SpotX-Bash and Code signing (macOS)

[jetfir3]

Due to the nature of some of the patches made by SpotX-Bash and macOS security, by default, SpotX-Bash now code signs the client after running. Code signing is a method of (re)signing the app using official tools from Apple -- the codesign binary is now a required dependency for SpotX-Bash macOS users and is checked at launch.

Unfortunately, code sign tools do not come with macOS by default and are an additional download. It's possible users may already have these tools installed. Users without code sign tools will receive an error when launching SpotX-Bash if they do not. To download and install these tools directly from Apple, the following command can be entered into the Terminal app:
xcode-select --install

Note: This does not install the complete Xcode package, only the Command Line Tools, which include the tools required for (re)signing apps/binaries/etc.

If users wish to skip the codesigning process and avoid downloading and installing the Command Line Tools from Apple, the --skipcodesign argument can be used to skip both the codesign dependency check as well as the codesigning process. Depending on macOS version, Gatekeeper settings and SIP settings -- skipping the codesigning process may cause the client to no longer launch after using SpotX-Bash and reinstallation of Spotify would be required.

As Gatekeeper and SIP are "security features" built into macOS, SpotX-Bash does not suggest users disable these features. The choice is left to the user. Those who have already disabled Gatekeeper and/or SIP and do not wish to install Xcode Command Line Tools may not run into issues launching Spotify after using SpotX-Bash with the --skipcodesign argument.
