I have the latest generation Macbook Pro running Yosemite, I bought this computer used I don't know if the last person attempted to install linux or what the story is but I believe my partition map is a little weird.
Here it is First off I expected to have only a disk0 I don't know what the disk1 is. I expected the drive name "Apple_CoreStorage" to be called "Apple_HFS Macintosh HD" like it is on disk1 both of these disks also say that they are 320GB in size although my HD is only 500GB.
There are also 2 recovery drives but when I boot into recovery mode it says that it is loading it from the internet. I don't know if that is how it works or if it is not recognizing either of these.
My Final problem is with disk0s5 There are 180GB that I cannot access it is partitioned as disk0s5 I can remove the partition but then it is just mapped as free space. I try to increase the size of my "Macintosh HD" after removing the 180GB partition but I am not able to.
I feel like both of these problems are deeply intertwined, maybe my map is fine I am unsure but it doesn't look right to me. Any ideas would be appreciated thank you.
