3. Click the [Uninstall] button.
4. When prompted, enter your K9 administrator password and click [OK].

6. When the uninstall process is complete, you will receive a message saying K9 has been successfully uninstalled.

DO NOT ATTEMPT TO UNINSTALL K9 WITHOUT A PASSWORD. By design, K9 will block all web access should anyone attempt to uninstall without using a password. Attempts to modify K9 at the system level will have the same effect.

Hi,

Uninstall Chrome completely and do a fresh install.

Unfortunately, the most likely reason is that your macbook air lacks the graphics processing power to handle the cinematics especially if you have the 1st generation mac air. Unlike the macbook pros, macbook airs do not have a dedicated discrete graphics processing unit (GPU) and instead use integrated graphics built onto the motherboard of your computer (not very powerful but good enough for everyday things except gaming). I know this because I've had similar issues with my friend mac air and my own laptop--sometimes things will work and other times they just don't. If you want to see a list of game that have been reported to have issues running on the air, check here.

When troubleshooting a Macbook Air, there is a checklist from Apple Support you need to try.
You are welcome to do so after first trying these steps first.

• Check the Magsafe power adapter, to make sure it is free of debris and is seated properly.

• If with decent charge, try to start the Macbook Air, with only the battery.

If you get power from either one of these issue resolved- otherwise follow the steps provide more in detail from Apple listed in the link below.

Such power issues with Macbook Airs as well as Macbook 13" and Macbook Pro 13" are about the same and there are no workarounds, so make sure to follow those procedures completely for a full assessment of your Macbook Air's functionality.

Hope this helps!

uninstall the sound driver and restart the system.
install the sound driver once again.
one more restart will solve your problem
