Wow! I was very surprised by the big number of feedback I got when asking tips for my new MacBook! I'd like to say you a big THANK YOU! You are great.
I already installed iStat Pro. I liked it very much.
I also installed Adium, NoeOffice, Transmission, Songbird and I'm still downloading and installing other suggestions.
One drawback I saw was that after installing some applications, my solid rock brand new MacBook started to hang when shutting down! :O
I uninstalled iStat Pro as I think it is the only low level thing which could give me this type of problem. Until now, I already shut down my laptop two times and the problem seems to be solved. I installed the 4.6 version on my OSX 10.5.3.
I will try another version or a previous one later.
I don't now but I didn't like the SongBird. I don't know why yet. I liked very much the Rhythmbox and I'm sad I can't get it on my Mac :(. For while I think I will keep using iTunes. But I'd rather use some other open source audio player.
I followed the suggestion of creating a new folder inside the Applications special place. (This makes me ask: Is there a way to add other folders to the Places together with my home folder and the applications folder itself?)
I also put this folder near the trashcan in the dock so I can access it easily. I just couldn't use the long click where I could see the hierarchical list of applications through menus. Maybe I need more explanation?? :) Anyway,thank you for your excellent explanations of many other aspects related about OSX. I didn't know I would need to be so cautious about software updates.
Another problem I had was that OSX seemed to not recognize my wireless keyboard correctly. It is an ABNT2 Brazilian Portuguese keyboard. When I connected it it showed me some keyboard options but I couldn't get my ç key to work on it. :( Maybe I'm doing something wrong. I will try again later.
Another problem I faced was when using my external LCD television. It has a resolution of 1360x768 and I couldn't use mirror with native screen resolution. I only could use it with extended desktop. I'd like to be able to turn off laptop lcd and just use the external monitor. Is this possible? A friend of mine said I could close the laptop lid but I think this could make my macbook heat up.
Other than that, everything seems to be working very well. I will post here more things I find about OSX.
Again, I'd like to thank everybody who spent some time to read my post and comment it. Thank you very much! I'm a much happier Mac user now. :)
That's it. See you!
P.S.: Thanks for the Pratchett quote indication. :) I hope my sanity is not so in danger because of so many exclamation marks. Just to be sure, I used fewer ones this time :)
