Anyone know if its possible to use my 2012 Macbook pro (regular, not retina) as a 2nd monitor for my 2009 8-core Mac Pro? If it a software solution, the Mac pro is running 10.6.8 while my Macbook pro is dual boot to run 10.7 or 10.8. I plan on using it as a 2nd monitor while writing music, so it would host instruments, audio meters, etc. I would love to have it be as "lag free" as possible but it wont be doing anything graphic intensive. Thanks in advance for any solutions you can recommend.
