hi i have macbook pro i install window 8.1 on it but i want to back on mac os how i can install mac os again
Maybe your Mac has support for the automatic recovery process. Really it depends only by the model, if you have a recent Mac it should be easy, so what is the 'magic' number?
Thank you, I knew that. What I asked for was the 'model' number of his|her Mac in order to give a little more help. But is great to see how in this community the help goes so quickly .
I don't think there's any other way besides this or using your Apple ID. For cases like this, I think it's always best to leave a smaller partition for Mac OS just to be safe.
I facing the same problem like this. Let me check out some useful advises posted here. Thanks in advance if it is works.
We should use BootCamp to install Windows. With this way, MAC OS X is still there. If MAC OS X has been removed, we need to a bootable MAC OS X device (typically USB or DVD). I think we can buy or create one by asking someone who having Mac OS X.
