macOS 26 "Tahoe" is due in a few days, and there are a whole four Intel Macs that will be able to run it: the 2019 MacBook Pro and Mac Pro, and the 2020 MacBook Pro and iMac. Those are the official models, anyway. As we covered back in 2023, the OpenCore Legacy Patcher project offers a free tool that lets you create a custom-modified macOS installer that will let you install newer versions of macOS onto Macs too old to officially support them.
The choice between Linux and MacOS isn't hard. If you can answer these questions, you'll know which to choose. Both are outstanding choices and will serve you well. I use both Linux and MacOS. The former is used for everyday tasks, and the latter for video editing and mobile usage (please, someone, create a Linux laptop that is as reliable and similar to a MacBook).
