macbook mac OS X 10.5.8 ?

Hi,

Flash Player has not been supported on OSX 10.5.8 for several years.  The last release was 10.3.183.90 and the installer is posted on the Archived Adobe Flash Player versions (direct link: Flash Player 10.3.183.90 - Mac only).  While this is the last version to be released for OS X 10.5.8 it's very likely that most modern browsers will block it, and some content you attempt to view will require a newer version of Flash Player) due to it being so old, not to mention it has not received any security updates to address any vulnerabilities found, and fixed, after its release.

If you have an Intel-based system it may be possible to upgrade to OS X 10.6  (Snow Leopard) and install the latest version of Flash Player.  Performing an internet search for "upgrade 10.5.8 to 10.6" will return many results on this.  You'll of course need to ensure the system is upgradeable and that you have enough RAM to run OS X 10.6 (if not, you may need to add more RAM, if possible).  Several things to consider, but if it's possible, upgrading to 10.6 would enable you to install the latest most secure version.
