1401 and NVIDIA driver 1.3.0

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

Mac app

Send logs no longer freezes the app. Collecting runs in the background (a few minutes); the app keeps working. In 1.2.0 the whole app hung while it collected, so most people could not send logs at all.
Installing no longer sits at "Finding the OpenCore partition." The password prompt runs in its own process and always shows.
Setup finds the partition your Mac started from by its serial number, instead of asking you to pick it.
"Remove NVIDIA driver" asks first. In the boot picker it waits for Y; any other key, or 60 seconds, changes nothing. The screen stays on while the driver is off.

No more black screen / crash loop on 16 GB RTX 50 cards. Under heavy graphics load the driver could abort the whole desktop (WindowServer) on an RTX 5060 Ti / 5070 Ti. Fixed.
A monitor plugged in after you log in now lights up instead of staying dark until a restart.
Blender 4.2 starts instead of crashing.
Geekbench's OpenCL test no longer crashes on RTX 30 and 40 cards.
Pre-RTX cards (GTX 10 and older) are left alone. The driver only runs cards it supports (RTX 20 / Turing and newer); on an older card macOS keeps running on the firmware's screen instead of going black.
Sent logs now keep the whole boot (the driver stopped filling the log with routine messages).

Apple downloads finish on networks that cut connections. Some networks close every download after 1 MB; 1401 keeps what arrived and continues from that byte (1.2.0 stopped with "stream ended at 1048576/10485760").
Reuse a stick that has macOS or Windows on it — 1401 names what is on it and asks before erasing.
Sticks that fail to erase or format are handled: the partition table is cleared first, a refused write retries with the disk taken offline, formatting falls back to the built-in formatter, and the stick is found again by serial after erasing (fixes "the requested object could not be found," "Windows error 1," and disks that change number mid-write).
PCs that freeze at the hand-off to macOS (EXITBS:START). With the stick plugged in, 1401 reads its startup logs and steps through the memory settings that get past it, on Intel and AMD.
Unsupported-only PCs build anyway. A PC whose only card is a GTX 10, RX 7000 or Arc now builds and runs macOS on the firmware's screen (basic display, no acceleration) instead of stopping.
macOS shows in the OpenCore picker without pressing Space.

macOS 15 Sequoia. Requires OpenCore.

Two displays, or a refresh rate above 60 Hz: changing a display's mode can make a screen flash until you restart. If this hits you, send logs from the Mac app and post the report ID in the Discord.
Glitches in the first minute after login, and a slow cursor on some laptops — send logs if you see them.
