In just over three days, MacHeist has raised US$50,000 for eight high-profile international charities. Touting this week as “The Week of the Independent Mac Developer,” MacHeist began selling a software bundle of some of the hottest apps for Mac OS X on Monday in the hopes of increasing the profile of the Mac shareware development community as well as raising $100,000 for charity before the holiday season. Now, only halfway through the week, MacHeist is on pace to meet its fundraising goal.
