As per https://developer.apple.com/support/xcode/ Xcode from 14.0 no longer supports targeting 10.9, and attempting to do so may fail in obscure ways.

10.13 is still 5+ years old, so we retain coverage for a reasonable range on macOS versions.

Closes #17451.

     Use getRunfilesPath for run_under executable path generation.

     external source files anymore after the recent external source

     [4.2.4] Bump minimum supported macOS versions to 10.13 (#18047)

Incompatible changes:

  - GrpcRemoteDownloader only includes relevant headers instead of
    sending all credentials.

    Closes #16439.

Important changes:

  - Multiplex persistent workers can now use the JSON protocol.
  - enforce config_setting visibility. See
    #12932 for details.
  - The minimum Android build tools version for the Android rules is
    now 30.0.0
  - Updates worker protocol with cancellation fields, and adds
    experimental_worker_cancellation flag to control cancellation.
  - If all strategies of one branch (the local or remote execution
    branch) of the `dynamic` strategy fail to even accept (via the
    response they give from `canExec`) the action, `dynamic` will now
    try to see if the other branch can accept it. (Trying to run it
    and it failing will still cause a failure if it was the first
    result, this is about strategies claiming they can't even try the
    action)

   + a689d67:
     Use getRunfilesPath for run_under executable path generation.

     the --nolegacy_external_runfiles becomes default. This fixes

     [4.2.4] Bump minimum supported macOS versions to 10.13 (#18047)

Incompatible changes:

  - GrpcRemoteDownloader only includes relevant headers instead of
    sending all credentials.

    Closes #16439.

Important changes:

  - Multiplex persistent workers can now use the JSON protocol.
  - enforce config_setting visibility. See
    #12932 for details.
  - The minimum Android build tools version for the Android rules is
    now 30.0.0
  - Updates worker protocol with cancellation fields, and adds
    experimental_worker_cancellation flag to control cancellation.
  - If all strategies of one branch (the local or remote execution
    branch) of the `dynamic` strategy fail to even accept (via the
    response they give from `canExec`) the action, `dynamic` will now
    try to see if the other branch can accept it. (Trying to run it
    and it failing will still cause a failure if it was the first
    result, this is about strategies claiming they can't even try the
    action)

   + a689d67:
     Use getRunfilesPath for run_under executable path generation.

     [4.2.4] Bump minimum supported macOS versions to 10.13 (bazelbuild#18047)

Incompatible changes:

  - GrpcRemoteDownloader only includes relevant headers instead of
    sending all credentials.

    Closes bazelbuild#16439.

Important changes:

  - Multiplex persistent workers can now use the JSON protocol.
  - enforce config_setting visibility. See
    bazelbuild#12932 for details.
  - The minimum Android build tools version for the Android rules is
    now 30.0.0
  - Updates worker protocol with cancellation fields, and adds
    experimental_worker_cancellation flag to control cancellation.
  - If all strategies of one branch (the local or remote execution
    branch) of the `dynamic` strategy fail to even accept (via the
    response they give from `canExec`) the action, `dynamic` will now
    try to see if the other branch can accept it. (Trying to run it
    and it failing will still cause a failure if it was the first
    result, this is about strategies claiming they can't even try the
    action)

     [4.2.4] Bump minimum supported macOS versions to 10.13 (bazelbuild#18047)

Incompatible changes:

  - GrpcRemoteDownloader only includes relevant headers instead of
    sending all credentials.

    Closes bazelbuild#16439.

Important changes:

  - Multiplex persistent workers can now use the JSON protocol.
  - enforce config_setting visibility. See
    bazelbuild#12932 for details.
  - The minimum Android build tools version for the Android rules is
    now 30.0.0
  - Updates worker protocol with cancellation fields, and adds
    experimental_worker_cancellation flag to control cancellation.
  - If all strategies of one branch (the local or remote execution
    branch) of the `dynamic` strategy fail to even accept (via the
    response they give from `canExec`) the action, `dynamic` will now
    try to see if the other branch can accept it. (Trying to run it
    and it failing will still cause a failure if it was the first
    result, this is about strategies claiming they can't even try the
    action)
