Installing Nativeline

Getting started with Nativeline takes just a few minutes. Download, install, and you’re ready to build.

​
Before You Start

macOS 15.1+

Sequoia or later required. Check via → About This Mac.

Internet Connection

Required for AI features and downloading dependencies.
That’s it. Nativeline automatically installs everything else you need on first launch — including Xcode, iOS Simulator, and all development tools.

​
Download and Install

1

Visit nativeline.ai

Go to nativeline.ai and click the Download button.
2

Open the DMG

Once downloaded, double-click the .dmg file to open it.
3

Drag to Applications

Drag the Nativeline icon to your Applications folder.
4

Launch Nativeline

Open Nativeline from your Applications folder or Spotlight (Cmd+Space, type “Nativeline”).
If you see a security warning saying the app is from an unidentified developer, right-click the app and select “Open” to bypass Gatekeeper for the first launch.

​
First Launch

When you open Nativeline for the first time, everything you need is installed automatically.

​
Automatic Setup

Nativeline downloads and installs all required development tools:
  • Xcode — Apple’s developer tools (~12GB)
  • Command Line Tools — Build utilities
  • iOS Simulator — For testing your apps
This happens automatically in the background. You’ll see progress indicators as components are installed.
First launch takes longer due to downloading Xcode (~12GB). Make sure you have a stable internet connection and at least 20GB of free disk space.

​
What You’ll See

  1. Progress indicators as Xcode downloads
  2. Brief welcome animation introducing Nativeline
  3. Home page when setup is complete
Once setup finishes, you’re ready to start building.

​
The Home Page

After setup, you’ll land on the Home Page where you can:
  • Create a new app — Start a fresh project
  • Open existing projects — Continue where you left off
  • Access account settings — Manage your plan and preferences

Troubleshooting Installation

This is a macOS security feature. To open anyway:
  1. Right-click (or Control-click) on the Nativeline app
  2. Select Open from the menu
  3. Click Open in the dialog that appears
You only need to do this once.
If the automatic setup seems stuck:
  1. Check your internet connection — Xcode is a ~12GB download
  2. Make sure you have at least 20GB free disk space
  3. Restart Nativeline and let it retry
  4. Contact support@nativeline.ai if it continues to fail
Try these steps:
  1. Make sure you’re running macOS 15.1 or later
  2. Delete and re-download the app from nativeline.ai
  3. Check Console.app for error messages
  4. Contact support@nativeline.ai with the crash report
If Xcode fails to download:
  1. Check your internet connection
  2. Try a wired connection if possible (large download)
  3. Ensure you have 20GB+ free space
  4. Restart your Mac and try again
  5. Contact support if persistent
Nativeline requires about 20GB of free space for Xcode and the iOS Simulator. Free up space by:
  1. Emptying Trash
  2. Removing unused applications
  3. Clearing Downloads folder
  4. Using Storage Management (Apple Menu → About This Mac → Storage → Manage)
