It has run for years and is still very fast (especially with its new SSD drives). It's just that, damn it, I'm attached this old tower. I have a MacBook Air and I could afford to buy a new Mac. ROM? According to the MacTracker app, my tower has a Intel Xeon 5400 series ("Harpertown") processor. Is there another way to go about this? What does the Sierra installer check to know whether the machine is supported? If I were to find a way around this, is there some hardware-related reason why Sierra wouldn't run on this machine? E.g. Please switch to XPC or bootstrap_check_in(): Įven after exchanging emails with DosDude, we weren't able to resolve the problem. However, the installer disk it creates hangs during boot with the error: Can't get kexts port.Ĭom.489 Warning: Endpoint has been activated through legacy launch(3) APIs. I have tried the Sierra patch tool from DosDude.

I know it is not supported, but as the machine itself is no longer supported by Apple, I don't really care. I would just like to install Sierra on my unsupported Mac Pro Tower early 2008.
