They are Apple\u2019s preferred format for distributing Mac software and the only archive format whose contents you can directly access in the Mac Finder\u2014no extraction or third-party software required.<\/p>\n\n<p>Deliver your Mac app on a <tt>.dmg<\/tt> file with a <a href=\"https:\/\/c-command.com\/dropdmg\/help\/licenses\">software license agreement<\/a>, a <a href=\"https:\/\/c-command.com\/dropdmg\/help\/custom-volume-icon\">custom volume icon<\/a>, and a precise <a href=\"https:\/\/c-command.com\/dropdmg\/help\/layouts\">icon layout<\/a> atop a Retina-optimized background picture. Customers can install simply by dragging and dropping the app onto the convenient <tt>Applications<\/tt> folder link. <a href=\"https:\/\/c-command.com\/dropdmg\/help\/signing\">Code-sign<\/a> your <tt>.dmg<\/tt> so that macOS knows it can be trusted after download.<\/p>\n\n<p>This is a free update for owners of <a href=\"https:\/\/c-command.com\/blog\/2010\/06\/29\/dropdmg-3-0\/\">DropDMG 3.0<\/a> that includes the following enhancements:<\/p>\n\n<ul>\n\t<li><img decoding=\"async\" loading=\"lazy\" align=\"right\" src=\"https:\/\/c-command.com\/dropdmg\/images\/3.7\/dropdmg-icon-dark@2x.png\" height=\"128\" width=\"128\" alt=\"DropDMG Icon Dark\" \/>Updated DropDMG\u2019s application icon for macOS Tahoe 26 and the new Liquid Glass design language. It no longer appears in \u201csquircle jail\u201d and now adapts as you change the macOS appearance to use the Dark, Clear, and Tinted icon styles.<\/li>\n\t<li>Added images for each <a href=\"https:\/\/c-command.com\/dropdmg\/help\/the-dropdmg-menu\">menu<\/a> <a href=\"https:\/\/c-command.com\/dropdmg\/help\/the-file-menu\">item<\/a> when running on macOS Tahoe 26.<\/li>\n\t<li><a href=\"https:\/\/c-command.com\/dropdmg\/images\/3.7\/file-menu@2x.png\" title=\"File Menu\"><img decoding=\"async\" loading=\"lazy\" align=\"right\" width=\"161\" alt=\"File Menu\" src=\"https:\/\/c-command.com\/dropdmg\/images\/3.7\/file-menu-thumb%402x.png\" height=\"173\" \/><\/a>Added support for disk image files in the new Apple Sparse Image Format (ASIF):\n\t<ul>\n\t\t<li>Like the old <code>.sparseimage<\/code> format, the <code>.asif<\/code> format uses a single file and only consumes disk space based on the amount of data stored (rather than the disk image\u2019s logical capacity). It is much faster than either the <code>.sparseimage<\/code> or <code>.sparsebundle<\/code> format but requires macOS Tahoe 26 or later.<\/li>\n\t\t<li>Most of DropDMG\u2019s feature set works with ASIF disk images. You can:\n\t\t<ul>\n\t\t\t<li><a href=\"https:\/\/c-command.com\/dropdmg\/help\/new-blank-disk-image\">Create blank<\/a> ASIF disk images, using the APFS file system, and specify the capacity and volume name.<\/li>\n\t\t\t<li><a href=\"https:\/\/c-command.com\/dropdmg\/images\/3.7\/preferences-configurations@2x.png\" title=\"Settings: Configurations\"><img decoding=\"async\" loading=\"lazy\" align=\"right\" width=\"161\" alt=\"Settings: Configurations\" src=\"https:\/\/c-command.com\/dropdmg\/images\/3.7\/preferences-configurations-thumb%402x.png\" height=\"121\" \/><\/a><a href=\"https:\/\/c-command.com\/dropdmg\/help\/new-from-folder-file\">Create new<\/a> ASIF images from folders, packages, and individual files, with various options for specifying the <a href=\"https:\/\/c-command.com\/dropdmg\/help\/destination\">destination<\/a>, <a href=\"https:\/\/c-command.com\/dropdmg\/help\/names\">filename, and volume name<\/a>.<\/li>\n\t\t\t<li>Create new ASIF device images from attached disks.<\/li>\n\t\t\t<li><a href=\"https:\/\/c-command.com\/dropdmg\/images\/3.7\/preferences-layouts@2x.png\" title=\"Settings: Layouts\"><img decoding=\"async\" loading=\"lazy\" align=\"right\" width=\"161\" alt=\"Settings: Layouts\" src=\"https:\/\/c-command.com\/dropdmg\/images\/3.7\/preferences-layouts-thumb%402x.png\" height=\"120\" \/><\/a>Enable 256-bit AES <a href=\"https:\/\/c-command.com\/dropdmg\/help\/encryption\">encryption<\/a>. When creating a batch of encrypted ASIF images, you only have to enter the passphrase once.

