| Issue | Solution |
|-------|----------|
| Boot Camp Assistant says “USB drive cannot be partitioned” | Use a different USB drive (some USB 3.0 drives fail). Try a USB 2.0 drive or an external SSD. |
| Windows installer can’t see BOOTCAMP partition | In Windows setup, load drivers → browse to USB:\WindowsSupport$WinPEDriver$\AppleSSD → load driver. |
| No Wi-Fi after driver install | Mac Pro 6,1 has no internal Wi‑Fi? Actually, it has 802.11ac. Reinstall BroadcomNetAdapter driver from Boot Camp manually via Device Manager. |
| Black screen after Windows logo | Boot into Safe Mode (F8). Disable AMD graphics driver temporarily, then reinstall Boot Camp drivers. Also try resetting SMC (unplug power cord for 15 sec). |
| Windows clock wrong when dual booting | Windows uses local time, macOS uses UTC. Fix: In Windows Registry – HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation → add DWORD RealTimeIsUniversal = 1. |
| High fan noise in Windows | Mac Pro 6,1 fans ramp up due to missing thermal management. Ensure Boot Camp drivers fully installed. Use Macs Fan Control for Windows as a workaround. |
