How to Install Flash Player on Mac OS 10.3


Adobe Flash Player is software that is used for viewing videos and animation online through a web browser. One of the most widely distributed pieces of software, it originally wasn't compatible with operating systems Mac OSX 10.1-10.3. However, Adobe released an upgrade with a fix to the problem allowing Flash Player to be used with Mac OSX 10.3.9. Although it no longer appears on the front page of the downloads section, Adobe has an archive of previous software versions that work smoothly on the Mac operating system.

Things You'll Need

  • Mac OSX 10.3
  • Web browser
  • Go to the Adobe Flash Player archive (see Resources).

  • Download the link entitled Flash Player 9; it will be a .zip file containing all the archived versions of Flash Player 9, as various versions may work with varying operating systems.

  • Open the downloaded .zip file, and then open the file titled readme.txt. From the options listed, choose the correct Flash Player to match your operating system. Choosing the latest version of Flash is suggested to avoid bugs and other issues.

  • Open the proper folder containing the right version of Flash. There will be two .dmg files in that folder, one with "ub" in the name (as in "flashplayer9xxxx_ub_mac.dmg") and one without. Double-click the file with "ub" in the name and mount the disk image. Open the .pkg file and an installation program should load. This program will tell you how to install the Flash Player.

Tips & Warnings

  • If the Flash Player installer doesn't load in the last step, double-click the .dmg file without "ub" in the name. There you will see two files you can easily drag into the Internet Plug-ins folder, an alias of which will be in the folder that opens when you mount the disk image. These two files are entitled "Flash Player.plugin" and "flashplayer.xpt." Once both are in the plug-ins folder, Flash compatible websites and videos will load.
