NO – this is NOT a scam. But it is not really a new MBP – this is how to make your old MBP feel like new.
How does it work? The answer is simple.
First – understanding why your older Mac is running slow.
Since the Macbook Air started using solid state drives (SSDs), slowly virtually all new Macs have moved to this storage. Instead of a disk that spins like a CD or a 45 RPM record, SSD is a bank of electronic memory. It is similar to the RAM in the computer, except that it does not loose all the data when shut down.
It is many times faster than the old spinning disks – and herein lies the problem.
