NTFS for Mac built on Apple's FSKit: no kernel extension, no macFUSE, no reboot, your Mac stays at Full Security. NTFS drives mount in Finder read-only by default; turn on Allow writing (beta) per drive after a backup notice. Hibernated, dirty or BitLocker drives stay read-only with steps to fix them in Windows. Open source (GPL v2), open beta for macOS 26+.
