Install if You're Testing macOS Mojave for Work
Are you an IT manager? Or are you at least the go to tech person in your company or section of the office? If so you may want to install the macOS Mojave beta on a spare computer to make sure it works with the apps and processes that you use.
This will be a bigger issue closer to the release, and it's especially important if users supply their own computers and are able to upgrade without running it past IT first.
In addition to software, you can use this to check with specialized hardware like printers and accessories so that you can contact the manufacturer if you need them to work on a fix.
