Unable to Partition a new Macbook Pro As a brand new Mac user this might be my naivety or an issue with the OS.  I bought a new Macbook Pro today and wish to partition the disk to allow Windows to be installed and Linux too.  I was advised in the shop that this was straightforward using the Disk Utility tool.  However, when I attempt to create a second partition, I am presented with the following:

Partition failed with the error: This Core Storage operation is not allowed on a sparse logical volume group.


Having scanned around for similar articles I see that this is a common problem when people have installed Yosemite on a SECONDARY partition.  In other words they already had a partition.

I also found that disk encryption may be an issue.  So I checked File Vault under Security and Privacy.  This tells me that File Vault is turned on for the disk Macintosh HD.  So I try to correct this but I'm advised that Encryption paused and that I should Connect power adapter to resume encryption.  And of course when I connect the power adapter this has no effect.

After 20 years on Windows I thought this would be different: a perfect operating system was my dream.  Please advise how to proceed, I'm stumped!

PS here's a dump of the diskutil output:

I had the same issue. It worked once the encryption was complete. My encryption resumed as soon as I plugged in my computer.
