Blake October 21, 2022

Yesterday we got the news that Apple might bring macOS to the iPad Pro. Today, someone has managed to get macOS to run on a Steam Deck. And tomorrow? I’m betting we’ll see macOS installed on a toaster. You heard it here first.

Back to the Steam Deck. The feat was achieved by enterprising Reddit user Lampa183, who apparently was able to get macOS Catalina running inside a VirtualBox virtual machine on their device. In other words, this is several layers of operating systems and emulation. But the result is worth it … right?

Well, according to Lampa183, performance on the Steam Deck is “normal” with macOS Catalina installed. However, they added that “some animations are [laggy] and turning on takes 2 to 4 minutes.” So, this is probably not the most monstrous Steam Deck out there in terms of raw power.

When asked what was working and what was not, Lampa183 responded that the device could access the internet and that the touchscreen was “partially” working. On the other hand, “Sound, GPU and (for some reason) security settings” were out of order.

I suppose we shouldn’t be too picky at this stage, since getting a full desktop operating system to work on a Steam Deck — something both the software and the hardware were entirely unprepared for — is an impressive feat in itself.

It’s not the first time macOS has found itself on an unfamiliar device. We’ve seen Apple’s old-school System 7 installed on a graphical calculator. There’s an entire cottage industry of people running macOS on custom PC hardware, crafting machines called “Hackintoshes.” And if you combine Apple’s Sidecar and Universal Control features, you can even get macOS to run almost natively on an iPad.

Still, I think running macOS on a Steam Deck takes the biscuit for now. Even if it is buggy and half-baked, it’s more daring than anything I’d ever try.

How to choose between a MacBook and a Windows laptop

The keyboard and trackpad of the MacBook Pro.

When shopping for a new laptop one of the biggest decisions you'll make is choosing between MacBooks or Windows laptops. And it's not always an easy decision. New advances in chip technology are propelling even entry-level MacBooks to high-performance targets, and a shift in Windows laptops away from cheap plastics evens the playing field between these two platforms. Both Windows 11 and macOS are intuitive and clean operating systems. But where they differ comes down to one key element: their ecosystems.

What this means for you is that choosing an option from a list of the best laptops isn't so simple. The laptop you choose today can greatly influence which accessories you buy, which apps you use, and even what kind of phone you carry. Your entire workflow will depend on the platform you go with, from how you manage windows to which keyboard shortcuts work best. It's not a light decision.

The new iPad Pro would be perfect, if only it were a Mac

It’s no secret that I’ve been cheering on Apple’s gaming advances over the last year or so. Long-suffering Mac gamers have gone from being the forgotten also-rans of Apple’s ecosystem to feeling on top of the world, all in a very short period of time. But there’s one vital piece missing from the puzzle, and Apple’s new M4 iPad Pros have made it incredibly obvious.

I’ll admit, Mac gamers have been treated well in recent times. Not only have we had phenomenal hardware advancements in the form of the M3 Max chip -- which is a genuine gaming chip so cool and quiet that you’d be fooled into thinking it’s not -- but there’s also been a slate of top-tier games arriving on Apple’s platform, including my beloved Baldur’s Gate 3. It’s a good time to be a Mac gamer.
