Safari Problems Downloading .DMG Files

A number of users are reporting that Safari 4 is no longer downloading .dmg files. Here’s how I fixed the problem when it started happening to me.

A while back I started having problems with Safari 4 being able to download files. Normally when one clicks on a .dmg or .zip file, Safari downloads it.

Recently, it stopped working, either doing absolutely nothing or trying to load the file into the browser itself for display. It was as if the MIME type wasn’t properly being handled.

Here’s how I fixed it.

It appears that Speed Download‘s broswer plugin is to blame. While it works amazingly well with Safari 3, it doesn’t seem to work quite right with Safari 4.0.3.

  1. Quit completely out of Safari.
  2. Go to /Library/Internet Plug-Ins directory and locate the file SpeedDownload Browser Plugin.plugin and move it out of that folder.
  3. Restart Safari.
