SheepShaver
SheepShaver is a classic Mac emulator for running PowerPC-era Mac OS software and older applications on modern computers.
What is SheepShaver?
SheepShaver is a Macintosh emulator used to run PowerPC-era classic Mac OS environments and software on newer systems. It is commonly used by retro computing enthusiasts, preservation projects, and users who need access to older Mac applications or games that no longer run natively on current macOS versions. On Mac, it provides a way to launch and work with compatible classic Mac OS installations inside an emulated environment rather than on original hardware. Typical uses include opening legacy productivity tools, testing old software, and revisiting vintage Mac games and workflows. SheepShaver is part of the long-running emulation community around classic Apple platforms, and users generally pair it with their own compatible system software and ROM resources to complete setup.

Safety overview
Status: Mostly safe
SheepShaver is legitimate emulation software, but it works closely with disk images, shared folders, and legacy system files. That access is normal for an emulator, though you should still use software and disk images from sources you trust and keep important files backed up before experimenting. Because it runs older operating environments, stability and compatibility can vary, especially with modern macOS versions and newer hardware.
Recommendation: Keep SheepShaver if you use older Mac software, games, or preservation workflows. If you no longer need classic Mac emulation, you can remove it like other apps; doing so will also remove convenient access to any emulated environments and related legacy setups you created around it.
