I’m been using an M1 Max Macbook Pro 16 Inch, with 64GB RAM and a 2TB SSD, for a year. I bought it used on eBay for a great price, and the seller was telling the truth when he said he kept it in pristine condition—it was like new. The specs might have been overkill for my lightweight use (mainly web browsing, text editing, email, Photos, the Music app, no external monitors so far, etc.), but I wanted to anticipate keeping it for years.
Everything I run on it is still fast, except when I don’t close unused tabs in Chrome often enough and I wind up with 350 or more tabs open, at which point Chrome runs a little slower, but still surprisingly well. But oddly the more tabs I have open in Chrome, the slower the ChatGPT app gets in sending me responses.
My 95 year old mom and my brother are still using their 2020 M1 Macbook Airs, 8GB RAM, with no performance issues, but they mainly use them for things like web browsing and text editing too. My mom is better than me at her Chrome tab management—she doesn’t like to keep more than about five tabs open at a time.
If Apple wants more turnover, they’ll need to focus more on bringing new, useful features to new models, and dramatically improve existing features, since most people are pretty satisfied at this point with the performance of their M series and late Intel series Macs.
