I have run Developer betas of the next Mac operating system for years on external, dedicated drives for that purpose. It really is helpful to experience the next macOS when writing a Mac blog. However, I have always discouraged people from installing any type of beta on their main computer. It is just too risky. In this article, Dr. Mac reiterates a yearly theme of ‘do not install betas on a main workflow machine’. There is just too much potential for grief.
