I have updated my MacBook Pro to the new developer beta and it has become extremely slow. Something as simple as opening Safari makes the fan turn on full speed. Any suggestions?

Activity Monitor shows that ‘trustd’ is using up a large amount of my CPU and it has made my Early 2011 MacBook Pro insanely slow. Spotlight doesn’t appear to be indexing anymore. Anyone have any idea about what it’s doing?

While installing High Sierra on my Early 2011 MacBook Pro, there was not an option to use the new APFS. Booting my MacBook into recovery mode gives an option to use it, but it fails. Is APFS available for MacBooks yet?
