Re: Apple haven't made a decent device since 2012
Indeed. My 2012 15in MBP is what is being used to type this. It is a good job that I can touch type as the lettering on half the keys has worn off. It gets a log of use day in, day out and hasn't missed a beat.
For example, I have been pounding away these past few days writing my new Novel (any pubs out there, get in touch as I ain't paying Amazon 70% of revenue). 57,000 words this month alone.
As for MacOS 10.15... Not had any issues with it at all. I do use it for Photo Editing as well as wordsmithing.
