WP 4.3.1 new install on localhost missing php.ini

I've installed WordPress on my localhost Mac OSX Yosemite box. I'm getting error:

The uploaded file exceeds the upload_max_filesize directive in php.ini

phpinfo() reports upload_max_filesize = 2M

I noticed that there was no php.ini inside the wp-admin folder of the WordPress default install, so I placed one there with upload_max_filesize = 64M.

I placed the php.ini into the wp-admin directory of the site I'm working. Unfortunately, I still get the error message. And phpinfo() file located in root directory of the site still reports upload_max_filesize = 2M

Any ideas how to resolve? The only other php.ini file I have is under:

private/etc/php.ini.default

I've edited that one to 64M as well, but no change in phpinfo() still.

The WP install is a brand new zip of 4.3.1 from wordpress.org
