Recently (over a month ago) I had to swap out the hard drive on my iMac. I thought the new system would automatically sync with dropbox. Now my iPhone, pad and laptop all show updates as of the old system swap out date, which is what the online version of Dropbox also shows. I do 99% of my work on my desktop iMac, so I need the iMac info to be the online stored information. When I realized this and tried to sync the desktop, Dropbox tries to download the online version of info to the iMac, when I want the iMac information to be uploaded to Dropbox online to be the stored information for all devices. I hope that is not too confusing. Thank you.
