This has been spotted by Two MacRumors readers. Buyers configuring the MacBook Pro, MacBook Air, iMac Pro, iMac, Mac Pro and Mac Mini will be charged roughly 10% more than before for each upgrade.
For example, on the MacBook Pro 16″ if you choose an upgrade from the standard 2.3GHz configuration (Turbo boost upto 4.8GHz) to the 2.4GHz (Turbo boost upto 5GHz), it will cost £200 in U.K. instead of £180 earlier.
Likewise, upgrading from 16GB of memory to 32GB of Memory, now costs £400 instead of £360 earlier. Upgrading to 64GB of memory now costs £800 instead of £720 earlier.
