Dependency Issue for 4.1.9

Context

After a long while I've restarted Sourcetree on mac. Upon restarting it errors with this:

'git log' failed with code 6:'dyld: Symbol not found: ___darwin_check_fd_set_overflow
  Referenced from: /Applications/Sourcetree.app/Contents/Resources/git_local/bin/git (which was built for Mac OS X 12.4)
  Expected in: /usr/lib/libSystem.B.dylib
 in /Applications/Sourcetree.app/Contents/Resources/git_local/bin/git
' 

So:

 - My mac is on 10.14 Mojave.

 - Looks like from the 4.1.9 release notes that git was upgraded, and apparently to a version that requires Mac 12.4.

 - After some effort, the work around was to switch Sourcetree to use the system git.

Expected Outcomes

 - Please put out a new release 4.1.x that provides a version of git that supports Mojave so that affected users can simply "upgrade" their version out of this issue.

 - Please update your release notes. The CVE is double pasted so the link is broken.

 - Please be more conscious about OS support of your 3rd party integrations.
