macOS Mojave下Tkinter 8.6系统崩溃问题在Catalina中是否已修复？

Hey there, let's break down your problem and possible solutions here:

1. macOS Catalina Compatibility with Tkinter 8.6 #

From what the developer community has shared, this specific Tkinter crash issue tied to CGSTrackingRegionSetIsEnabled errors and WindowServer port conflicts does appear to be resolved in macOS Catalina. Many users who upgraded from Mojave to Catalina reported that their Tkinter scripts ran without triggering system crashes anymore. Apple addressed several low-level GUI framework compatibility bugs in Catalina that were disrupting Tkinter's interaction with the WindowServer—this was almost certainly the root cause of your crashes.

Since you're already planning to upgrade, this should be your go-to fix. Chances are you won't need to keep troubleshooting the Mojave setup once you move to Catalina.

2. If the Issue Persists in Catalina (Unlikely, but Just in Case) #

If for some reason you still run into problems after upgrading, here are a few solid alternatives:

• Use a custom Python distribution: Skip the system Python and install Python via Homebrew (brew install python) or Conda. These distributions bundle their own updated Tkinter versions (often newer than 8.6) that play nicer with modern macOS releases.
• Switch to an alternative GUI library: If Tkinter continues to give you trouble, consider options like PyQt5/PySide2, PySimpleGUI (which wraps Tkinter, Qt, and others), or Kivy. These libraries have more robust macOS support in many cases and avoid the low-level system integration quirks Tkinter sometimes hits.

3. Mojave Temporary Workarounds (If You Need to Use It Before Upgrading) #

Since you mentioned safe mode works, that points to a conflict with a third-party kernel extension or startup app interfering with Tkinter's access to WindowServer. If you need to use Mojave temporarily before upgrading:

• Disable non-essential startup items: Head to System Preferences > Users & Groups > Login Items, remove all apps you don't need to launch automatically, then restart your system. This eliminates potential conflicts with software that hooks into the GUI system.
• Update Tk separately: Try updating Tk via Homebrew (brew install tk), then reconfigure Python to use this updated version instead of the system's built-in Tkinter. Note that this can be tricky with the system Python, so using a Homebrew-installed Python alongside it is the safer route.

It’s totally normal that you didn’t find a straightforward fix for Mojave—this was a niche, low-level bug that Apple didn’t patch in later Mojave updates, so upgrading was the most reliable solution for most users.
