I have a MAC desktop with El Capitan installed that belongs to a friend. When I first looked at it, the computer would take about 10 minutes before it would start to go to the desktop. That would take at least 5 more minutes before it loaded. If I tried to use finder, the unit would stop responding and finder would be listed as not responding. I then followed instructions to delete the finder plist file. I also went to look at the StartUpItems folder, but can not find one in the Library folder I found 3 extensions in Safari (2 maps galaxie and one unknown) and removed them. This is all of the issues I can find at this time. The unit boots into safe mode with no issues. I have run CCleaner for MAC and removed clutter. There is almost 900 GB free on the terrabyte drive. I ran the disk analyzer and it found no issues. I am stuck. One final note, the owner has no idea where she put whatever disks came with the computer, so I lose a few options there! Anyone have any suggestions?
