Delete iCloud bookmark only from a specific computer I have iCloud Safari bookmark syncing set up on two Macs and an iPhone. Is it possible to delete a bookmark (or set of bookmarks) from one machine only, so that they continue to exist on the other two devices?
As any changes performed to an iCloud-Sync service will  be pushed to all other iCloud-Sync devices, your only option would be to unsync the desired device form iCloud's Safari and then delete the bookmarks. 

Bear in mind that once you re-enable the Safari's Sync, all of its data will be merged together.
