I have an error 43 when trying to delete a folder in Mac OS - I have read that to fix this I need to reset the NVRAM - to do that I need to boot with Command OptionP R - however, this makes the startup noise continually until I release the buttons.

So far so good, but when I do release (I tried after 2 and after 3 startup sounds) - it just boots directly into Windows.

How can I make this work?

    In what context are you seeing "error 43"? That's entirely too vague. – Allan Aug 14 '17 at 1:12
  • It also seems to be something of an XY Problem – Tetsujin Aug 14 '17 at 6:26
  • What do you mean with "make it work"? Which result do you expect? – nohillside Aug 14 '17 at 7:54
  • I want to boot with command option p r - but it keeps booting into windows rather than booting into mac os when I do it. So I want to get command option p r to work when bootcamp is installed. – niico Aug 15 '17 at 10:20

    You don't boot with Cmd-Opt-P-R, that's used to reset the NVRAM. Period See my answer to boot into macOS. I am assuming you are attempting to delete a folder in Windows and getting "error 43". *Which version of Windows? Keep in mind - we are not there to look over your shoulder. It's essential you describe what you are doing, how you're doing it and in what environment. – Allan Aug 15 '17 at 11:23

Resetting the NVRAM won't make your Mac boot into OS X, which is what I am assuming you want to do.

What you need to do is hold down the Option key when booting and then select the macOS partition as your startup.

If you want to boot into macOS from Windows directly, you have to right click the Bookcamp icon and select "Restart in OS X"

  • No I want to reset the NVRAM because I have an error 43, as I said in the question?! That tip about restarting in OS X is very useful though thx. – niico Aug 14 '17 at 9:40
