# Cannot boot macOS without the USBÄ«y default, the OpenCore Patcher won't install OpenCore onto the internal drive itself during installs. Once you've booted OpenCore at least once, your hardware should now auto-boot it until either an NVRAM reset occurs, or you remove the drive with OpenCore installed. Reminder that the option will be called EFI Boot. To resolve this, ensure you're booting OpenCore before the macOS installer in the boot picker. This means macOS has detected an SMBIOS it does not support.

The upgrade option (HD 5870) is also, currently, unavailable. The card is an ATI Radeon HD 5770 and currently it would seem that no new cards are available in the uk market place. I have tried a number of alternative start-up options such as Safe Mode, etc, but none of these makes any difference, presumably because the keyboard isn't being read. I have checked that the display is operating correctly by connecting to a MacBook. While the computer was still working I checked the hard drive SMART status and it was showing "Verified". The timescale of the failure, from occasional flashing screen to complete failure to boot took less than a day. The keyboard and the USB ports are inactive (the Caps Lock key doesn't light when pressed).

Now on switching on again the hard drive makes the usual noises, fans are running, the chime sounds, and then the display shows either a black or grey screen, or a screen full of fine multicolour vertical stripes. Eventually the Mac failed to boot at all. Allowing the Mac to cool down for half an hour initially allowed the Mac to boot properly but then it would only stay on for a few minutes before going black/grey/multicolour screen again. There being no further activity the only option was to force shutdown by pressing the power button for a few seconds.

With no prior warning, the display started to flash occasionally, then switched into a grey or black screen mode. My Mac Pro, after just two years and one month since purchase from Apple, appears to have fried its graphics card.
