Paintbrush is an equivalent of Paint for a Macbook. It is available as free download software on MAC’s service website. The software allows 3D painting, and takes less than 2MB of space before installation. Paintbrush 2 has released a similar version of its predecessor, but is claimed to be better engineered, faster and simpler. Preference settings for using the software allow Windows users to grasp the software operations easily. Although Paintbrush is great for MAC OS X and the Leopard series, Paintbrush is expected to be revamped very soon.
