It’s fascinating to learn how Apple developed specialized tools for service providers to replace parts or fix issues in early Macs. I’ve never opened up a Mac, iPhone, iPad, or Apple Watch, but I’ve spent the past eleven years researching various Apple topics, including troubleshooting. The only exception to wearing ESD straps is dealing with CRTs, which the biggest part is that you have to follow strict safety precautions and the instructions provided. The video I sent you earlier shows a technician repairing and caring for a Macintosh color classic, a CRT Mac that was popular in the 90s. The technician didn’t have the discharge tools you mentioned in the video, as LCDs, less bulky OLEDs, and now Liquid Retina displays have become more common. That tool became depreciated later on. Instead, that guy had to use the traditional alligator clip and screwdriver method, which is considered a last resort in this manual. Did you get a chance to watch the video I sent tho?
