I updated my Mac Mini this past weekend to Tiger (OS 10.4). Wow, who would have though going from 10.3 to 10.4 would have made the machine run so much better. I was pleased before but am even happier now. I do hate that I had to pay $100 for the upgrade as I purchased the machine back in February.
I upgraded my 12″ PowerBook recently. It too runs well. But, on that machine, I’ve installed Norton Anti-Virus. Seems these types of apps require a lot of CPU and in turn cause it to heat up. And when that happens, the fan runs, a lot! So, I’m running naked on the Mini and no fan. On the PowerBook? The fan runs a lot. I’m going to go from 512MB of RAM to 1.25GB and see what happens. On my 15″ PowerBook, I have 1GB of RAM and it seems the fan never runs, even with Norton.
