Mac OS 7.6.1 est une mise à jour commerciale que vous devez acheter s'il n'était pas fourni avec votre ordinateur. À partir de la version 7.6 du logiciel Système, Apple a arrêté d'appeler son logiciel Système "Système xxx" et a commencé officiellement à utiliser le nom "Mac OS xxx". Ainsi, cette version est intitulée "Mac OS 7.6.x" plutôt que "Système 7.6.x".
Il existe deux méthodes "officielles" pour obtenir Mac OS 7.6.1 :
• Installer Mac OS 7.6, puis installer la mise à jour 7.6.1. Si votre ordinateur était livré avec le 7.6 installé, vous ne devez installer que la mise à jour. Pour obtenir des instructions sur l'installation de la mise à jour 7.6.1, consultez le chapitre suivant.
• Install Mac OS 7.6.1 à l'aide de l'installeur complet de Mac OS 7.6.1. Les versions récentes du CD Système "Mac OS 7.6" installent le 7.6.1 directement.
Ce chapitre discute de Mac OS 7.6 ; le chapitre suivant traite de la mise à jour 7.6.1. Pour éviter des problèmes, vous devriez lire ce chapitre et le suivant avant d'installer Mac OS 7.6. Toute personne qui utilise Mac OS 7.6 devrait également installer la mise à jour 7.6.1.
NOTE : N'ESSAYEZ PAS d'installer Mac OS 7.6 sur les ordinateurs suivants: PowerMac 4400, 5500, 6500, 7300, 8600/200, 9600/200, 9600/200 MP ou 9600/233. Ces ordinateur fonctionnent avec l'installeur 7.6.1 complet, mais PAS avec Mac OS 7.6. Afin de pouvoir installer le 7.6.1 sur ces ordinateurs, vous devez installer disposer de l'installeur complet du 7.6.1 (par exemple, un qui ne ne nécessite pas d'installer le 7.6 puis la mise à jour 7.6.1). Ce CD pouvait être auparavant obtenu à travers le programme Mac OS Up-To-Date, mais ce n'est plus le cas.
Mac OS 7.6 détruit automatiquement les fichiers suivants à moins que vous en ayez renommé certains, auquel cas vous devrez les détruire manuellement. Les bénéfices apportés par ces fichiers ont été directement intégrés au fichier System, ou les problèmes nécessitant leur présence ont été corrigés :
7.5.5 SCSI Server Update
Assistant Toolbox
PowerPC Interrupt Extension
Mac OS 7.6 comprend les nouvelles fonctions et améliorations suivantes:
• Nouvel installeur du Logiciel Système qui vous guide à travers la procédure d'installation non seulement pour la partie principale du logiciel Système, mais également pour les éléments additionels comme QuickDraw 3D.
• Gestionnaire d'extension amélioré comportant de nouvelles fonctions ;
• Amélioration des fonctions de copie d'écran , permettant des copies partielles de l'écran et des copies personnalisées.
• Open Transport est nécessaire. L'application "Options de réseau" ne vous permet plus de sélectionner "Ressources classiques de réseau."
• Gestion améliorée de la mémoire virtuelle.
• Meilleur gestion du cache pour le File Manager.
• Meilleur gestion des ressources PowerPC.
• Amélioration du "file mapping" lorsque la mémoire virtuelle est activée.
• Corrige des problèmes avec les boutons de volume sur les ordinateurs 52xx/53xx/62xx/63xx et 63x.
• Support des cartes Multiprocesseurs.
• Améliorations de WorldScript Power Adapter.
• Support des disques de taille supérieure à 4 GB sur les Power Macs et Macs 68040.
• Corrige des problèmes de gestion de la mémoire, par lequel le système prenait parfois de la mémoire sur une application (problème présent sous Logiciel Système 7.5.3 et 7.5.5..
• Gestion des volumes de grande taille (volumes jusqu'à deux tera-octets pour les ordinateurs PPC ou 680x0) ;
• Meilleure gestion de la mémoire - vous devriez rencontrer moins d'erreur de "mémoire insuffisante" avec le Finder ;
• Le cache disque est sauvegardé plus souvent, réduisant les probabilités qu'un gel ou crash efface des données ou corrompt votre disque dur.
• Meilleure gestion des ressources (meilleur prise en main des ressources système et application) ;
• Temps de démarrage plus court
• Réduction du total de mémoire occupée par la mémoire virtuelle elle-même ;
• Meilleures performances lors de l'utilisation d'OpenDoc.
