Can I use an old Mac (7,1) as a monitor for my new Macbook Pro?
I have been told by some people that this can work and some that it cant. But Im trying it anyways. My old Mac is just sitting powered off and gets no use. So I would like to use it as a second monitor for my Macbook. I bought an HDMI to USB cable. As well as the custom diplay port for the Mac (which I believe is calld a mini DVI? Could be wrong) but either way. Once they are all connected my desktop doesnt switch over. On my Macbook when I go to system preferences-displays-arrangement the second display shows up. Its detecting the desktop and I can even move things over there. It just wont show up. The desktop is just showing its usual background coming from its own hardware.
Hopefully thats all easy enough to understand. This is my first time posting on here so Im not entirely sure how it works. Hopefully someone can help me out. Thanks!
