AUSTIN, Texas — John Mackey, chairman and chief executive of Whole Foods Market here, this week issued an online apology in his blog on the company's website for the trouble he caused though his pseudonymous postings on the Yahoo stock message board. He was recently cleared in a Securities & Exchange Commission inquiry about the postings, and last year was cleared by the company's board. He resumed his blog Wednesday after a 10-month hiatus. "I wish to apologize to all the stakeholders of Whole Foods Market, customers, team members, investors, suppliers, and our communities," he wrote. "I am truly sorry that all this has happened and put a negative spotlight on our company. If I could get a 'do over' on this one, I certainly would choose not to have ever participated in the Yahoo! online financial communities."
