I have my doubts that this is a Lion issue, but I am still hoping other users can confirm my issue or help me fix it. Basically steam for OS X will not get passed the "connecting to: *user*" screen. It simply hangs. Oddly enough though it worked fine yesterday, and I even had steam open earlier today. I could not get any games open, but I had the program open and had attempted to check the validity of my game cache's. The validity check made it to 100% then hung. I have not been able to get steam open since. I have attempted to create a new Clientregistry.blob I have re downloaded and installed steam onto my Mac I have turned little snitch off completely I have googled this issue extensively. So now I am asking anyone who has steam on their mac running Lion to see if it is working for them. At this point I am hoping it is a temporary server issue on Valve's end.
