So I was just using my computer normally when I was suddenly having an issue where I could not click on anything. I was forced to hard restart but it did not help. I am still able to navigate with the trackpad or my mighty mouse (wireless) but clicking with either does nothing. After some searching I have reset the pram multiple times and have also done command+S at boot and run fsck. Resetting the pram worked once, but only for maybe 5 minutes. During that time I ran a permissions test, it corrected 2-3 things but that is it. I have tried booting from the leopard cd but it spits the cd out. I am pretty much out of ideas. To recap: Macbook core duo 2.0 (Original macbook release) running Leopard, all updates applied Trackpad and external mouse work for navigating, but not clicking. Desktop seems completely unresponsive, hovering over dock does not magnify it as it should. Worked temporarily once or twice after resetting pram. Have run fsck multiple times. No issues found. Removed battery for 10 minutes and pushed the power button toe reset the SMU Relaunching finder does not solve issue. Using a wired mouse works partially Attempting to boot from disc ends with the disc being ejected. Have tried two leopard discs and a Disk Warrior disc. Let's see who saves the day for me. thanks!
