Installing wxMaxima on macOS and Fixing the crash with plotdf() Function when calling wish tcl-tk

In this blog post, I'll guide you through the process of installing wxMaxima on your macOS machine and resolve a common issue related to the plotdf() function in macos Sonoma wiht maxima 5.47, and all other functions that call the tcl-tk interpreter wish.

The plotdf() Function Issue

MacOS Sonoma comes with a preinstalled Tcl-TK package. One problem you might encounter when using Maxima is that the plotdf() function or ploteq(), which is used for plotting differential equations, crashes. This issue arises because Maxima calls the wish script from the tcl-tk package, but the version of tcl-tk that comes pre-installed with macOS can be problematic.

There's an easy fix for this problem: installing tcl-tk and Maxima using Homebrew.

Step-by-Step Installation with Homebrew

Homebrew is a popular package manager for macOS that makes installing software a breeze. Follow these simple steps to install wxMaxima and resolve the plotdf() issue:

  1. Install Homebrew: If you haven't already installed Homebrew, open the Terminal application and run the following command: 

    /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

  2. Install tcl-tk: Once Homebrew is installed, run the following command to install the tcl-tk package: 

    brew install tcl-tk

    This package contains the wish script that Maxima requires for the plotdf() function to work correctly.

  3. Install Maxima: Next, install the Maxima computer algebra system by running: 

    brew install maxima

  4. Install wxMaxima: Finally, install the graphical user interface for Maxima with the following command: 

    brew install wxmaxima

    This step will also install any necessary dependencies.

After completing these steps, you should be able to launch wxMaxima by running wxmaxima in the Terminal. You can now use the plotdf() function without encountering any crashes or issues.

It works by breaking up your study time into small chunks, traditionally 25 minutes long, with short breaks in between. This method is named after a tomato-shaped timer that was used by the person who came up with it, Francesco Cirillo in the late 1980s.. The idea is to work hard for a short period, then take a quick break, and then start again. This can help you stay focused and productive, especially when you have a lot of work to do that requires a lot of concentration. The Pomodoro technique step by step Here's a step by step guide to using the Pomodoro technique: Choose a task that you want to work on. Set a timer for 25 minutes. This is called a "Pomodoro". Work on the task until the timer goes off. Take a 5-minute break. After four Pomodoros, take a longer break of 15-20 minutes. Repeat this process until you finish the task. Remember to avoid distr...
