I understand, as I too stopped using IPFW years ago in favor of PF. There’s a process named photolibraryd and it seems to have that same nasty behavior. The symptoms are identical but I can’t use IPFW because Apple removed it in OS X Yosemite. That IPFW solution worked just as well for throttling the other cloud music services.įast-forward a couple years to Mac OS 10.10.3 and the new Photos app that stores all my photos in the cloud. I blamed it on iTunes and used the built-in IPFW firewall to plumb a 256Kbps pipe so that iTunes Match uploads would stop erring out and I could use my internet connection during the long upload process. That should have made the upload process quick, except that something about the upload mechanism Apple uses caused severe network congestion and network stalls of 5 full seconds. The iTunes Match upload was far smaller because Apple has the worlds largest music library and iTunes Match only uploaded my songs that weren’t already already in their collection.

For them to stream my music back to all my devices, I first had to first upload all my music (82 GB of data) to each service.

A few years ago I sampled each of the “All My Music In the Cloud” services (iTunes Match, Amazon Cloud, Google Play).
