Achieving Retina - Redux

I've already gone over how Apple enables Retina support on OS X so I'll point you back to the 15-inch rMBP review for a deeper dive into everything Apple did here. In short, the 13's default configuration approximates a 1280 x 800 display but with 4x the number of pixels. All UI elements and things like Finder windows are the same size they would be if they were rendered on a 13.3-inch, 1280 x 800 panel, but they contain 4x the pixels (and thus look awesome). Images and other non-scaled objects are mapped 1-to-1 with panel resolution. This allows you to display a 2500 x 1400 image in actual size (1:1 mapping, without zooming out) while still having perfectly legible menus, icons and text.

If you need additional desktop real estate, Apple provides two scaled resolution modes: 1440 x 900 and 1680 x 1050. At these resolutions, the desktop is rendered at 4x the scaled resolution (1440*2 x 900*2) and then scaled down to fit the 2560 x 1600 panel. Apple wrote its own scaling and filtering algorithms to maintain consistent quality across both Intel processor graphics and NVIDIA discrete graphics (15-inch rMBP). The added scaling and filtering work means there is a performance penalty to enabling these scaled modes, but in practice it's rarely that impactful. Also since you're performing a non-integer mapping of resolution to pixels on the downscale, there is some loss in quality but once again it's not hugely noticeable thanks to Apple's filtering algorithms.

Once again, UI elements, text, windows and icons are also rendered at 4x their size so everything remains legible, but things like images and videos remain unscaled allowing you to fit more content on your screen at the same time.

Similar to the 15-inch rMBP, Apple doesn't directly expose a native 2560 x 1600 setting although there are ways around that.


In using the 13-inch rMBP I found myself frequently switching between the native 1280 x 800 and two scaled modes. For basic web browsing or reading, the 1280 x 800 setting delivered the best overall experience. Everything was easily legible from a distance and quality was great thanks to 1:1 pixel mapping. The 1440 x 900 scaled setting was perfect for a combination of photo and typing work. Text was still large enough for me to comfortably see at a distance and the added desktop real estate made multitasking much better. Finally the 1680 x 1050 setting came in handy when I had a lot of applications open at once. It's easily the most impressive setting, but you have to have pretty good eyesight to be ok with doing a lot of reading/writing in this mode.

Switching between scaled resolution modes is very quick, although application and Finder windows don't retain their proportional sizes when moving between resolutions. For example, a full height window at the 1280 x 800 (Best for Retina) setting turns into a window that only takes up ~85% of the vertical height of the screen at 1440 x 900 (or ~60% at 1680 x 1050). I can understand why Apple does this, but it'd be nice to have the option to keep everything proportionally sized when moving between resolutions. Even better, I'd love to see some intelligence where only those windows that make sense to resize proportionally are touched between resolution changes.

Non-permanent image retention has been a part of both rMBPs launched thus far. Keep any static image on the screen for a long enough time and you'll see a ghost of that image even after the screen has changed. Apple attributes the image retention issues to its use of IPS based LCDs in the rMBP, however the severity of image retention can vary depending on a lot of factors. I've personally seen image retention happen on both 13-inch and 15-inch Retina MacBook Pros. In my use, image retention was never a significant issue with either the 13 or 15-inch rMBP although I suspect how bothersome it is depends a lot on the user and usage model. There have been numerous reports of LG based Retina Displays behaving worse in the image retention department than Samsung sourced parts, however I don't have access to a large enough sample size of rMBPs to really validate those claims.

    I just cannot understand Apple's spec selection for this laptop.

    They are selling this as 'Pro' laptop, with fixed 8GB ram, 128GB starting storage space (and HUGE overcharge for slightly more useful 256GB) and no external graphics.

    I don't think this is any better than recent full-HD ultrabooks from other brands, usually around $1000 price tag recently. 1080p is more than enough on 13" screen, and they provide cheaper storage upgrade option (256GB mSATA drives are now cheap around $200), and some even has external GPU. And face it - 2.5Ghz i5 won't give a huge performance edge over 1.8Ghz i7 ULV with turbo boost for most applications.

    Yes, I know it will still sell like hotcakes.

    That`s the only problem. Simply put, a dealbreaker, especially for mac users , that inherently have an above average need for virtual machines.

    Everything else is expected.

    Anand - the image retention flaw on the 15 inch rMBP is a real issue. I have written you several emails asking if you'd like to address this using your testing tools but never received a response. You haven't acknowledged this issue in this review either.

