Click the Check Now button, and DropDMG will tell you whether a newer version is available for download. By default, DropDMG will automatically check for new versions each time it is launched and once per day. You can disable this feature by unchecking the checkbox.
If a new version is available, DropDMG will tell you what’s new in that version. Click Download to have DropDMG download the .dmg file for the new version to your Internet downloads folder. Click Download & Install to have it download the .dmg and then update the installed DropDMG application to the new version.
To check for a new version, DropDMG contacts a Web server at dreamhost.com. DropDMG transmits the following information to the server: the name of the product (DropDMG) and its version, the version of Mac OS X, whether DropDMG is registered, and the name of the current language. This information is used to guide future development. No personal information is transmitted.
