Apple has closed its store at the embattled Trumbull Mall, leaving the technology giant with six retail establishments in Connecticut. The former Apple storefront on the mall’s upper level has been boarded up, with a departing message from Apple, following the closing on June 20. Apple had announced in April its decision to leave the mall, ending a stay that began in October 2014. Apple also closed stores in Towson, Maryland, and Escondido, California, on June 20.
