Beyond updating the MacBook Air and MacBook Pro, Apple on Tuesday also reduced the cost of SSD upgrades for all Macs, in some cases by as much as half.

For high-end 15-inch MacBook Pros, 1-, 2-, and 4-terabyte upgrades are down to $200, $600, and $1,400 respectively. The 4-terabyte option previously cost $2,800, more than many whole systems.

With the MacBook Air, Apple has removed a 1.5-terabyte configuration, narrowing selections to 256 gigabytes, 512 gigabytes, and 1 terabyte. The latter two choices are $200 and $400.

Similar price cuts have reached the iMac, iMac Pro, and Mac mini. On a 27-inch iMac for example, 256-gigabyte, 512-gigabyte, and 1-terabyte options are $100, $300, and $500.

Apple has often been criticized as overpricing SSD upgrades beyond what they cost from third-party vendors, especially versus equivalents on Windows PCs.
