My Mac was bought in 2010.
Upgrades arrive automatically.
Same machine still cooks 10 years later.
Sure... If all you do is post here. I have a 2011 Macbook Pro that is essentially a paperweight for anything other than posting on the internet.
And that is AFTER I upgraded memory and RAM. Which... you can’t DO on newer Macs... Which is not a good selling point BTW...
