Hi there, I am new to my mac - loving it - just a little daunting! I have been sent some files from friends and work to read, but when I go to open them, it looks like Alien language. There is nothing that I can use to read the files. Please can any of you help? Is there some kind of software that I can purchase or download to open these files, which would be the equivalent to word, excel, etc? As there is nothing like that on here. Thanks.
