Installation

Download the latest version for your platform:

• macOS: EP-PatchStudio_macOS_universal.dmg (Intel and Apple Silicon)
• Windows: EP-PatchStudio_Windows_x64_installer.exe
• Linux: .deb, .rpm, or .AppImage

Only download from official sources: this website, or the GitHub releases page.

macOS Gatekeeper blocks unsigned applications. You'll see an error like: "EP-PatchStudio.app" can't be opened because it is from an unidentified developer.

Method 1: Right-Click Open (Recommended)

1. Double-click the DMG to mount it
2. Drag EP-PatchStudio.app to your Applications folder
3. Right-click (or Control+click) on EP-PatchStudio.app in Applications
4. Select "Open" from the context menu
5. Click "Open" in the security dialogue
6. The app will now open and macOS will remember your choice

Method 2: System Settings (macOS 13+)

1. Try to open the app normally (it will be blocked)
2. Open System Settings → Privacy & Security
3. Scroll to the Security section
4. Click "Open Anyway" next to the EP-PatchStudio message
5. Enter your password if prompted

Method 3: Terminal (Advanced)

Remove the quarantine attribute:

Troubleshooting macOS

• "The application is damaged" — Run the xattr command above, or re-download the DMG
• "Application already open" — Quit completely (Cmd+Q) and try again

Windows Defender SmartScreen blocks unsigned executables. You'll see: Windows protected your PC

Installation Steps

1. Double-click the installer
2. SmartScreen appears — click "More info" (small text link)
3. Click "Run anyway"
4. Follow the installation wizard
5. If UAC appears, click "Yes"

The first time you run EP-PatchStudio from the Start Menu, SmartScreen may appear again. Click "More info" → "Run anyway".

Troubleshooting Windows

• "This app can't run on your PC" — You may have downloaded the wrong architecture. EP-PatchStudio requires Windows 10 x64 or later.
• "Access denied" during install — Right-click the installer → "Run as administrator"
• "Windows Defender blocked this app" — Open Windows Security → Virus & threat protection → Protection history → Find EP-PatchStudio → Actions → "Allow on device"

Linux distributions generally don't enforce code signing for desktop applications.

Debian/Ubuntu (.deb package)

AppImage (Universal)

RPM-based (Fedora, RHEL, openSUSE)

Code signing verifies the publisher's identity and ensures software hasn't been tampered with. It requires purchasing certificates (Apple Developer ID costs $99/year, Microsoft Authenticode $200-400/year).

For beta testing, pre-release and initial release, I'm distributing unsigned builds to keep costs down and iterate quickly. I do plan to implement code siging in a future release.

Yes, if you downloaded from an official source.

Unsigned ≠ unsafe. It just means I haven't paid for a code signing certificate yet. You can verify the app's integrity by:

• Checking the SHA-256 file hash (provided with downloads)
• Scanning with antivirus if you're concerned
