Issue transitioning from - Macos 10.15.7 on Intel iCore i7, python 3.10 --- to Apple M3 Max, OS 14.6, python 3.12.3: issued package installs to correct import errors. python program executes without throwing any errors/ warnings, but delivers different results. It is a pandas dataframe data manipulation program with read/write from/to excel using pd.read_excel and pd.ExcelWriter.
Can you check which engine are you using on both platforms? Or try to use for example engine="openpyxl" for reading and writing on Intel and a M3. Also check which engine(s) is actually installed on both machines. Another idea could be to check out Pandas code from git - https://pandas.pydata.org/docs/development/contributing.html#version-control-git-and-github (for the version you are using) and try running a test suite there - https://pandas.pydata.org/docs/development/contributing_codebase.html#running-the-test-suite Some tests may fail, as per documentation, but this can give some interesting insight. Otherwise the option of the last resort - to present a minimal reproducible test case demonstrating your problem. Marcin
