I'm willing to bet it was a friend playing a prank. It could have also been a screenshot set as the wallpaper that possibly contributed to the effect in some way.

Do you have your computer set to turn on at a certain time? It's not possible to send a remote command to a computer that is truly powered off without using special network cards d…

Oh wait, I thought of something else, do you have your computer set to turn back on after a power loss? If so, maybe you had a power outage? I think if the machine is already off w…

Thanks for the replies. root is enabled on my computer and it was scheduled to start up everyday at 7:30am. The door to my room was locked so no one had physical access to my co…

The root account is an account of its own, so you can change that password any way you can change the password on your regular account when logged in. You can also use the "passwd"…

In /Applications/Utilities, open Netinfo Manager. Under the Security tab on my system, there are three headings: Authenticate Change Root password... Enable Root User I suspect t…

Hmmmmm. You don't have Patchlink installed on your system do you? A nasty (potentially) bug has been discovered recently where Patchlink spawns a Finder process as root, giving an…

No patchlink installed. I've now changed my root password and main user account passwords. Filevault is also enabled. Not sure what else I could do to secure my system in case t…

I came across some .exe files which belong to Photoshop. Spotlight indicates they have something to do with droplets, is this normal? I thought .exe files were found in Windows onl…

.exe files will only run on windows, not on OS X.

The droplets from Photoshop are indeed .exe's and run fine in OS X; however, they are more "cross-platform" scripts as you can pass them between Mac and PC's without issues.

They're scripts for Photoshop. If you right-click an image in the Finder and go to "Open With...", you'll be presented with those various scripts to do whatever it says they do to…

Hi, I'm new to macs and I need to know if there are any decent p2p softwares for mac users (not bit torrent, but something that uses eMule and gNutella like "shareaza"). Also sh…

P2P software (Gnutella, FastTrack, etc. networks): Acquisition, Xfactor, Poisoned, umm... there are other fine alternatives too. Search MacUpdate for "p2p" or perhaps a specific ne…

acquisiition works great for me! Limewire : destroyed my old dell (eww), and a friend swears his powerbook started falling apart since he started using limewire aswell

Something got screwed up with my iDisk and I can't fix it. Everytime the finder tries to access the iDisk I get the spinning beach ball of death forever. That includes shutting o…

It sounds as though your local iDisk image is corrupted and the Finder is stalling while trying to mount it. Try turning off iDisk synching altogether (not just switching off autom…

Just ran into something really annoying. Illustrator CS: We have a user that all of a sudden logged in as that user, Option-Click an image or text box will not copy anymore along w…

Every user can have their own preferences, keyboard shortcuts, etc. She probably just needs to set that up properly. Though the shift-resize issue is strange. Might try rebuilding …

Hello, I have two macs, an older imac downstairs and a newer imac upstairs. Downstairs I have a speaker system (not connected to the imac, but connnected to an airport express ba…

You MUST have something to connect to the downstairs machine. You can do it wirelessly, or wired, or a combination of both. I think the Express will support you. Read the manual…

Thanks Glen, Do you mean I need a wireless adapter for the downstairs Mac? I will have an ethernet bridge to get it onto the wireless network. What I'm wondering is if the netwo…

The ethernet bridge will work well for you; I like these a lot more than USB devices because they tend to be better implemented (read: ethernet is a real standard you can't fudge),…

Ok, thanks again Glen, I'lll give it a go and see what happens. I've done this same thing wired, just wondering if it works the same way wirelessly. Thanks again

The point of wireless is that it should be the same as wired, except without the clutter. It should look and work just like a wired network, only without the wires.
