Some Zwifters are reporting game crashes on Mac following update to Mojave OS 10.14

Hey Zwifters,
Some users are reporting that Zwift is crashing at launch and/or having start up issues following a Mac update for OS 10.14/Mojave. OS versions before Mojave are reported to be working more efficiently. I’ll update this post as we receive new information. Thank you for your patience!

Thanks for posting! I’ve been scouring the forums looking for anything on this topic. My specific issue is that although the app recognizes my Kickr as the power source when loading it doesn’t register any watts once I start pedaling. Cadence and HRM do show up on the ride screen. I was really hoping to participate in Tour de Zwift.

MacBook Air Early 2014 Mojave OS 10.14.2.

@Jacky_Gunawan These both sound like slightly separate issues from the one mentioned in the original post. Can you all send in a support conversation if you haven’t already? We’ll be able to help you out there :slight_smile:

I have the same issue. Zwift makes connection with my bluetooth device (Tacx Neo Smart) but says ‘no signal’ about 4secs later.

Tacx is up to date and does work with Zwift App & Tacx Utility software.

Last time I had this issue I had to update my Mac OSX software to the latest version of Mojave. So I did that (10.14.2), But it did not fix the issue.

it worked a few days ago though

Using Apple Mac, wont start up after log in

Same problem here - crashes after login but before the ride begins… Error logs sent to the zwift email address

Nope. Nothing to complain here. (apart from integrated Intel graphics being utter crap)

macOS 10.14.2 (up-to-date)
Wahoo KICKR SNAP MY17 (latest firmware)
Wahoo TICKR X (latest firmware)
The only problem I have ever encountered was a few sudden bluetooth drops, lasting a few seconds which came with earliest Mojave release. But that was a long time ago. (fixed by OS updates, presumably)
My most recent issues were exclusively server-side problems.
