This is just a workaround that doesn't fix the issue and the OS update surely doesn't fix the issue. I followed this procedure to do the OS update a couple weeks ago and now I have another update that continually gives me the "Gateway Timeout" error again. So ... Apple, are you going to fix the issue, tell us step by step how to fix the issue or tell us another work around? This particular update is for the "Epson Software Update 3.3" and while it's not important, it's just irritating that I've had this issues for months and I still have to waste my time figuring out how to fix Apple's annoyances.
