I'm running OS 10.13.1 and I did a fresh install of High Sierra and imported my files, apps, etc via the migration assistant. I have an original Apple SSD installed.
Since installing, the available capacity in the Finder is delayed in updating and inconsistent. Updating available space can take hours, days, or require a restart.
Currently the finder says I have 127.09GB (out of 500GB) available. Disk Utility has 123.03 available. "About This Mac" shows 93.67GB available. System Information shows 79.4GB available.
Anyone else having these kinds of issues and is there a way to get available space to 1) be accurate and 2) update instantly?
