Short answer

com.apple.mediaanalysisd is the macOS service that analyses your photos and videos for faces, objects and text search. Its cache normally stays small, but on some macOS versions it has grown to tens of gigabytes. The cache is rebuilt on demand, so clearing it is safe; your photos are never stored here.

**Location:** `~/Library/Containers/com.apple.mediaanalysisd/Data/Library/Caches`

## What’s inside

-   Analysis caches for Photos search (faces, scenes, text in images)
-   Temporary model files used during analysis
-   No original photos or videos

**Our verdict: Check first.** This may be the only copy of something. Look at the details before removing.

## Clear the cache

1.  Quit Photos.
2.  In Finder, choose **Go › Go to Folder** and open `~/Library/Containers/com.apple.mediaanalysisd/Data/Library/Caches`.
3.  Move the **contents** of that folder to the Trash (leave the folder itself), then restart your Mac.

macOS rebuilds what it needs in the background; Photos search may be slower for a day while it re-analyses.

## If it fills up again

Make sure macOS is up to date: the runaway growth was a bug that Apple fixed in later updates. You can check its size any time in Tidy Mac’s **Space Map**.
