What if the iCloud icon does not show up in your system preferences?
I am unable to manage the storage of iCloud on my iMac due to not being able to find the iCloud icon in System Preferences on the desktop. Why is this?
iMac, Mac OS X (10.6.8)
Systems before OS X Lion 10.7.2 do not include iCloud features. Buy an upgrade to Lion (or wait for Mountain Lion to be released later this month and buy that).
