Blender sluggish on OSX11 and Intel GMA 950

Please forgive me if this post is common or the like, I have tried the FAQ at and done some searches with no fruit.
I have recently got a mac and Blender is running quite sluggishly, I don’t know if this is because of OSX11 or my graphics card (Intel GMA 950).
I was hoping that the duo-core business would speed me up no end, but it seems not to be the case at the moment.
Any input appreciated.
Oh yeah, and GIMP simply refuses to run even after optional installs have been applied, but I haven’t done much investigation into that problem as I’ve only just got internet running in my new house!
