Ops Installed Mac OS 9.1 on too old model Mac (from 7.5)

[dejoe]

I'm trying to assist my sister, the blind leading the blind. She has a MAC that is 4 1/2 years old, I'm trying to find out the model will update when I get it.

She was running OS 7.5. She ran into problems with browsers and such and decided to upgrade to OS 9.1. What she didn't know at the time is her model Mac would not support the OS upgrade. She couldn't run any applications.

She finally called Mac Tech support, the guy explained her system model was not supported for the OS 9.1 upgrade. He had her put the 9.1 system folder in the extentions folder ( I hope I'm getting this right). Now her system will boot up as 7.5, but she can't access all her programs. Such as her address book.

I suggested there should have been an uninstall process, that perhaps some type of link was written to point to the 9.1 system and when the system folder was switched without a formal uninstall process certain files or folders were still pointing to OS 9.1 instead of 7.5.

Can anyone help? There is no system backup to revert to. Is there an uninstall feature for the OS?

Thanks,
dejoe

Assuming she did the install properly then the old system folder (equiv of the windows directory) was renamed old system folder.

Mac Tech Support will usually help you revert back to the old system folder and make that the bootable one.

Hence she nows starts back with OS 7.5.

Everything should be as it was except that the shortcuts may be invalid.

Rebuild the desktop and any shortcuts that do not work, check them manually and repoint as required - some will point to old system folder, some to nowhere in particular and some will be right.

That age would be a 7300 or a 7500 or similar. They won't even take 8.6 without losing support for some things.

Zelandakh,
Thank you for the reply. Can you give me step by step instructions as how to rebuild the shortcuts?

Thanks in advance,

If you double click on it and it does not work, bin it. Browse through the hard disk to the right place and create a new one. If you do a command I on the one that does not work it may say macintosh hd: old system folder: something when it should now be the system folder rather than the old one.
