Hello! I have an imac 21.5-inch (late 2009) on my table with OS X El Capitan running on it. It has the following specifications: 1. Processor - 3.06 Ghz Intel Core 2 Duo 2. RAM - 8 Gb 3. Graphic card with 256 Mb I have not been able to update the OS to run most recent Applications, and most of it, the web browsers are not updating as well. What should I do to get through? Thank you.
