Hey,
Since updating to yosemite whenever I open Magic kernel task jumps up to 200-290%, is this normal?

Re: Kernel_task
No, not normal
. On my Macs the kernel_task only uses a few percent even when Magic is open.
I'm not sure what could be causing it but have you considered upgrading your OS? Honestly Yosemite was not a good release; there were several problems.
