[EDIT: All is well now... Carry on.]
Just received an email from the Apple Developer Connection. The seed of Snow Leopard 10A190 is apparently posted to the Apple Developer Center.
However, mere paid-an-in-good-standing devs like me are apparently not allowed access.
You do not have access privileges to download the software you are requesting. If you believe you have received this message in error, you should confirm your access privileges directly with your Apple contact or view the downloads that are currently available to you.
I don’t get Apple sometimes, I really don’t. I LOVE their hardware and software. Top to bottom. I love their stores. When I travel I try to go out of my way to tag an Apple Store. But, when it comes to the ADC… it’s been a love/hate relationship now for six years.
They send me this email with no hint of exclusivity for this particualr disc image. Looks like every other click-to-download link they’ve ever issued.
