How can I learn understand schematics and block diagrams for Macs and other computers (technician level please?) This is one of the questions where I expect to receive ambiguous and unclear answers. No matter how clear my question actually is. Probably because it’s in a bit of a no-man’s land. I’m working as an Apple mac technician and have some background in Electronics (mostly old anagogic related). I’d like to learn to understand and basically troubleshoot hardware issues by looking at the schematics and Block diagrams for Macs and other computers (like the ones below). I guess there has to exist some book, course or website making this approachable to a computer technician level. I’d welcome a lot some advice on this. By the way: I like watching Louis Rossman youtube videos, but I’d rather have something more formal or complete.
