I have an older iMac, without a true retina display. I want to be able to scale the user interface like the retina macs do, but I can't seem to find a way to do that. screenshot from Apple Support

Does anyone know a way to trick the computer into thinking it has a retina display, so the options are available in the Display PrefPane? That, or some utility that might let me access those settings.

Note, I'm not really talking about HiDPI mode, I've done that, it only has the option of pixel doubling. I want the variable scaling that is available on true retina displays.

I'm running mountain lion on a 2.5 GHz i5 iMac, about 1.5 years old.

Well variable scaling is just a fancy way of adjusting the DPI, right? – duci9y Jan 7 '13 at 9:05
Um, I suppose? but enabling HiDPI mode doubles the pixels with no other options, whereas the retina displays give a sliding scale as to how big you want the interface elements to be. – marcus erronius Jan 7 '13 at 14:58
@MarkHubbart With you can set your resolutions to things you've never seen before, including a HiDPI mode, which is as close you can get to a Retina Display on a standard computer. – Simon Sep 15 '13 at 15:16
Um thanks, MarketingBot, for that comment that's actually clipped directly from the app's website. Pretty sure I made it clear that HiDPI isn't a solution :/ Pixel doubling (which is what HiDPI mode does) on my 1920x1080 display leaves me with a minuscule 960x540 screen area; too small for most things. – marcus erronius Sep 22 '13 at 21:24
Any updates on this with the latest Maverick? – yurkennis Oct 23 '13 at 14:47

No, its missing the requisite hardware support.
