Is there a genuinely free auto clicker for Mac?

Yes. AutoClick is free and native, and free scripting routes exist too — Hammerspoon, cliclick, and built-in AppleScript. Many "free" App Store tappers are freemium with paid features.

Is OP Auto Clicker available for Mac?

No. OP Auto Clicker is Windows-only and relies on a Windows API that does not exist on macOS. Running it on a Mac would require a Windows virtual machine.

Is MurGaa Auto Clicker free?

It is a free trial, not free. The trial is limited and you pay to unlock it. Call it shareware rather than a free app.

Do these work on Apple Silicon?

Native tools like AutoClick run on Apple Silicon and Intel as a universal binary. Windows-only tools do not run without emulation.

Best Free Auto Clickers for Mac

“Free auto clicker for Mac” hides a lot of asterisks. Some tools are free to download but paywall the useful parts. Some are free trials that expire. And some of the most-searched names are not Mac apps at all. Here is the landscape, sorted by what “free” really means for each.

Genuinely free and native

These run on macOS as actual free software.

AutoClick. Free, native universal binary for Apple Silicon and Intel. Records clicks, keystrokes, scrolls and drags, replays them a set number of times or on a loop, supports global F6/F7/F8 hotkeys, and collects no data. Built for the record-and-replay job specifically. (That’s this app.)
Hammerspoon. Free and open source, scripted in Lua. Enormously capable for automation in general, but you are writing code, so it suits power users more than someone who just wants to click a button repeatedly.
cliclick. A free command-line tool you install through Homebrew. It clicks at coordinates with delays and is great inside scripts, less so if you want a window and buttons.

Built in and free, but limited

AppleScript and Automator ship with macOS at no cost. AppleScript can click exact coordinates; Automator can wrap it. Both are fragile — fixed coordinates, awkward looping, hard to stop — and need Accessibility permission. Fine for a quick one-off, frustrating for daily use. (More on the built-in options in does Mac have a built-in auto clicker?.)

Free trial, then paid

MurGaa Auto Clicker. Native and capable, but it is shareware: the trial is limited and you pay to unlock continued use. Useful to know if you went looking for a “free” download and hit a registration screen. If you want a no-cost alternative, that is the gap AutoClick fills.

Freemium, despite the listing

Mac App Store “auto clicker” and “tapper” apps. A crowded category, and many are free to install but lock the features you want behind in-app purchases. They are sandboxed and reviewed, which is reassuring, but read the in-app purchase list before assuming “free” means free.

Not on Mac at all

OP Auto Clicker is Windows-only. It depends on a Windows input API that macOS does not have, so there is no native Mac build — running it would mean a Windows virtual machine. If you searched for it expecting a Mac download, that is why you could not find one. A native Mac alternative is the practical route.
AutoHotkey, often suggested alongside it, is likewise Windows-only.

Paid, for context

If you outgrow free, Keyboard Maestro and BetterTouchTool are polished paid macros-and-automation tools, and Macro Recorder is a paid cross-platform option. None are free, but they are honest about it.

How to choose

For most people who want to click a spot repeatedly or replay a short sequence, a free native app is the simplest answer — no scripting, no trial timer, no emulation. Look for three things: it runs natively on your chip, it has a clear global stop hotkey, and it does not phone home. AutoClick was built to check those boxes, but whatever you pick, verify it is genuinely free and comes from a source you trust.
