Hey guys,
Whenever I open Blender it always closes and says The application Blender.... has unexpectedly closed"
I've tried re-downloading it, same thing happens.
any help?

It might be pc performance or it needs new blades.

Otherwise, check online via google or their helpline. :3

Or this?

Blender is avaliable cross platform, but utilizes OpenGL for drawing the entire interface. That means you best use a graphics card and drivers that conform to the OpenGL specifications.
Unfortunately there are a lot of cheap graphics cards on the market that only support a basic sub-set of the OpenGL specs. VIA and Intel cards are infamous for this.

Use unity. Lol
I've been having the same problem too, so I used unity.

iS Unity a 3d program?
If so, please link me.

The same as blender, but for me much better. https://store.unity3d.com/shop/

Get the free version, then you're all good to go.

wut.

Unity is a tool designed to make 3d/2d games. Blender is a tool designed to make 3d models.

edit: Oh yeah, op, it would be helpful to know your os and system specs.

Mac Osx 10.5.1
Thats my version.

Seeing this, it's your Graphics card being old, and have you updated your drivers?
