DropDMG 3.7
DropDMG 3.7 updates my app for creating and working with Mac disk image files for macOS Tahoe 26. This version adds support for Apple Sparse Image Format (ASIF) disk images and Liquid Glass icons.
Some interesting issues were:
Kenichi Yoshida redesigned the app icon, keeping the same concept but adapting it for the Liquid Glass style and macOS’s new volume icon. As a utility app, it uses a gray squircle.
I’m not in general a fan of Tahoe’s menu item icons, but I think they work pretty well in DropDMG’s File menu. These are concrete commands that straightforwardly map to icons, and most of them already used these same icons in the toolbar, anyway.
Tahoe changes the mounted disk image icon for the first time since Big Sur, so DropDMG’s badged icons now use a different size and perspective.
ASIF disk images ended up being a lot more work to support than previous new formats. This is because they’re manipulated using
diskutilinstead ofhdiutil. The two tools take different command-line arguments and don’t support all the same features or handle edge cases in the same way. I’ve tried to make ASIF appear in the user interface as just another format, but under the hood it’s using different tools (or combinations of tools) for different operations. There are lots of different combinations of source and destination formats, some of which require special handling.There seems to be a Tahoe bug related to Auto Layout for toolbar overflow that can cause a crash. It doesn’t like directly resizing the window to a much smaller size, e.g. because of restoration at launch or because you dragged the window corner too quickly. If the app is crashing at launch, you can reset the saved window size to avoid the problem. I’ve also adjusted the initial window size for new installs.
