Nearly every time I mount an HFS+ volume on macOS High Sierra 10.13, a process called iconserviceagent reads all its files, sometimes hundreds of gigabytes. The system slows down to a crawl and the only solution is to wait or to unmount the disk.

Is this a known issue or bug or something I can configure or just fix straightaway?

  • Thank you, but this didn't help with my problem. However, Apple fixed the issue with the release of macOS 10.13.2.
