What's the best free drawing software for Mac?

You could try using Gimp for Mac. I used to use it and it’s a great free alternative to Photoshop.

Gimp is good but it can be complicated for new users. PaintBrush is great for simple stuff. I like having the two buttons for painting but it does the job.

http://www.pixelmator.com/ is very good.

But it isn’t free. It is cheap.

@johnpowell Oh yes it is good. I used to use it until I got Photoshop. Had no use for it then.

if your looking for vector

then inkscape is good.

Here is a really good site. It gives you opensource or free alternatives for all the main commercial software packages based on categories and rates them.

I am running OS X version 10.4.11 and am looking for a simple drawing/illustration application, I used to work with the earlier version of Canvas and it fit my needs easily. Now it seems when all I want is Volkswagen the only things available are Ferraris.
Any suggestions?

@RTSlater – Welcome to Fluther!

Paintbrush http://paintbrush.en.softonic.com/mac is very simple. You should also go to http://www.osalt.com/ and see what they have there. I have not used Canvas so I am not sure what level it is. But that site has a mess of free alternatives. Maybe you can find the right match for you.

I use sketchbook pro with a graphics tablet, pretty simple but effective. It’s not free though.
Also, check out ArtRage . I haven’t tried it yet, but it looks promising.
