I have a workhorse of a MacPro built in early 2008. I can not afford a new Mac at the time, and this does everything I need it to except get to important websites such as iCloud, Square, YouTube, and various banks because the browsers are out dated.
I have been told Lion is the most-up-to date macOS I can install.
Is there a newer browser that is still supported by the websites above that can be installed on this mac.
Is there an Newer OS that can be installed **Must be compatible with Adobe CS3 or CS4
Please include helpful links if you know of any.
