Before we start
Deleting DYLD files just because they are taking up a huge amount of space on your Mac is not the best idea to free up space. If you need to free space on your disk, use MacCleaner Pro.

MacCleaner Pro will help you recover valuable disk space by finding and removing all types of junk files that are safe to remove from your Mac. With the app, you can remove applications and browser caches, uninstall unused applications, remove remaining files of already deleted applications, find and remove duplicate files, and more.

What is the DYLD Mac Library?

Every time you boot up your Mac, the system creates cache files, which are named DYLD. DYLD caches are used for a safe and fast Mac startup. They are system files, used for all user accounts on a Mac.

On the macOS, a DYLD folder is stored in the system library folder. On old macOS systems, you could find it in the /private/var/db/ location. Despite changing the location for storing DYLD files, the purpose of these files is still the same.

In the screenshot below, you can see an example of where the DYLD folder is stored on macOS Monterey:

/System/Library/dyld/

Is it safe to delete the DYLD folder on your Mac?

Since DYLD files are a system-shared cache, it is not safe to delete them. Don’t delete the DYLD folder or even a single DYLD shared cache because it can damage your system and create errors when you boot up your Mac.

Moreover, if you delete DYLD files, the system will automatically create new ones because they are needed for the correct system processes. Thus, it makes no sense to delete these files to recover disk space on your Mac. It would be better to remove other junk files, such as unused applications, leftovers of previously removed applications, duplicate files, browser caches, and other unneeded files.


How do you figure out when the DYLD library is not loaded on your Mac?

It happens very rarely; however, even with a reliable macOS system, you can face an unexpected error when the DYLD library is not loaded. It might happen due to system errors, an outdated cache, or if you removed DYLD shared cache files. Try one of the solutions below to fix the error with your DYLD library.
