Disk Jockey4.1.1

Create and inspect disk images for vintage computers and emulators, using Disk Jockey to prepare media for real hardware or virtual machines. Disk Jockey 4.1.1 is freeware in the System Tools category for macOS, running natively on Intel and Apple Silicon Macs with Dark Mode support and sandboxing.

It creates device images for Snow, BlueSCSI, and PiSCSI, plus volume images for Floppy Emu, Basilisk II, and Mini vMac. Supported material includes HFS+, HFS, and MFS volumes or partitions; Disk Copy 4.2, Disk Copy 6 NDIF, 2IMG, ISO, Toast, and SP2SD images; ProDOS floppy, hard-drive, volume, and partition images; DOS 3.3 and UCSD Pascal media; Atari TOS images in raw ST, FAT12 ST, and MSA formats; TOS hard-drive images; HDF files for WinUAE; and partitions inside hardfiles made with tools such as HDInstTools for Workbench, as well as sampler disk images.

It can produce blank, zero-filled images, convert Basilisk II images for BlueSCSI or Snow, replace a Lido SCSI driver with a classic driver, and extract partitions from device images for insertion into new devices. Users can export image structures as JSON, extract files from supported formats, inspect file details, and browse contents in hexadecimal; the Inspector also displays Degas, Degas Elite, NEOChrome, Tiny Stuff, and Spectrum 512 pictures and saves them as PNG.

The current release includes fixes for older macOS versions, menus and keyboard shortcuts for most functions, and a complete rewrite intended to improve resilience and future extensibility. It suits retro-computing enthusiasts, emulator users, and owners of period hardware who need to move, examine, or adapt disk media across systems.
