Silverlight 1.1: No Love for PPC Macs

John Lam of Microsoft has written a nice blog post called “Clearing the air about Silverlight and the DLR”. In it, he confirms that the final version of Silverlight 1.1 will not support PowerPC Macs:

  • 9. Silverlight V1.1 will only target Intel Mac OS X machines.

This is unfortunate but not surprising. Making .NET work on PowerPC would cost Microsoft time and money. According to this report, Apple sold 17.2 million PowerPC Macs running OS X between 2001 and 2005. Numbers for Intel Macs are a little less clear but seem to be in the 10-12 million range. Bottom line is that they’re blowing off half of the Mac installed base for the sake of their programmers’ convenience. Guess Bruce Chizen was right to question their commitment to cross-platform, huh?

On a more positive note, John Lam’s post also reveals that the new JScript implementation from Microsoft targets ECMAScript 3, which is the same version of ECMAScript supported by Flash Player. It’s great to see Microsoft doing something positive w.r.t. JavaScript/ECMAScript after ignoring it for so long (the ECMAScript 3 standard was published in 2001), even if they are just following our lead. Maybe Microsoft will even start contributing to ECMAScript 4 efforts soon…

  1. By the way, a big tip of the hat to Jon Gruber of Daring Fireball for the link to this post. It got an amazing amount of traffic, 2 and 1/2 weeks after I originally wrote it. Just goes to show the difference between the traffic between an A-List blogger like Jon and a C-List blogger like me…

  2. […] Sheba Nation tell how Microsoft have shown their contempt for PowerPC Mac users by confirming that their Flash challenger, Silverfish, won’t provide support for that platform.

The reason I only was able to have a quick peak is because I am still rocking a power PC mac and unfortunately with Silverlight 2, which PUSH is using it is not compatabile with Power PC macs. […]
