This become tiring so I started looking for the best app that watches a folder for changes and updates the browser automatically.
The Best solution out there currently is CodeKit, which not only solves my basic issue but also does a lot more. It’s main purpose is to support preprocessing. Very handy when you start using more advanced features like sass, less or jade.
The only draw back to code kit is that it requires Mac Lion OS. This is a problem since my work computer has snow leopard. If you are in this situation then there is a second recommendation
Live reload does pretty much everything Code Kit does but runs on snow leopard. From reading both features, CodeKit has better performance since it utilizes the new features only found in Lion.
CodeKit will run you $20 while Live reload cost $10.
