When I tried to install the Fuse package, I get an error that it’s installation is not compatible with the System Integrity feature; if I choose continue anyway, the installation ends up failing.
I’m on El Capitan 10.11 beta 6.
Is this a known issue?

At the moment we have not tested the Fuse beta on the El Capitan beta, unfortunately. We will probably get to this in the not-so-distant future, but until El Capitan reaches production quality we would rather make sure the Fuse beta runs well on Yosemite.
Sorry if that’s not the answer you were hoping for 
bummer 
Can you try the following workaround (which we picked up from the Mono framework site):
- Restart in Recovery mode (hold [cmd]+[R]).
- Select Utilities > Security Configuration
- Uncheck “Enforce System Integrity Protection” and restart.
- Check mono in Terminal to see if it works and if the command is not recognised then reinstall mono MDK to activate it - http://www.mono-project.com/download/
The reason why this is an issue is that Apple made some dramatic changes to OS X in El Capitan by making /usr/bin read-only, even with root access.
The installer is placing stuff inside /usr/bin (and so is Mono, Xamarin and a ton of other developer software), so thankfully this is a known issue.
Starting with yesterday’s release (0.5.6000), we now have experimental support for El Capitan.
However, we have found that the “Mono preview package for El Capitan” seems buggy, and recommend that you use the normal Mono for Mac OS X instead, which also actually works on El Capitan. So make sure you select the normal (not preview) MDK from http://www.mono-project.com/download/.
