Okay, I have iCloud on my main iMac, macbook, iPad, and iPhone. I have a file uploaded to the iMac, listing the ungodly number of dads my husband and I own, trying to prevent duplication. Anyway, yesterday I opened it on my iPhone, made changes, closed it, and it was updated through iCloud on all devices. Fine and dandy. Then I open the file today on the iMac, have to download it since there were changes (from the iPhone), make changes--and here's the stupid question: How do I update the file through iCloud. I'm told to upload it, but (I know this sounds stupid) how do I do that? I have the downloaded and altered file open. How do I upload this open file to iCloud? If I try to save it, the only option is "save version"? Help with what I know is a simple question?
