How I can find "failed of MacOS update" files and delete it?

[Wick022]

Hello Mac Forums Community

I Need your guys help here

I try hard to upgrade my MBP 15" (mid-2015) from Mojave to Monterey (because this the last OS that I can upgrade), but my net is not that good, its hard to download the update files, the files is so big (12.4GB), so many times is failed and keep failed.

Then I notice, My HD start become full by itself, its only 256GB. I realize this because of the failed update files that keep increase my HD capacity. I check on storage information, there is 150GB "weird files" on System.

So my answer is,
How can I find it, the failed MacOS update files on this Mojave system, on easy way?
Then How can I deleted it permanently?
Are there is the easy way to upgrade my MacOS beside using this way from system preference and do software update? I feel I don't have any chance to success because of my internet connection.

Please give me details answer, since I am not that expert.

Thx for the responds

If you have Install macOS Monterey.app in /Applications, delete it.
Download InstallAssistant.pkg 12.6.1 https://mrmacintosh.com/macos-12-monterey-full-installer-database-download-directly-from-apple/
(the links are from Apple https://swcdn.apple.com….InstallAssistant.pkg)
It will unpack into /Applications/Install macOS Monterey.app
You can start the app to upgrade directly or create a bootable installer https://support.apple.com/en-us/HT201372
Don’t worry about the failed update files, they should be removed after the upgrade.
