Work on 10.10.5?

[Rezask]

Hi there,

I am a beginner at Terminal. I have a Mac Mini 2014 with a 4K Monitor. I tried to change the refresh rate to 60hz.
When I researched, I realized that I should install this patch which I am a very beginner at it!
Does it work at Yosemite 10.10.5? and by running the command does it mean that I should enter each line separately and hit enter or enter it all at the same time?

Thanks,

Your mac handles 4k fine without this patch :)

Thank you for your replay.
It works fine with refresh rate of 30hz but I can't change it to 60hz!
I found the following link to solve my problem and it drives me to here!

Am I missing something?

What cable are you using?

[Rezask]

I am using Thunderbolt to DisplayPort.

Hm, should be fine, that cable is just mini displayport to displayport. Your thunderbold port can behave like normal minidisplayport.. Try running the script, you should use my port of this project because this one is not being maintained.. Or my version 2 script.

I could run the script though. It asked me my password and then installed something. However, my problem is still exist. Because I couldn't change my resolution on SwithchResX.
This is an annoying problem. Could you please help me about this issue?
