Apple has taken a step back in its efforts to reopen its stores around the world, with all six of its retail outlets in the US Michigan closed as a preventative measure. The six outlets in the state closed on Friday, confirmed by Apple as a temporary measure due to current Covid-19 conditions in the state. Store listings for the six confirm they are closed for the foreseeable future, with no indication as to when they will reopen to the public, reports AppleInsider. We take this step with an abundance of caution as we closely monitor the situation and look forward to having our teams and customers back as soon as possible, the company was quoted as saying.
