I am (trying) to help a friend get his recently purchased, slightly used iMac set up in his office. (See below regarding "slightly used") Running Jaguar, when we attempted to connect to his dial-up Earthlink account, we failed and got exactly the alerts and error indications identified at http://docs.info.apple.com/article.html?artnum=106575, namely an alert box: "Internet Connect could not open the communications device" and the following message in the Internet Connection Log: "Failed to open /dev.cu.modem: Device busy." (We are unable to check the third symptom, that the modem works under "pure" OS 9, because his iMac is one that no longer has an OS 9 startup folder option.) So, delighted, I download the MacOSX ModemUpdate.pkg to my computer, burned a CD, loaded it into his machine, clicked as instructed and was greeted with a message saying that I couldn't install this update because it is already included in the installed OS X. Regarding "slightly used": The computer had been returned to the store by its original purchaser for some unknown reason and my friend bought it for about $200 off the going price. Although the store guaranteed a complete system, that wasn't quite the case - at least with regard to the installed software. The OS 9 system folder had been removed along with Appleworks. We corrected that by running the Software Restore disk. Any suggestions?
