Since about 2000, the IDE has been mostly localized into a variety of languages including German, French, Italian, Spanish, Japanese and Chinese. I say “mostly” localized because property names that appear in the Inspector, for example, have never been localized as this would create confusion when you go to use them in your code. However, a mostly but not completely localized product is not very helpful especially when the documentation itself is not localized.

We have discovered what we believe to be a bug in OS X Mavericks specifically on newer Macs. Apple started using Intel’s new Haswell processor in the MacBook Air in June, the iMac in September and the MacBook Pro in October. When you build for either Windows or Linux from OS X, any images you dragged into your project are converted to BMP format. The bug we discovered (which we have reported to Apple – RADAR case 15546907) results in a banding of the converted graphic.
Today’s laptops and monitors support high resolution displays which allow you to pack more information and content on the screen. Although one common complaint is that people find the text to be too small at the maximum resolution, Windows’ solution to this is the ability for the user to adjust the DPI setting.
