OuchMac is a macOS menubar app that uses your MacBook's built-in accelerometer to detect physical impacts — bumps, slaps, drops — and plays a funny sound in response. It lives in your menubar and runs silently in the background.

Which Macs are compatible with OuchMac?

OuchMac works on MacBooks (Air and Pro) running macOS 13 Ventura or later that have a built-in accelerometer. Desktop Macs (Mac mini, Mac Pro, iMac) do not have an accelerometer and are not compatible.

How much does OuchMac cost?

OuchMac is a one-time purchase of $5 USD (approximately R$19.90 BRL). No subscription, no recurring fees. You pay once and own it forever, including all future updates.

What sound packs are included?

OuchMac includes 8 sound packs: Goat, Sexy, WTF, Fart, Classic, Retro, Cartoon, and Ghost. Each pack has multiple sounds that play randomly on impact for variety.

Does OuchMac slow down my Mac?

No. OuchMac is extremely lightweight. It uses less than 0.1% CPU at idle and only activates briefly when an impact is detected. It has no background network activity.

Can I adjust how sensitive OuchMac is?

Yes. OuchMac has a sensitivity slider in the menubar popover so you can tune how hard an impact needs to be to trigger a sound. Set it low for gentle taps, or high so only real slaps trigger it.

OuchMac vs SlapMac

Updated March 2026 · MacBook accelerometer sound apps

Overview

Two Mac apps. Both turn your MacBook's built-in accelerometer into a sound machine that reacts to physical impacts. Both live in your menubar. But they make different tradeoffs on price, compatibility, depth, and privacy. Here is everything you need to decide.

Pros & Cons

OuchMac

Pros

✓ $2 cheaper than SlapMac
✓ Works on macOS 12+ (vs. Sonoma 14.6+)
✓ No account required — just a license key
✓ Activates on 2 Macs, not just 1
✓ Lid open sound included
✓ 7-day money-back guarantee
✓ Confirmed macOS 15 Tahoe support
✓ Zero data collected, fully offline after activation

Cons

✗ Fewer total sounds (8 packs vs. 130+)
✗ No USB hardware trigger
✗ Custom sound import not yet available (coming v1.2)

SlapMac

Pros

✓ 130+ sounds — much more variety
✓ Custom sound import available now
✓ USB Moaner device for physical trigger

Cons

✗ $2 more expensive ($7)
✗ Requires macOS 14.6 Sonoma or later
✗ Requires account creation
✗ Single device activation only
✗ No lid open sound
✗ macOS 15 support unconfirmed

Pricing

Both are one-time purchases. OuchMac is $5, SlapMac is $7. The $2 difference sounds small, but OuchMac also covers 2 Macs per license while SlapMac limits you to one. Per device, OuchMac is significantly cheaper.

macOS Compatibility

OuchMac supports macOS 12 Monterey and later. SlapMac requires macOS 14.6 Sonoma — a hard cutoff for anyone on Ventura or Monterey. OuchMac also has confirmed macOS 15 Tahoe support. SlapMac has not published a compatibility statement for Tahoe as of March 2026.

Sound Library

SlapMac wins on volume: 130+ sounds vs. OuchMac's 8 packs. If variety is your priority, SlapMac has the edge. OuchMac's packs are hand-curated — Goat, Sexy, WTF, Fart, Classic, Retro, Cartoon, Ghost — each with 4–6 sounds that rotate randomly. Custom sound import is on the OuchMac v1.2 roadmap.

Privacy & Accounts

OuchMac requires no account. You get a license key by email and the app goes fully offline after activation. SlapMac requires account creation — your email and usage metadata are stored on their servers. If privacy matters, OuchMac is the clear pick.

Verdict: OuchMac wins for most users

OuchMac is cheaper, supports more macOS versions, requires no account, activates on two Macs, and includes a lid open sound. For most people who just want to slap their MacBook and get a reaction, OuchMac is the better pick.

SlapMac is worth considering if you need a massive sound library, already run Sonoma or Sequoia, or want the USB Moaner accessory. Otherwise, save the $2 and get OuchMac.
