I’m all about efficiency — especially when it comes to downloading my torrents. I’ve been gradually getting more and more annoyed that every time I download a .torrent file, I have to double click it (in the Downloads window) to have it open in Transmission.
Solution: Download this zip file which contains a revised version of com.apple.DownloadAssessment.plist. This is the file that tells Safari what files are safe to open after downloading – it’s been revised to include .torrent files as “safe.”
After unzipping, just move the file to YourUserName/Library/Preferences; replace the file if it already exists.
P.S. Thanks to Manuel Studer for this tip!
