Report Is Resilio Sync still being actively developed? in Sync General Discussion Posted April 26 I started a thread here in November of last year asking about explicit support for M1 Macs. Everyone on this thread is already well aware that we haven't seen or heard anything since that time. In fact, the last Mac release (2.72) was motivated by another Mac issue I reported which made it impossible to sync a Photos Library on Big Sur. Resilio continues to function on M1 Macs but it stands out as a high consumer of both CPU and battery. I rarely see it drop below 4% CPU, and it's often using much more CPU than that. This is when there is no disk activity whatsoever in any of the folders that it syncs (on the local or remote machines). At least according to Activity Monitor, the only process that provides any real competition for energy consumption is Time Machine. There are a couple of other bugs/issues that I consistently run into but it doesn't seem worthwhile to report them. We can speculate on why Resilio seems to have become abandonware - lack of market opportunity / support, focus on other products, legitimate and sincerely awful geopolitical issues - but unless someone knows otherwise, it's just speculation. With respect to Mac software, we're now seeing the second generation of M1 devices hit the market and there is obviously no going back. Resilio needs to see some M1 love in the form of a focus on CPU and energy use reduction. My guess - which is reasonably informed - is that the shortest path to that outcome is a native ARM build, but I think there's work left to do around change detection, too. The original poster asked "Should I pay?" Frankly, a Resilio license is a good deal and it's a great product. But it seems possible that we are never going to see another release. So the decision to buy a license surely is not an easy one.
