How do you transfer from local host to server on Mac?

Hi,

I hope someone out there will be kind enough to help me out here. What precious strands of hair I have left are quickly turning gray, due to the stress of wordpress on a bloddy mac.

I managed to download the thing and have it running locally on my mac. I even managed to import my old posts from my crappy iWeb blog.

So then I wanted to publish this to the net. Not easy on a mac. I changed the address/url or whatever it is to my website’s name. I then got lost pissing around with php my admin and stuff.

So now, when I try to access my website on my local host, it’s not there.

How do I get it back?
