Setting Up Mac OS X for a Teenage Coffeehouse?
WCityMike writes "I plan to donate a grape iMac to a local church-run non-profit coffeehouse for teenagers, and would like to give it to them appropriately set up for the atmosphere it'll be in. I'm seeking advice on a number of fronts - what freeware or shareware applications would be good for such an environment? Should visitors be allowed to have their own accounts (presumably created by the administrator), or should I just set up one 'student' account and one 'administrator' account? If the latter, is there a way to prevent students from saving things on the hard drive (thus forcing them to use a diskette and/or the CD drive?), and/or a 'Simple Finder' interface extant for OS X? Is there existing software that makes this easier or more configurable, or is it all inside the OS? I'm fairly familiar with Mac OS X, but have never needed to run anything outside a single-user environment."
I would set up an admin account and several "template" accounts based on different types of usage such as "internet only," "power user," etc. You get the idea.
I would then train someone within the organization on how to setup, modify, and maintain the accounts (unless that is going to be you.).
Once again, your generosity of money and time is commendable.
Happy Trails!

http://www.macosxhints.com/ is a great place to start looking for the misc answers you may need.
Image it first, because no matter what you do, someone will somehow find a way to trash it or release a virus or the hard drive will crash or lightning will strike it or....

This pdf link. It tells you how to restore a dummy user's home directory after each login (Its for OSX, not sure if the grape can handle that or not).
Aside from some software tweaking and installation, this should really help your setup.
You're essentially looking to do the same thing many, many others have already done, and are doing every day, with Mac OS X in public lab-type environments. Do yourself a favor and visit
...particularly the documentation section.

if they're anything like the teenagers I grew up with, trust them with nothing and they'll be needing lots of porn.
Don't tell the church that your Mac OS X box will be full of daemons. They will get exorcized over it!
Strange women lying in ponds distributing swords is no basis for a system of government.
It's common in the Mac community to give the "Flavor" instead of the full configuration. My guess is he wanted to give an estimation of the configuration involved, and that is good for me. for a Mac user "grape"= "iMac CRT 266 or 333, 6Mb VRAM, 6Gb HD, USB1, no Firewire", so yes I think "grape" is relevant information. On a grape iMac, you could run panther, and there is a "Simple Finder" equivalent on 10.3
I have never used it. But here is an application to make it into a kiosk. Good Luck.

I have basically done the same thing with 4 iMacs (233Mhz 320mb RAM)I donated to my local public library. They are used as internet/office/iTunes/AIM stations in a young adults room (grades 4-9). They are currently running 10.3.4 with shadow killer (a MUST for older machines running 10.x. Found at http://www.haxies.com ).
I set mine up with an Admin account (named staff) and a simple finder account (named student). Just go into the UserAccount section of system preferences, set the account you want limited to "simple finder" and limit what else you don't want them to have access to. It is also handy to give them a little bit of space to use for autosave in office and such (or scratch disks in Photoshop).
I have attempted to do similar limitations for the Windows XP computers in the adult section of the library (Using XP Security Console plug-in by Doug Knox), but have had nowhere near the success as I have had with the Macs. They have been running for a year now with ZERO down time.
Good Luck!!
You are not alone. This is not normal. None of this is normal.
Take a tip from an administrator in a public school system:
Pick up a copy a copy of DriveShield for the Mac, and allow the students to do whatever they wish to it.
DriveShield is a driver that sits between the hard drive and the OS. Any writes made to the hard drive are redirected into a sratch area of the hard drive, and thus don't stick around for the next reboot. The machine will be back in the state it was in when it was locked on every reboot.
I've tested it by even booting off a System CD and reformatting the drive... on the next reboot it comes right back to how you expect!
The philosophy used to be to lock the machine down as tight as possible to prevent the users from making any changes to it. (Restricted Finder, Windows Policies, etc.) Products like DriveShield (DeepFreeze is another one) work differently -- they don't lock down the machine to the user at all, they just prevent any changes from sticking across a reboot.
Protect the machine with DriveShield (or something similar), and have all the kids log in as the admin. Quick and easy to do, and the kids don't have to be restricted to a limited set of options on the computer!
We've been using this technique in several of our schools now (only in the open labs, mind you -- not the staff computers!), and the only support calls we now recieve in those labs is for hardware problems, not software.

Disclaimer: I didn't use OSX before Panther, so this may not apply to the version you have.
Simple Finder is an incredible pain in the ass and confuses the hell out of Windows users. My girlfriend is largely computer-illiterate (she's memorized the motions and screen locations needed to operate Office, but not much else). I set up a limited account on my iBook because she couldn't seen to get to the web browser without dragging my Terminal icon off the dock. But that's a diatribe for another time.
I set up Simple Finder. No good. I can't blame her -- I couldn't really figure out how to get much actual work done with it.
In the end, I've been using a straight Limited Account for my Guest acct on the laptop, with much success. MacOS X already does a good job of keeping users out of one anothers' stuff, by properly setting homedir modes and whatnot. I've been working for a couple of weeks to bypass the Limited Account limitations, without luck. If you declare that the user cannot run a particular application, I haven't figured out a way around it that doesn't require admin.
However, unlike my experience with Windows, a limited account on OS X is still quite usable. Programs don't automatically expect to have root, and aren't able to sneak off and get it without asking (*cough*WinIE*cough*). If the need arises, the Auth Services password-dialog provides a way for an employee to work magic if necessary.
My recommendations, therefore:
1. Set up a 'Managed' account for the coffee people. Don't do per-user accounts unless you want to set up an LDAP server to handle it; cloning account settings on a single-user MacOS X system is a bitch. Retain an admin account for the employees.
2. Whitelist, not blacklist, the apps the user can run. Give them access to Safari and whatever else. Don't let them dork with the dock, etc. Specifically allowing access to a handful of apps will prevent them from firing up a new one from a USB key. Because they'll try. Oh, they'll try.
3. Unfortunately, I'd recommend against giving them iChat. iChat, unlike Windows AIM and GAIM, doesn't give you an easy way to switch accounts -- which is a must-have on a public terminal.
4. Lock down the keychain. Set Safari to not save passwords. Locking the keychain (with some known but non-obvious password) will prevent users from saving new items into it. This is a good thing.
5. Giving access to iTunes puts you in an interesting legal gray area. Like iChat, it provides no easy way to change accounts (in terms of iTMS). It also enables users to rip CDs. This may not be a good idea.
6. Unfortunately, OS X does not provide disk quotas, as far as I can tell (please, if someone knows different, clue me in!). The support is there in the filesystem, but there doesn't appear to be a UI. Keep this in mind.
7. As admin, periodically use Repair Permissions in Disk Utility to check for anything that's become accessible to the peons. More importantly, do this after you're done with the initial software install -- you'd be amazed at how much commercial software starts out world-writeable. (Bad Adobe.)
Good luck!
