Should we be worried about folder Biome, and the BiomeAgent and biomesyncd processes?
I restarted my Intel iMac after a long session of two weeks without any restart. As soon as my system rebooted, I saw that I had only 5 GB available in my hard drive, which usually I keep above 100GB free. I immediately wonder if I had downloaded a lot of content or if my FinalCut Pro renders or anything else had a significant large cache or render files. I didn't see anything. I immediately open many folders/directories with the "Show folder sizes" option and was able to see a Biome folder with about 113 GB stored in there. I am not sure I had ever seen a folder named Biome in my user Library folder (~/Library/Biome/), there is not one in the Main Library folder.
I have found so little information in this Apple community, and not so much on the web, either.
Since my computer could not work well, I took the risk of deleting the whole Biome Folder and force quitting two processes by the name BiomeAgent and biomesyncd. It seems like nothing was affected by my quitting these processes and deleting the folder, then I wonder who do they belong, too? Are there any Apple engineers that can confirm these processes are part of Apple? Can there be bugs that will track more than 2,200 files about every four minutes or so in one day inside the /Users/username/Library/Biome/streams/restricted/MailContent directory, or anywhere inside the Biome folder for that matter??
Anyone else has encounter this issue? It sounds like something is happening in behind the scenes, information is shared, the drive is storing and streaming somewhere or to someone. I'm worried this is a a malware or a Trojan horse, hopefully is just a bug, but I'd like to know directly from someone at Apple, or from anyone with more knowledge.
I'm sharing some screen shots to see if we can get to the answer of this.
This is a very large folder with many consistent set of files stored. Concerning if these are streams, where?
After deleting the Biome folder entirely, and restarting, the folder was rebuilt/reconstructed, alas smaller in size. But here is a view of its structure after restart.
