Hi there

Really depends,you can make from yours laptop Hackintosh Macbook,done that with my brother and done that with my PC...Its really easy and really you are need to do bit of research as with everything

Regarding Macbook or Mac,been tried and reverted back to Windows machine,which has running OSX although...

Regarding speeds and regarding comparing the Mac or Windows machine,Apple always claims their own and MS claiming their own,truth is somewhere in middle,some programs you can run on OSX and some programs you can't run on Windows machine,I'm still on Windows 7 and I'm not looking to upgrade anytime soon,because is not worth it for me..

If you game then OSX is not for you,most of games which are ported on OSX run lot slower than on Windows this is main thing for many people,there is still not resolved issue with OpenCL if you render with Reality,CUDA drivers are how to say mildly poor,some apps like Final Cut have poor performance with NVIDIA cards if you are want to use that

Regarding Poser 2014 this again depends,last time when I tried to install on friend MacPro(trash can model) we are run to issues with Libraries,not sure if this sorted and plus we are run to issues with runtimes which has been located not on main SSD/HDD

I would say,try before you buy,if yours friend have Macbook then please try if this is for you or not,but I wouldn't never buy Mac pro or Macbook,when I can build comparable or faster machine for lot less,but that's me

Hope this helps and good luck there

Thanks,Jura
