You have too much time on your handsAny time a new OS comes out you should always reformat and start fresh, it's to ensure the drivers and data are clean. II tried Mojave overlaying HS. I just finished a fresh install and it's night and day!
I do the same with Microsoft products!
a full OS load from scratch and all app reinstalled don't take more than 1-2hrs, no big deals, the potential benefits outweigh the negatives.You have too much time on your hands
I’ve gone from Snow Leopard to the present without a fresh install. Upgrading is fine.Is this for those who actually need a fresh install or is their some other benefit versus upgrading?
