Download macOS Mojave 10.14.5 Combo Update - Apple Support https://support.apple.com/kb/DL2001

after downloading before you launch the installer, boot into SafeBoot

SafeBoot https://support.apple.com/en-us/HT201262

Takes noticeable longer to get to the login screen, does a 5-15 minute disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, etc. Log in and run the Combo

Thank you very much, i am now able to update.

The issue was that i was on Mojave 10.14.2 and updating to 10.14.5 required a minimum version of 10.14.4 which i did not meet.

i needed to do an incremental update before updating to 10.14.5.

thank you for the help.

Thanks for the response and sorry for my late reply.

I tried installing the Combo update in safe mode but encontered an error saying the volume does not meet the requirements for the update.

I have over 300 GB of free space available on the volume so i do not understand the error.
