When i startup with all extensions, control panels etc on more then often and i never know when the pointer and mac freeze. A reboot fixes that problem until the next time.
However, When i startup with all extensions etc OFF ( holding shift key down at/during startup ) the problem does not occur. This makes me believe that it is really not a bad stick of RAM but some rotten corrupted in life extension.
What is the suggestion to create a set of startups that could narrow the startup extensions to help find the problem creating extension or control panel or something ?
I recall using a system to find the culprit(s) in a similar problem but that was more then a decade ago.
