Every so often Mac downloads/dumps software on my computer. It calls it 'Software Update'. It's megabytes upon megabytes of updates for applications I never use so I don't accept them. My question is, are all these downloads kept on my laptop waiting for me to activate them? If yes, where are they kept and... how can I get rid of them? I don't mind security updates, but... How can I prevent apple from dumping 'updates' on me for applications I never use?
