Topaz Video AI 5.1.1 (macOS)

In the update from version 5.0.4 to 5.1.0, the developers changed the structure and addresses of key instructions in its code. This means the old patch, which modified specific hex values, no longer works because those values have moved. We are going to need a new patch.

I've managed to create a new patch that works with the latest version of Topaz Video AI (5.1.1). This version isn't listed on the official download page (topazlabs.com/downloads) where you can only find version 5.1.0. However, you can download version 5.1.1 directly from the following link:

https://downloads.topazlabs.com/deploy/TopazVideoAI/5.1.1/TopazVideoAI-5.1.1.dmg

The new patch ensures that all necessary dylib files are correctly linked and that the binaries are appropriately patched. Here are the steps included in the patch:

1. Downloads Necessary Files: Downloads the older version (5.0.4) and extracts specific files needed for the patch to work on newer versions of Topaz Video AI.
2. Symbolic Links: Creation of symbolic links to ensure the application can locate the required dylib files, matching the structure of the previous version.
   
3. Hex Replacement: Specific hex values in the login and libvideoai binary files are patched to bypass activation checks.
   
4. Preparation: Clears extended attributes and re-signs the application to ensure it runs without issues.

Code:

function hex() {
    echo ''$1'' | perl -0777pe 's|([0-9a-zA-Z]{2}+(?![^\(]*\)))|\\x${1}|gs'
}

function replace() {
    declare -r dom=$(hex $2)
    declare -r sub=$(hex $3)
    sudo perl -0777pi -e 'BEGIN{$/=\1e8} s|'$dom'|'$sub'|gs' "$1"
    return
}

function prep() {
    sudo xattr -cr "$1"
    sudo xattr -r -d com.apple.quarantine "$1"
    sudo codesign --force --deep --sign - "$1"
