How can I run an un­signed app in Sierra?

The sim­plest way is to se­lect the app in Finder, and use Finder’s Open com­mand to open it. The first time you do this af­ter down­load­ing the app, you’ll have to opt to open the app de­spite its miss­ing sig­na­ture, but once it has been run, full Gate­keeper checks are not re­peated.

How much free space do I need for High Sierra?

In ad­di­tion to that re­quired for a ma­jor macOS up­date, if you start up from an SSD, the in­staller will need extra free space to con­vert that to AFPS. That’s not read­ily pre­dictable, but most who up­grade will find 10GB an ab­so­lute min­i­mum, and 50GB more com­fort­able.
