My new MBP has arrived today and first thing looked to install Steam so I could run some games like TF2 / L4D from my account. I've tried logging on many times and I keep getting Login to steam failed. Either the specified account does not exist or the password was wrong. Please check your username and password and try again. I've tried again many times. I've booted my Win7 laptop where I originally had Steam and can logon without a single problem I've reset my password and tried again on the macbook I have tried every username and password combination possible I'm scratching my brains out here - I've got a large steam collection and will not re-purchase this again. Can anyone advise how this can be sorted?
Just to clarify - my account is not hijacked, I can access it fine from my windows laptop running next to me.

Once you get used to the somewhat clunky GUI, it's very good at tracking the store sale of the day as well as the big sales, and your library. I don't use it for any other deeper functions or communicating with friends or anything else, so I don't know whether all the additional features work. I did try remotely installing a game after purchase, and I know for a fact my pc was turned on and had Steam running.but the game install request simply did not queue up in the Downloads area on the PC. That's first world software problem though. The store purchases work fine and quickly, which is the important part. My only suggestion I have is to please please please add 'swipe back' browsing gestures.
It's annoying that the back button must still be used while browsing the store all this time later as iPhone processing power effectively doubles each year. We don't need pinch turn or any other fancy gestures which no one uses.we need reliable 'swipe back' though. Mbrogz3000, Great app for checking the Steam store.
