PCB Design Software for Mac: Native, Browser, or Windows-Only

Native on macOS: install it like any other Mac app

KiCad publishes one universal DMG for macOS 12 and newer, so the same download covers Intel and Apple Silicon Macs. The KiCad project officially supports the three most recent major macOS versions; older releases may still run but fall outside official support, and a community MacPorts port exists for people on unsupported releases. It is open source under GPL v3 and includes schematic capture, PCB layout and ngspice simulation.

Autodesk Fusion is a native Apple silicon application with macOS 14 Sonoma as its minimum, though Autodesk notes some commands still ask for Rosetta 2. Electronics design lives inside Fusion next to the mechanical CAD, which is the reason to choose it if you design the enclosure too. The free personal-use license is for non-commercial projects by individuals generating less than $1,000 USD a year and has limited electronics and PCB features. The full license is $680 per year or $85 per month.

LibrePCB 2.1.1 offers separate Intel and Apple Silicon DMGs for macOS 10.14 and newer, and its site says it has no costs, no restrictions and needs no online account. DipTrace offers a macOS download for 10.15.4 and later; its download page does not say whether the Mac build runs natively on Apple Silicon. Its freeware edition is limited to 300 pins and 2 signal layers.

Browser-based: works on any Mac, owns nothing locally

Flux runs entirely in the browser. Its entry plan is $50 a month when billed monthly, with a 14-day trial. After the trial, Flux says a free account can still interact with public projects, but editing private projects, exporting and using AI need a paid plan. Because projects live in Flux's cloud, nothing about your Mac's chip or macOS version matters beyond having a current browser.

EasyEDA covers both routes. Its online editor (Std and Pro) runs in the browser, and the Pro edition (v3.2.206) also has a desktop client for macOS 11 and newer with both Intel x64 and Apple arm64 builds. The older Std desktop client is Intel x64 only, so on an M-series Mac use Pro or the browser. EasyEDA's download page labels the Pro edition free.

Windows-only tools: Altium, OrCAD and Proteus on a Mac

Altium Designer recommends Windows 11 (64-bit), and Altium states that running it on virtual machines and emulators is not supported. Cadence lists only 64-bit Windows 10 and 11 and Windows Server for OrCAD X. Labcenter lists Windows 10 as the minimum for Proteus and says ARM processors such as Snapdragon are not supported.

That last point matters on Apple Silicon. Microsoft's supported route for Windows 11 on M-series Macs is Parallels Desktop running the Arm versions of Windows 11 Pro and Enterprise, or a Windows 365 Cloud PC streamed to the Mac. Inside the Arm VM, x64 applications run under emulation. So an x64 EDA suite in Parallels on an M-series Mac falls outside what Altium supports, and outside Labcenter's stated processor support for Proteus.

If one of these tools is mandatory for your job or your course, plan on a Windows PC or a Windows 365 Cloud PC rather than counting on a local VM.

Choosing by the kind of work you do on the Mac

If you want free software and project files on your own disk, KiCad and LibrePCB are the native options, and KiCad adds ngspice simulation in the same suite. If the board has to fit a housing you are modeling at the same time, Fusion keeps both in one place. If you want board ordering close to the editor, EasyEDA advertises a one-click ordering service and links out to LCSC for parts and JLCPCB for prototypes. If you want a shared project in the browser with AI help and are fine paying monthly, Flux fits.

If your employer or customer standardizes on Altium or OrCAD, the Mac question becomes an IT question: get Windows hardware for that work and keep a native tool for everything else.

Where ProtoFlow fits on a Mac

ProtoFlow is a native desktop app for macOS, Windows and Linux, and its download page lists a universal build for macOS 11 or later on Apple Silicon or Intel Macs. Design files stay on your disk. It drafts an editable schematic from a plain-language prompt with real LCSC, DigiKey and Mouser parts, then gives you schematic, symbol and footprint editors, ERC, PCB layout with an auto-router, DRC, a 3D view, ngspice simulation, and Gerber X2, drill, BOM and placement output. It imports KiCad, Altium and EAGLE projects, which helps when a Windows colleague sends you an Altium design.
