PlistBuddy is missing

[ryanhatfield]

I haven't looked through the code yet, but it looks like the script relies on a file, PlistBuddy, to read and write to the display plists. This is missing on my particular install of OSX (reinstalled, fairly fresh) and i'm currently running OSX 10.12.4.

I've included the console output from me using this command initially:

Bob:~ ryan$ ~/enable-HiDPI.sh
 Multi monitors detected, please choose target monitor:
 [ 1 ] 0610::2ea0
 [ 2 ] 0dc3::3000

Any thoughts?

Looks like you have a method already for finding plistbuddy but it's never being called.

Turns out there is a file /usr/libexec/PlistBuddy on my system ... I can't make a symbolic link to the lowercase version, I'm not sure how case works on OSX ... is the script using strict case, whereas the system does not? More investigation is needed I think on my part but any help would be appreciated.

I updated the script, and changed plistbuddy to PlistBuddy. This got me a little further, but I still don't think it worked correctly:

Bob:~ ryan$ ~/enable-HiDPI.sh

 [ 1 ] 0610::2ea0
 [ 2 ] 0dc3::3000

Hello @ryanhatfield , this script got rid of plistbuddy now. We don't need any plistbuddy software anymore.

And, you should disable SIP first to make it work.
