Hi guys, I have a (silly) question, excuse it. I bought my Macbook 13" last year and it came with Tiger pre-installed. Am I eligible for a free upgrade to Leopard or should I purchase the Upgrade pack? And, one more doubt... There are few softwares that, after installing them, remains only till I reboot and then vaishes. Everytime after I reboot, I have to reinstall them all to use them - Yahoo Messenger, Audicity for instance. Any solutions??? Thanks, dollarsai.
