AutoCAD for Mac, like any powerful design software, stores temporary files and cached data to improve performance and speed up workflows. Over time, however, this cache can accumulate outdated or corrupted files that may cause slowdowns, crashes, or unexpected behavior. Clearing the AutoCAD Mac cache is a safe and effective way to resolve many common issues—provided it’s done correctly.
In this guide, we’ll walk you through the steps to safely clear AutoCAD’s cache on macOS without risking your project files or settings.
Why Clear the AutoCAD Mac Cache?
Common reasons to clear the cache include:
- Slow performance or lag when opening files or using tools
- Unexpected crashes or freezing
- Display glitches, such as missing icons or rendering issues
- Problems with updates or new installations
- Corrupted temporary files interfering with normal operation
Clearing the cache forces AutoCAD to rebuild necessary temporary files with fresh data, often resolving these issues.
Important: What Not to Delete
Before proceeding, understand what not to delete:
- Your drawing files (.dwg) – These are your actual projects and should never be in the cache folders.
- Custom templates, tool palettes, or CUI files – These are typically stored in your AutoCAD support folders, not the cache.
- Preferences or license files – Deleting these may require reactivation or reconfiguration.
The cache consists of temporary, non-essential files that AutoCAD can regenerate as needed.
Step-by-Step: How to Clear AutoCAD Mac Cache
1. Quit AutoCAD Completely
Make sure AutoCAD is fully closed:
- Click AutoCAD > Quit AutoCAD from the menu bar, or
- Press Cmd + Q while AutoCAD is active.
Verify it’s not running in the Dock or Activity Monitor.
2. Open Finder and Access the Cache Folders
AutoCAD for Mac stores cache data in several macOS system directories. Use the following paths:
a. Application Support Cache
~/Library/Application Support/Autodesk/AutoCAD [Version]/
Replace [Version] with your installed version (e.g., “2024”).
Tip: To access the Library folder (which is hidden by default):
- Open Finder
- Hold the Option (⌥) key and click Go in the menu bar
- Select Library
b. Caches Folder
~/Library/Caches/com.autodesk.AutoCAD[Version]
Example: ~/Library/Caches/com.autodesk.AutoCAD2024
c. Temporary Files (Optional)
While macOS manages temp files automatically, you can also clear AutoCAD-related temps:
/tmp/
Look for folders starting with “AutoCAD” or “adsk.” Only delete these if AutoCAD is closed.
3. Delete Cache Contents (Not the Folders)
- Navigate to each of the above directories.
- Select all contents inside the folder (Cmd + A).
- Move to Trash (Cmd + Delete).
- Do not delete the parent folder itself—only its contents.
Caution: Avoid deleting anything outside these specific paths. Incorrect deletions can affect other applications or system stability.
4. Empty the Trash
Once you’ve moved the cache files to Trash, right-click the Trash icon and select Empty Trash to permanently remove them.
5. Restart AutoCAD
Launch AutoCAD again. The application will automatically regenerate necessary cache files during startup. This may take slightly longer than usual the first time—this is normal.
Additional Tips
- Backup First: While cache files are safe to delete, it’s always wise to back up your important drawings before performing maintenance.
- Use AutoCAD’s Built-in Reset (Optional): AutoCAD for Mac includes a “Reset AutoCAD” option under AutoCAD > Preferences > Application. This resets settings but does not clear the file cache—use it in combination with the steps above for a deeper refresh.
- Regular Maintenance: Consider clearing the cache every few months or after major macOS or AutoCAD updates.
FAQ: Clearing AutoCAD Mac Cache
Will clearing the cache delete my drawings or custom settings?
No. The cache contains only temporary files such as thumbnails, temporary render data, and session logs. Your .dwg files, custom tool palettes, workspace configurations, and preferences are stored in separate support directories and are not affected when you clear the cache as described in this guide.
How often should I clear the AutoCAD Mac cache?
There’s no fixed schedule, but it’s a good practice to clear the cache:
- After a major macOS or AutoCAD update
- If you notice performance degradation or graphical glitches
- Every 2–3 months for heavy users
Clearing it too frequently isn’t necessary and won’t improve performance beyond normal operation.
Can I automate cache clearing on my Mac?
While macOS doesn’t include a built-in tool for AutoCAD-specific cache cleanup, you can create a simple shell script to delete the relevant cache folders and run it manually or via a launch agent. However, never automate this while AutoCAD is running, as it may cause data corruption or crashes. Always ensure the app is fully quit before running any cleanup script.
Does clearing the cache fix license or activation issues?
Generally, no. License and activation data are stored in secure system locations (e.g., /Library/Application Support/Autodesk/AdskLicensing/) and are not part of the user cache. Clearing the user cache won’t resolve licensing problems. For activation issues, use the Autodesk Licensing Troubleshooter or contact Autodesk Support.
What’s the difference between “Reset AutoCAD” and clearing the cache?
“Reset AutoCAD” (found in AutoCAD > Preferences > Application) restores interface settings, toolbars, and preferences to default—but it does not delete cached files like thumbnails or temporary graphics data. Clearing the cache targets performance-related temporary files. For a full refresh, you may want to both reset AutoCAD and clear the cache.
Are there third-party apps that safely clear AutoCAD cache?
Some Mac cleanup utilities (like CleanMyMac or OnyX) can remove general application caches, but they may not recognize AutoCAD-specific folders or could accidentally delete important support files. It’s safer and more precise to manually clear only the verified cache directories listed in this article rather than relying on generic cleanup tools.
Conclusion
Clearing the AutoCAD Mac cache is a simple, low-risk maintenance task that can significantly improve stability and performance. By following the steps above, you ensure that only temporary, non-essential files are removed—keeping your projects and customizations intact.
If issues persist after clearing the cache, consider checking for software updates, verifying your macOS compatibility, or contacting Autodesk Support for further assistance.
