Q: i am connected to iTunes on my Mac with my iPad 2 and it will not reset.  Please advise.

You have an issue.

iOS 9 and later require a more current version of iTunes than you can possibly run using such an old OS X version (Lion).

The current iTunes version, iTunes 12.4.3, requires at least OS X 10.8.5 to run (current OS X version is 10.11.6).

Upgrade your Mac's operating system, if possible, and in the future don't let it get so far behind.

Upgrade to OS X El Capitan - Apple Support

Also note the next major Mac operating system upgrade, MacOS Sierra, will be available on Sept. 20.
