Download for Mac How to install

Version 0.1.3 · Apple Silicon · macOS 14+ · ZIP

01

Your Mac

Built for Apple Silicon (M1 or newer). Requires macOS Sonoma 14 or later. An Intel build is not available yet.

02

Node.js first

Custapp uses Node.js for its local workspace. Install Node.js LTS before opening the app.

03

A preview build

This build is ad-hoc signed and is not notarized. macOS may ask you to allow this specific app on first launch.

FROM DOWNLOAD TO WORKSPACE

Three steps. Then build.

  1. Download and unpack

    Download the ZIP and open it in Finder. Move Custapp.app to your Applications folder.

  2. Open Custapp

    Open the app from Applications. If macOS blocks it, follow the first-launch instructions below. Configure your AI provider and workspace in Settings.

  3. Choose how you work

    Build directly on your Mac, connect through Custapp Web, or follow the PSP setup guide. PSP hosting and the bundled PSP client are included. In Settings → PSP Companion, choose Install on PSP… or Set up PPSSPP.

macOS says the app cannot be opened

Attempt to open Custapp once. In System Settings → Privacy & Security, use Open Anyway for Custapp, then confirm Open. This allows this app only. Do not disable Gatekeeper system-wide.

Verify your download

Compare the downloaded ZIP with the published SHA-256 checksum. Release details include the exact source commit, requirements, signing status, and file size.

MAC + PSP

Your Mac does the heavy lifting.

The PSP preview sends prompts to your Mac. Set up Wi-Fi pairing or manual USB exchange, including PSP Street.
