I have a G4 that came with OS 9 and recently loaded OS X, but now none of the programs seem to be recognized. Can't print, use DVD player etc. Can anyone help me?

Building on points from and , here is a focused, practical troubleshooting checklist and safe repair path that was not yet laid out in the replies. These steps concentrate on verifying that the Mac recognizes the hardware and that the Mac OS X installation contains the system apps and drivers it needs.

  • Verify the OS X install shipped with its bundled utilities. Inspect the /Applications folder for the system DVD/player app and printer utilities.
  • Use System Profiler (Applications -> Utilities) to confirm the optical drive and the printer interface (USB/serial/parallel) are being detected by the hardware layer.
  • Boot from the Mac OS X install CD and run the included utilities: run Disk Utility (verify/repair the volume and permissions) and, if available, use the non-destructive "Archive & Install" option to restore missing system apps without erasing user data.
  • Run Apple Hardware Test from the install media to check the optical drive and other components if install CDs include it.
  • Install vendor-supplied OS X printer drivers (from the printer maker) rather than older OS 9 drivers; many printing problems come from missing or incompatible drivers.
  • Reset PRAM (hold Command+Option+P+R at startup) if devices do not appear after the other checks.
  • Make a full backup before any reinstall or repair attempt (FireWire Target Disk Mode or an external drive works well).

Notes: archive/install will preserve user files in most cases, but a verified backup is essential. If the optical drive is not detected by System Profiler or fails hardware tests, try cleaning the drive and testing with multiple discs before considering replacement. If bundled apps are missing after reinstall, perform the installer again and choose the applications/components explicitly.

OS X is wildly different than OS 9 and most old programs won't run natively in OS X. If your OS 9 is version 9.1 or higher you can run most older programs in "Classic" mode which is an emulation of OS 9. You can download the 9.2.2 upgrade from Apple's website... But I'm not sure how you can install them if you can't log into 9.0. Perhaps someone else will have this information?

If that doesn't addres your problem at all... we'll try again :)

As noted above, what version of OS 9 and what version of OS X, as well as which "programs" (Mac OS 9 or OS X) you're trying to use that won't work.

I have 9.1 loaded but trying to load 10.0.3

I would highly suggest getting a newer version of OS X. That is the public beta of OS X from 2000. It's quite out of date, no longer supported, full of bugs, and you won't find any software that works on it.

You're significantly better off with Jaguar (10.2) or Panther (10.3). Jaguar should be quite cheap now, and Panther will be much cheaper after late March 2005 (when Tiger (10.4) comes out).
