The Wilderness Guardians - OSRS Clan - PvP, PvM and More - OSRS Mobile Clans

Figure I try asking here in case anyone knows:

I recently got a used power Mac (I think g4) and am having difficulty reformatting it. 

I have tried doing command + R on reboot, but nothing happens.  I am not sure what version of Mac os x I have, but I think it might be snow leapord.  In that case, I might need the install disk...which I also don't have.

I also do not know the existing user login.  So I am now with a useless machine that I can't use.  Also, macs are very foreign to me, so I'm a bit lost.

In worst case, I am considering loading linux onto it.

Any ideas?   

Hello WG, especially to the older guardians who might remember us!

Valdremia and I will be getting RS members for December to enjoy during the holiday season.  We hope to be able to attend some events, so if you know of anything interesting happening next month, please send us an invite :)
