Troubleshooting Symptom/Cure Tables: Startup Problems Before the Finder Symptom/Cure Tables: Startup Problems Before the Finder Appears If you have trouble starting up the iMac, and the problem occurs before the Finder appears on the screen, you may have either a software or a hardware problem. Following are troubleshooting tables with problem symptoms that you may see before the Finder appears. Possible causes for each symptom can be found in the left-hand column with the corresponding fixes in the right-hand column. The troubleshooting information is presented in the order of the most probable cause and fix; therefore, Apple strongly recommends that you carry out the troubleshooting in the order in which it is presented. Note: If you are instructed to replace a module and this does not fix the problem, be sure to reinstall the original module before you proceed to the next fix.
