Researchers Dhiru Kholia and Przemyslaw Wegrzyn have discovered a method to reverse-engineer Dropbox, which may open the door for open-source clients, but also gives attackers a way to intercept encrypted content and bypass the file sharing service’s two-factor authentication. The discovery has broader implications for the Internet, as the same methods could be used against any proprietary app built using the Python language. A Dropbox spokesperson said that while they “appreciate the contributions of these researchers,” the discovery “does not present a vulnerability in the Dropbox client.” Dropbox argues that the exploit will not work unless the user’s computer is already compromised. follow link
Fixing Save as Adobe PDF Crashes
There have been many reported instances of the "Save as Adobe PDF" workflow crashing regardless of application, but precious few workarounds or resolutions. In troubleshooting, I discovered that there were three instances of the "Save as Adobe PDF.action" in three different locations: /Library/Automator; ~/Library/Automator; and /System/Library/Automator. By eliminating all except the version in /System/Library/Automator, the workflow started behaving, and I was able to cut PDFs directly from the Print dialog.
