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.

Ratings and Reviews

Alright, would expect more configurability for $2.49..


Having only one other display option in the quick menu (without opening a subsequent menu) holds it back, I often change between the default retina mode, the second highest scaling and the highest scaling modes that the MBPr 15inch offers. Also having zero configurability makes the app not exactly worth the price. In saying that, it does make changning resolutions much easier than opening the system preferences.
I do appreciate that you can just hold command key and press the application icon and it will change the to the previous used resolution, making changing extremely fast and simple :)

Now definitely more useful on a Retina MBP!


Version 1.1 has definite improvements over 1.0 for MPB Retina users - all of the resolutions are now in the drop down menu, and the two "sticky" resolution options are the most recent two you've looked at. This is a very useful app if you need to regularly change resolutions.

Looks like the developer was listening…what more can you ask for? Thanks! :)

HiDPI for non retina screens


As far asI know it’s the only ultility to activate HiDPI on non retina screens whihc can be a cool thing to do for say a 27” iMac (especially if you have older eyesight).
