What is mdworker & mds?

Mdworker is a short form of metadata server worker which indexes your files to enhance the search process.  While Mds stands for the server of metadata which manages indexes to provide fast search results. These processors are part of  Spotlight, a search tool for Mac.

Why Do mds and mdworker Consume So Many resources?

If you have downloaded or transferred a lot of files on your Mac, then mds and mdworker start working on it, due to which they use a lot of resources. If you want to be sure of it, launch Spotlight and if you see Indexing on the search bar area, you must understand that both the processes are at work.

Note: The process could take hours, depending on your processor speed and hard drive. Well, Spotlight is not supposed to use excessive resources, especially when you are working on something that is CPU-intensive or consumes battery. However, it takes up all the resources needed, as and when your Mac is idle.

However, if these processes are taking a lot of time and are hogging CPU resources. then the index might be corrupted and you must rebuild Spotlight Index. For that, you can either follow the manual steps below or you can use third-party tools (mentioned one of the best tools in the second section)

To do so, let’s follow the steps:

First, make sure that  mds and mdworker are the culprits

1.  Checking Activity Monitor

• Go to Applications and launch Activity Monitor.
• Click on the CPU column to check CPU cycles used by your Mac.
• If mdworker and mds are at the top of the list, it means Spotlight has run into indexing problems.

Now, you can fix this by rebuilding Spotlight’s index.

2.  Rebuilding Spotlight’s database in Terminal

• Go to Application, launch Utilities, and go to Terminal.
• Type “Return:sudo mdutil –E/” string.

This command will help in re-indexing the Mac.

3.  Steps to take if mdworker quits

If throughout the process, you receive an error message that mdworker quit unexpectedly…it is happening because Spotlight tried to index more than its handling power.

To fix this, try to exclude external drives (if connected) and check if this helps.

• Click on Apple and launch “System Preferences.”
• Now, select Spotlight and then go to Privacy.
• Now, drag external files from the Finder to the Privacy.
