Optimized Software Builds Bring Out the Best in Your Mac, Dan Knight, Low End Mac’s Online Tech Journal, 2009.06.30.With a new hard drive, the iMac is running as well as ever. The iMac was getting slower and slower, and Disk Utility kept trying to fix the same problems. Computer disaster ends happily, Alan Zisman, Zis Mac, 2009.08.05.

The 15″ MacBook Pro with antiglare could be the perfect Mac, but the iMac also has much to commend it.

This is a big step forward from 24-bit color (8 bits each for red, green, and blue) in providing improved color gradation without banding. Update: With OS X 10.11 El Capitan, all Retina iMacs support a new 30-bit color mode with 10 bits per color channel. That’s only $500 more than the 3.4 GHz 27″ non-Retina iMac.
We should probably be most impressed that Apple was able to offer such a cutting edge display in a US$2,499 machine. Hence the 5K Retina iMac with twice the vertical and horizontal resolution of the “regular” 27″ iMac. That said, 4K resolution (4096 x 2160 pixels) is the extra high definition of the future, and to properly edit 4K video, you need a display that has room for all the controls a video editor needs. After all, the regular 27″ iMac already has a 2560 x 1440 pixel display, which goes well beyond HD TV quality. You really have to wonder what Apple was thinking by releasing an iMac with a 5120 x 2880 pixel Retina Display.
