Hi - wonder if someone can give me some guidance... My Macbook Pro (10.5.2) is acting strange in two respects. Problem has started about 2 days ago. 1st - Finder App: on startup, if I try to click on the finder icon on the dock I get an error 'cannot find the application'. However if I click on the 'downloads' icon and then click 'finder' on the downloads list, the Finder finally opens and is accessible from the dock from there on. One more note: from startup until I go to downloads the bar at the top of my mac (with the clock, etc) is not present. It comes back though after I click downloads. 2nd - Time Machine: I noticed my time machine icon was not loading on the top bar next to the time. So I went to my preferences and Time Machine looks like it is off. I did not turn it off. However I can't turn it on as it is locked. On clicking the lock I am not asked for a password, nothin. So I cant turn on Time Machine. I have tried repairing permissions on my mac hd in the disk utility. This did nothing. My Time Machine was running up to about 2 days ago - is there a way to rollback the entire system to then maybe? Or should I just try and repair these two individual issues. Thanks for any help you can offer.
