I am very happy with its performance overall. Although the apps I use might be considered outdated--Photoshop 7, Indesign 2, Finale 2008--they work just fine for my needs. However, the browsers I use, Safari and Mozilla Firefox, cannot be updated and I get a lot of messages saying I am using a browser that is not supported. Question: (two fold) how difficult would it be to upgrade my machine to Leopard and, will it make that much difference in terms of compatibility? Thanks.<br><br>Jim Scarborough Kirk<br></div></span></blockquote><br></div><div>Jim Kirk? Really? Awesome. </div><div><br></div><div>Have you done any upgrades on the Quicksilver? Leopard is certainly possible on a Quicksilver, I have one sitting under my desk right now. Depending on your processor (800 vs. 933 MHz) you may not have to do any upgrades. Minimum specs for Leopard are here:</div><div><br></div><div><a href="http://support.apple.com/kb/HT3759?viewlocale=en_US&locale=en_US">http://support.apple.com/kb/HT3759?viewlocale=en_US&locale=en_US</a></div><div><br></div><div>To get the full benefit I'd upgrade your processor and probably the video card as well, here's what mine looks like:</div><div><br></div><div>1.8 GHz processor</div><div>1.5GB RAM</div><div>ATI Radeon 8500</div><div>USB 2.0 Upgrade Card</div><br></body></html>
