Thanks for the info', guys.

I'm actually in the market for an older MBP, don't have one yet, and is why I'm asking.
I'm already heavily invested in a Windows & Android ecosystem here at the house (
and the local family households as well) so I'm not looking at switching* but I'd really love to have a MBP that I can use for testing the web sites using Safari running on native MacOS.
Last time I had to debug an issue with Safari I ended up using the
Mac in Cloud VM service provider. At $20/mth it wouldn't be bad but even with my 75/75 connection at the house I'm getting some lag using the VM and life would be easier having access to a physical machine.
* = Even though I'm entrenched in Windows for my laptops most of what I do these days is online so it's getting to the point that I could & just might switch in the future. Every few years or so I consider it, when my current Dell XPS 15 UHD dies I'll consider it again.
