I just downloaded the latest Webkit nightly and noticed it is no longer a universal binary application and does not run on PowerPC Macs. So just a warning to PowerPC users. DON'T UPDATE YOUR LATEST VERSION OF WEBKIT OR YOU'LL HAVE AN UNFORTUNATE SURPRISE! IT WON'T WORK AT ALL! Fortunately, the previous nightly build r89812 which is a universal binary is still available. But don't download r90316, the latest. It is INTEL ONLY. It could be an upload error, I don't know. I found no news on the site to confirm that the change was deliberate. The question begs though. Does this mean the imminent end of Safari support for PowerPC Macs? If so this would be a very sleazy move by Apple considering they still support Windows XP. It would make Apple's support for Safari better on Windows machines than for lifelong Mac owners like me that still have both Intel and PowerPC Macs, basically a kick in the balls to loyal Mac owners and buyers.
