The Universal compatibility and Power Mac
By Harry Johnson
10 July 2006, The combination of Mac hardware and software has been exceptionally consistent over the years, providing an ease of use that Mac users have enjoyed. With a Windows emulator such as Virtual PC, Macs can also run Windows and DOS applications. Since the mid 1980s, it has been essentially a Mac vs. PC world for personal computers, with Linux-based PCs gaining ground after the millennium.
Mac mini: -
The more recently announced Apple's Mac mini has been turning some heads, even in the PC world. If the iMac G5 is basically a 1U server attached to a monitor, the Mac mini is basically a reorganized laptop without a monitor The Mac mini is especially relevant to this article because a lot of the discussions about performance with regards to Apple's PowerBook will apply directly to the Mac mini, as the two platforms are very similarly configured.
OS X Tiger: -
The more I read about OS X Tiger, the more interested I become. The two main features that draw me to the update are Apple's system-wide, fully indexed search engine, called Spotlight, as well as the fact that in Tiger, every single pixel on the screen will actually be rendered by the graphics card. For the most part, in OS X Panther, all of the rendering work is done by the CPU, with some GPU accelerated compositing occurring. In Tiger, everything is done through the pixel pipelines of your GPU, increasing the dependency on a graphics card with fast memory access, as well as increasing the flexibility of some of the effects that you're able to do in the OS itself.
Given Tiger's reliance on very high GPU performance, I would almost expect Apple to celebrate its release with a new G5 platform - with PCI Express graphics. That may be a bit of wishful thinking.
New features included by apple
There are new RAW adjustment controls in the Adjustments Inspector and Adjustments HUD that improves the quality of RAW decodes via custom tuning of parameters. Most noticeably, you can control contrast (using the new Boost tool) and sharpness, as well as color noise reduction from the RAW decoder.
Apple gave us a new Color Meter tool that quickly and easily samples any area of an image for RGB, CMYK, or LAB color values. You can use this as a stand-alone tool or as part of Aperture's Loupe tool. Photoshop users who like to sample specific color ranges will feel right at home in Aperture due to this new tool.
For those who never felt comfortable with Aperture's printing parameters, the new version has updated image resolution controls. You can specify output resolution in dots per inch (dpi) when exporting images or sending images to an external editor and Aperture 1.1 has increased the maximum size of images displayed in the Browser. You can resize the display of images in the Browser up to a maximum of 512 pixels in height or width.
There is an attractive feature included by apple that is Universal Compatibility that means Aperture 1.1 runs natively on both Intel-based and PowerPC-based Macintosh computers. I tested it on both an Apple G5 Dual Core PowerMac with four gigs of RAM and a new Mac Book Pro 2GHz model with two gigs of RAM. I've seen Aperture run on a PowerBook, and there's no denying that it runs much quicker on the Mac Book Pro.