• Le Gestionnaire moderne de mémoire est désormais automatiquement activé. Auparavant, vous pouviez l'activer ou le désactiver (voir le chapitre "Gestionnaire moderne de la mémoire"). Qu'il s'agisse d'un bien ou d'un mal demeure un autre débat…
• La taille de disque cache minimale dans le tableau de bord Mémoire est désormais fixée à 96 Ko.
• Elle inclut également tous les correctifs et améliorations de perfomances inclus dans le Système 7.5.5 (voir le chapitre "Informations sur le système 7.5.5").
NOTES :
• Some Performa or Power Macintosh 5200 series, 5300 series, 6200 series and 6300 series computers have a hardware problem which will not allow Mac OS 7.6 to be installed. This hardware problem is covered under the Apple repair extension program. Before attempting to install 7.6 on these computers, use the 5xxx/6xxx Tester utility in the "Utilities" folder of the installation CD.
• In order to install OS 7.6 over a network, you must have AppleShare Workstation software version 3.6.4 installed first. You can find this software in the "Utilities" folder on the 7.6 installation CD.
• In order to install 7.6 (or the 7.6.1 Update) on a Mac with a DayStar Digital 040 card installed, you will need to remove the card, install the System software, then reinstall the card.
• When installing OS 7.6, you will be asked by the installer if you would like to update the disk driver. If you choose not to update the driver, and your hard drive was formatted with Apple HD SC Setup 7.1.2 or older and never updated with a newer driver, all the files on the drive may disappear and the disk may not be able to start up your computer. NOTE : this is only applicable to drives formatted by Apple's utilities. If your hard drive was formatted using a third-party driver, you can ignore this warning and the "update drivers" step in the installation process.
• 7.6 cannot be installed over System 6. You must either install some version of System 7 or 7.5, or you must do a "clean" install.
• 7.6 can only be installed on machines which are "32-bit clean." This means that the computer's hardware supports 32-bit addressing. Using software to provide 32-bit addressing support (Connectix's "Mode32") does not suffice. In addition, computers upgraded with a 68030 or 68040 processor upgrade card are not supported by Mac OS 7.6. For information on which computers are compatible, see the "System Versions" chapter.
• The installer will automatically check your virtual memory settings. On a 680x0 Mac with 16 Mo of RAM or more, you settings will remain as they were before installation. On a PowerMac with 16 Mo of RAM or more, virtual memory will be turned on and set to 1 + the amount of RAM you have. If you have less than 16 Mo on any Mac, virtual memory will be turned on and set to 16 Mo.
• OS 7.6 installs Open Transport v1.1.1. However, Open Transport 1.1.2 was released before 7.6. If you have already installed Open Transport 1.1.2, and do not do a "clean" install of OS 7.6, you will get the following error message: "The file 'File Name' already on 'Hard Disk Name' is more recent than what you are about to install. Click Continue to replace 'File Name' with the older version. Click Cancel to leave the disk 'Hard Disk Name' untouched." You should select "Continue" and then reinstall OT 1.1.2 after the installation of 7.6 is complete.
• The latest version of QuickDraw 3D at the time of OS 7.6's release was 1.5. However, the installer for 7.6 installs 1.0.6. You will need to reinstall 1.5.
• If you perform a "universal" install, which will start up any computer that is compatible with OS 7.6, the following files will not be installed:
° Password Security tableau de bord
° ATI 3D Accelerator, ATI MPEG Accelerator, ATI YUV Accelerator, and ATI 6500 Graphics
Extension
° ATI Graphics Accelerator 1.2.2 (ATI Graphics Accelerator 1.1.4 is installed in the universal
System Folder)
° Infrared tableau de bord, IrDALib, and IRLanScannerPPC
° CDStrip control strip module
° TV/FM 1.5.3 software
INSTALLATION :
1) If you are using MacTCP, write down all of your current settings for later entry into OT/PPP. If you are using OT/PPP and are performing a "clean" install, you should "export" your settings to be imported later.
2) If you are installing on a PowerBook, make sure the PowerBook is plugged in and set to "never sleep." NOTE : you cannot install System software onto a PowerBook in SCSI disk mode.
3) Start up your Mac using the Mac OS 7.6 CD-ROM or the "Install Me First" floppy.
