I currently have OS 10.6 want to upgrade OS I currently have OS 10.6 - Safari and other browsers are no longer supported.
My problem is I have Adobe CS4 Design and web software and I don't have a few thousand dollars hanging about to upgrade CS4
SO.....
Does Lion work with Adobe CS4 - or should I just start saving my pennies for more expensive software?
I had heard that OS 10.6 was the highest OS I could get with CS4.
It looks like you can use CS4 with Mavericks according to Adobe's site.


  Is Adobe aware of any major issues, bugs, or odd user experiences when
  using CS5, CS4, or CS3 products with Mac OS X Mavericks (10.9)?
  
  Yes, Adobe Drive could cause the opening or saving of files to take
  longer. See Files open, save slowly for more information.
