Hello everyone. I recently purchased a new aluminum macbook (my 1st mac) and had a few questions related to maintenance and upkeep. I've read a lot of articles/posts/etc and have decided to do the following to help maintain my mac. Please post your thoughts, other suggestions, etc. I appreciate it... I'm going to install iantivirus for protection and macjanitor as my computer will likely never be on 24/7. I'd also like to DL a p2p such as limewire, but am not sure what the best free option out there is on mac. Also, how often do you check for updates? Is there anything else I should be doing that I didn't list? I read that defrags and cleanups arent necessary, esp with the use of macjanitor. Is this accurate? For the battery, I'm assuming it's suggested not to keep it plugged in all the time - simply charge it up and unplug until a charge is needed again, right? Again, please let me know what you think. I appreciate it!
