Thank you. I just found the updates, but I received this message when I tried to download them: This update is not available for this Apple ID either because it was bought by a different user or the item was refunded or cancelled.
I tried going to the terminal and typing in "sudo software update --clear-catalog" but that didn't help. I also tried typing in "open $TMPDIR../C/ in the terminal" I then deleted the "com.apple.appstore" directory. That didn't help either. I'm still getting the same error message. Any ideas as to why I can't download my needed software updates?
