Ap­ple has made public beta ver­sions of this year’s sys­tem up­grades avail­able for you to try. Why would you want to run a ver­sion that’s likely to con­tain a few bugs? Aside from be­ing help­ful to Ap­ple, you might want to check whether any of the apps or ac­ces­sories you de­pend upon have any show­stop­ping in­com­pat­i­bil­i­ties. It’s wise to do that as early as pos­si­ble if you plan to buy a new de­vice that’ll come with one of th­ese sys­tems pre­in­stalled.

The method of try­ing out High Sierra we present on th­ese two pages makes it easy to switch back and forth be­tween it and your work­ing sys­tem.

Things are more in­volved on iOS in par­tic­u­lar, mostly due to the time it takes to down­load the lat­est non-beta ver­sion, erase your de­vice to in­stall it, and re­store a backup.

The key thing to re­mem­ber to do on macOS and iOS is to make a full backup of your de­vice im­me­di­ately before in­stalling. Back­ups made on iOS 11 will be worth­less to you if you later roll back to iOS 10. And on macOS, Ap­ple’s ad­vised method is to back up us­ing Time Ma­chine. How­ever, restor­ing your en­tire Mac from Time Ma­chine’s back­ups is a dis­rup­tive and slow process, so we rec­om­mend an­other route that re­quires a sec­ond drive; it takes longer up­front, but it saves you stress if you run into a big prob­lem.

In or­der to try any (or all) of the public be­tas, start by fol­low­ing the three steps be­low to sign up for Ap­ple’s public beta pro­gram. Should you want to roll back to your non-beta sys­tem, see Ap­ple’s guides at
