Replace the screenshot/OCR/keystroke driving of Apple's Recovery with a "PE": BaseSystem.dmg (a journaled HFS+ volume, writable from Linux) with one LaunchDaemon added (makeRecoveryPE) that runs /Volumes/VMIX/run.sh as root at boot, records the status and powers off. launchd loads it alongside its signed cache (verified on Tahoe 26.6.2); same idea as AutoNBI/Imagr NetBoot images. - makeImage: the PE runs vmix-install.sh (erase, installer app, SharedSupport pkgdmg, startosinstall). Progress is read from the serial console (boot-args serial=3 -v, VMIX-* markers) and screenshots (brightness only). Fully offline; prepare now takes ~5 min instead of ~10. - customizeImage: boots the PE with the image attached and runs the template offline against the mounted System/Data volumes; OpenCore ScanPolicy restricted to HFS+/SATA so only the PE can boot. One PE boot ~30 s. The installed macOS is never booted for customization, so nothing depends on launchd/BTM approval or a first-boot agent (removed). - templates rewritten for offline use: generalize creates the user with dscl -f (admin, home, auto-login kcpassword, Setup Assistant suppression, hostname, locale, timezone, keyboard type, container resize); remote-access, no-updates, performance edit the target's plists. - makeBootDisk: build-time OpenCore variant (serial console, ScanPolicy). - vm-driver.py rewritten: passive observation only (serial markers, kernel boots, panics, brightness), disk+serial-aware hang watchdog, reboot-death reset, halt/loginwindow detection. No OCR/tesseract. - OpenCore: four SMBIOS DIMMs for MacPro7,1 (no "Memory Modules Misconfigured" warning). - tools/soak.sh: repeatability harness. Verified on daku: base install 23 min end to end; basic + generalize in three ~30 s PE boots; the result auto-logs into the desktop with the created user. Root cause of the "first-boot hang" (from the serial log): the guest's restart path panics (IOPlatformHaltRestartAction -> AppleSMC, SMCWDT smcWriteKey kSMCBadCommand, nested panic) because the pinned OSX-KVM Lilu disables itself on macOS 26, so VirtualSMC never loads. Handled by the driver (reset within 60 s); kext update to follow. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XsESshRCoBoUVWV9qKURUF
