Thank you SO much, and I¡¯m happy it turned out well. The grounding strap is something I¡¯ve wondered about, because I¡¯ve watched a bunch of OWC and iFixIt and other independent videos, and none of the people doing the disassembly/reassembly seem to be wearing them. Back in the days of the cute little box 128 K Mac, there could have been several thousand volts on the back end of the CRT for people who ventured inside, and there was no space to do what we could without being quite close to that gun. My understanding is that the threat to US is when working around the power supply, but the threat to the iMac itself is always there.
You're welcome Jim. When working on equipment where there are programs stored is where you need to make sure you don't have a static build up on your body. It only takes a few volts to scramble a program. Better safe than sorry.?
