I just checked my applications folder and there is an Install macOS High Sierra file this is 5.21 GB. I'm guessing that at some point I must have downloaded the update but never installed it. I am not planning to upgrade to High Sierra any time soon. 1. Can I delete this file without any issues? 2. Does it make sense to just keep the file if I intend to update to High Sierra in the next 6 months OR should I just delete it and re-download the most up-to-date version when I'm ready to upgrade to High Sierra? Thanks.
