Today I am sharing about a mac book . The MacBook starts at $1, 299 for a model with a 1.1 gigahertz dual-core Intel Core m3 processor, 256 gigabytes of flash storage, and eight gigabytes of memory. ( A machine with a 1.2gHz Core m5 processor and more flash storage will cost you $1, 599.) You can also upgrade even further, and pay more, for a 1.3Ghz chip with a greater turbo boost
