Modify "SystemVersion.plist" within MacOS Sierra

I have an older version of Pro Tools that requires Mac OS v10.7+ but isn't capable of understanding x.10 is higher than x.7.

Pro Tools Error

Therefore, the only thing left to do is buy a new copy (no) or change the Operating System's version number. Here's how:

Step 1 - Disable System Integrity Protection

A. Restart your Mac and boot it in recovery mode by holding down CMD + R.

B. Open up Terminal and type

 csrutil disable

C. Restart the computer.


Step 2 - Modify your Mac's version number

A. First things first, let's create a backup:

sudo cp /System/Library/CoreServices/SystemVersion.plist ~/SystemVersion.plist.bak  

B. Open up SystemVersion.plist using nano and set it to write mode.

nano -W /System/Library/CoreServices/SystemVersion.plist  

C. Modify these two nodes:

<plist version="1.0">  

D. Save your work and install Pro Tools.

E. Once you get passed the initial installer, don't forget to undo your work by repeating steps 2.b and 2.c.
