March 27th I had this problem that whenever I submitted an app to the app store with the App Loader or Xcode, that would pass verification mind you, I got an error: "com.apple.transporter.util.StreamUtil.readBytes(Ljava/io/InputStream;)[B" I wrote Apple to tell them about it, but I got an error due to a disk being full, so I figured nobody's perfect, it's probably a disk-full error, and tried the next day. The 28th, no luck either. Wrote them a mail. Didn't hear from them by the 31st, so wrote another mail. But by now, results had began to come up on my radar via Google, so I thought I'd share what I found.

With Xcode 4 it seems many people are having this problem. The advice I found first was to downgrade to Xcode 3.x or Application Loader 1.3, but by this time Xcode 4.0.1 was out, and for some reason I'd missed installing it on my dev box.

After installing XCode 4.0.1, this problem was solved and an updated version of Well Tempered is now awaiting approval.

A few times I've experienced that OS X' Mail has just stopped downloading new messages via POP from GMail. I've been all around Google's mail system to try to figure out why Mail and GMail all the sudden won't co-operate anymore. Not having any luck there I began exploring and found a solution:

For the sake of example, my account will be called username@gmail.com

Go to ~/Library/Mail/POP-username@gmail.com@pop.gmail.com

In that folder there is a file called MessageUidsAlreadyDownloaded2. It's an XML file that contains stamps of when what mail downloaded from GMail. Mine was about 45k large. I quit mail, moved this file away (just in case) and started Mail again. And voila! Mail is downloading mail from GMail via POP3S again. And it picked right up on where it left of.
