My best suggestion to fill that time with fun would be to check out the game demos and freeware you can obtain within the Games category of the Downloads section of the apple.com website.
Apple is constantly uploading recent game software updates, beta’s, limited play demo’s, and freeware titles for your enjoyment.
There’s nothing like access to free software to enhance your computing experience!
Game subcategories include:
Action & Adventure
Cards & Puzzle
Demos & Updates
Kids & Learning
RPG & Strategy
Simulation & Sports
Utilities
Here’s a fun freeware game to start you out called Microbop;
Because everyone wants a chance to pilot a microscopic jet-powered vacuum cleaner!
Have fun!!