This works even if both the source and destination images are encrypted, whether or not the passphrases are the same.<\/li>\n\t\t\t<li><a href=\"https:\/\/c-command.com\/dropdmg\/images\/3.7\/preferences-advanced@2x.png\" title=\"Settings: Advanced\"><img decoding=\"async\" loading=\"lazy\" align=\"right\" width=\"161\" alt=\"Settings: Advanced\" src=\"https:\/\/c-command.com\/dropdmg\/images\/3.7\/preferences-advanced-thumb%402x.png\" height=\"120\" \/><\/a>Convert archives (<code>.zip<\/code>, <code>.tar<\/code>, <code>.tar.bz2<\/code>, etc.) to the ASIF format.<\/li>\n\t\t\t<li>Convert ASIF disk images to other disk image (<code>.dmg<\/code> and <code>.sparsebundle<\/code>) or archive (<code>.zip<\/code>, <code>.tar<\/code>, <code>.tar.bz2<\/code>, etc.) formats.<\/li>\n\t\t\t<li>Convert an ASIF disk image to a new ASIF disk image (e.g. to change the encryption).<\/li>\n\t\t\t<li><a href=\"https:\/\/c-command.com\/dropdmg\/images\/3.7\/mount-image@2x.png\" title=\"Mount Disk Image\"><img decoding=\"async\" loading=\"lazy\" align=\"right\" width=\"161\" alt=\"Mount Disk Image\" src=\"https:\/\/c-command.com\/dropdmg\/images\/3.7\/mount-image-thumb%402x.png\" height=\"83\" \/><\/a><a href=\"https:\/\/c-command.com\/dropdmg\/help\/mount-image\">Mount Image\u2026<\/a> with an ASIF disk image. You can control whether or not the disk image is mounted with ownership information, whether changes are saved to a shadow file, and whether the disk image is mounted on the desktop or at an arbitrary location in the filesystem. If you bulk mount multiple encrypted disk images, you only have to enter the passphrase once if it\u2019s the same for all of them.<\/li>\n\t\t\t<li><a href=\"https:\/\/c-command.com\/dropdmg\/images\/3.7\/get-image-info@2x.png\" title=\"Get Image Info\"><img decoding=\"async\" loading=\"lazy\" align=\"right\" width=\"161\" alt=\"Get Image Info\" src=\"https:\/\/c-command.com\/dropdmg\/images\/3.7\/get-image-info-thumb%402x.png\" height=\"265\" \/><\/a>\n<a href=\"https:\/\/c-command.com\/dropdmg\/help\/change-image-passphrase\">Change Image Passphrase\u2026<\/a> for an ASIF disk image.<\/li>\n\t\t\t<li><a href=\"https:\/\/c-command.com\/dropdmg\/help\/compact-image\">Compact Image\u2026<\/a> with an ASIF disk image.<\/li>\n\t\t\t<li><a href=\"https:\/\/c-command.com\/dropdmg\/help\/get-image-info\">Get Image Info\u2026<\/a> for ASIF disk images.<\/li>\n\t\t\t<li>Use the <code>dropdmg<\/code> <a href=\"https:\/\/c-command.com\/dropdmg\/help\/command-line-tool\">command-line tool<\/a> or AppleScript to control or automate DropDMG.<\/li>\n\t\t<\/ul>\n\t\t<\/li>\n\t\t<li>Some features do not work with ASIF disk images, due to macOS\u2019s more limited support for them. You cannot:\n\t\t<ul>\n\t\t\t<li>Directly convert ASIF disk images to the <code>.sparseimage<\/code>, bzip2 <code>.dmg<\/code>, <code>.cdr<\/code>, or <code>.iso<\/code> formats or to a segmented <code>.dmg<\/code> format. However, this is possible by first converting to a different intermediate format.<\/li>\n\t\t\t<li>Choose the less secure 128-AES encryption when creating an ASIF disk image or directly converting one to another format. If you really want to use it with an older format, you can do a two-step conversion.<\/li>\n\t\t\t<li>See a determinate progress bar during operations on ASIF disk images.<\/li>\n\t\t<\/ul>\n\t\t<\/li>\n\t<\/ul>\n\t<\/li>\n\t<li>Additional updates for macOS Tahoe 26:\n\t<ul>\n\t\t<li><img decoding=\"async\" loading=\"lazy\" align=\"right\" width=\"128\" alt=\"Custom Volume Icon\" src=\"https:\/\/c-command.com\/dropdmg\/images\/3.7\/custom-volume-icon-tahoe%402x.png\" height=\"128\" \/>The <a href=\"https:\/\/c-command.com\/dropdmg\/help\/custom-volume-icon\">Custom volume icon<\/a> option\u2019s badging has been updated for the new mounted disk image icon\u2019s size and perspective.<\/li>\n\t\t<li>For apps that have not updated their icon for Liquid Glass, the <a href=\"https:\/\/c-command.com\/dropdmg\/help\/custom-volume-icon\">Custom volume icon<\/a> option will now use the source app\u2019s original icon to create the badge, rather than the \u201csquircle jail\u201d icon that macOS supplies.<\/li>\n\t\t<li><a href=\"https:\/\/c-command.com\/dropdmg\/images\/3.7\/dropdmg-window-detail-drawer@2x.png\" title=\"DropDMG Window: Log Detail Drawer\"><img decoding=\"async\" loading=\"lazy\" align=\"right\" width=\"161\" alt=\"DropDMG Window: Log Detail Drawer\" src=\"https:\/\/c-command.com\/dropdmg\/images\/3.7\/dropdmg-window-detail-drawer-thumb%402x.png\" height=\"96\" \/><\/a>Updated the window layouts, e.g for the new button sizes and window corner radius.<\/li>\n\t\t<li>Updated the documentation and screenshots.<\/li>\n\t<\/ul>\n\t<\/li>\n\t<li>DropDMG now tries to make sure the window\u2019s path bar is hidden when setting the layout of a mounted disk image.<\/li>\n\t<li><img decoding=\"async\" loading=\"lazy\" align=\"right\" src=\"https:\/\/c-command.com\/dropdmg\/images\/3.7\/dropdmg-icon-clear-light@2x.png\" height=\"128\" width=\"128\" alt=\"DropDMG Icon Clear\" \/>Updated the <a href=\"https:\/\/c-command.com\/dropdmg\/help\/signing\">Signing<\/a> section of the manual.<\/li>\n\t<li>Updated the French, Italian, and Chinese localizations.<\/li>\n<\/ul>\n\n<p>DropDMG 3.7 works with macOS 10.13 through macOS Tahoe 26.
