// NSTextField has alignmentRectInsets = {.left=.right=3, .top=.bottom=0}, so
// when autolayout aligns NSTextField to its container's side margin (e.g. to x=0),
// the actual x position is -3, and the label gets clipped.
//
// ATUnclippedTextField compensates for that by overriding drawRect to extend
// the clipping rect by alignmentRectInsets.

How to Symbolize OSX Crash Logs

Unfortunately, xcode does not yet have support for importing OSX crash logs and symbolizing them. Therefore, you must use the command line and a little bit of manual work.

1. Find your dSYM file.
   1. Assuming you are using xcode's archive functionality, open the Organizer window from the Window menu.
   2. Click the Archives tab.
   3. Right click on the appropriate build and select Show in Finder.
   4. When Finder opens, right click on the selected archive and select Show Package Contents.
   5. Navigate to the dSYM directory and copy the appropriate dSYM file to a temporary directory.
2. Then navigate to Products, then Applications, and copy the app file to the same temporary directory.

Exporting (iCloud) Keychain and Safari credentials to a CSV file

Update (October 2021)

Exporting password + one-time code data from iCloud Keychain is now officially supported in macOS Monterey and Safari 15 (for Monterey, Big Sur, and Catalina). You can access it in the Password Manager’s “gear” icon (System Preferences > Passwords on Monterey, and Safari > Passwords everywhere else), or via the File > Export > Passwords... menu item). You shouldn't need to hack up your own exporter anymore.

Original, Obsolete Content (2014)

After my dad died, I wanted to be able to have access any of his online accounts going forward. My dad was a Safari user and used iCloud Keychain to sync his credentials across his devices. I don’t want to have to keep an OS X user account around just to access his accounts, so I wanted to export his credentials to a portable file.
