Without OCLP, the latest release of macOS that a 2015 MacBook Pro will run is Monterey (5 releases ago).
The final release of Monterey was July 2024. So no, it is not getting updates anymore. Worse, many programs require a newer release of macOS to run at all.
This is a perfect system to migrate to Linux. It will run faster, be more secure, and will have totally up-to-date software.
Trade is essential. It is not really optional.
So, the trick is to find the best trading partners.
I would rather not trade with China. That said, China is currently a better bet than the United Staes.
China is more conservative and takes a longer view. They want stability. They offer consistency and determinism. The United States in contrast offers chaos.
Of course China will act in their self-interest. But at least they believe that a stable and dependable global trade system is in their best interest. They will be predictable. You can anticipate their interests and plan around them. As such, they make a far better trade partner than the US.
