On installing the new OS a problem with logging on after the machine has been asleep started immediately. Occasionally my keyboard input is ignored and, after a brief pause, junk was loaded into the login input field. When I extend the time-out before the machine goes to sleep I get the same occasional reaction when I go back in without needing to login, but this time it's with typing into URLs in the browser. When the happens I always have to reboot!

Technical people at Apple, who placed 'Capture Data' app on my desktop, say the problem originates with home-brew, my package manager! I've since reinstalled homebrew as suggested on several sites so it will work with El Captain.



I still get this issue occurring in a random fashion about 10%+ of the time.

Related to this issue? I can't install all that I need to set up IPython. Here pip doesn't always work.

Same results when I try to install psycopg2!

Any suggestions on fixing the initial problems and getting stuff installed?



The only way I've found to do the installs I need is to disable SIP! Was attempting to avoid this but it seems the way to go.

Do not know yet if the login issues is still unresolved!

Note: Login Issue NOT resolved!
