Software Update Disk Space Issue

Hi, I am trying to update the software from macOS Monterey 12.5 to 12.6.


The notification mentions that the "system update requires 18.76 GB of free disk space".

I have close to 109 GB of free disk space available.


Even though there is enough disk space available, I am notified with the same error.

"Your disk does not have enough free space".


What should I do?

I've had better luck installing system updates/upgrades from the Safe Mode because I evidently have some 3rd party software that interferes with the installation so try the following:

#1 - boot into Safe Mode according to Start up your Mac in safe mode - Apple Support.

NOTE: Safe Mode boot can take up to 3-5 minutes as it's doing the following; 
• Verifies your startup disk and attempts to repair directory issues, if needed
• Loads only required kernel extensions (prevents 3rd party kernel/extensions from loading)
• Prevents Startup Items and Login Items from opening automatically
• Disables user-installed fonts 
• Deletes font caches, kernel cache, and other system cache files

#2 - go to the System/Software Update preference pane and begin the download.

#3 - run the installer from the Safe Mode.
