Enable HiDPI Resolutions on macOS

Enable HiDPI Resolutions on macOS

Works on OS X El Capitan 10.11+

Enabling HiDPI resolutions allows your display to run at full resolution but render the images at a smaller one. In a sense, it works like the Retina displays by scaling windows and programs to appear larger than normal. It is essentially the same as the scaling option in Windows, and it default in OS X Retina Displays. If you happen to 1440p or 4K screen, this can come in handy. This works at any resolution, but isn't useful below those resolutions.

BEFORE YOU START: Disable SIP (System Integrity Protection) on macOS

Method 1: Terminal

If you don't want to download anything and understand how to use Terminal, it is very simple. Open Terminal from Launchpad or Spotlight and copy the following command into it and press enter:

sudo defaults write /Library/Preferences/com.apple.windowserver.plist DisplayResolutionEnabled -bool true
 Method 2: Quartz Debug

Quartz Debug gives you many more features, such as an FPS counter and other visual modifiers. You can try it out by downloading the file from Google Drive. This option is for people who would rather be able to disable and reenable it at ease.

Download - QuartzDebug.zip


There you have it! HiDPI is enabled!

    1. Not for me, but it could be different depending on your situation. Download Quartz Debug here:

      And from that try enabling the HiDPI resolutions. Good luck!

  2. Not working for me. Using Quartz I have the HIDPi enable but they don't show in resolution option. Pressing the "option" key I have more resolution option but no HIDPI.

    1. rssfrncs - What resolution is your display? For my 4K display it's the non-HiDPI resolutions that are tagged. See http://imgur.com/a/MjUPG for screenshots.

Hackintosh Boot Flags

If this is your first time building or making a Hackintosh, boot flags may seem like a foreign concept. Once you understand what each of them means, you can get started!
Clover Boot Flags:Verbose Mode:

 -v 
Safe Mode:

 -x 
Single User Mode:

 -s 
Zone Postponing: (use if hanging)

 -no-zp 
Single CPU core mode:

 cpus=1 
No Kext Cache Mode: (When changing kexts)

 -f 
Disables VT-x or VT-d:

 dart=0 
Verbose Mode:

 -v 
Enable NVIDIA Web Drivers: (do not use with nv_disable=1)

 nvda_drv=1 
Disable NVIDIA graphics cards: (do not use with nvda_drv=1)

 nv_disable=1 
Kext Dev Mode:

 kext-dev-mode=1 
Rootless Mode:  Do not boot with this on El Capitan or macOS Sierra

 rootless=0  If you're stuck at [PCI Configuration Began]:

 npci=0x2000   npci=0x3000 
Set Maximum Memory (RAM): (In megabytes)

 maxmem=4096   maxmem=8192 
Troubleshooting: If you are having any trouble, first try this string. It works on a lot of systems with Intel HD Graphics to get into the OS X Installer from a Unibeast USB.

 -v -x -s -no-zp

Android vs. iOS - Usability

Android vs. iOSiOS 9 vs Android Marshmallow
Round 2 will be released next week, 4/17/16. Round 1: Usability Although my judgement is skewed because I use an iPhone 6 on a daily basis, I have used Android extensivly and have written tutorials on how to run it on your PC or laptop. Android Marshmallow has come a long way since 2011, when I dismissed it as an operating system not even comparable to iOS, dude to the lack of app support and specs that were better on paper than in real world usage.
Android:
Android Marshmallow is a very good operating system. It is lacking a few things compared to iOS, but the same can be said the other way around. It is hard to compare usability because Android is an operating system, and there is not a definitive version. The apps that come packaged with most devices can be broken down and compared to iOS quite easily. Every one of them is tolerable, and some are better than any alternative in the Play Store.
Updates - Most Android devices get updates for 6 …
