Enable mozilla firefox plugin:

32 bit:
ln -s /usr/lib/jvm/jdk1.7.0/jre/lib/i386/libnpjp2.so ~/.mozilla/plugins/

64 bit:
ln -s /usr/lib/jvm/jdk1.7.0/jre/lib/amd64/libnpjp2.so ~/.mozilla/plugins/
Depending on your configuration, you might need to update the apparmor profile for firefox (or other browsers) in /etc/apparmor.d/abstractions/ubuntu-browsers.d/java

# Replace the two lines:
# /usr/lib/jvm/java-*-sun-1.*/jre/bin/java{,_vm} cx -> browser_java,
# /usr/lib/jvm/java-*-sun-1.*/jre/lib/*/libnp*.so cx -> browser_java,
# with those (or adapt to your new jdk folder name)
/usr/lib/jvm/jdk*/jre/bin/java{,_vm} cx -> browser_java,
/usr/lib/jvm/jdk*/jre/lib/*/libnp*.so cx -> browser_java,
Then restart apparmor:

sudo /etc/init.d/apparmor restart

Mac OS X startup key combinations

Posted on by

Boot key combinations:

  • C : Forces most Macs to boot from the CD-Rom drive instead of the internal hard drive. Only works with Apple ROM drives and with bootable CD discs.
  • D : Forces the first internal hard drive to be the startup disk.
  • N : Netboot (New World ROM machines only) – Looks for BOOTP or TFTP Server on the network to boot from.
  • R : Forces PowerBooks to reset their screen to default size (helpful if you’ve been hooked up to an external montior or projector!)
  • T : Target Disk Mode (FireWire) – Puts machines with built-in FireWire into target Disk mode so a system attached with a FireWire cable will have that device show up as a hard drive on their system. Very useful for PowerBooks!
  • Mouse Button Held Down : Ejects any mounted removable media.
  • Shift : Disables all extensions (Mac OS 7-9), or disables Login items when using Mac OS X 10.1.3 or later. Also works when booting Classic mode up just like you were using the OS natively.
  • Option : When using an Open Firmware “New World ROM” capable system, the System Picker will appear and query all mounted devices for bootable systems, returning a list of drives & what OS they have on them. On “Old World” systems the machine will simply boot into it’s default OS without any Finder windows open.
  • Space bar : Brings up Apple’s Extension Manager (or Casady & Greene’s Conflict Catcher, if installed) up at startup to allow you to modify your extension set.
  • Command-V : Boots Mac OS X into “Verbose Mode”, reporting every console message generated during startup. Really shows what’s going on behind the scenes with your machine on startup!
  • Command-S : Boots Mac OS X into “Single User Mode” – helpful to fix problems with Mac OS X, if necessary.
  • Command-Option : Rebuilds the Desktop (Mac OS 7-9).
  • Command-Option-P-R : Erases PRAM if held down immediately after startup tone. Your machine will chime when it’s erased the PRAM, most people will hold this combination for a total of 3 chimes to really flush the PRAM out.
  • Command-Option-N-V : Erases NVRAM (Non-Volatile RAM). Used with later Power Macintosh systems mostly.
  • Command-Option-O-F : Boots the machine into Open Firmware (New World ROM systems only).
  • Command-Option-Shift-Delete : Forces your Mac to startup from its internal CD-ROM drive or an external hard drive. Very helpful if you have a 3rd party CD-ROM drive that is not an Apple ROM device.
  • Command-Option-Shift-Delete-#(where #= a SCSI DEVICE ID) : Boot from a specific SCSI device, if you have your 3rd party CD-ROM drive set to SCSI ID 3, you would press “3” as the # in the combination.
  • Command-Option-I : Forces the Mac to read the disc as an ISO-9000 formatted disk
  • Command : Boots with Virtual Memory turned off.
  • Command-Option-T-V : Forces Quadra AV machines to use TV as a monitor.
  • Command-Option-X-O : Forces the Mac Classic to boot from ROM.
  • Command-Option-A-V : Forces an AV monitor to be recognized correctly.
