Determining Your Mac Type

Before downloading, you need to identify your Mac's processor type:

Apple Silicon Macs (M1, M2, M3, M4 series)

• Released 2020 or later
• Check: Apple Menu → About This Mac → look for "Apple M1", "Apple M2", etc.
• Or run in Terminal: uname -m (returns "arm64")

Intel Macs

• Released before 2020 (and some 2020 models)
• Check: Apple Menu → About This Mac → look for "Intel" processor
• Or run in Terminal: uname -m (returns "x86_64")

Download Steps

1. Visit codexeditor.app
2. Click the macOS button at the top of the page
3. Select your Mac type from the dropdown:
   • Apple Silicon - for M1, M2, M3, M4 Macs
   • Intel - for older Intel-based Macs
4. The download will begin automatically

Installation Process

1. Once downloaded, open the .dmg file
2. Drag Codex Editor to your Applications folder

Download Steps

1. Visit codexeditor.app
2. Click the Windows button at the top of the page
3. The download will start automatically (x64.exe file)

Installation Process

1. Locate the downloaded .exe file (usually in Downloads folder)
2. Double-click to run the installer
3. Important: You may see Windows security warnings

Handling Windows Security (Unsigned Application)

Windows may show security warnings because the application isn't code-signed:

1. SmartScreen Warning: If you see "Windows protected your PC"
   • Click "More info"
   • Click "Run anyway"
2. User Account Control: Allow the installer to make changes
3. Follow the installation wizard prompts

What "Unsigned" Means: The application doesn't have a digital signature from a recognized certificate authority (aka Microsoft). Windows flags this as potentially risky, but it's safe to proceed.

Determining Your Architecture

Before downloading, identify your system architecture:

uname -m

Common Results:

• x86_64 → Choose x64
• aarch64 → Choose arm64
• armv7l → Choose armhf

Download Steps

1. Visit codexeditor.app
2. Click the Linux button at the top of the page
3. Select your architecture from the dropdown:
   • x64 - Most common for desktop/laptop computers
   • arm64 - For 64-bit ARM processors (like Raspberry Pi 4, Apple Silicon via emulation)
   • armhf - For 32-bit ARM processors (older Raspberry Pi models)

Installation Process

The exact installation method depends on the package format provided:

For .deb packages (Ubuntu/Debian):

sudo dpkg -i codex-editor*.deb
sudo apt-get install -f  # Fix dependencies if needed

For .AppImage files:

chmod +x codex-editor*.AppImage
./codex-editor*.AppImage

For .tar.gz archives:

cd codex-editor

Handling Linux Security (Unsigned Application)

Linux systems may require additional permissions:

1. Executable Permissions: You may need to make the file executable

   chmod +x codex-editor

2. Package Manager Warnings: Some package managers may warn about unsigned packages

   • This is normal for applications not in official repositories
   • Proceed with installation when prompted

What "Unsigned" Means: The package isn't signed with a recognized GPG key or distributed through official repositories. This is common for third-party applications.
