Re: unable to upgrade to system leopard on my eMac

I don't know that you necessarily have to get rid of your computer. I have a G4 circa 2000 with 400 MHz processor. I run Tiger OS 10.4.1 and can run Illustrator CS on my machine. 
It is not running at lightspeed mind you but it still works fine. 
There may be some interim updates that you need before going to leopard... I would try talking to someone at an apple store or call tech support about it. Apple is really good about customer service.  
Your eMac has to be "younger" than my tower G4 Gigabit Ethernet model so don't give up too soon. I don't think CS3 will use like 50% more resources compared to CS so your computer should be able to handle it. 
Good luck,

Re: unable to upgrade to system leopard on my eMac

With software and computers changing constantly-I use older software for older macs. You will continuously run into problems dealing with new software and old computers. See if you can find older versions that still run great rather than the creative suite. Stick with earlier system software as well. Now days 640 for memory is not much because of the increase in software space use. You can also allocate memory to certain software you use most.

Running Leopard on a box that old is not really the optimum thing to do. It's got 64 bit architecture and being a G4 is 32 bit, your box will not take advantage of the speed increase. As a matter of fact, and this is from experience... your machine will slow to a crawl. I wouldn't stick an OS newer than Panther on a box that old. Even Tiger slowed it down to ungodly proportions.

My emac will start up and show a ? marm help me

The ? with a folder means it can find a bootable system file / drive.

Do you have a copy of your Operating System install disc still or a copy of Leopard or Snow Leopard around?

You'll need to boot to the cd (hold down the C key when you power on the system)

From there you can access Disk Utility and attempt to repair the drive.

Let me know what you're working with and I'll help you out the best I can.

I bought a eMac from the dep of Education and I am unable to get into it because i don't have the username or password

You should format the internal hard disk and install a clean and fresh version of Mac-OS anyways and create a new user-account. If there is no install-disc included, try calling Apple, tell them your eMac's serial number (All eMac's have their serial numbers printed inside the disc drive door), and ask them if they have any replacement install discs for your model of eMac. Check out the Apple eMac support page or the Apple eMac support forum for more informations.

You may want to upgrade your OS to a newer system. You can also update Quicktime and that may make a difference as well.
If you're running 10.3, you may want to move up to .4.

Downloading Adobe Flash

It seems that more and more programs are cutting support for Panther (OS X 10.3). I would try to download Firefox and see if the website works. Firefox 3 isn't compatible with Panther, so you need to get Firefox 2 at:

Select your favorite language and click the middle column for OS X. After you install Firefox, see if the website works. Hopefully Firefox will acquire the version of Flash that it needs.

If not, let me know. I'll monitor this thread.

Network a G4 (OS 9) to a eMac (OS X)

OK - first, crossover cables let you network PCs together without a switch or router. I would strongly recommend returning the crossover cable and buying a router so that you can use both computers on the internet at the same time.

Second, the eMac monitor can not directly be used as a monitor for your G4 - it's not built that way. However, you can use Screen Sharing on OS X (if both have Leopard) or Apple Remote Desktop software (if you buy it) to remote control the G4 using the eMac.

You will DEFINITELY need a monitor on the G4 in order to set it up at all, so I hope you have that.

Keep in mind that you can buy, for less than $200, an LCD screen that is larger and better quality than the eMac, and it would leave the eMac useful as a second computer. Since the eMac is unlikely to work at all with Leopard, and you'd have to buy Apple Remote Desktop, you're going to spend less money by buying a separate screen for the G4.

Leopard won't install

Found this on the net:

Those upgrade cards always have given me a problem with migrating to Leopard. If you can upgrade to a used G5 or even Intel basd mac you might be more happier with less hassle.