4) Run the "Install Mac™ OS" program on the CD and follow all of the steps (see the note about updating drivers above).
5) Choose which software you would like the installer to install. You can get info on each software package, to decide if you want it, by clicking the buttons on the right-hand side of the installer box. NOTE : if you would like to do a "custom" install, click on the "Customize" button. If you would like to do a "clean" install, click on the "Options..." button.
6) Install the software.
Troubleshooting suggestions
• If you get a message from the installer that your hard drive has problems and cannot be repaired, quit the installer, turn File Sharing "off," then try again. Often this will eliminate the problem.
• Installation problems can often be solved by starting up the computer with only the System 7.5.x extensions enabled. Extensions Manager, along with many third-party startup file managers, has a built-in "7.5.x-only" set. If there are any third-party extensions you need, such as drivers for a graphics card or non-Apple CD-ROM drive, you should also keep those active.
The following are known problems with Mac OS 7.6:
• If you choose the "Mac OS 7.6" sets in Extensions Manager (both the "Base" and "All" options), the various Nubus Ethernet card drivers will be disabled, due to a spelling mistake in the "package" field. If you are using one of these cards, this bug will prevent your Ethernet card from functioning properly. You should manually enable the appropriate file from within Extensions Manager.
• You must select a printer driver in the Chooser even if you don't have a printer connected; problems which can occur if you do not have a printer selected include phantom system folders, phantom print monitor documents, and possible problems opening the System Folder.
• If ARA Client 2.1 is installed after over the Open Transport/PPP installation included with Mac OS 7.6, it will replace the Open Transport/PPP Modem Files, which can cause connection problems for Open Transport/PPP. You should install ARA before installing OT/PPP.
• The Apple CD-ROM software no longer supports non-Apple CD-ROM drives.
• PowerTalk is no longer supported by the System software, and is in fact incompatible.
• OS 7.6 mistakenly installs the Video Startup extension and the Apple Video Player on the Macintosh TV. You should remove these files from the Mac TV to avoid problems.
• "Classic Networking" is no longer supported by the System software.
• Any applications which use the CFM 68K Runtime Enabler (see entry in the "Extensions" section) will not be installed by the 7.6 installer. This is because at the time 7.6 was released, the version of CFM 68K Runtime Enabler which was available was problematic. Thus Apple decided to not include it in the System install. You can, however, download the newer version of the file from Apple and then install any application that needs it (OpenDoc, Cyberdog, LaserWriter 8.4, Apple Telecom 3.0) later.
• Related to the above item, if you have a 68040 Mac upgraded to PowerPC, you will not be able to use the LaserWriter 8.4 software when in the non-PowerPC mode. You will have to install LaserWriter 8.3.4 instead.
• OS 7.6 will install AppleVision software version 1.0.4 on 68040 Macs and Nubus PowerMacs. However, this version is not fully compatible with these computers. If you are using an AppleVision monitor on one of these systems, after installing 7.6 you should reinstall your AppleVision software from the original disks that came with your monitor.
• On PowerBook 190 and 5300 systems (and possibly on other PowerBooks with passive- matrix displays), the first time you startup/restart after installing OS 7.6 (and the first time you restart if you ever reset the PRAM) the screen may appear blank. The reason for this is that the PowerBook is resetting the power manager. You should restart once again and the problem will go away. You can do this by holding down the power button (upper right-hand corner of the keyboard) and then pressing return (which will shut the computer down) and then pressing the power button again to startup. You can also press the power button and then press the "r" key to restart. The display should return to normal, or allow you to use the brightness and contrast controls to return it to normal.
• If you use QuickDraw GX, you will not be able to print directly from Cyberdog.
• The 7.6 installer may automatically turn virtual memory on. This will prevent RAM Doubler from loading. If you are using RAM Doubler, be sure to turn virtual memory off in the Memory tableau de bord.
• The Apple Color One Scanner extension 4.1 will not work under OS 7.6 with virtual memory turned on.
• On the Mac LC 575 and use the "Monitors & Sound" tableau de bord (via the AppleVision software or a "universal" system install), the volume buttons on the front of the computer will not register in the tableau de bord.
• On PowerMac 5500 and 6500 models, if external speakers are connected at startup, and later disconnected, the internal speakers will remain muted. The only workaround is to restart the computer after disconnecting the external speakers.
• The 3DMF Viewer will not work with QuickDraw 3D 1.5 or later, presenting an "insufficient memory" error. The only solution is to install an older version of QuickDraw 3D.
