I have some trouble with my partitions on my Macbook Pro. I created 2 partitions. One named "Yo" where I have installed Yosemite release. Another one named "Save" where I put all the stuffs I need to keep secure for work.
I want to create a 3rd one to re-install Mavericks just because one of my app is not working on Yosemite.
The trouble is that I can't do it through the Disk Utility GUI because everything is disabled. I saw a post here where they talked about using diskutil command in the terminal. I tried to follow it but I have something weird when I try to list all my disk. Here is the output:
$ diskutil list /dev/disk0 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *251.0 GB disk0 1: EFI EFI 209.7 MB disk0s1 2: Apple_CoreStorage 224.9 GB disk0s2 3: Apple_Boot Recovery HD 650.0 MB disk0s3 4: Apple_HFS Save 24.5 GB disk0s4 5: Apple_Boot Recovery HD 650.0 MB disk0s5 /dev/disk1 #: TYPE NAME SIZE IDENTIFIER 0: Apple_HFS Yo *223.3 GB disk1 Logical Volume on disk0s2 C5EE25C4-6BC6-4E56-961A-F43335118355 Unencrypted
What I want to achieve is having these 3 partitions:
- "Yo" -> 180GB
- "Mavericks" -> 45GB
- "Save" -> 25GB
Is that achievable without having to reinstall Yosemite and if so how can I succeed to do that?
