Apple doesn’t have many new products that are user accessible and user upgradeable. Wil Gomez runs through the list:
Goodbye, upgradeable Macs. No upgrades for you, technology lover. In fact, if there is any way to upgrade anything in the MacBook Pro it seems best relegated to a member of the nearby Apple Store Genius Bar. You can’t even upgrade the SSD, let alone the RAM, and not even the battery.
That may be a troubling sign and the end of an era.
iPhone and iPad? No upgradeability. MacBook? Nope. Watch? Uh uh. What you buy is what you get; you’re stuck with peripherals and that’s about it. Other than software upgrades, of course. Apple TV? Nope. Mac mini? Maybe. But not without some trepidation, a little sweating around the brow, and Steve Jobs’ ghost hovering over you.
New iMacs have user accessible RAM and the Mac Pro circa 2013 can still received RAM and storage upgrades, but not CPU.
