I'm pretty new to the whole Mac OSX way of computing, so this is probably a stupid error to make... HOWEVER... I recently installed Audacity on my MacBook, which worked fine, but when I went to export my track to MP3 form, it told me I needed to install an encoder called LAME. So I went to the Audacity webpage and downloaded the LAME application. The problem is that now I cannot install the application as every icon I click on in the downloaded file, I get the message "There is no application specified to open this type of file" or something along those lines. Is there another application I need to install in order to complete the installation of LAME or is there another programme I can use that is guaranteed to work? Any advice would be appreciated!
