Question / Help CPU Usage I Macbook Pro

[RaMba]

Hello I got a problem streaming with OBS.

My Mac:
i5 - 3210M @ 2.50 GHz
16 GB RAM
500GB SSD

My stream was alright 6 months ago with an HDD and now I wanted to start streaming again but my OBS always goes up to a CPU usage of 60-70% and my stream is unwatchable.
