1401 and NVIDIA driver 1.4.0

Something not working? nullmothsystems.com/help lists every known problem and exactly what to do.

Driver / Mac

Screen flicker at login is cleared automatically. The first time the desktop comes up after a boot, the driver gives the compositor a clean restart, so the strobing many people saw at the login screen and first minute is gone. (Opt out by creating the file /Library/NullMoth/no-wsreset.)
If your screen still flashes when you change refresh rate or use two monitors, Send logs — 1.4 captures exactly what each display is doing (its refresh rate and the driver's frame timing) so it can be fixed for your setup.

PCs whose ACPI tables crash the disassembler build anyway. Some firmware made the tool crash outright; 1401 now records the crash and keeps the firmware table so the build continues and the exact table can be looked at.
Partial hardware scans are accepted. A scan missing the USB or Storage Controllers section no longer gets the whole report rejected; the build continues.
Carries everything from 1.3: stick-write and erase fixes, the EXITBS boot-freeze ladder, basic display for unsupported-only PCs, and resume-from-last-byte downloads.

16 GB RTX 50 black-screen fix, hot-plug monitors, Blender, Geekbench OpenCL, macOS 15 and 26 installer, pre-Turing cards left alone.

macOS 15 Sequoia. Requires OpenCore.

Two displays or above 60 Hz can still flash on a refresh-rate change until the automatic restart; Send logs if it persists.
Glitches in local video played with hardware decode (QuickTime); a slow cursor on some laptops.
