Hi my name is ***** ***** to Just Answer. I am reviewing your question and will reply ASAP.
The minimum recommended system for installing this app on a Mac include having OS X 10.9 or later installed.Full recommended specs can be double checked here:
Installing this on your Mac therefore seems to be impossible. Are you certain you cannot install 10.9? Is it a hardware limitation?Click the Apple menu and About This Mac.
What type of Mac is it and what does it say there for Processor?
Thanks in advance.
