I'm running a G4, silver front, 1.0 mhz, 2 gig RAM.\n\nI installed Leopard over 10.3.9 and everything was going fine for a a\nfew days. Then, things began to slow down, with the spinning beachball\ngoing on for about 30 seconds every time I tried to do anything.\n\nI booted from another internal HD and used Disk Utility to repair the\ndirectory. The primary HD came up as "Okay". Then I repaired the\npermissions, and a bunch needed and received repair, except for the\nfirst item in the list. The report came out like this:\n\nWarning: SUID file "System/Library/CoreServices/RemoteManagement/\nARDAgent.app/Contents/MacOS/ARDAgent" has been modified and will not\nbe repaired.\n\nI located this ARDAgent file, and sure enough it's there, but I have\nno idea what it does, or how it got "modified." I decided to try\nreinstalling Leopard. The install crashed in the middle of\ninstallation. I'm working now from a duplicate copy of my internal HD\nthat I backed up with Retrospect to an external HD, thankfully.\n\nAnyone have any idea what's going on and what to do about it?\n\nThanks!
