macOS Tahoe: working fully-offline unattended install
The base image (macos.images.tahoe.upstream) now installs and boots end to end with no dependency on Apple's servers — proven on the KVM host: the finished qcow2 boots standalone (OpenCore from its own ESP) to the macOS 26.6.2 loginwindow. Install driving (vm-driver.py, screenshot + OCR over QMP): - map the whole InstallAssistant.pkg as a raw disk and dd it byte-exact into the app as SharedSupport.dmg (it is a pkgdmg: xar + koly footer — the bare xar member fails startosinstall with "pkgdmg is missing a footer") - offline install: no NIC + /etc/hosts blackhole of Apple install/verify endpoints so startosinstall's calls fail fast instead of hanging (SecureBootModel=Disabled allows the sealed-volume install offline) - keep the recovery display awake with a tiny mouse jiggle; coarse settle fingerprint so the cursor is not seen as a change - guest watchdog re-erases/retries a startosinstall attempt that stalls or runs too long (prepare is intermittently slow) - disk-aware boot watchdog: QMP system_reset only when the screen is dark AND the disk is idle (never interrupts a slow-but-working boot); recovery-restart if a post-prepare reboot lands back on recovery - detect the bright loginwindow and power the VM down (install complete); a black + disk-idle screen is treated as a completed halt - copy OpenCore into the image ESP so it boots standalone recovery.file pins a content-addressed local BaseSystem.dmg (Apple's CDN load-balances Sequoia/Tahoe during the rollout). fetchRecovery retries to the pinned hash when used instead. Not yet done: .generalize (user creation) — the first-boot agent LaunchDaemon is blocked by Ventura+ Background Task Management on headless boots; next step is offline user injection from the agent pkg postinstall.
