What is disk visualization tool? It’s a software that let you easily and graphically see what is in your disk. I’ve used Disk Inventory X on mac for long time. It’s free and helpful when I want to see what hog my harddisk space. By the way, I’m switching to DaisyDisk ($20), another disk visualization tool for mac in the market.

This topic was reported by PC Magazine. I didn’t read all the detail but the only first paragraph, and that’s enough for me to hold off on updating to Leopard 10.5.6. (only the topic is enough actually) I’ll wait and see how Apple handles this problem. v10.5.7 could be soon to come.
