ResolutionTab is a menu bar app for fast switching between Standard & HiDPI display modes.

Modern apps and websites should look great on Retina displays, so we have to test them in both standard and ultrahigh resolution modes. But when you configure your display in System Preferences, it takes plenty of time to switch from the standard to the HiDPI mode and vice versa. ResolutionTab is a minimal app living in the menu bar that toggles your Mac between Retina and non-Retina resolutions in one click.


— 15" MacBook Pro Retina is compatible with HiDPI modes by default, so ResolutionTab will work out of the box.

— 11" MacBook Air is not compatible with HiDPI. The screen is too small, so resolution would drop below the minimum required by OS X.

— In all other cases, you have to enable virtual HiDPI modes manually.

Here is how to do this with Administrative privileges:

1. Launch Terminal app located in your /Applications/Utitlities folder.
2. Type sudo defaults write /Library/Preferences/ DisplayResolutionEnabled -bool YES.
3. Log out and log in again.

Done. HiDPI is activated and ResolutionTab will work properly.

Does what it says, and well


This is a great lil app for the price. On my 15" Retina it easily allows me to switch from my usual default of the "Looks like 1920 x 1200" in the Apple Pref Pane to the Full 2880x1800 of the retina display- and the full spectrum of display options in between.

The big selling point for me was that it allows quick toggle between these "custom hires modes" that it enables and the default pref-pane based resolution. The other resoltion app, "Display Menu" gives you access to the custom hires modes but forces you back through the standard display prefpane to regain 1920x1200 hidpi mode, which is a pain after about the 4th switch.



This app does not work at all on my MacBook pro 13”! I want my money back! I know it’s only $2 but it’s the principal. I tried all the tutorials on their website on how to make this work and none of them worked. I even sent their customer support an email about 2 weeks ago and didn’t receive an answer back. I went on their website and it says nothing about compatibility issues with a MacBook Pro 13” only a MacBook Air 11”. Their support website is a joke they only have 3 Frequently Asked Questions listed and no public discussion. Don’t bother with this app, no support, does not work. Apple should revoke their developers license, they are making the App Store look bad.

Works as advertised


I got this app to test some UI work in HiDPI mode and it seems to work flawlessly. The initial setup should probably display the information on enabling HiDPI mode instead of burying it under “More Information…” in the “HiDPI mode not available” dialog, but maybe I missed that info somewhere else.
I like the fact that in a multi-monitor setup like mine, one monitor can be set to HiDPI mode while the other one isn’t.
Simple, cheap, works great: 5 stars.
