Thanks for responding to my question. I am using an iMac MacOS Monterey, Version 12.4
Imac Retina 4K , 21.5 inch 2017, Processor: 3.6 GHZ, Quad-Core Intel Core 17, Memory 16GB 2400 MHZ DDR4, Startup Disk Macintosh HD, Graphics Radeon Pro 560 4GB, Serial # D25Y14YWJ16C
FYI: I just did a new complete backup to a 5T External Drive as my new Time Machine Backup
Does this help?
Sorry for the delay in responding. I listened to both the video links you sent. It is NOT like the last one and not exactly like the first one. It is similar to the first one but slower with a pause in between the click sound. I did unplug my external drive and it was not that and the clicking sound seems to happen when the machine is not being used and sitting idle. I usually keep it in Sleep mode at the end of the day. Does this help any?
