Try upgrading the packages in your environment (] up in the REPL), Plots is a few versions old.
Although it is unlikely to be your problem, it is also worth upgrading to at least Julia 1.9.4 and preferably to the LTS release which is currently 1.10.8.
If neither of those changes anything, then this may be a problem specific to macOS, hopefully someone more familiar with that environment can provide more insight.
