Friend joins my server and doesn't have any tools!

I usually play Gmod on my friend’s computer (a local server on a Mac mini running OSX 10.6.7), but it’s slow and crappy so it usually lags a lot. So I asked him to come on my server (local server also on a 8gb RAM Windows 7 pc). Whenever he joins, he has no tools, but he has his prop menu so he can spawn things. But he can’t modify ragdolls or use thrusters or anything. Can someone give us a hand please? Thanks :slight_smile:
