Understanding Legacy Compatibility and Limitations
Explains the feasibility and severe risks of attempting to run Acrobat 9 and CS3 on macOS 10.6.8.
While installation of Acrobat 9 Pro might technically complete on older Mac systems like OS X Snow Leopard (10.6.8), it is not officially supported. More importantly, Creative Suite 3 has reached its end of life, and Adobe has permanently shut down the activation servers.
Visit the Adobe Help Center via your web browser to review the legacy system requirements. You will find that Adobe Reader and Acrobat 9 are listed as unsupported.
If you launch the CS3 installer and attempt to enter your serial number in the activation dialog, the process will fail because the required legacy authentication servers are permanently offline.
Understand that using Acrobat 9 poses significant security risks. Do not use it to open untrusted PDF documents, as the software no longer receives critical security patches to protect against malware.

Transitioning to Supported Software
Move away from obsolete applications to ensure a secure and functional document editing environment.
