Apple released OS X 10.5.11. The new release is bringing bug fixes and performance enhancements.
I hate it when my work day starts with upgrading my iMac. The new released OS X 10.5.11 is here, marking the 5th El Capitan update. After downloading several 100 megabytes the update took about 30 minutes with two reboots during the update process on my SSD equipped iMac.

After the update finished only Safari had some initial issues with eating up memory. After closing and starting Safari again all works fine. I am using now OS X 10.5.11 since about 5 hours and so far no problems and also no system slow downs. I have the regular issue that my iMac slows down as usually Firefox hogs the CPU and uses lots of RAM. on OS X 10.5.11 the current Firefox version 46.0.1 is behaving so far. Chrome also runs fine as usual.
You counted right, I use three browsers simultaneously and sometimes also Opera for VPN connections and use of Google without being logged in. The web is a a complicated work place.
