Hi in august 2012 I recently got a refurbished 13" i5 october 2011 moddel Pro with 4gb ram click here so far things have been going well. I love mac and how easy it is to use. Its been great. I got a free upgrade to Mountain Lion. I have come from Mainly Linux over the past 3 years so I like using multi desktops. I use between 3-5 desktops. running browser(chrome), messaging(adium), email(thunderbird), music(itunes), office(libreoffice). I notice at times i get slight hangups. with the curser loading wheel. I was told this was to do with the new multi desktop feature. My friend who has been using mac for a while said the first multi desktop idea in osx snow leopard ran much better than in lion, mountain lion. Also as I understand that mac does not need much maintenance just like linux. is it really worth using memory, cache, temporary file cleaners or does mac do a good job of this itself. I hear that when uninstalling an app sometimes not all files are removed. is there a way to remove application and all associated files. In linux sometimes a terminal command is needed to remove the app and user files. Is there any app like idvd, now that is no longer available, to copy and create dvds with nice menues etc. What app do i need if i want to tripple boot mac, windows, linux. at the moment i have vbox installed and run linux and windows there. would be nice to have full booting especially for gaming in windows. any other tips and tricks for a new user that you might think is good for me to know or understand. I thank you for taking the time to read and apply to this post. Happy Mac using all.
