HAVE A MAC G4 THAT I CAN'T INSTALL LEOPARD 10.5.6. HOW DO YOU INSTALL THE OS WITHOUT IT FALLING


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.

I just install 1.5 GB in my Powermac Quicksilver G4 and now it won't power on. What's wrong?


Make sure access door is closed and latched completely & try pulling power cable for 30 sec then reattach and try restart. If those don't work - contact macsales.com (excellent Apple/Mac folks)

G4 powerbook wont start it shows folder with flashing question mark then apple symbol


Try taking out the RAM chips and re-inserting firmly. Nothing? Try re-installing the operating system. Nothing? Try replacing the hard drive and then re-installing the operating system. Nothing? Try replacing the RAM with new higher memory RAM. Nothing? Your fu.kd and need to take the thing in for more thorough inspection by the Apple dorks.

Cant install so 10.2 onto powerbook g4.


Remove both RAM chips and re-insert, because sometimes they come loose. Now give it a shot old chap. Also, your RAM chips may have died, so insert new ones and give it a shot.

Don't install Panther 10.2, because that operating system (OS) is too old. The PowerBook runs best with the Tiger 10.4 OS. You need to install a retail version disc with black label instead of a gray label disc, because those discs are computer specific to certain models only.

No screen on start up on g4 notebook


Try reinstalling MacOS on your laptop, as far as I know, all Mac come with recovery disks. To boot of off a disk, make sure the disk is in the drive , reboot the computer, and press C while the chime is playing. You SHOULD be able to reinstall. What your describing usually happens to very old iMacs that have bad, incompatible, or no RAM installed. If none of the above works, take it to an Apple Store, they were very helpful when my iPod had a bad battery

No monitor works on my G4 Power Mac


Hi,
If no monitor works on your Mac, but the machine is booting, the only assumption I can draw from this is a faulty display card.
Try another display card and see if this helps.

I would say there is a bad ram stick in there. If you have more then one take one out then restart if nothing changes try the other.

G4 dual 1ghz not switching on


Many times if the battery on the motherboard dies, the computer won't startup at all. Try replacing the battery and push the tiny reset button on the motherboard and see if it will power on then.
