Upgrade Success- Late 2015 27” 5K iMac (iMac17,1)

Just upgraded my father’s Late 2015 27” 5K iMac (iMac17,1) to Sonoma 14.7.1 via OCLP 2.1.2 with zero issues. Everything worked exactly per the instructions. I did disable power management “autopoweroff”, “standby” (not sleep), and “proximitywake” features via pmset as a proactive measure, since I’ve read about possible sleep/wake issues. Much to my surprise, Sonoma runs noticeably faster on this Mac than Monterey did. I’m thrilled that he’s able to keep using this well-equipped Mac and receive security updates again. For those curious, it’s the fully loaded model, 4.0 GHz Quad-Core Core i7, 32 GB RAM, 1 TB SSD, and Radeon R9 M395X.
