macOS Monterey 12.6 upgrade won't install

When upgrading from 12.39 to 12.6, I can download but not install the upgrade. I can successfully download the upgrade, but get an error saying the download can't be used because it's damaged. Any workarounds or advice?

Update issue while updating macOS from Monterey 12.5 to 12.6 Hi, I have tried to update macOS Monterey 12.5 to 12.6 recently. But failed 5 times. I tried with safe mode also. But each time I try to update, it downloads fully but it is stuck at "Preparing macOS Monterey 12.6...", and " About 30 minutes remaining". This is a MacBook Air M1. If anybody has faced this issue and sorted it out, please let me know the solution. Thanks in advance.

Monterey 12.5 Update fails to prepare update Hi everyone: I have tried to update to macOS Monterey 12.5 three times, and the same thing keeps happening. It says that there was a failure to prepare the update. So, the update is completely downloaded and then hits this problem and tells me to try again later. Anyone know why this is happening? Thank you in advance!

Contact the software manufacturer for assistance." I'm using a Macbook Pro, 2017 with touch bar.

Yes. Sometimes a large file such as this can get damaged during the download and it then will not install. Put the file into the Trash and do another download. Sometimes the problem is that using Wi-Fi is too slow and is the cause. If so, use a wired Ethernet connection and it should download just fine.
