I have the Mac Book for me and this is the first time I have got an Apple laptop for me. I am little bit uncomfortable with the User Interface of the operating system that it has. Well as the time will pass I am sure that I will be used to the UI. Now the thing is that when I was using the Acer Aspire I was having the Windows XP SP 3 on it and then I switched to this laptop. Well in the previous one I was having the Mozilla Firefox browser and I really loved the same. I want that thing on the MacBook too is it really possible to have the same thing. However if it is not possible then can I have at least the Internet Explorer instead. I am finding the browsers of the Mac Book also uncomfortable. Please suggest me on this particular topic. Is there going to be any security issues with the same and hence I should avoid them. Please suggest me appropriate solutions. Waiting for the replies from your side. Hope that I will receive suggestions soon.
