istat menus, esata, si3132, quicksilver all work now
As mentioned elsewhere, istat menus are updated, si3132 drivers from the silicone images site work, and quicksilver worked after deleting all and reinstalling. The last one that doesn't work for me is insominiax, but sleepless is a commercial program that has been updated and does work. Finally, I had a nice widget for running maintenance scripts that no longer accepts my password. Luckily tinkertool system takes care of that.
So, I'm now upgraded and all is working well.
