CLR Profiler is a free memory profiler provided by Microsoft for CLR applications. GlowCode is a performance and memory profiler for .NET applications using C# and other .NET languages. It identifies time-intensive functions and detects memory leaks and errors in native, managed and mixed Windows x64 and x86 applications. Visual Studio
Since the Old World ROM usually boots to Toolbox, most OSs have to be installed using a boot loader from inside Mac OS (BootX is commonly used for Linux installations). 68K-based Macs and NuBus Power Macs must have Mac OS installed to load another OS (even A/UX, which was an Apple product), usually with virtual memory turned off.
XNU ("X is Not Unix") is the computer operating system (OS) kernel developed at Apple Inc. since December 1996 for use in the Mac OS X (now macOS) operating system and released as free and open-source software as part of the Darwin OS, which, in addition to being the basis for macOS, is also the basis for Apple TV Software, iOS, iPadOS, watchOS, visionOS, and tvOS.
SheepShaver setup menu on Linux. SheepShaver is capable of running Mac OS 7.5.2 through 9.0.4 [1] (though it needs the image of an Old World ROM to run Mac OS 8.1 or below [5]), and can be run inside a window so that the user can run classic Mac OS and either BeOS, Intel-based Mac OS X, Linux, or Windows applications at the same time.
On Linux, a kernel panic causes keyboard LEDs to blink as a visual indication of a critical condition. [14] As of Linux 6.10, drm_panic was merged allowing DRM drivers to support drawing a panic screen to inform the user that a panic occurred. This allows a panic screen to appear even when a display server was running when the panic occurred.

A memory debugger is a debugger for finding software memory problems such as memory leaks and buffer overflows. These are due to bugs related to the allocation and deallocation of dynamic memory . Programs written in languages that have garbage collection , such as managed code , might also need memory debuggers, e.g. for memory leaks due to ...
tmpfs, a memory filesystem implemented using conventional in-memory data structures in order to improve on the performance of MFS, was merged into the official NetBSD source tree on September 10, 2005; [9] it is available in 4.0 and later versions. FreeBSD has ported NetBSD's implementation, where it is available in 7.0 and later versions. [10]
