From the update of 2025 in adobe reader on mac, pdf figures generated with matplotlib do not display text labels. Moreover, I have seen that the symbols of the enviroment itemize of latex do not appear in the compiled pdf.

In other pdf visors as chrome, this error does not happen.

All times I have reinstalled the new version of 2025, the error held. To solve this, I have installed the version of 2024 choosing an old mac osx system, and then works. Therefore, the error is in the current version of adobe reader.
