Mac OS X Hints

NFS debugging

You can turn up verbose debugging:

nfsd verbose up; nfsd verbose up; nfsd verbose up; nfsd verbose

And look in the logs:

log show --predicate 'process == "nfsd"' --debug --info

Bootable Linux USB

How to create a bootable USB:

diskutil list
diskutil unmountDisk /dev/disk6
sudo dd if=/Users/nagler/d/Fedora-Server-DVD-x86_64-23.iso of=/dev/rdisk6 bs=1m
diskutil eject /dev/disk6

For Ubuntu:

hdiutil convert -format UDRW -o ~/path/to/target.img ~/path/to/ubuntu.iso

Camera is turned off

This happened with my Cinema Display. This fixed it:

sudo killall VDCAssistant

VirtualBox crashing

Do not enable audio in your VirtualBox VMs. It will be on by default so you have to turn it off in the vagrant's box directory:

VBoxManage modifyvm "$(cat .vagrant/machines/default/virtualbox/id)" --audio none

See how to do this in the Vagrantfile.

GLX Mode in Xquartz

If you see this error:

libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast

You should run:

defaults write org.macosforge.xquartz.X11 enable_iglx -bool true

(On Windows, you might have to add +iglx, but this isn't tested or known to be a problem.)
