Fixing TweetDeck and Adobe Air Apps in OS X

Update (7/21/09): TweetDeck finally speaks up about this issue, offers the same exact advice as below: http://tweetdecksupport.posterous.com/fixing-the-blank-tweetdeck-problem?

Yesterday I launched TweetDeck to get my Twitter fix and was surprised to see TweetDeck stuck with a blank empty screen:

Searching around I discovered that there are two places where TweetDeck stores it’s data:

Preferences Folder

This contains preferences like your columns, layout, etc.
To find this folder go to your Home directory -> Library folder -> Preferences folder then find the folder that starts with TweetDeck.
The actual path on my machine is:
~/Library/Preferences/TweetDeckFast.F9107117265DB7542C1A806C8DB837742CE14C21.1

Adobe AIR Encrypted Local Store (ELS)

This contains your login info to Twitter
To find this folder go to your Home directory -> Library folder -> Application Support folder -> Adobe folder -> AIR folder -> ELS folder then find the folder that starts with TweetDeck
The actual path on my machine is:
~/Library/Application Support/Adobe/AIR/ELS/TweetDeckFast.F9107117265DB7542C1A806C8DB837742CE14C21.1

I tried moving/deleting the Preferences folder, but that did nothing. I ended up deleting the Adobe AIR ELS folder and leaving the Preferences folder as is. TweetDeck asked me for my Twitter credentials again, but then everything was back to normal, including all of my preferences.

If you are on Windows you can find these folders here (courtesy Christopher Grant):

C:\Documents and Settings\[user]\Application Data\TweetDeckFast.[guid]
C:\Documents and Settings\[guid]\Application Data\Adobe\AIR\ELS\TweetDeckFast.[guid]

Copy printers between machines in Leopard

To copy the list of installed printers from one machine to another, copy the following files:

/etc/cups/printers.conf
/etc/cups/printers.conf.O
/etc/cups/ppd/*
~/Library/Printers/*
~/Library/Preferences/com.apple.print*

Make sure the files in /etc/cups retain the proper owner and group (root:_lp) and permissions (‘u=rw,go=’for the conf files and ‘u=rw,go=r’for the ppd files).

You’ll also have to re-install any printer drivers that you installed on the old machine.

Restart after you’re done and System Preferences -> Print & Fax should now show your printer list.

Leopard Migration Assistant Bug

After installing Leopard and restarting, Migration Assistant offers to transfer your data:

If I chose “from another volume on this Mac” (connected via USB) or “from another Mac” (connected via Firewire disk mode), I’d immediately get one of these errors:

“Mac OS X was not found on the volume you selected.”
“There are no version of Mac OS X on your old Mac.”
“You can only transfer information from a Mac that has OS X installed.”

The error comes right away, before I actually selected anything. The drive booted without any problems either.

So here is the very non-intuitve fix in case any one else runs into the same problem:

When the error comes up, just let it sit there for a while (a good 10 minutes in my case).
You’ll then start to notice that the information from your drive/machine starts showing up (Account info, size of the Applications folder, etc)
After all the information is populated, click Cancel in the dialog box which will take you back to the previous screen.
Select “from another volume on this Mac” or “from another Mac” again and this time there will be no error.
