Seeking astrological advice on how to upload my iCloud Photos

I spent two hours on the phone with Apple today, and their techs cannot answer the following question: What conditions need to be met for my photos in the Photos app to upload to iCloud at full speed?

I asked three senior technicians and not one was able to give me a clear answer. There is contradictory information in Apple’s support documents, but most importantly there is NO technical manual whatsoever that actually authoritatively says how it works. Nobody knows! We have to study it like a living being with experiments, because there was never a point at which one of the engineers said “let’s write down how this thing works so that our users can be informed, or at least give it to our techs.” Nope. Nobody that a consumer can access at Apple has an answer to the question “What must I do – or could I do – as a user to convince my Mac that uploading the photos I just added would be a compelling enough activity to justify risking a cooling fan being kicked on or battery charging being slightly slowed or, god forbid, a hypothetical video stream by another user of the router buffering for a moment?”

There is no answer, and infuriatingly, some of the possible answers are direct opposites. So I need to prevent the computer from sleeping, lest it go into a further power saving mode and stop uploads altogether? Or instead do I need to shut the lid so that it goes into “Power Nap” (which itself cannot be triggered manually) and completes its “background” tasks? Nobody can tell me because nobody knows. And it’s absurd to try and figure it out experimentally because I could t know, for example, if the threshold might be something like “computer must be totally idle for 27 minutes with an active wifi connection.” Should I check the computer’s horoscope? Does the phase of the moon matter? Should I kill a rodent for advice from its entrails? This is just completely absurd because somewhere there IS a human being who knows the conditions because they set them, but there is no pathway in this corporate culture between that person’s knowledge and the mind of the user of the product, who increasingly is demanded to simply accept that the black box works in a way that should be satisfactory to 80% of users 80% of the time, and if you aren’t in that 80% that’s a personal problem and not something to bother them about.

Any astrologers want to take a crack at this?

Okay,
