Apple - Problem Installing Boot Camp Windows Partition on new Mac Pro
Finally got this working, thanks to a person named "turbostar" over on discussions.apple.com:
- Re-run Boot Camp Assistant to remove the Windows partition and restore the full Mac HD as a single partition.
- Run a PRAM reset (restart, while screen is still black, hold down ⌘+Option+P+R and keep them pressed until you hear the startup sound a second time).
- Open disk utility and repair permissions on the Macintosh HD partition. TWICE.
- Start Boot Camp Assistant again.
Seems hokey. With those instructions I thought I would also have to stand on one foot, point to my nose, rub my belly, and hope for rain. But it did end up working.
@manuignatius and @Andrew Swift are correct. I had to install windows 10 on the newest MBP(15, 2018). Tried everything from other threads nothing and almost all version of versions of windows isos, nothing worked. But using the official Windows 10 image is the only thing that worked for me thus far.
I faced the same problem on my new 2018 15 inch MacBook Pro. None of the steps above helped me. However, while doing First Aid on Macintosh HD using Disk Utility, I noticed that I was getting the following error: "Warning: crypto: val object (oil:0x04): invalid state".
This was not going away, no matter how many times I did First Aid. While searching for a solution, I read (here: https://forums.developer.apple.com/thread/89882) that one way to fix this issue is to reinstall MacOS. Below are the steps that worked for me, in the exact order.
- Reboot machine and go to "Internet Recovery Mode" (Press option + cmd + R while startup)
- Connect to internet, select Disk Utility and select Macintosh HD.
- Erase the drive using default options. (Warning: You will loose all data in your machine)
- Close the utility and go back to the starting screen and select "Reinstall MacOS"
- After installation (this will take some time) and minimal setup, download 64-bit Windows 10 iso from Microsoft website (https://www.microsoft.com/en-gb/software-download/windows10ISO)
- Reboot the machine, do a PRAM reset (Press option + cmd + P + R while startup)
- After booting up, open Disk Utility and do a First Aid. Confirm the error is no longer there.
- Open BootCamp Assistant and follow the normal procedure.
The rest of the Windows 10 installation was smooth for me. Hope this helps.
