Install OSX in VB

[OSX-inVB]

Dear All
I have successfully installed VB in My Macbook air .However i am facing some issue to install (Yosemite) in the Virtual box kindly find the technical details below


1) There is no CD drive in my Laptop
2) Even i manage to get external CD drive for my MacbookAir , Apple doesn't provide OSX installer in CD drive format so i cant instal Yosemite by using CD drive also in the VB

3) Virtual box doesn't support USB bootable (I am not sure weather the VB is supporting USB or not )

anyone please guid me to install OSX Yosemite in my virtual box.

Note : i am not good in command prompt solution .

Main Concern : Does VB support boot from USB ? Kindly help

1) There is no CD drive in my Laptop

Neither there is a 2nd computer inside your laptop, but you still want to install one . That's why it's called virtual...

2) Even i manage to get external CD drive for my MacbookAir , Apple doesn't provide OSX installer in CD drive format so i cant instal Yosemite by using CD drive also in the VB

That can be arranged, assuming you've already downloaded the installer from Apple. See the script below.

3) Virtual box doesn't support USB bootable (I am not sure weather the VB is supporting USB or not)

Negative on both accounts. Starting with 5.1.x VirtualBox supports booting from USB. The client has to support/boot from EFI, which OSX not only does, but it has to. I haven't tried the USB booting personally (didn't have the need), and I can't say I've seen a successful report, but someone's got to go first.

Also, not only VirtualBox supports USB1 and USB2 for many years now, but, since version 5.0.x, USB3 as well.

Note : i am not good in command prompt solution.

Oops, too bad, because you're going to have to get your hands dirty. Don't worry, it's a copy/paste operation with minor modifications, if any.

Copy the contents of the script below. Your OSX installer is supposed to be in "/Applications/Install OS X Yosemite.app". If not, modify the first "hdiutil" line of the script. If you don't know, post the exact location and name of the installer app and I could fix it for you:

echo $ mv /tmp/10.10.cdr ~/Desktop/10.10.iso

This will leave you with a "10.10.iso" on your desktop which you can use to install 10.10 on VirtualBox.
