Hi - I need some help, please. I have just a bought a new I Pad Mini (yes, I now know I should have waited - i have just found out that there is a new one coming out soon - oh well, hey ho !) and I also bought Microsoft's Office 365 as I am very familiar with Word and Excel spreadsheets and want to use it on the I-pad. I have registered my purchase on the Microsoft site and it tells me that I cannot use Office 365 as my Mac operating software is not up to date. It says I need MAC OSX 10.6. I check in Settings on my I-pad and it says I am running IOS 8.0.2 and that my software is up to date. So can you tell me what is going on here ? I am fairly new to Macs. What is the difference between MAC OSX and IOS ? Should I never have been sold Office 365 to run on the I-pad mini?
