Hello, i updated everything including OS, fuse and the projects; but i never got to see a working preview.

Current versions are:  
macOS: 10.12.4  
fuse: 0.37.0 (build 12978)

When compiling the example (or any other project) i get this:

```auto
cat fuse.log

Hi Filipe,

Can you please try upgrading to 0.38? It is now on pre-release and available here: [https://www.fusetools.com/downloads/channel/qa](https://www.fusetools.com/downloads/channel/qa)

If the problem persists, please paste the log from the log view in the tool in addition to the log you pasted above.

zaulin: Do you get any output in the Fuse log view when this happens?

Also, both of you: Could you please try `uno build -r -tdotnet` and see if the app shows up there, or if it’s still blank?

Thanks zaulin. It seems like this is an issue with our font renderer on your CPU. There’s a known issue about this, but we don’t have a workaround at the moment. Could you try `uno build -r -tdotnet -DDISABLE_HARFBUZZ` though? That will disable the Harfbuzz font renderer. Disabling this does unfortunately not work in preview, we will let you know when this is fixed.

Filipe’s issue might be something else, I’ll follow up when I see some more output from you.

Hello!

with Fuse 0.37.0  
`uno build -r -tdotnet -DDISABLE_HARFBUZZ`  
it showed a running app on the desktop!

Its just not attached to the preview window… (i assume thats the “not work in preview” thing)

```auto
Uno 1.0.8 (build 5347) OS X 10.12 i386 9d93c90

Configuring (1.6 s)
Compiling syntax tree (4.9 s)
Generating code and data (13.0 s)

Build completed in 19.54 seconds

```

With `uno build -r -tdotnet` still gives that huge error

Filipe, can you please include a bit more of your log, especially that part where it prints `GL_VERSION` and `GL_RENDERER`? Also, can you please let me know the Mac model you’re using, especially the CPU model?

Ok, that’s consistent with what we’ve seen before. It seems like Harfbuzz has an issue on that particular CPU. I’ll let you know when we have a fix or a proper workaround available. In the mean time you’ll have to use an older version of Fuse, or use `uno build -r -tdotnet -DDISABLE_HARFBUZZ` without live reload functionality.

Hi HarrisCreativity

Please include the full output from the log view in order for us to be able to investigate this. It would also be helpful to know your hardware specs, especially your GPU and CPU models.
