I have plenty of experience using Linux as a host OS and as a guest OS. I like using VirtualBox for Ruby on Rails development because of its ability to save snapshots. In my early days, I found this indispensable for installing Ruby on Rails. I still like VirtualBox for Ruby on Rails development, because it allows me to save a snapshot of a fresh installation. When I think I've finished an app, I have easy access to a fresh Ruby on Rails installation where I can try out my app and make sure that I've included all dependencies in the *.gemspec/Gemfile and that the setup procedure in my README file is complete. I'm surprised that using VirtualBox isn't standard operating procedure. I have been learning to develop Ruby on Rails on a Mac (I learned the Linux way first), and I have installed Linux as a VirtualBox guest OS on my Mac. However, I've been unable to install Mac OS X Mavericks in a guest OS on my Mac OS X Mavericks host. I've followed procedures I found online for creating an ISO file from the installation file (which I got by downloading but not installing the installation file from the Apple store), but OS X didn't boot up on the guest system. I just ended up with an empty black screen. Has ANYONE here SUCCESSFULLY installed Mac OS X as a guest OS? Exactly what procedure did you follow in creating the ISO file? Or could it be that the ISO file isn't the problem, and I missed some critical detail in the boot up process? Yes, I was so spoiled by Linux. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
