Hello everyone.


I have a 2010 Mac Pro 2.8 Quad. After updating to OS X 10.8.2 yesterday I noticed something weird upon boot when holding down "option"




I have 3 Bootable Drives on the machine:


1st. OS X mountain lion - Primary

2nd. OS X snow leopard - for some old ppc apps running through rosetta

3rd. Windows 7 - games




I'm aware that when I hold option to boot into a specific partition my 1st. OS X mountain lion has a "recovery" partition as well giving me 4 bootable partitions all together.


after the 10.8.2 update I'm getting a 5th partition labeled "Boot OS X" If I go ahead and click that it actually boots form my 1st. OS X mountain lion partition.




Now this has not in any way caused my machine to misbehave. I was wondering if anyone else had this happen to their computer after the update.


I don't understand the purpose of this redundancy. so my 1st. OS X mountain lion - Primary partition is showing up in the boot options twice.




on the other hand my macbook air did not do this after the update.




Please let me know. I would really appreciate it.
