Thanks for the suggestion.Sue commented
I believe a better term would be "mirror" versus sync. I have a Macbook Pro with a limited hard drive, and I would be like to be able to mirror my OneDrive account in Finder. I don't want to sync, because I don't want copies of the files on both systems. I haven't got the space. DropBox does this with no issues, but my storage there is limited as well. It is looking like Google is my only option if this is not a priority for Microsoft.
