Dans cet article je pr\u00e9sente la m\u00e9thode pour faire tourner Mac OS 9 sur un mac mini avec processeur PowerPC G4<\/p>\n\n\n\n

Lors de leur sortie en 2005, les macs mini n’avaient pas la possibilit\u00e9 de d\u00e9marrer Mac OS 9, ils pouvaient n\u00e9anmoins encore faire tourner les applications \u00e9crite avant Mac OS X gr\u00e2ce \u00e0 l’environnement classic.<\/p>\n\n\n\n\n\n\n\n

Des passionn\u00e9s ont r\u00e9ussi \u00e0 patcher la ROM Mac OS afin que celle d\u00e9marre sous mac mini, vous pouvez r\u00e9cup\u00e9rer l’image disque ici : https:\/\/macintoshgarden.org\/apps\/mac-mini-g4-macos-92-v9<\/a> (prenez le premier t\u00e9l\u00e9chargement : Mac_Mini_G4_OS9.zip (462.27 MB<\/em>)<\/small>)<\/p>\n\n\n\n

J’ai du acheter une souris Apple d’occasion, les souris avec et sans fil que je poss\u00e9dais n’\u00e9tait jamais reconnu par Mac OS 9, ce qui emp\u00eache l’installation du syst\u00e8me.<\/p>\n\n\n\n

\n

Plut\u00f4t que de graver un CD, j’ai fabriqu\u00e9 une cl\u00e9 USB bootable en utilisant l’outil syst\u00e8me disque sous Ubuntu.<\/p>\n\n\n\n

\"\"<\/figure>\n<\/div>\n\n\n\n
\n

On fait \u00ab\u00a0Restaurer l’image disque\u00a0\u00bb<\/p>\n\n\n\n

\"\"<\/figure>\n<\/div>\n\n\n\n

On choisis le fichier image de Mac OS 9 pour mac mini G4 : \u00ab\u00a0Ross_s Mac mini OS 9 CD v9.iso\u00a0\u00bb et on d\u00e9marre la restauration :<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Une fois que c’est fait on obtient notre Mac OS 9 sur USB pr\u00eat \u00e0 \u00eatre installer.<\/p>\n\n\n\n

Pour installer Mac OS 9.2.2 :<\/p>\n\n\n\n

    \n
  • \u00c9teignez le mac<\/li>\n<\/ul>\n\n\n\n
      \n
    • Placez la cl\u00e9 USB dans le port juste \u00e0 cot\u00e9 du port Firewire, vous pourrez faire autrement mais la requ\u00eate suivante sera \u00e0 modifier si vous utilisez un autre port.<\/li>\n\n\n\n
    • Allumez le mac et attendez le bruit du carillon de d\u00e9marrage<\/li>\n\n\n\n
    • Quand le son est termin\u00e9 appuyer, et maintenez, les touches command\/pomme (suivant le clavier) + alt\/option (suivant le clavier) +O + F (qui signifie \u00ab\u00a0Open Firmware\u00a0\u00bb)<\/li>\n<\/ul>\n\n\n\n

      L’\u00e9cran open Firmware va d\u00e9marrer et vous entrez la requ\u00eate suivante :<\/p>\n\n\n\n

      boot usb0\/disk@1:,\\\\:tbxi<\/pre>\n\n\n\n
      \n
      \"\"<\/figure>\n\n\n\n
      Lancez la commande avec la touche \u00ab\u00a0entrer\u00a0\u00bb et le mac va d\u00e9marrer<\/p>\n<\/div>\n\n\n\n
      \"\"<\/figure>\n\n\n\n
      \n
      Initialiser le disque dur sur lequel vous souhaitez installer Mac OS avec l’outils \u00ab\u00a0Drive Setup\u00a0\u00bb qui s’ouvre au d\u00e9marrage :deux partition \u00ab\u00a0Mac Os Extended\u00a0\u00bb, la premi\u00e8re qui sera r\u00e9serv\u00e9 \u00e0 Mac OS 9 et la seconde pour Mac OS X. <\/p>\n\n\n\n
      \"\"<\/figure>\n<\/div>\n\n\n\n
      J’ai eu des soucis en mettant Mac OS 10.5 en premi\u00e8re partition : je ne pouvais plus d\u00e9marrer Mac OS 9 (au d\u00e9marrage il n’\u00e9tait jamais affich\u00e9 dans les choix).<\/p>\n\n\n\n
      Une autre configuration que j’ai test\u00e9 est de mettre Mac OS 10.4 et Mac OS 9 sur la m\u00eame partition mais, la encore, Mac OS 9 n’est plus propos\u00e9 au d\u00e9marrage.<\/p>\n\n\n\n
      \n
      Une fois le partitionnement effectu\u00e9, lancez l’outils \u00ab\u00a0Apple Software Restore\u00a0\u00bb disponible sur la cl\u00e9 usb<\/p>\n\n\n\n
      \"\"<\/figure>\n<\/div>\n\n\n\n
      \n
      Choisissez la premi\u00e8re partition et faite \u00ab\u00a0Restore\u00a0\u00bb pour lancez l’installation<\/p>\n\n\n\n
      \"\"<\/figure>\n<\/div>\n\n\n\n
      Suite au red\u00e9marrage Mac OS 9.2.2 est op\u00e9rationnel !<\/p>\n\n\n\n
