Philip Houska Zowonetsera Lolemba pa msonkhano wa omanga WWDC 2016 zinatenga maola awiri, koma Apple sanathe kutchula nkhani zonse zomwe (osati kokha) zakonzekera opanga. Nthawi yomweyo, chimodzi mwazinthu zatsopano zomwe zikubwera ndizofunikira kwambiri - Apple ikufuna kusintha fayilo yakale ya HFS + ndi yankho lake, lomwe limatcha Apple File System (APFS) ndipo idzagwiritsidwa ntchito pazogulitsa zake zonse.
Poyerekeza ndi HFS +, yomwe yakhalapo mosiyanasiyana kwazaka zambiri, Apple File System yatsopano idamangidwanso kuchokera pansi ndipo makamaka imabweretsa kukhathamiritsa kwa ma SSD ndi kusungirako flash komwe kumathandizira ntchito za TRIM. Kuphatikiza apo, ipatsanso ogwiritsa ntchito ma encryption otetezedwa kwambiri (komanso mbadwa popanda kufunika kogwiritsa ntchito FileVault) kapena chitetezo chofunikira kwambiri pamafayilo a data pakagwa ngozi.
APFS imagwiranso ntchito zomwe zimatchedwa kuti mafayilo a sparse omwe ali ndi chunks zazikulu za zero byte, ndipo kusintha kwakukulu kumakhala kovuta, chifukwa pamene HFS + fayilo ya fayilo inali yovuta kwambiri, yomwe ingayambitse mavuto pa nthawi ya OS X, kapena tsopano macOS, Apple File System idzachotsa kukhudzidwa. Komabe, Apple akuti sizikhala choncho poyambira, monga momwe makina ake atsopano sangagwire ntchito pa ma disks a bootable ndi Fusion Drive.
Kupanda kutero, Apple ikuyembekeza kugwiritsa ntchito fayilo yatsopanoyi pazida zake zonse, kuchokera ku Mac Pro kupita ku Watch yaying'ono kwambiri.
Ma timestamp nawonso asintha poyerekeza ndi HFS +. APFS tsopano ili ndi nanosecond parameter, yomwe ndikusintha kowoneka bwino pamasekondi a fayilo yakale ya HFS +. Chinthu chinanso chofunikira cha AFPS ndi "Space Sharing", chomwe chimathetsa kufunikira kwa magawo okhazikika a magawo pa disk. Kumbali imodzi, azitha kusinthidwa popanda kufunikira kokonzanso, ndipo nthawi yomweyo, magawo omwewo azitha kugawana mafayilo angapo.
Thandizo la zosunga zobwezeretsera kapena zobwezeretsa pogwiritsa ntchito zithunzithunzi ndikusintha bwino mafayilo ndi maulozera kudzakhalanso chinthu chofunikira kwambiri kwa ogwiritsa ntchito.
Apple File System pano ikupezeka mu mtundu wa mapulogalamu ya macOS Sierra yomwe yangotulutsidwa kumene, koma sangathe kugwiritsidwa ntchito mokwanira kwa nthawiyo chifukwa cha kusowa kwa Time Machine, Fusion Drive kapena FileVault thandizo. Njira yogwiritsira ntchito pa boot disk ikusowanso. Zonsezi ziyenera kuthetsedwa pofika chaka chamawa, pomwe zikuwoneka kuti APFS idzaperekedwa mwalamulo kwa ogwiritsa ntchito nthawi zonse.
