Accessibility Inspector vs Bochs

Accessibility Inspector is Apple’s free macOS tool for examining accessibility information in app interfaces. It displays an element’s accessibility properties, available actions, and position in the view hierarchy. Audits identify common issues such as insufficient contrast, clipped text, and missing descriptions. Results can be saved as HTML reports containing summaries, screenshots, issue descriptions, and fix suggestions. Accessibility audits can also run in UI tests through performAccessibilityAudit(for:_:). The target menu includes apps on Mac and selected iOS, iPadOS, watchOS, or tvOS devices. Open it from Xcode through Xcode > Open Developer Tool > Accessibility Inspector. Apple’s listing describes Xcode as Mac-only, requiring macOS 26.2 or later and an Apple M1 chip or later, and labels it Free. Clearing reported issues does not prove complete accessibility; Apple recommends additional checks with assistive apps such as VoiceOver.

Bochs is a free, open-source emulator that models IA-32 x86 PC hardware. It can simulate Intel CPU families from 386 through x86-64, common I/O devices, and a custom BIOS, allowing users to run guest systems such as Linux, DOS, Windows, BSD, and other x86 operating systems. Optional command-line and graphical debuggers provide ways to inspect registers and memory or set breakpoints. Graphics support includes VGA, VESA VBE resolutions up to 2560x1600x32bpp, Cirrus Logic video, and four 3dfx Voodoo adapter models. Bochs also emulates USB controllers and devices, and can forward guest network packets to a physical network on several host systems. Multiprocessor simulation can be configured for up to 254 processor threads, but is experimental. The emulator uses a single-threaded simulation core and does not use dynamic code translation or virtualization. It supplies virtual hardware, not a setup wizard or guest installation disk, so users install guest systems themselves. Binary packages and source compilation are options; some features may require compiling it. It is available for Windows, Linux, and macOS, among other documented host systems.
