Almost all the items on your Mac machine (including folders, movies, music, pictures, documents, applications, pdfs, calendars, address books, emails, archives, disk image files, etc.) are supported.
Step 3 : Customize DMG window size, layout & background
On the right toolbar, there are 3 tabs: "Window Options", "DMG Info" and "Grid". “Windows Options” tab is the default and it allows you to customize the appearance of the window of DMG file when opened.
Window Position & Size:
Use the “Left” and “Top” spinners to adjust the space between the upper-left corner of the screen and the upper-left corner of the DMG window; use the “Left” and “Top” spinners to specify the size of the DMG window as you wish.
Window Position & Size:
Either select the “Color” radio button to pick a solid color or the “Picture” one to drag and drop a picture as the background of DMG widow.
To make the window background fit the image, click “Fit Image”.
Since lots of pretty background templates are provided in this Mac DMG creator, you can also simply pick one from them: click the “Template” icon on the top toolbar, you’ll enter the “Template” interface, then choose the template you like as the background image.
Of course, you can also import your own background images as templates for convenient future use by clicking the “Add Template” button. Once added, you can choose it from the “My Template” group easily.
In addition, click the “Background” icon on the top toolbar to enter the background panel, and in the panel, you are allowed to add pictures and text instructions to the background image. When all the things are finished, click “OK” to apply the texts and images to the background image. If you want to save it as a background template, choose “OK & Add Template”.
Determine whether to “Show Sidebar”, “Show Status Bar”, “Show Toolbar”, “Show Icon Preview” or “Show Item Info” on the window when the DMG disk image file is opened. Besides, adjust value of the “Text Size”, “Label Position” and “Icon Size” as the default “View Options” of the packed items when the DMG window is opened.
Step 4: Specify position of imported items in DMG window
Highlight and drag the items imported to the proper positions to fit the specified background template. To accurately locate the items, switch to the “Grid” Tab. Under the tab, options of Grid and Scale will help you put the files at the right places easily.
Quickly add symbolic links to “Applications”, “Documents”, “Desktop”, “Downloads”, “Movies”, “Music” and “Pictures”.
Step 5: Set DMG volume options
Switch to the “Volume Options” tab and specify the volume name, volume format and more of the mounted DMG file.
Specify the volume name and icon that you want to display as the DMG file is mounted.
Set the file system of the DMG disk image, and “Mac OS Extended” and “Mac OS Extended (Journaled)” are optional. Journaling for the Mac OS Extended (HFS Plus) file system enhances computer availability and fault resilience, which is especially noteworthy for servers. To learn more about “Mac OS Extended (Journaled)”, please visit http://support.apple.com/kb/HT2355.
Set the package and compression method that you want to use for the DMG file.
Manually type in the size of the disk image to shrink it so that its HFS/HFS+ partition can be converted to CD-R/DVD-R format and still be burned.
Specify the encryption method and input the key to protect DMG file.
Enable or disable download post-processing (IDME). When enabled, a browser (or Disk Copy 10.2.3+) will "unpack" the contents: the image's visible contents will be copied into the directory containing the image and the image will be put into the trash with IDME disabled.
When the disk image DMG file is double-clicked, the resulting volume will be automatically opened in the Finder.
Import text files to set the multi-lingual software license agreement which will appear before the DMG file is mounted. If no localized language is found, the top one on the list will display. It’s especially useful for Mac app developers.
Step 6: Save DMG creation settings for later use (Optional)
Click “File” > “Save as” of the menu bar to save all the operations that you have done to the current DMG-making project as a *.dmgdoc file. To resume the project, just open the DMG maker, go “File” > “Open” to import the .dmgdoc file, then all the things will come back just as the time before the save.
Step 7: Create DMG file or burn data to CD/DVD
Click the “Build” icon to start making DMG image file or hit “Burn” to burn the disk image directly to CD/DVD.
