Regenerate the DYLD and XPC caches on macOS
On occasions, usually after huge software updates, the shared caches are left in non-optimal state, and the system seems to be a bit sluggish. Rebuilding of the caches may resolve the problem:
sudo update_dyld_shared_cache -force sudo /usr/libexec/xpchelper --rebuild-cache
The Mac needs to be restarted afterwards.
Sometimes, indexing of the Mac’s content cause a permanently high CPU load, which may also be the cause for a slow system. In this case, it would be good the rebuilt the index as well:
sudo mdutil -E /
