After updating my system to Mac OS X 10.7.2 I was able to activate all features of iCloud, except for Find My Mac that stays greyed. It says "Recovery partition required".
I have a Macbook Pro, Middle 2009 model, and it was updated from Leopard to Snow Leopard to Lion.
Searching Apple's support website I could find articles on how to create the Recovery HD in an external drive, but I can't find how to create the partition in the internal drive. I have enough free space to repartition, and I have already created a 1 GB partition at the end of the free space (Apple recommends 1GB when creating the partition in an external drive).
I understand the Recovery HD is necessary for Filevault 2 too, so there must be a way of creating it after installation, but I can't find how. Anyone knows how to do that?
diskutil list
from Terminal. Does it list a Reccery HD on your main partition (should clock in at 650 MB). If not, the only way to recreate it is to reinstall Lion (which actually just replaces all system files, so you won't lose anything in your profile). Also there's an update to the Recovery Partition that was released alongside 10.7.2. Make sure you have that installed to.
