Well, a couple of years ago I tried to replace the hard drive on my 2011 iMac. I have lots of experience modifying non-Apple computers and other DIY projects over many years. Bought the tools. Studied videos and forums and rehearsed moves. I thought all went well but the computer did not work afterward. Costly repair attempts at an authorized dealer failed. The dead iMac now sits in my shop as a sad display of 3rd or 4th quadrant risk-taking. I know many have succeeded, but I post this at the risk of derision to balance the discussion. YMMV, as they used to say.
Quadrants:
1. Know lots of a subject and very aware of one’s limits.
2. Know little of a subject and very aware of one’s limits.
3. Know lots of a subject but not aware of one’s limits.
4. Know little of a subject and not aware of one’s limits.
