Logic Pro Sound Library & Project Render Cache

Bottom Line: You can delete temporary audio render files, but use caution when deleting instrument libraries in /Library/Application Support/Logic.

What is the Logic Pro Cache?

Located at /Library/Application Support/Logic and ~/Music/Logic/, Logic Pro stores downloaded instrument patches, EXS24 sampler instruments, Apple Loops, and audio freeze track renders.

Can You Delete Logic Pro Files?

⚠️ Use Caution.

• Project Renders (Safe): Temporary freeze files and audio bounce caches inside project packages can be safely purged.
• Sound Library (Caution): Deleting sound libraries requires re-downloading gigabytes of instrument packs from Apple servers.

How to Manage Sound Library Storage

In Logic Pro: Go to Logic Pro > Sound Library > Relocate Sound Library… to move audio packages to an external drive.
