Is the M1 actually faster or is this marketing bullshit?

The [M1 is genuinely fast](https://www.apple.com/newsroom/2020/11/apple-unleashes-m1/) for single-core stuff, which is more important than you'd think. Built on 5nm with everything crammed onto one chip - CPU, GPU, and all the other bits. Single-core performance destroys Intel, multi-core depends on what you're doing.

I'm a developer - will this break all my tools?

Docker was a nightmare at launch but works now. I spent two hours debugging why my containers were slow as shit before realizing I was running x86 images on ARM. `docker buildx build --platform linux/arm64` became my most-typed command.Node.js, Python, VS Code, Git - all work fine. The shit that breaks is usually abandoned garbage anyway. Though MongoDB Compass took forever to get ARM support and I had to use the web UI like a caveman.

Can I still procrastinate with Chrome and 47 open tabs?

Chrome still eats RAM like usual, but the unified memory helps. 8GB M1 feels like 16GB Intel because there's no overhead copying data around. Still, if you're a tab hoarder developer who runs Docker and keeps Slack open, get 16GB to be safe.

What about running old Intel apps?

[Rosetta 2 translation](https://support.apple.com/en-us/HT211861) works surprisingly well. Most Intel apps run at 70-80% of their native speed, but the M1's single-core is so good that translated apps often feel faster than they did on Intel Macs anyway. The weird part is some translated apps actually run better on M1 than they did on Intel hardware.

What's actually broken on M1?

The main gotchas: - **No Windows Boot Camp**: Gone forever, use Parallels for ARM Windows if you need it - **x86 VMs are slow**: Running Intel/AMD VMs through emulation is painful - **Some dev tools**: Check if your specific toolchain has ARM versions - **Gaming**: Most games don't run natively, emulation is hit or miss - **External monitors**: Only one 6K display, multi-monitor setups are limited Most stuff works now, but if your workflow depends on any of these, think twice.

Can I run iPhone apps on my Mac?

Yeah, some iOS apps show up in the Mac App Store and they're surprisingly decent. Procreate works well with a trackpad for basic sketching. Most developers don't bother putting their iOS apps on Mac though, so don't expect your favorite mobile game.

Should I get 8GB or 16GB?

For normal use, 8GB is fine because of the unified memory efficiency. But if you're a developer running Docker, multiple browsers, Slack, and whatever other resource hogs, get 16GB. You can't upgrade later - it's all soldered down.

External monitor situation?

This sucks - only one external 6K display plus the built-in screen. Intel Macs could drive multiple monitors, but M1 is limited. There are workarounds using DisplayLink adapters but they're janky and use software rendering. **Monitor limitation reality:** M1 = 1 external display max. Intel Macs = usually 2-4 external displays. If you need multiple monitors, this is a dealbreaker.

7-core vs 8-core GPU - does it matter?

Base models get 7-core GPU, upgraded models get 8-core. It's about 10-15% difference in graphics performance. Unless you're doing GPU-intensive work, you won't notice. Both are the same chip - Apple just disables one GPU core in the cheaper version.

Forget about it. The integrated graphics are decent but most games don't run natively on macOS, and translation layers like CrossOver are hit or miss. Stick to consoles for gaming, use M1 for everything else.

How long will Apple support M1?

Apple usually supports Macs for 7-10 years. M1 launched in 2020, so expect updates until at least 2027-2030. Given how well it performs, probably longer. Don't worry about obsolescence anytime soon.

Can I upgrade anything later?

Nope. RAM and storage are soldered to the motherboard. Choose wisely at purchase time because you're stuck with it forever. This is the biggest downside - no "I'll upgrade later" safety net.

Does it get hot and loud?

MacBook Air has no fan and stays silent even under load, which still feels like magic. MacBook Pro and Mac mini have fans but they barely run. After years of Intel laptops that sounded like jet engines, the silence is wonderful. **Thermal performance:** M1 MacBook Air = completely fanless, never hot. Intel MacBooks = fan constantly spinning, hot enough to cook on.

Boot Camp is dead forever on Apple Silicon. You can run ARM versions of Windows in Parallels, but compatibility with x86 Windows software is sketchy. If you need Windows regularly, stick with Intel or get a separate PC.

Common problems I should know about?

Early M1s were buggy as hell: - WiFi would randomly disconnect and reconnect every 30 minutes (fixed in macOS 11.2) - My Logitech MX Master 3 mouse was jittery and laggy until they released proper drivers - External monitors would wake up showing garbage pixels - had to unplug and replug constantly - Docker Desktop 3.0.0 was completely broken on M1, took them months to fix it By 2025 most of this shit is fixed, but early adopters got fucked for six months.
