I am on the El Capitan Beta program.
Since upgrading to El Capitan my keyboard on 2011 MacBook Air is not working correctly. All keys are okay apart from the qwertyui keys on top text line. Strangely the ‘p’ character is unaffected. Sometimes these keys will not work at all. At other times the keys will work for a while and then stop operating again. Tried calling Apple telephone support, but they did not have an answer – simply offered to mention to OSX team. Anyone have ideas please? It seems likely to be related to OSX upgrade, but I guess could be a hardware issue that is coincidental timing with the upgrade. Thanks.
