Intel or Apple Silicon Mac: Which Build Should You Download?
On this page
Mac downloads come in pairs: one build for Intel, one for Apple Silicon. Pick the right one and everything just works; pick the wrong one and you get either a refusal to launch or an app quietly running slower than it should. The split exists because Apple changed the processor architecture underneath macOS — and knowing which side of that change your Mac sits on takes about ten seconds to check.
This guide covers the Intel vs Apple Silicon distinction as it applies to proxy software: how to identify your chip, which package name maps to which Mac, and what actually happens when the wrong build lands on your machine.
Two Mac eras since 2020
Until 2020, every Mac shipped with an Intel processor using the x86_64 architecture. Starting in 2020, Apple began moving the lineup to its own M-series chips — M1 and its successors — built on the arm64 architecture. The two instruction sets are not interchangeable: a program compiled for one cannot natively run on the other. Apple ships a translation layer, Rosetta 2, that lets most Intel apps run on Apple Silicon anyway, but translation is a compatibility bridge, not a reason to choose the wrong build on purpose.
Check which chip your Mac has
- Click the Apple menu in the top-left corner of the screen.
- Choose About This Mac.
- Read the chip line: "Chip: Apple M1/M2/M3…" means Apple Silicon; "Processor: Intel…" means Intel. (Layout differs a little across macOS versions, but one of those two lines is always there.)
Which build maps to which Mac
Different projects label the same two architectures differently, which causes most of the confusion. The mapping for everything on our download center:
| App | Intel Mac | Apple Silicon Mac |
|---|---|---|
| Clash Verge Rev 2.5.2 | Intel / x64 dmg | Apple Silicon / aarch64 dmg |
| mihomo v1.19.29 | amd64 build | arm64 build |
| FlClash 0.8.94 | Intel dmg | Apple Silicon dmg |
The rule underneath the labels: Intel = x64 = amd64 = x86_64, and Apple Silicon = arm64 = aarch64. Same architecture, different naming conventions — once you see the equivalence, every download page becomes readable. The CPU architecture guide extends this decoding to Windows, Linux and Android.
What happens if you pick the wrong one
- arm64 build on an Intel Mac: it will not run, full stop. Intel Macs have no translation layer for ARM code. The symptom is usually an immediate "cannot be opened" style failure.
- Intel build on an Apple Silicon Mac: it usually runs — macOS offers to install Rosetta 2 on first launch and translates the app from then on. It costs some performance and battery compared to the native build, so treat it as a stopgap and switch to the arm64 package when convenient.
Tip: if an app misbehaves strangely on an M-series Mac, check whether you accidentally installed the Intel build months ago — running translated without realizing it is common.
Note that a launch failure on macOS can also be the unrelated Gatekeeper "damaged" warning; the full first-run sequence, with both issues in context, is in the macOS install guide.
Frequently asked questions
What is a "universal" build?
A universal binary packages both architectures in one file: each Mac runs its native half. It is the convenient option when a project offers it, at the cost of a larger download. Where separate Intel and Apple Silicon packages are provided instead — as with the apps above — picking your architecture gets you the same result in a smaller file.
How do I install Rosetta 2?
You do not seek it out: the first time an Intel-only app launches on Apple Silicon, macOS prompts to install Rosetta and handles it in a few seconds. If you stick to native arm64 builds, you may never need it at all.
Does the native build make the proxy faster?
Native code avoids translation overhead, so the client runs leaner — but your actual browsing speed depends on the server and your connection, not on this choice. Pick native for efficiency, not in expectation of higher bandwidth.
