How to Install OmniSeps — AIO Installer Guide

The OmniSeps AIO Installer bundles everything you need in a single file — no manual downloading, no dragging files around. This guide walks you through the full installation on both Windows and Mac.

What's Included

The AIO installer automatically installs:

• OmniSeps — Color separation plugin for Photoshop
• OmniChange — Extension for Illustrator
• OmniColor — Color profile for Photoshop & Illustrator
• OmniPanel — Illustrator workspace layout
• OmniKeys — Illustrator keyboard shortcuts

Before You Begin

⚠️ Close Photoshop and Illustrator before running the installer. Installing while they are open may cause errors.

Enable Additional Plug-ins Folder in Illustrator

This step is required for OmniChange to appear in Illustrator. Without it, the extension will not show up under Window → Extensions even after a successful install.

On Mac: Illustrator → Preferences → Plug-ins & Scratch Disks

On Windows: Edit → Preferences → Plug-ins & Scratch Disks

Check "Additional Plug-ins Folder" → click OK → restart Illustrator.

Installation — Windows

1. Download OmniAIO-Win.bat
2. Double-click the file
3. If Windows shows a security prompt, click "More info" → "Run anyway"
4. If prompted, click "Run as Administrator"
5. The installer menu will appear — select 3: Install All to install everything at once
6. If stuck on Installing OmniColor, wait 5–10 seconds. If it's still stuck, press Enter to continue

Installation — Mac

1. Download OmniAIO-Mac.sh
2. Open Terminal (press ⌘ + Space, type Terminal, press Enter)
3. Drag the OmniAIO-Mac.sh file into the Terminal window
4. Press Enter
5. Enter your Mac password if prompted (it won't be visible while you type — this is normal)
6. The installer menu will appear — select 3: Install All

💡 Tip: If Mac says the file can't be opened because it's from an unidentified developer, go to System Settings → Privacy & Security and click "Allow Anyway".

After Installation

Troubleshooting

Try restarting Photoshop. If it still doesn't appear, re-run the installer and choose Install OmniSeps from the menu.
