Your OM System camera, operated from the Mac. Live view you can trust, the exposure rail under your fingers, and the shutter one keystroke away.
OM System makes some of the best cameras in photography — and asks you to drive them from a phone app nobody enjoys. These cameras speak a capable HTTP protocol over their own WiFi; what has been missing is a considered Mac app on top of it. Remote for OM System is that app: native, fast, and built around three functions done completely — See, Control, Shoot.
No app chrome over the frame. The image is the interface: live view fills the window at 30 frames per second, about a tenth of a second behind the lens, with the exposure rail on one side and the levels on the other. Everything else stays out of the way until it's news.
The best camera tool is one that disappears.
See. Live view at 1024×768, 30 fps, roughly 100 ms glass-to-glass — a real viewfinder, not a laggy thumbnail. Click the frame to place focus. Live levels and a focus meter that climbs exactly where the image is sharpest, so manual focus stops being a guess.
Control. The exposure properties the camera exposes over WiFi — mode, shutter, aperture, ISO, exposure compensation, white balance, drive — on one rail. Click a value or scroll to step it; the rail greys out what the current mode won't allow, and the metered readouts ride the video stream itself, at frame rate. Save any setup as a named recipe and recall it with ⌘1–⌘9: unlimited presets, exportable, each one showing how far the camera has drifted from it and reverting in a keystroke — where the body gives you four opaque custom slots.
Shoot. Space fires the shutter. The frame comes back as a review toast — carrying a quiet focus confirmed when the camera says it locked — and press I to open the shot at 1:1, landed on the point you focused, with focus peaking a keystroke away and the exposure the camera actually recorded in the header. The loop is fire → inspect → adjust → fire — without touching the camera, without leaving the app. And when the camera declines a shot because focus never locked, it says so: a refusal reads as a refusal, not as a dead shutter.
A self-timer and intervalometer with a room-legible countdown and audio ticks. On-device subject detection that keeps focus on you — face, torso, or hands — as you move. An onion-skin ghost of a reference frame for repeating a composition. Work in front of the lens without running back to the tripod.
Every feature exists to help you take the next photograph — focus, expose, fire, check, adjust. It is not a file-transfer tool or a catalog; your card reader and your DAM already do that better. One job, done completely.
No account, no analytics, no internet. The app talks to your camera and nothing else. These bodies quietly substitute a value they can't take — ask for ƒ5.6, get ƒ3.5, and say nothing about it. The app trusts only what it reads back, and tells you: camera set ƒ3.5. When something can't work — a mode the camera won't allow, a macOS setting silently blocking the connection — the app says so, names the cause, and walks you to the fix.
Built and field-proven on the OM System OM-1, and verified on the E-M1 Mark I, E-M1 Mark II and E-M5 Mark II — the WiFi protocol holds three generations back, and the app adapts its whole interface to whatever your body reports: its drive modes, its exposure modes, its enums. If you shoot another WiFi-capable OM System or Olympus body, chances are good it just works. And if it doesn't, Help ▸ Save Camera Report writes one file in which your camera describes itself — model, modes, the values it accepts, the dialect it speaks, serial numbers stripped before anything is written. That file is how a body gets onto this list. Requires macOS 15.6 (Sequoia) or later.
