Should I update to the latest macOS on my Mid 2011 iMac?
I have not used this computer much at all over the last 2-3 years but will begin using it much more.
iMac (21.5-inch, Mid 2011)
Processor: 2.5GHz Intel Core i5
Memory: 8 GB 1333 MHz DDR3
Graphics: AMD Radeon HD 6750M 512 MB
Currently running macOS Sierra Version 10.12.6
Thanks!
