I happily used 10.4 for abouit six months. When I upgraded to 10.10 my Update Manager stopped working and at last count there were about 250 updates lined up and waiting. Also my sound configurations misfired (It won't accept my Logitech headset.)
I tried to follow advice from some other forums which didn't work. I also tried all sorts of nonsense myself. I think that now the best thing to do would be to either erase or overwrite whatever is there and start over with 10.10 anew. I can either do without or save whatever might be lost. Most of my important stuff is in the Google cloud. What might the best way for me to get back to work?
Please help, I have had to go back to XP and it is driving me nuts.
