Vysor black screen on mac mini os with inter hd 3000 graphic card

When I tried to install vysor chrome extension, I was told that vysor is not supported by this computer.

I then download vysor mac version. It worked well, except the mirror screen on the mac was black. I could still control from mac and take screenshots.

I checked the chrome extension again and noticed that webgl is required for vysor. I then tested webgl on both safari and chrome.

Both of them were not working.

I tried to enable webGL from safari's develop menu, but "enable webGL" is not there.

I also enabled webgl from chrome's settings, but it didn't help.

I thought my graphics card may not support webGL.

Then I found a page saying that Intel HD 3000 is blacklist by chrome on mac. 

Then I used the following command to launch chrome.
