I need to clear / flush the DNS cache

[forteman]

I am working on a website but moved hosting companies. The site is live however I can't view it on my iMac via Virgin Media but can view it on my mobile through 4G.

I have cleared the cache on the iMac and restarted but the problem remains. I need to work on the website and can't wait until tomorrow. 

So how do I clear / flush the Virgin Media DNS cache? (please explain simply....I am not a techie wizard like you). 

Many thanks, Chris

Sorry I misread it as you did so on Apple and wanted to know how to on PC.

CCleaner has a section for doing this on PC (may be same on MAC).
