To make any website fill the entire screen, which is a little ridiculous on an iMac with a 27" screen, just grab the bottom right corner and make the page as large as you want it.
Alternatively, click the Green button at the top of the page and Safari will automatically adjust the size of the page to that of the website.
Using the Green button method, you do not get all the white space at each side of the page.
Go to Safari Preferences > Advanced and change the minimum font size to something larger
Go to the Adobe site and download the Flash uninstaller. Once you have run it and Flash has been removed, download and install the latest version of Flash from the Adobe sight.
Imac OX 10.6.1. When opening yahoo or any website, it does not occupy the full screen like it does in a PC. As for fonts in websites, is there any way to make its appreance look bigger which will be easier on eyes. After a security update, unable to view youtube and video. Downloaded adobe flash player 188.8.131.52 & still unsucessful. Found a old flash file in the trash. Is it usable & if so how or is there any particular version to download? Any advise appreciated.
