Mac Book Pro (PowerPC NOT Intel) doesn't respond to the mouse ...

Hi, my 10 years old MacBook Pro (without Intel) doesn't respond anymore to the commands of the mouse or mouse track ... The arrow moves around but when I click none of the applications respond, can't get to System Preferences or anything else. Don't have a OS 10.4 Tiger CD to reinstall the software.


Any ideas out there on how to solve this problem? Any good advise would be greatly appreciated, thank you!

Try resetting the SMU:


How to Reset the SMU

The SMU (System Management Unit) is a microcontroller chip on the logic board that controls all power functions for your computer. If your computer is experiencing any power issue, resetting the SMU may resolve it. The SMU controls several functions, including:

  • Telling the computer when to turn on, turn off, sleep, wake, idle, and so on.
  • Handling system resets from various commands.
  • Controlling the fans.

I can't open anything on my computer so can't get any information. I bought my PowerBook G4 in 2005, before they installed Intel into them. Upgraded throughout the years to OS 10.4 (Tiger) and couldn't upgrade it anymore as didn't have enough power. I believe I got 1.2 GB HD, 500meg RAM. That's all I remember ... Is there somewhere I can get a CD Installation of Tiger? It didn't come with my computer. But even if I get a CD how will I be able to make it function if my computer doesn't respond? Very frustrating ... Somebody at Apple's Genius Bar told me I could try to install OS 10.5 (Panther?) instead, I will loose everything in my computer (don't mind at this point, also have back ups) but it's not sure it'll work either ...

You have some kind of Powerbook. MacBookPro was only Intel.


Have you tried unplugging the mouse and only using the trackpad?


How about starting in Safe Mode (hold down the shift key while booting the computer)?

Hi Klaus 1, you are right, I'm writing from a MacBook Pro and got confused, sorry. The problem I'm experiencing is with my old PowerBook G4, which my wife uses for E-mails and Internet only.


I just opened it in Safe Boot Mode, it was slow but at the end opened up, but still the problem persists ... no clickable objects react to the trackpad or mouse if I connect one. (:

Thank you for your suggestion, I tried it but didn't work ... My old PowerBook G4 laptop (PowerPC without Intel) doesn't want to respond to the clicks of the Trackpad or the Mouse. Tried on Safe boot mode, but still can't make it work. Even if I get a CD with OS 10.4 Tiger, I would not be able to give the CD any instructions. Tried to get to System Preferences or Disk Utility through some Keyboard Shortcuts but without success as of now. Any other ideas?


Thank you for your help!
