Mac OS X doesn't have sha256sum but it does have openssl :)

openssl dgst -sha256 VMwareTools.tar.gz

So the first thing I do is to copy the *.tar.gz into my node working directory (with an cookbook_file statement) after that I will will extract it with an execute command. If this is finished I’ll begin to compare the installation version with the local vesion of the VMWareTools.

Did you create the file in the cookbook's "files/default" directory?

http://wiki.opscode.com/display/chef/File+Distribution

Also, I suggest a couple changes to your resources, noted below:

I would use the "checksum" parameter in this resource to ensure that the file is not copied every time. You will need a SHA256 checksum, and can generate that. On linux, use sha256sum:

sha256sum VMwareTools.tar.gz

Mac OS X does not have a sha256sum binary, but you can generate the checksum with a Chef library :)

ruby -rchef/checksum_cache -e 'puts Chef::ChecksumCache.checksum_for_file("VMWareTools.tar.gz")'

Supply the full path to the .tar.gz if its not in the cwd.

I would have this be action :nothing with a "subscribe" meta-parameter on the cookbook_file resource.

subscribes :run, "cookbook_file[/tmp/VMwareTools.tar.gz]", :immediately

See: http://wiki.opscode.com/display/chef/Resources#Resources-Notifications

In both resources, you do not need the "puts" line, as Chef will display a message about the resource it is configuring at run time.
