Additionally, you can safely delete Log files, but not the folders that own them. There is a nightly script that runs to delete them in Mac OS X as long as you are in screen saver, but not always in Energy Saver, or they are deleted right after the machine wakes from sleep. The latter function could. Theoretically, there should only be updates in that folder until you actually run the updates, then they should be cleared - so my first suggestion would be to check the App Store app & run any pending updates from there, reboot, then recheck the folder. Catalina now installs /System as part of a read-only volume, so it cannot be altered whilst in use. You can modify or delete those files when booted to Recovery, but bear in mind that Apple may well restore them in an update to the OS.
Here's what you need
- There are files taking up space on your Mac that, since updating to macOS Catalina, you simply can't use. Here's why you've got them and when they should be deleted.
- Force delete the file. If all else fails, another terminal command can force file deletion. Enter “sudo rm -r path to the file”. In most cases, this command will delete the file once granted administrator permission with the password.
- Update your iPhone or iPod touch to the latest version of iOS, iPad to the latest version of iPadOS, or Mac to the latest version of macOS. On a PC, make sure that you have the latest version of iTunes for Windows.
- Subscribe to Apple Music or iTunes Match.
- Sign in to all of your devices with the same Apple ID that you use with Apple Music or iTunes Match.
- Connect your devices to the Internet over a Wi-Fi or cellular network. On a Mac or PC, you can also connect to the Internet using Ethernet.