• Part 1 of the Macintosh Tutorial installed by OS 7.6 will not work on 68030 or 68040 Macs.
• OS 7.6 does not install PC Compatibility software or Apple Telecom software. If you do a "clean" install, you will have to reinstall this software if you need it.
• The Macintosh Easy Open tableau de bord has been renamed "Mac OS Easy Open" to reflect the fact that clone computers are running the Mac OS but are not actually Macintosh computers. Some software installers will install a copy of the older Macintosh Easy Open. You should remove this file.
• Along those same lines, the Macintosh Guide Apple Guide module has been renamed "Mac OS Guide."
• If you use the Network Software Installer v1.5.1, it will install an earlier version of AppleTalk than is included in OS 7.6, preventing Open Transport from functioning.
• If you install the QuickTake 150 software, it will install an older version of the QuickTime PowerPlug extension. Before using the QuickTake 150 installer, move the QuickTime PowerPlug extension out of the Extensions folder. After installation, move the file back to the Extensions folder, replacing the version just installed.
• Sometimes AppleTalk will not release the serial port when switching from a LocalTalk printer to a serial printer. If this happens to you, you will have to restart.
• Installing or removing QuickDraw GX when Adobe Acrobat is installed will cause "missing font" error messages. You must reinstall Acrobat to fix this problem.
• If you own a Quadra upgraded with a PowerPC Upgrade Card, you cannot use the Drive Setup utility intended for PowerPC computers. You will have to use the HD SC Setup utility. However, in order to use this utility, you must restart in 68040 (non-PowerPC) mode.
• Once a drive has been initialized with Drive Setup, you should not use the HD SC Setup utility.
• After installing OS 7.6, your settings for Apple Menu Options, General Controls, Views, and the "Empty Trash" warning will be reset to the default values. You will need to manually set your preferences again.
• Extensions Manager does not support aliases. You will not be able to enable/ disable aliases to files.
• The Assistant Toolbox extension (actually intended for PowerBooks) is supposed to provide the ability to save the contents of a RAM disk at shutdown. However, if the extension is used on a desktop computer, it will not save these contents.
• The Apple System Profiler utility will often provide incorrect information on non-SCSI devices.
• If you use the debugging tool MacsBug, you will need to update to version 6.5.4. All earlier versions are incompatible with OS 7.6.
• The version of the OpenDoc ODFLibrary which is installed by OS 7.6 is older than the version required by many newer OpenDoc applications and the newest OpenDoc part editors. In order to install a newer version, you must first remove the version installed by OS 7.6, then use the installer for one of these newer applications to install the newer version.
• Users who had an "upgraded" trackpad installed on a PowerBook Duo 2300c or PowerBook 190 may experience a conflict between Mac OS 7.6 and the new trackpad. The computer may crash after coming out of sleep when the trackpad button is pressed. This problem only happens with Mac OS 7.6 and non-factory-installed trackpad mechanisms. This problem is fixed in Mac OS 7.6.1.
The PowerBook 3400 System software CD cannot be used to install Mac OS 7.6 on a desktop machine. It contains specific software for the 3400, and is lacking specific software needed by desktop computers. Conversely, you cannot install OS 7.6 on a 3400 using the System CD that came with a desktop Mac, or the general release version of 7.6 that you would purchase in a retail store.
When you install the 3400-specific version of Mac OS 7.6, the System file itself will claim to be version 7.5.3. This is normal. In the 3400 version of 7.6, the PowerBook 3400 Enabler file actually contains the updated code for OS 7.6. NOTE : this is only true with OS 7.6; when you update to 7.6.1, the System Enabler is no longer needed, and the System file will correctly identify itself as "7.6.1."
The version of Open Transport that is installed by OS 7.6 is version 1.1.1. However, users can download Open Transport 1.1.2 and install it. However, Open Transport 1.1.2 is not supported by Apple on the PowerBook 3400. In fact, the only way to use Open Transport 1.1.2 on a 3400 it is to install it and then immediately reinstall the 7.6.1 update (see the next chapter).
When using the internal modem on a 3400, or when the 3400 is waiting for a fax call, the left-hand speaker will be muted somewhat. This is because the left speaker is connected to the modem for audible feedback during modem use. You can change the balance in the Monitors & Sound tableau de bord to even out the sound when the modem is in use.
