Related issue: #2205

We need to improve the installation scripts in the macOS packages so we can avoid using temporary files to share information between pre and post-install.

Proposed solution: Use pre and post-upgrade scripts.

Update

Separate tasks are currently done in pre-install and post-install scripts between pre-upgrade and post-upgrade.

Create new scripts, build new package, and start testing.

I have initiated the development phase, concentrating on refining both the preinstall and upgrade scripts. I have pending tests to run and a pull request (PR) to create.

Move to block; this will be addressed in issue 21755.

I reviewed the changes introduced at wazuh/wazuh#21755 and have started working on the issue again.

Update

I tried to implement a proof of concept, but it didn't work. I created dummy preupgrade and postupgrade scripts, but they weren't called.
I found this document that may offer some clues on how to do this. I'll keep digging based on this lead.

Update

I was unable to find a way to implement the proposal. After reading this comment, it appears that preflight/postflight/preupgrade/postupgrade functionalities are no longer supported. Therefore, I made some improvements to the scripts, but I still need to test them.

Update

Made some more improvements and did some testing. All good to go for review now.
