How to prevent MacOS system update redownloading from scratch?

[airlied]

I'm on MacOS 10.14 Mojave.

My ****** ISP doesn't allow me to download 'a large mount' of file within short time. And it has a cap of 10GB per day limits.

So when I got a system update (usually have 2~3GB worth of data), I cannot get a full download in one try. It stops after downloading 400~500MB then goes back to 'check for updates' stage. I have to manually click download again.

The problem is, everytime it does this, it restarts from the beginning! This is really annoying. I have already wasted many gigabytes today just for trying to download the updates.

There is nothing I can do about the stupid crappy internet, but how can I get my mac remembered how many data it downloaded so it could pick up from where it left off? Please help me.

What I'd suggest:

First, TURN OFF all "automatic" updates of the OS and any other software.
You can do this in the software update pref pane, I believe (I'm not running Mojave at the moment).

Now, when updates are announced (by Apple or anyone else) you can "pick and choose" what to download, and what to leave until later.

When a system update is released, wait until it "shows up" as a "combo updater" in Apple's software downloads.
Then, MANUALLY download the updater utility (these will be smaller than 10gb).

Now, you can "apply the update" after it's downloaded.

See if this works out any better.

THE VERY LAST THING I want is "automatic updating" of my software. I don't like ANYONE "downloading behind my back". I'll download updates manually and apply them when I choose to do so, thank you very much!
