Reverse Engineering on macOS

Some notes, tools, and techniques for reverse engineering macOS binaries.

Onyx Boox handwriting optimisation in any app

All credit to this thread for figuring out how to do this, I'm just documenting it more thoroughly.

Tested on Nova Air C with firmware 3.5 (2023-11-20).

Handwriting optimisation makes the pen usable in apps installed from the play store. By default it's only available for OneNote, Evernote and WPS -- they have a 'handwriting' tab in the optimisation settings, other apps don't -- but can be enabled for any app by editing the file /onyxconfig/eac_config as root.

Note: whenever you edit eac_config, you have to reboot the device for the changes to take effect. Just restarting the app isn't enough.

Set GOPRIVATE to match your github organization

I keep fixing this up, but if it fails for you, check if these are better maintained https://tip.golang.org/cmd/go/#hdr-Configuration_for_downloading_non_public_code and https://golang.org/ref/mod#private-modules.

Cloning the repo using one of the below techniques should work correctly but you may still be getting an unrecognized import error.

As it stands for Go v1.13, I found in the doc that we should use the GOPRIVATE variable like so:

GOPRIVATE=github.com/ORGANISATION_OR_USER_NAME go get -u -f github.com/ORGANISATION_OR_USER_NAME/REPO_NAME

The 'go env -w' command (see 'go help env') can be used to set these variables for future go command invocations.
