Can Anyone figure out why my brand new Imac is so darn slow it takes 1 min to boot and 1 min to shut down i did a hardware test everything is fine it came with mac os sierra so i upgraded and formatted it to APHS format or what ever its called and its worse then ever so slow programs crash i tried to return it back where i bought it from but they are out of stock a brand new computer should not be twice as slow as my late 2012 that the processor is slower then this one what a joke. I am stuck with a POS now that i can't return because I didn't buy it from apple.
