Unreal Engine 5 Still Doesn't Play Nice With

Here's a weird disconnect that tells you something about the state of professional creative software in 2025: You can run Blender, Maya, ZBrush, Cinema 4D, and even Unity on an Apple Silicon Mac without breaking a sweat. But Unreal Engine 5—arguably the most prominent real-time 3D engine in the world—still crashes more often than it renders.

Adam from the Adam Doing Tech YouTube channel documents this peculiar situation across multiple M-series machines, from the M1 to the M4, including the Pro and Max variants. His experience isn't an edge case or a configuration problem. It's the consistent story: Unreal Engine 5 on macOS is unreliable in a way that its competitors simply aren't.

The Professional 3D Toolkit Works Fine

Adam's workflow spans most of the major 3D creation tools. He's finished projects in Maya on an M1 MacBook Pro, an M1 MacBook Air, and an M4 MacBook Air. Cinema 4D delivered completed work without issues. ZBrush runs clean. Red Shift renders without complaint. Even Mari—which doesn't exactly have the largest user base—works as expected.

This matters because it establishes a baseline. The problem isn't Apple Silicon's architecture or macOS's ability to handle demanding 3D workloads. The hardware and OS can clearly support professional creative work at the highest levels. Unity, Epic's direct competitor in the game engine space, runs on macOS "without any issues," according to Adam.

So what's going on with Unreal?

Native Support That Doesn't Actually Work

Here's the frustrating part: Unreal Engine 5 has native Apple Silicon support. This isn't a Rosetta 2 translation layer problem. Epic made the port. It should work.

But as Adam demonstrates in his video, launching a project becomes a lottery. "As you can see as soon as I open the project it just crashes and it never goes through," he explains while attempting to load Unreal. "I think it opened only once or twice and now it did a crash as well."

Once or twice. Out of how many attempts? That's not software with bugs—that's software that fundamentally doesn't work reliably enough for production use.

And crucially, Adam notes this isn't tied to a specific chip generation: "It's not like related to the M1 or the M2 or M3 or M4 or even the M Pros or the M Maxes or even the M Ultra. It's not about that."

When a problem spans every configuration of a hardware platform, you're looking at something systemic.

When Reliability Matters More Than Performance

There's a particular kind of frustration that comes from tools that work most of the time. Adam captures it perfectly: "Opening once or twice and then it crashing most of the time. That is not a very reliable situation to be in especially if you want to finish something. Not necessarily provide like or deliver that something to a client. Just in a general sense you want to create something because you are feeling creative today in that case you need the machine to work."

This hits at something important about professional creative work. Raw performance benchmarks matter, but reliability matters more. A machine that renders 10% faster but crashes 50% of the time is worse than useless—it's actively destructive to creative momentum and client deliverables.

For hobbyists experimenting with Unreal on a Mac, occasional crashes might be tolerable. For professionals with deadlines? "Sadly if you are using Unreal Engine and you want to depend heavily with Unreal Engine on Mac OS it's not reliable and I cannot recommend it," Adam says flatly.

The Epic-Apple Relationship Question

There's an elephant in the room here, and it has tusks shaped like App Store commission disputes. Epic and Apple have been in legal battles over App Store policies since 2020. While that fight was primarily about Fortnite and mobile platforms, it's hard not to wonder whether the relationship between these two companies affects macOS development priorities.

To be clear: Adam doesn't speculate about this, and neither should we without evidence. But it's worth noting that Unity—Epic's competitor—seems to have macOS working just fine. So do all the other major 3D software packages.

Adam expresses hope that "Apple and Epic they would do more conversations and then they would get us to a point where it's actually reliable to use Unreal Engine on Mac OS." The word "conversations" is doing interesting work there. It suggests that whatever the problem is, it's not purely technical—it's also organizational.

The Broader Pattern of Platform Support

I've watched platform support drama play out for three decades now. Sometimes it's about market share—companies prioritize the platforms where their users are. Sometimes it's about architecture—porting engines across different hardware paradigms is genuinely hard. And sometimes it's about corporate relationships and strategic priorities.

What's unusual here is the isolation. Unreal Engine 5 works on Windows. It works on Linux. It technically has native macOS support. But that macOS support doesn't deliver the reliability that every other major 3D package manages on the same hardware.

That's not a market share problem—the same market exists for all these tools. It's not an architecture problem—Apple Silicon is clearly capable. Which leaves us with priorities, resources, and relationships.

Where This Leaves Mac Users

Adam's advice is unambiguous: "As it stands right now in 2025, I will say steer away from Mac OS if your main tool is Unreal Engine."

That's a tough position for anyone who's already invested in the Apple ecosystem or who relies on macOS for other parts of their workflow. The M-series chips are genuinely impressive pieces of hardware. For most creative work, they deliver exceptional performance and battery life.

But if your work centers on Unreal Engine 5, you need a different platform. Not because the Mac can't handle it—the evidence suggests it absolutely could—but because Epic hasn't made it work reliably. Whether that's due to technical challenges, resource allocation, or corporate dynamics, the practical result is the same.

What's striking is how clearly the rest of the 3D software ecosystem has embraced Apple Silicon. When Blender, Maya, Cinema 4D, ZBrush, and Unity all work smoothly on the same hardware where Unreal Engine crashes repeatedly, that tells you something. The question is whether Epic and Apple care enough to fix it.
