The short answer
No.
Not ShareX itself. ShareX is a Windows app, and every ShareX download is for Windows. The ShareX Team is building XerahS, a free cross-platform version with Mac downloads, but its site says it's in early development and most functions are still being worked on. PrintScreen.ly runs natively on Apple silicon Macs (macOS 14 or later), and on Windows and Linux: region, window, full-screen and scrolling capture (scrolling on Linux needs an X11 desktop), a markup editor and on-device text grab, with your screenshots in one private library across your computers and your phone. It records your screen to MP4 too (Linux on X11), and each recording stays on your computer.
Free for 24 hours: every feature, no card.

No. ShareX runs only on Windows. The ShareX Team's cross-platform version, XerahS, has an early Mac build.
Yes, inside a Windows virtual machine, but it then captures the Windows desktop inside the VM, not your Mac's own windows.
No. PrintScreen.ly uploads to your own private library, which your phone and the web open too.
If you're staying on Windows and you like building your own capture pipeline, stay on ShareX: it's free, open source and deep. PrintScreen.ly is for the moment a Mac joins the mix: a native Mac app, the same account on your Windows PC and Linux machine, and one screenshot library across all of them.
