I'm having performance issues with Minecraft on my Hackintosh (A computer with Mac OS that is not manufactured by Apple).
Now, I only get around 30-40fps when all nearby chunks are loaded and maybe 20fps when the world is generating.
In a Microsoft Windows 8.1 environment on the same machine I would, at least, get 5x that.
Additionally, I have tried having Minecraft in a small window, a large window, in a separate Space and in fullscreen mode, but none of which helps performance-wise.
Please no:
- use Windows
- Hackintosh sucks
The file linked for download below is a system report file of my computer.

Side note: Running the game on a lower setting than max is out of the question.
I have a MacPro that used to run 10.6.8 for the last year, playing minecraft fine. I loaded 10.9 Mavericks on it finally (using the boot.efi method) and minecraft performance dropped. Sometimes as low as 5-8fps. (4 core, 8800gt)
It looks like java is now bound to one CPU only, it will only go to 100% (with system then at 25%). In 10.6 minecraft would use all cores, and cpu usage be 300-400%. I have tested java6 and 7, no difference there.
As a temporary fix, if I load minecraft module "optifine", the fps is generally around 25, so it is again playable. But hopefully someone will figure out how to unlock java or whatever the real problem is.
Ok so it wasn't really fixed. Minecraft would start around 30fps, but always drop to 10 or so. With OptiFine it is about 40fps dropping to 16fps.
Tried many things, java7, java8, memory, kernel compression off, new nvidia drivers etc. All other OGL games are fast.
Before:
MacPro1,1, 8800GT, 10.9.2
The I threw in a Radeon 6770 that I had lying around, no booting gfx, but what a difference. With OptiFine I stay around ~100 fps. Without about 60fps. Normal about 60fps, and staying around 50fps.
So possibly it was something related to the 8800GT.
I , and the kids, can play minecraft again though.

Retired StaffJava is not known for multi threading. It has always only utilized one core.
sudo nvram boot-args="vm_compressor=1"
this appears to bring fps into the playable range again.
I think that is fixed for me.
