Does it do what you need for it to do?
Discussion
It does but it’s old. I have a new one. I was thinking of keeping this old one as my personal computer and the brand new one to work only. But sometimes I think it’s too much.
Up to you entirely but I would consolidate the two laptops in to one, much easier to just have everything you need on one laptop. If you then wanted to have separation between work and personal (providing you are self employed/manage the device yourself) you could have a VM (virtual machine) running for work bits and use the laptop itself (the 'host') for personal bits. Or there may better, other ways of doing something similar.. maybe even a built in utility, or dual boot? I'm not a big MacOS guy so can't say for certain.
