I'm getting ready to upgrade my MacBook Pro from Snow Leopard to El Capitan, but I want to be able to keep running MT-Newswatcher, so I want to run SL in VirtualBox. I followed the directions at this site


and everything seemed to be going well through step 4. After it went through the SL Installer, I clicked on Restart. But then it shows a screen saying I need to restart again. I can't seem to get past this.

I'm using the retail Snow Leopard disk I bought years ago. Could this be because I'm installing regular Snow Leopard and not Snow Leopard Server?

I also tried the additional steps here:


specifically the additional lines in ~/Library/VirtualBox/VirtualBox.xml

  <ExtraDataItem name="VBoxInternal2/EfiBootArgs" value=" "/>
  <ExtraDataItem name="VBoxInternal2/SmcDeviceKey" value="ourhardworkbythesewordsguardedpleasedontsteal(c)AppleComputerInc"/>

Now I don't get that screen, but when it tries to boot I get

Could the problem be due to the version of VirtualBox? I was hoping to get the VM working before I upgraded my Mac, and the latest version of VB that runs on Snow Leopard is 4.2. When you're creating the VM, OS X Snow Leopard isn't listed in the Version menu, as I see in most of the web sites that show how to do this. So maybe I need to switch to El Capitan first, install VB 5.0, and install it again.

  • @user3439894 I've read that I can purchase Snow Leopard Server from Apple. But when I search for it on the Apple website, I just find this which seems to be the same Snow Leopard that I already have. Do I have to go to eBay to find it?

  • aha, just read here that SL Server can only be purchased over the phone, not online.

  • I just got off the phone with Apple and you want to call 866-752-7753 and the Part # is MC588Z/A and it's MAC OS X 10.6.3 SLSVR UNLCL SING LIC-INT and if they're having trouble finding it tell them it's under tech solutions. Jun 5 '16 at 23:34
