Opening the Extensions manager I spotted several useless items: QuickTime, Color Picker, and Apple Guide. At this time I also dumped the Control Strip…  The Apple Photo Access Extension cannot be removed from the extensions Control Panel, instead, one must drag it out of the extensions folder. Since I’m in the extensions folder I can see there is a Macintosh Guide document which is 1.8MB. I also got rid of Finder Help, About Apple Guide, Apple Built-in Ethernet, and Ethernet (Built-in). After Restarting memory consumption was down to 1557k and it did seem to boot up quicker.
