DOWNLOAD Version 8.4.0
One binary. One kind of Mac.
Cutvey Offload is a native Apple Silicon Mac app: SwiftUI on a pure-Swift engine, with no third-party Swift packages. Everything that moves or verifies footage is written against Apple system frameworks, and the hash implementations are in the tree.

Opening it the first time
Open the disk image and drag Cutvey Offload to your Applications folder, then double-click it. That is the whole procedure. There is no right-click step and no Gatekeeper warning to click past.
The app is signed with an Apple Developer ID certificate issued to Cutvey and notarized by Apple, and the notarization ticket is stapled to both the disk image and the app inside it. Your Mac can therefore verify it without being online, which matters on a location shoot more than it does anywhere else.
Your Cutvey session and any saved S3 keys carry across an update. Nothing has to be re-entered.
You only need this page once. The app checks for updates itself and installs them in one click, verified against the published checksum.
01 Requirements
Apple Silicon, macOS 14 or later. That is the whole list.
There is no Intel build and there is no Windows version. That is a decision, not an omission, and it is not going to be revisited quietly at some later date, so it is worth being direct about it here rather than letting you find out after a download.
One architecture means one code path to make fast and one to make correct, and correctness is the entire pitch of this app. A second architecture would be a second set of behaviours to prove, on hardware nobody on this team is shipping on.
| Mac | Apple Silicon. No Intel build. |
| macOS | 14 or later. |
| Windows | Not available, and not planned. |
| Disk image | Roughly 27 MB. |
| Installed | Roughly 56 MB as an .app. |
| Account | A Cutvey account, free trial included. |
Most of that size is the bundled decode payload, and none of it is on the copy or verify path. It exists so camera reports can read and thumbnail footage the system cannot open on its own.
02 What is in the bundle
Only what the app actually calls.
Three third-party payloads ship inside the app so you never have to install an SDK. Everything they are not used for was removed, and that was verified rather than assumed: each component was taken out individually and re-tested against real clips, and the thumbnails hash byte-identical to a full-payload build.
| Component | Why it is there | Size |
|---|---|---|
| ffmpeg + ffprobe | Frame-grabber fallback for containers AVFoundation cannot open, notably Sony XAVC MXF. | ~24 MB |
| RED R3D runtime | .R3D metadata and thumbnails. CPU decode; the GPU and async decoder libraries are not shipped, because the app does not call them. | ~20 MB |
| Blackmagic RAW framework | .braw metadata and thumbnails. Shipped without its Metal, OpenCL and x86-only accelerators. | ~4 MB |
Leaving out what is not called saves roughly 31 MB. See the third-party notices for licences, ownership and the FFmpeg source offer.
What signing changed for your saved S3 keys
S3 secret access keys are stored in the macOS login Keychain, and the Keychain decides access based on the requesting app's code signature. Cutvey Offload is signed with a Developer ID certificate that does not change between releases, so the Keychain hands its items back after an update and your saved keys persist.
Why the app is not sandboxed
By design. It needs unrestricted disk access to read any mounted card and write offloads wherever you point them, it spawns a shell to run the event scripts you write, it opens connections to arbitrary S3 endpoints, and it stores secrets in the login Keychain. A sandboxed build would break all four. It is distributed outside the Mac App Store, so sandboxing is not required, and it ships with the hardened runtime enabled and notarized by Apple — which is the protection that actually applies to a distribution outside the store.

The trial gives you the Cutvey account the download is tied to, and it costs nothing to sit on until the build is up.
