My Macbook is 1.8 GHZ Intel core 2 DUO with 2 GB DDR2 SDRAM, version 10.7.5. I'm not sure what year I got it but it's old.
I'm not able to perform an update to the most current version and I don't know why.
The reason I want to upgrade is that apps will not let me do an install on this OS version. I tried installing a different OS, like Linux or Windows, but it did not go well.
It runs really well so I'm wondering if it has reached its end.
