Back to my Mac problems under Yosemite

My Back to my Mac functionality generally doesn't work. The remote Macs only show up at random times. I've turned off BTMM and back on on both machines multiple times, even off, then a reboot, and finally back on with no success. This is generally buggy.

I'm seeing the same problem. I maintain all of my family's computers remotely using B2MM. I can't see any of them anymore.

B2MM was working great until I installed Yosemite, not they won't show in the finder.

Back To My Mac worked great in Mavericks but now it seems to have died completely in Yosemite and like you, I changed NOTHING on my network at either end of the connection. Very frustrating.

Worked most of the day yesterday, BTMM works very about 30% of the time. Most of the time remote macs only show if on the local network. Even if a WAN Mac is in the Finder shared list you can only connect about 50% of the time. I installed Chrome Remote Desktop works really well. No Port Forwarding required. , does not require or use UPnP. Just sign in to your google account once. When Apple get Yosemite fixed I will switch back.

Same here. Since installing Yosemite, I'm not able to screen share or access files from other macs on the WAN (and I am using the Apple Airport router) It worked before in Mavericks, and it's kind of a bummer since I have been relying on it. Hope Apple gets this fixed soon.

Works okay for me for macs in the same office but connecting remotely rarely works. It was bad with Mavericks, but is awful with Yosemite.

I've just updated to OS X 10.10.1 and BTMM seems to be working again. I'll need to do more testing to be sure, you all might want to give it a try...

The 10.10.1 update today seems to have fixed BTMM. The Shared Mac took a couple of minutes to appear in the Finder window Sidebar, but the connection was made OK. Screen Share worked OK, too. My BTMM had not been working since the upgrade from Mavericks to Yosemite two weeks ago.

Even after latest update, mine still is not working when I am on an external network. while on the same network it works every time, but seem to block out a lot more often than it did on Mavericks.

Since my last post on 11/17/14 (updated to 10.10.1), there was one occasion where the remote Mac appeared in the Sidebar, but it would not connect via BTMM. I had connected OK a couple hours previously. When the remote Mac was restarted, the BTMM connection was sucessful (??).

Still only working on the LAN for me....never works remotely. Google works great though.

Google doesn't accomplish what I need regarding remote connections. I discovered my shared Mac can be connected via BTMM if I open a new Finder window. The shared Mac may take a couple of minutes to appear in the Sidebar, but when it does, BTMM connections are successful. Subsequent connections require closing the previous Finder window, opening a new Finder window and waiting a couple of minutes for the shared Mac to appear in the Sidebar. I reported this quirkiness to Apple.

I was having this problem as well. I could connect to another Mac on my LAN at work, but I couldn't connect to, or even see, my Mac at Home. I also couldn't connect to or see either Mac at work from home. Perhaps it's just coincidence, and it seems weird, or maybe Apple made some change on their end, but after updating the home Mac and 1 of the work Macs to Safari 8.0.2, I noticed that the work Mac is showing up in the finder and I can connect to it for file and screen sharing. I still don't see the other Mac at work that has not yet been updated to Safari 8.0.2. This is only one successful session, and it's possible it may not be working again tomorrow, but right now it seems to be working for the first time since upgrading to Yosemite.

Yosemite has been 10.10.1 on all systems involved since shortly after it was released.

I'm not sure about the Safari 8.0.2 connection, because my BTMM was working before I updated Safari. With my setup, there are still BTMM behavioral differences since updating from Mavericks to Yosemite (plus 10.10.1 update). The BTMM shared Mac takes longer to appear in the Sidebar (sometime 2 or 3 minutes), but once a connection is made, Finder tasks on the shared Mac are much faster than before.
