  forTableColumn:(NSTableColumn *)tableColumn row:(NSInteger)row
{
    NSColor *cRed = [NSColor redColor];
    NSTextFieldCell* cCell = (NSTextFieldCell*)cell;
    if ([[tableView selectedRowIndexes] containsIndex:4])
        {
            [cCell setTextColor:cRed];
        }

        {
            [cCell setTextColor:[NSColor blackColor]];

If any of your selected rows in your table include the 5th row (i.e. index 4), this line in your code:

if ([[tableView selectedRowIndexes] containsIndex:4])

hits and you are seeing red in every row being displayed.

Perhaps if you change that line to:

if(row == 4)

(where row is a parameter passed into that method)

You'll just see one row changed to red.

To be honest, this isn't the best place to set a row/cell's color. I think it would be better to set it in your table view data source (e.g. tableView:objectValueForTableColumn:row:).
