Hello,
Total newbie here so please go easy on me! After downloading Snow Leopard, if I make a new folder and drag it into the Finder side bar, I cannot get them to delete. I drag my cursor over the other folders and they highlight...when I get to the new folders, they will not highlight as if they are "locked" into the sidebar.
you should be able to simply drag them off the sidebar. it doesn't matter if it's highlighted. just click on a folder in the sidebar and without releasing the mouse button drag it off the sidebar.
Open a Finder window and select your Home Folder in the Sidebar on the left.
Then open Library folder, then open the Preferences folder.
That file will be in the Preferences folder. Drag that file to the Trash, empty the Trash and restart your Mac.
Hopefully you will be able to delete those files now.
Also, repair disk permissions.
Quit any open applications/programs. Launch Disk Utility. (Applications/Utilities) Select MacintoshHD in the panel on the left, select the FirstAid tab. Click: Repair Disk Permissions. When it's finished from the Menu Bar, Quit Disk Utility and restart your Mac. If you see a long list of "messages" in the permissions window, it's ok. That can be ignored. As long as you see, "Permissions Repair Complete" when it's finished... you're done. Quit Disk Utility and restart your Mac.
