Hello everyone new to the forums here I hope someone can help me out. OK so I recently bought an IMac for my dads birthday and he previously had an old slow windows desktop hence the upgrade. The only problem I'm running into with the switch is opening some windows file I transported via USB. My dad would use microsoft excel and word to make important spreadsheets and files for his business. I'm trying to open them up somehow so he can view them on his new IMac but a message saying "no application available to open up" keeps appearing. So is there anyway I can open these windows documents up on my dads new iMac? If so how? I Appreciate any help or response thank you.
