How to install Adobe Illustrator CC 2020 on Mac (pre‑exclusive guide)

Note: This post assumes you have a legitimate Adobe Creative Cloud subscription or a valid license for Illustrator CC 2020. Do not use pirated software.

Part 5: Finalizing Your Pre-Exclusive Setup

Once Illustrator launches without demanding a login, you have a fully functional pre-exclusive copy. However, to keep it working for years:

Do’s:

• ✅ Disable automatic macOS updates (especially security patches that reset hosts).
• ✅ Keep a backup of the original DMG and the patched .app on an external drive.
• ✅ Install plugins manually via /Applications/Adobe Illustrator 2020/Plug-ins.localized/

Don’ts:

• ❌ Never click "Update" inside Illustrator.
• ❌ Never sign into Adobe Fonts or Adobe Stock from this version.
• ❌ Do not run the official "Creative Cloud Cleaner" tool.

2.3 Critical Preparations

1. Uninstall previous Adobe versions using Adobe Creative Cloud Cleaner Tool.
2. Disable SIP (System Integrity Protection) – required for many pre-exclusive installers:
   • Restart Mac → hold Cmd + R → Utilities → Terminal → type csrutil disable → reboot.
3. Block Adobe hosts (optional but recommended to prevent deactivation):
   • Add to /etc/hosts:
     127.0.0.1 lmlicenses.wip4.adobe.com
127.0.0.1 activate.adobe.com

4.1 First Launch

• Keep Wi-Fi ON but ensure firewall blocks Illustrator.
• If a "Sign in" window appears → close it. The app should still launch.
• If it crashes on launch:
  Reset preferences by holding Cmd + Opt + Shift + Ctrl while starting Illustrator.

✅ Legitimate use cases:

• Professional print shops running macOS 10.15 on air-gapped Intel Macs with legacy plugins (e.g., Esko, Cimetrics).
• Archivists needing to open very old .AI files that corrupt in newer versions.
• Offline-only environments (e.g., research vessels, military) where cloud auth is impossible.

Step 3: Block Adobe Validation Servers (via Hosts File)

Open Terminal and type:

sudo nano /etc/hosts

Add these lines at the bottom:

127.0.0.1 lmlicenses.wip4.adobe.com
127.0.0.1 lm.licenses.adobe.com
127.0.0.1 na1r.services.adobe.com
127.0.0.1 hlrcv.stage.adobe.com

Press Control + O → Enter → Control + X to save. install adobe illustrator cc 2020 on mac pre exclusive

Step 2 — Install via Creative Cloud app

1. Launch the Creative Cloud desktop app and sign in if prompted.
2. Click the Apps tab.
3. Search for “Illustrator.” By default Creative Cloud shows the latest version. To install CC 2020:
   • Click the three-dot menu next to “Open” or “Install” for Illustrator and choose “Other Versions.”
   • From the list, find “Illustrator CC 2020” and click Install.
4. Follow on‑screen prompts. The installer downloads files and installs automatically. Allow macOS permissions if requests appear.
