macOS High Sierra

From a new file sys­tem to pow­er­ful graph­ics im­prove­ments Ro­man Loy­ola and Michael Si­mon round up all you need to know

The next ver­sion of Ap­ple’s op­er­at­ing sys­tem for the Mac is called macOS High Sierra. While the OS is mostly about soft­ware re­fine­ments, it also lays the foun­da­tion for fu­ture in­no­va­tions in the worlds of VR (vir­tual re­al­ity) and AR (aug­mented re­al­ity).

A new file sys­tem

Ever since Sys­tem 8, the Mac has used the HFS+ file sys­tem to keep our doc­u­ments and di­rec­to­ries run­ning smoothly, but at last year’s WWDC, a new Ap­ple File Sys­tem (APFS) was an­nounced. It made it into iOS with the iOS 10.3 up­date, and with High Sierra it’s also com­ing to the Mac. But where the changes to iOS are largely be­hind the scenes, you’ll re­ally get it see it in ac­tion in the new macOS.

One of the main tenets of High Sierra, APFS will be new the new de­fault file sys­tem, bring­ing an ad­vanced 64-bit ar­chi­tec­ture and a re­spon­sive de­sign to cut down on the time it takes to do com­mon tasks. Ap­ple VP Craig Fed­erighi quickly de­moed how fast files are copied, and it should save quite a bit of time, even on older Macs. APFS also brings some heavy-duty se­cu­rity, in­clud­ing built-in en­cryp­tion, crash-safe pro­tec­tions, and sim­pli­fied data backup on the go.

Bet­ter Pho­tos

Pho­tos is rapidly be­com­ing one of the most used apps on our Macs, and in High Sierra it looks we’ll be spend­ing even more time with it. A slew of new fea­tures await us in the new OS, in­clud­ing bet­ter or­ga­ni­za­tion, looped Live Pho­tos, and new Mem­o­ries cat­e­gories. It’ll also be eas­ier to iden­tify who’s in your pho­tos with more ac­cu­rate Peo­ple iden­ti­fi­ca­tion and cross-de­vice sync­ing for al­bums.

But the coolest fea­ture may be a set of new builtin edit­ing tools. Pho­tos al­ready lets us make some awe­some ad­just­ments to our snap­shots, but High Sierra se­ri­ously ups the game with pow­er­ful pro-level
