I have a Macbook Pro, and I am currently running OS X 10.6.8. My first difficulties with Finder started around a week ago. Finder would routinely go unresponsive and I would have to relaunch it. However, after several restarts and shutdowns, that magically resolved itself. I first noticed my current problem when I was trying to use Google Chrome. Chrome would display a new or untitled tab, and would not go to the Google homepage. Additionally, If I typed anything into the search bar it would fail to conduct a search or move out of the new/untitled tab. I decided to reinstall Google Chrome, so I put it in the trash and downloaded it again from the web. However, when I tried to copy the newly downloaded Chrome into my applications folder it said that it could not do so because the file already existed. Glancing at my applications folder I saw that Chrome was not in it. However, when I scrolled down in the applications folder and then scrolled back up to the G section I saw that Google Chrome had magically appeared back in its place. Whenever I attempt to open Chrome it immediately closes itself and I am greeted with the message "Google Chrome cannot be opened because of a problem. Check with the developer to make sure that Google Chrome works with this version of Mac OS X. You may need to reinstall the application. Be sure to install any available updates for the application and Mac OS X." There are no updates available for Chrome or my OS and I have tried reinstalling Google Chrome several times with the same result. I know that this issue is not limited to Google Chrome because it is also affecting other applications. When I try to open Steam it immediately closes itself. I have not tried reinstalling Steam because I expect that the result will be similar to the one I am experiencing with Chrome. Wondering if it was a virus, I decided to download the avast! Free virus scanning and protection software. However I encountered the same issue that I did when I tried to reinstall Google Chrome ("cannot complete the operation because an application with the name avast! already exists", even though I have never downloaded avast! before. Avast! magically appeared in my applications folder, but when I try to open it the application closes without even a message). I have looked through dozens of forum help threads and been to the Google, Apple, and Steam support pages, but I have found no solution to my problem. However, as a result of reading these threads I have concluded that the problem is with Finder, and not with the applications I wish to use. If anyone has experienced my problem before or knows how to fix it please let me know.
