I have a newly refurbished Grade B MacBook Pro 2016 15" i7 16GB RAM with 500GB NVMe. It has been newly imaged and updated running MacOS Monterey. This is the latest MacOS version supported by Apple on this computer, however there are some 3rd party tools that will allow upgrading to newer MacOS versions. Also, this is an Intel processor so it will support installing Windows via Bootcamp.
I've installed Logic Pro along with the entire sound library. I would suggest using this MacBook as an offline studio machine only for security reasons as Apple is no longer patching MacOS Monterey.
This would make for a solid stationary or mobile off-line studio machine. Included 87W power supply.