    Is the 13 inch rMBP subject to the same image retention flaw?
  • bji - Thursday, November 15, 2012 - link

    WHOOPS - I am wrong. You did address this, I just didn't see that paragraph somehow.

    It would still be great if you used the tools at your disposal to analyze this. There are reports that the heat of the display (air conditioned versus warm room) have an impact, and of course it's well known that only LG displays suffer this issue. Having all of that confirmed by a reputable reviewer would be great.

    I am trying to decide on a replacement for my 2gb mba 13" . The UI references including "Also if you're looking to minimize UI frame rate issues as much as possible you're going to want the upgraded CPU (although that still won't eliminate low UI frame rates)." truly scar me away from the rMBA. I am on my machine 12 hours a day regularly. the thought of the UI lagging scrolling on applications This is not something i noticed when i looked at the machine in the store but certainly something that would drive me batty once i have noticed it. I think I am going to have to think more about the MBA vs. the MBP non retina and pass on the retina for now.

    It's not really lag, just low frame rates. It works just as fast as it should but looks a pit more choppy while moving.

    Well, I'm one of those people who always complaint about "Pro" in 13" MBP/rMBP, it should be named MacBook, without Pro because it is not a Pro machine. And maybe we could get lesser complaint on Mac App Store comment section for 3D games just because they thought 13" MBP can do 3D game.

    As for 13" rMBP, here my two cents after using this thing for a month (I got it for free anyway, so...):
    - 8GB RAM is not an issue, period! You just trolling saying it needs 16GB! You just don't run 2 VM, 100megs AI files while running FCPX on this machine, you just don't do that.
    - 128GB SSD for $1799 laptop? This is annoying! Seriously? 128GB? And yet you still calling it a Pro? I'll be damn!
    - Display is awesome, super awesome, even though, I prefer to have 1440x900 resolution over native retina. The only thing I hate from 13" MB/MBP is the resolution barely usable for professional work. However, if you're iOS app developer or UI designer, this thing rocks! No more scrolling madness for testing app on retina simulator or designing retina artworks in Adobe!
    - UI performance is not an issue, at all, some websites simply just another prove of bad programming. And retina aware apps are widely available, if they're not updating their app to be retina aware until first half 2013, it means the app is either no longer under development or its developer simply not serious selling Mac apps.
    - Gaming or anything 3D? Forget about it. Unless of course, by gaming you meant Angry Birds, but for me, gaming is stands for Steam, AC3, Diablo 3 and the list goes on.

    So who is this for? Professional who does a lot of work developing or designing retina UI but hates 15" rMBP portability. Or, it could be great for business professional, you'll be thank to its retina display for saving your eyes for working too long in front of your computer.

    This is not for me, obviously, I switched back to my 15" rMBP after a month. This is well overpriced on my opinion, but then again, no competition whatsoever. And yes, please stop telling me ultrabooks $1000 etc, the closest ultrabook price with this thing is cost more than $1400! But then again, if you're making money with your laptop, why bother with price, as long as its beneficial for you to have this rMBP (also works for boosting confidence), just buy it and don't look back. Haters will be haters, don't listen to them.

    Grate in-depth review wish I found this 2 weeks ago
    I bought a maxed out air then sent it back after seeing the retina display in store.
    Since then I’ve been trying to decide if the upgrade to the faster cpu is worth it for the rMBP. Sounds like it is and as I am paying education prices which brings it in at £1383 (which still hurts but not as much as £1609)

    I would love to see a 13-inch "non-Retina" Macbook Pro with some of the goodies of the rMBP. For instance, I need the Ethernet port (yes, there is an adapter, but I'd rather prefer o have it out-of-the-box); I also like the battery life on the non-Retina model, and to have upgradable hardware is almost a must-have for people that don't buy a new notebook every year (for instance, me).

    In the other hand, I don't use the DVD drive on my computers since... I don't even remember. And the 1280x800 is a low resolution right now.

    But most important, I'd rather prefer to have a consistent fluidity through all the UI than more than a lot of pixels (yes, it's a nice display, but I'm not a photographer, it isn't a must-have to me) and the price. The price of the Retina model is just too absurd.

    Why don't make a 13-inch Macbook Pro with Air's display (a not Retina, but still good) and without DVD-tray (although I can live with it, would be nice to have more space for battery life)? That would be my dream machine.
