I just updated my iMac with the new update 10.5.7. So far no issues.
Like previous updates, this updates the general OS. Enhances the stability, compatibility and security of the OS. There is no added functionality or new features.
It is rumored that this is the last update before Snow Leopard is released later this year. So far this is the most stable OS I have worked with. I am not naming names but you can figure out whom I am speaking about.
I am looking forward to the Iphone update later this summer.
Apple just keeps on improving on something that is already perfection…
