    Can't seem to find anyone with the same issue by searching. Anyone have the process "xpcproxy" take up over 100% CPU after installing Sierra? It didn't seem to start at first, but suddenly started sometime after. This is on a 2010 MacBook Pro 15" with an SSD. The same process seems to be sitting at around 200-400 MB of RAM but holding steady and not climbing. Can't tell if this is some sort of normal indexing type process or not since I've found no matches for similar cases.

    EDIT: I just clicked on the battery icon in the menu bar and it's saying that "Photos Agent" is taking up significant battery. I'm guessing xpcproxy has to do with Photos then. Guess I'll just continue to let it do its thing for a while.

    EDIT 2: Found out that only iStat Menu is calling the process xpcproxy. Activity Monitor calls it photoanalysisd, which the name alone kinda gives it away, but also a search reveals other people have encountered too. I'd just delete this post, but I can't see to find a way to do that, so I guess here it is for posterity.

    Absolutely same problem here. on a 2010 Macbook Air that gets hot anyway, its shooting up to 80-90C with fan on full while Photos Agent does its work. i think it's doing something with your Photos/iPhoto library to reflect the upgrades, so the larger your photo library, the longer it will take.

    Yeah, I opened photos and then the "People" album and saw that was the culprit. It showed a progress of amount of photos scanned and amount left and that it would only scan when not using the app and plugged into power. The weird thing though is that this isn't my main computer and I have iCloud photo library turned on between this MBP, my iMac, and my iPhone. Wouldn't you think they could share the data instead of having to work for it themselves? It's kinda confusing. Opened Photos on my iMac and everything was already analyzed and sorted.
