I am running OSX 10.9.4 (Mavericks) on a Retina Macbook Pro, l have a brokers software that depends on java. l am currently running java version: 1.6.0_65, do l just go to http://support.apple.com/kb/DL1573 to download update 17? which is the latest version? when l had a pc l was instructed to uninstall the old java version first. do we have to do this with mac? if so how?
