mediaanalysisd=slow mac

The solution for me was keeping the Mac plugged in and on all day.

This allowed media / photoanalysis to complete the scan of photos. When you open Photos, click on the People bar and it shows you how many photos remain to be scanned. There is no off switch for it.

Also, Sierra may be encrypting files as well.

All these processes take time, incredible amounts of CPU, but they complete eventually. Took a few days for me.

Did you recently upgrade your operating system?

I think both photoanalysisd and mediaanalysisd are the scanning of all your pictures, videos for the "People" feature in Photos. Since I've upgraded, this has been eating up my cpu. It's slow but I assume it finishes at one point. You can see progress when you click the People folder in Photos.

I recently had the same file popping up sporadically after upgrading to High Sierra. After reading through this thread, I tried deleting the file but could not do so. Took it to the Genius Bar. The tech there (who really knows his stuff; he's helped me several times), said the easiest way to fix it was to do an archive/install, which he did for me while I ran errands (I love when folks at the GB know their stuff and can save me headaches/time). Since doing that, the file stopped launching. When he filled out my case notes, he said, "Ah. I see here that a few other folks have had this problem." Having worked at Apple Retail in the past, that's code for "They're aware of the issue and are working on it." Hope that helps anyone who may have this issue.

I have the same problem - my Mac goes nuts if I leave it sitting for a while. If I leave Activity Monitor open, I can see mediaanalysisd pop up after a while using 43% CPU. When I look in /System/Library/LaunchAgents/, I see no com.apple.mediaanlysisd.plist. File list jumps from mbuseragent.plist to mdmclient.agent.plist. Running High Sierra.

Hi,

Try putting com.apple.mediaanalysisd.plist in the trash, but don't empty it. Restart your Mac. This should regenerate the .plist and solve your issue. You can go back to LaunchAgents to check if you want. If all is good, either drag the old .plist onto the desktop/in a folder/wherever if you want to save it for potential future use, or empty the trash.

/System/Library/LaunchAgents/com.apple.mediaanalysisd.plist

I believe you're correct! I noticed improvement today after a couple of days since install, and leaving my computer on for the night. Thank you for the peace of mind! I got so worried my mac would perpetually be in a lagged state.

You might want to consider starting a new discussion. Since this one is marked solved, less people are likely to look at it. A new post would be much more visible. You can link to this one. Post in High Sierra.

Are you sure you are looking in the correct folder?

I tried to drag the mediaanalysisd.plist file into the trash I am getting a message saying the file can't be modified or deleted because its required by Mac os

I don't have an answer as to why it worked for EruMantis and not you. The issue would get more attention if you started a new thread.

Sure thank u

I'm sorry, but what did you mean when you said "archive/install"? I'm having the exact same issue since updating to High Sierra and my mac is freezing so much, I'm hoping this is the solution.

Did you read and try everything in this thread?

hello, how did you manage to put the com.apple.mediaanalysisd.plist to the trash? i tried all the solutions i could dig .. but .. thanks a lot

You should be able to just drag it into the trash. If you're not able to, I would start a new thread with your question.

There are lots of other threads. You can find the one I started at mediaanalysisd burning up CPU - High Sierra, but it has no useful answers.
