Aug 23, 2012 I ran the Updates feature in the App Store on my iMac today, and it reported both a delta (incremental) update to Mountain Liion to 10.8.1, and a full download of the 10.8.1 Combo (4.37GB). After running the delta update, I decided to download the full Combo version, just in case I ever needed to do a full reinstall. Jul 24, 2016 Where the Downloads Folder Location is in Mac OS In all versions of Mac OS X and macOS, the user downloads folder is located in the users Home directory in a folder appropriately called “Downloads”. The relative path for the Downloads folder in MacOS is /Downloads/ while the exact path would be /Users/username/Downloads/. Apple helps you keep your Mac secure with software updates. The best way to keep your Mac secure is to run the latest software. When new updates are available, macOS sends you a notification — or you can opt in to have updates installed automatically when your Mac is not in use. MacOS checks for new updates every day, so it’s easy to always have the latest and safest version.

- You can use macOS Recovery to reinstall macOS.
The <blahs> appear to be some hash of either the computer or the software being downloaded. Try the following:
Open a Terminal
sudo find /private -name ' SomePartOfTheDriverNameYouAreLookingFor' -print
then sudo cd <the directory shown above>
Note I don't see /private in finder because of the permissions on it (hence the need for sudo above).
Also note, I had one directory in <blah> named -Cache- which is tricky to cd into because the leading - is perceived as an argument to cd, so I just cd into the entire directory path instead.
Finally, be wary doing things as root (sudo) as you can end up damaging your OS (so don't go around removing files you are not sure about)
