iWork iCloud sync not working on just iMac
I have been using iCloud document and data syncing very happily across iPad, iPhone5, MacBook Pro and iMac for months.
Then I needed to move a number of iWork documents (Pages, Numbers and Keynote) from iCloud to a local server. I did this by copying them to my server, then deleting the originals from iCloud, using my MacBook Pro (10.8.4).
I now have a smaller number of Pages, Numbers and Keynote documents created/modified on various devices that remain on iCloud - and which are accessible from all of them.....except from my desktop iMac (10.8.4).
In (for example) Pages, this continues to display a list of all the documents that were there, as well as all of those that remain - but with a blank (and non-moving) progress bar and will allow me to view none of them.
I have read various threads, and done the obvious turn off/on documents and data syncing in iCloud preferences to no effect. I have only one account syncing documents and data.
Can anyone offer any clues?!
Many thanks.
