Mac freezes/unresponsive - a process called mediaanalysisd

Since i could not delete com.apple.mediaanalysisd.plist , i solved this problem by repairing photos albums.

1. Exit Photos App - If it is open
2. Hold down the Option and Command keys and then open Photos App (keep holding the keys)
3. Let go of the keys - In the dialog that appears, click Repair to start the repair process.
4. Once done, exit Photos
5. Leave your Mac idle for for sometime - it will no longer freeze

UPDATED Steps - I ran into a bit of trouble again, this time with photoanalysisd

To leave no space for errors follow these steps.

Exit Photos App - If it is open

1. Hold down the Option and Command keys and then open Photos App (keep holding the keys)
2. Let go of the keys - In the dialog that appears, click Repair to start the repair process.
3. Once done, exit Photos
4. Open Photos again
5. Open one photo from each of your albums (e.g vacation 1, vacation 2)
6. Some of the photos you open *might* give an error saying "Cannot locate original" - in this case you need to choose the folder again manually
7. Done! Leave your Mac idle for for sometime - it will no longer freeze
