Intel iMac Sleeps When it Shouldn't; Security Question

Message #1 - Posted 2006/10/30 - Davoud

1. My new 24" iMac sleeps after perhaps 15 minutes of inactivity even though it is set to never sleep. Advice?

2. A friend /finally/ moved from OS 8 to a new Mac. I was showing him (on my iMac) how to set up additional user accounts. In the process we set up a /standard/ account in his name. To my surprise, when he logged in he could see and use documents in my home folder. He had access to /all/ System Preferences and could install software. What gives?

Thanks,

Davoud

Could be set to dim the display ('separate timing for display sleep' in the same pref pane)

Your iMac has been hacked and a rootkit was installed so that all users are created with admin access.

Or your iMac is the one magic iMac where anyone's wish is their command.

Or your iMac has had the sudoer's file twiddled with.

A. What makes you think it is going to sleep?

B. Are you sure it's not that the screen saver is activating?

C. When it does this, how do you wake it up?

D. Which specific documents could he see and use in your home folder?

E. What do you mean by "access to all System Preferences"? Any user can open and view all System Preferences - but only administrators can *make changes* to _protected_ System Preferences.

Jolly Roger:

A. What makes you think it is going to sleep?

The pulsating "sleep" lamp on the front panel -- which is off when the computer is awake -- and 20+ years as a Mac user.

B. Are you sure it's not that the screen saver is activating?

Yep.

C. When it does this, how do you wake it up?

In my usual fashion -- tap the space bar or move the mouse.

D. Which specific documents could he see and use in your home folder?

Any and all. He should not have been able to access my home folder in any way.

E. What do you mean by "access to all System Preferences"?

I mean that he could do anything he wanted with any Preference Pane /except/ that he couldn't delete or modify his own account or my administrator account.

Something is seriously amuck with your system then.

That's "amok" and it means "in a homicidal frenzy."

While I am concerned that my Mac may have a glitch, I have seen no signs of malevolent behavior.

The default setting for Mac OS X allows any user read-only access to all files at the top level of your home folder, and to your Public and Sites folders, but not into the other standard folders (Desktop, Documents, Library, Movies, Music, Pictures). The only folder writeable by other users is ~/Public/Drop Box.

If you create other folders within your home folder, they default to having the same permissions as Public and Sites, i.e. read-only access to other users.

Any files you create in your home folder will default to the same read-only access.

The same goes for sub-folders, but the permissions on Desktop, Documents, etc. prevent other users from getting in the front door.

Ah - thanks for the kind correction. Now I'll try to commit that to my limited memory! : )

Seriously awry would be even better.
