As the title states what is it? After upgrade to 10.7.2 I show this file under a developer header in finder on my 2011 MBP. It does not appear on my 2010 iMac. Also, before the upgrade I was able to see the recovery partition in system information under serial-ata on my MBP. It never appeared on my iMac. Now it is gone. Any ideas on these two issues. I hope I explained the problems correctly. Any ideas.
