wacom板子在MACBOOK里用PS画画的时候，老是画着快捷键就都不能用

原因1：

是photoshop CS6本身和wacom板子兼容的问题，安装一个补丁就好了！

如何安装补丁在这里（放心，这个是adobe官网的帮助链接）：

下载那个zip文件，解压出来的文件放到photoshop安装目录下的plug-ins目录里，再启动ps就已经完美解决问题了。

不过需要注意的是，补丁只能是针对cs6和CC2013的版本。

原因2：

插到MacBook上的鼠标(特别是无线鼠标)干扰了Wacom板子，无线鼠标关掉后再用Wacom就不会出现上述问题。（亲身经历！）

Get file 

WhiteWindowWorkaround.plugin1_0_6.zip

Unzip the file【我下载后貌似没有解压，直接拷贝到Plug-ins目录下重启就好了】, WhiteWindowWorkaround.plugin, and move it to //Applications/Adobe Photoshop [Version]/Plug-ins/

You can verify the plug-in is installed by launching Photoshop and choosing Help > System Info.

Scroll to the bottom of the text in the dialog box and look for the plug-in name.
