Scale 1680x1050 on rMB without an app

Sorry this post has become such a jumbled mess from what it originally was but there is now a script by a dev on GitHub that automates a lot of this, and after some fiddling I got it working with Big Sur PB1 this morning.

Check this post out for a Big Sur walkthrough:


Edit - beingninformed works with Mojave and 2017 mb so enjoy!

Check System Preferences->Displays->Profiles->Color LCD->Open profile->Line 17

The only thing we care about here is the 610 and the a027 though your numbers may be different (i.e. there are different manufacturers out there)

NOTE: If on OS X 10.11 Golden Master (GM) candidate or presumably with subsequent builds from there too as this post ages over time, need to disable 'System Integrity Protection' from recovery mode first before making changes to the DisplayProductID file, follow this post and you will then be good to go and set up for success with this mod:

We will want to navigate to /System/Library/Displays/Overrides/ in finder if on Yosemite (see the next paragraph break for file structure of El Cap for the file) and choose the folder that corresponds with your first number, mine being 610. The folder I want is called DisplayVendorID-610.

NOTE: If on El Capitan, you can find it in /System/Library/Displays/Contents/Resources/Overrides

Inside you want to find the corresponding files with your second number, mine being a027. The file I want is called DisplayProductID-a027.

To avoid dealing with getting rights to the file, we will just make a copy on the desktop and modify that. After that, open the copy you just made on the Desktop in TextEdit. Within the <array> portion you will want to make a new line and paste in <data>AAANIAAACDQAAAAB</data>. This is the data for the 1680x1050 HiDPI resolution. Save this file. This can also be the last line in <array> without issue

Then you want to copy and paste the original DisplayProductID-a027 (or whatever your folder name is) somewhere else as a backup for piece of mind should you prefer (i put mine in documents folder), otherwise paste in yours from the desktop to that original folder (so its overwritten). Make sure the name matches exactly or it will not work.

Reboot your machine and switch the resolution in system preferences-> displays

**If you want to see what 1680x1050 scaled looks like, or the RDM 'status bar dropdown toggle' app for 1536x960 listed below/ easy access to toggling resolutions without going into system preferences, here's a sample pic**:

most of this guide is borrowed from https://www.reddit.com/r/apple/comments/2ia242/_/cl0c87l and modified to fit within context of rMB/El Capitan and clarify some things
--------------------------------------------------------------------------------------------------------

add on instructions for 1536x960, a middle ground between 1440x900 and 1680x1050 (as you might expect)
this resolution requires an app that 'lives on the status bar as a drop down toggle icon' but its free and once you set the resolution if you so desire you can exit the app its just to kick it into the mode you want it i've found it really benign and small footprint in my experience, it's called RDM and by a jailbreak dev so much love (and would edit title if i could but i can't):
https://dl.dropbox.com/u/87351306/RDM.tar.gz

Add this line to the last part of that string of arrays in the file (whereas 1680 we made as the first string of that):
<data>AAAMAAAAB4AAAAAB</data>

reboot, start RDM-> go to system preferences>security>open anyways, select it in drop down from menu bar-> profit



Subnote- if on OS X 10.12, reboot holding cmd+r to be in recovery mode, open terminal and type "csrutil disable" to disable system integrity checker to be able to c+p the new file to that folder,

Once done, do "csrutil enable" in recovery mode to re-enable that protection

not sure how helpful this will be, its a joy to look at on the screen itself. at night when I'm half asleep sometimes i switch back to 1280x800, but i think 1440x900 and 1680x1050 now are gonna be my day drivers

neither as far as I can perceive

if you don't like this setting added in system prefs, just remove the data string and reboot again and back to normal.

its definitely worth giving it a try

Thanks for this. Man, the screen real estate is fantastic, but I do find that many things are just a bit too small for my tastes. From far away, there isn't any noticeable blurriness, but up close it's definitely more noticeable than 1440x900.

i don't notice any difference in clarity toggling between 1440 and 1680.

maybe having font smoothing enabled is making the difference, after all in the "?" part of font smoothing (under System prefs-> appearance) it specifically states smaller text is harder to read with that setting.

Give that a try?

its nice having the option for sure

When I added the 1680x1050 line, my display preferences only shows 4 options. Did it only show 3 options before?

Click to expand...

no it was 4 before, its just 1440x900 was the max (far right). now the lowest option has knocked off afaik, everything moved down one (or to the left of that scaler menu) and 1680x1050 took the place of where 1440x900 option used to be (far right)

terrible explanation but hope that helps. I'm half asleep this morning

glad to help people out and that you guys are liking it

This is awesome. Thanks for the tip.

So by changing this, it drops the retina fonts or whatever people were talking about when using custom fonts, right? I've used the display menu apps, and don't notice a difference, but throwing it out there for my OCD friends.

eh its just not native/2 scaling (1:1 mapping) but neither is 1280x800 the default option since 2304x1400 is the native resolution technically going 1152x700 would be the one. But i don't see a difference, especially with font smoothing off (check box under appearance in system prefs). ymmv on opinion on that one but i'm picky with screens too.
