OSX 10.11.1 (el capitan) freezing with Arduino upload

Hi folks.
Anybody else experiencing this?
Only since I updated to 10.11.1.
Uploading via my FTDI Friend randomly causes the whole Mac to lock up.

:confused:

Same is happening to me. I have search a fix for three weeks, and i can,t upload anything.

I have an original UNO R3, but tried with a Pro Mini with the same results.

Time to wait I think.

If you see an answer for the problem, please post it.
