However, all three computers are now exhibiting hardware failure and repair shops are unable to keep repairing them, despite me being happy to pay a premium for this service. I have been keeping this MacBook Pro and two other backup Apple laptops which run Snow Leopard (another MacBook Pro and a MacBook).
I require Snow Leopard to work and run a lot of software which will not run on later versions of Mac OS X. I have a MacBook Pro, 2011 vintage, running Snow Leopard and have VirtualBox 4.2.36 installed, with the extension pack (I believe this is the latest version of VirtualBox to run on Snow Leopard?).
