I downloaded and installed the 10.4.3 update onto my: ibook 14 in 133 mhz 1.25 g ram On reboot, it took forever to start Mac osX. Then after I entered my password at login screen I got the spinning beachball for about 10 minutes with no progress. I hit the power button and did a restart and the same thing has now happened -- long long startup (10 minutes) and spinning beachball after login that won't stop (it's now been another 5 minutes). What should I do? Thanks in advance from a newbie who until this point has had not problems.
