Installing XP on latest MacBook OS X My MacBook (purchased in 2007) with Windows XP installed through VMware software. I have some important software that works only in XP. My MacBook broke down and I purchased latest MacBook Pro (2015).

I am not able to install Windows XP because the Mac does not allow installation through USB or CD drive. Also OS X help seems to suggest that it won't support XP in Boot camp. Can anyone help me out?
If I understand correctly, you just need to install VMware Fusion first, which will allow you to install and run Windows XP as a virtual machine, so that you can install and work with that important software of yours.

If you still have a backup copy of your old XP virtual machine (it's a large single file, if I remember correctly), you should be able to run that. Again,  after you have installed VMware Fusion.

Installing Windows using BootCamp is a very different thing (dual booting) and is indeed not supported for XP anymore.
