[Bug 1050855] Re: External USB keyboard stops working when d-i starts on mac mini

  Thread Previous • Date Previous • • Thread Next 
Parameswaran Sivatharman, as per http://support.apple.com/kb/HT1237 an update is available for your BIOS (MM51.0077.B10). If you update to this following https://help.ubuntu.com/community/BiosUpdate , does it change anything? If it doesn't, could you please both specify what happened, and just provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Thank you for your understanding.

** Description changed:

  Quantal server 20120914 and Precise server 20120913.1 on  mac mini.
  
  The keystrokes of the usb keyboard at the language selection menu of the
  quantal-server-amd64+mac installation are not recognised. Pressing the
  enter key does not enable the installation to progress and the
  installation is stuck at the language selection menu.
  
- The behaviour is very similar to 1017879( fix released), but this time with mac mini on precise and quantal.

+ worked after the installation as well.
