Thankfully, this is only a temporary problem. Spotlight needs to build an accurate index of the files on your Mac so that search results are fast and correct. (Adding a drive to Spotlight’s Privacy tab prevents it from indexing the volume.)

The indexing process can really slow things down after an upgrade since the startup drive had a lot of information changed on it. One of the perennial performance hits that occurs after a Mac operating system upgrade is Spotlight indexing the startup drive, or for that matter, any new drive(s) you may have added recently. If you’re experiencing speed issues after installing macOS High Sierra, give these tips a try. Luckily, such problems are usually temporary or easy to fix. In most cases, performance remains about the same, with any efficiencies in the new OS offset by new features that take more than their fair share of your Mac’s resources.īut sometimes after installing a new OS, your Mac may seem to have had its performance rug pulled out from under it.

Most of the time, upgrading to a new version of the Mac operating system doesn’t bring performance increases. You just upgraded to macOS High Sierra and you’re amazed at the overall performance improvement you’re experiencing on your Mac.
