I would take it to an Apple specialist and have them run a hardware test on it. If it has a hardware failure then Apple usually does a decent job of replacing it. I know when my old G3 tower's firewire ports stopped working and it was out of Warranty, Apple went ahead and replaced the board for a $50 cost. (Basically shipping)

Of course it's not! It's not a Linux OS!

He has been known to bash anything not Linux. He's very egotistical ya know.

I'd use Linux if it was user friendly and had major application support.

But so far, the only .nix that has that is OS X.

You didn't read what I said. I said yes, they have found vulnerabilities.
But this hasn't effected ONE Mac user yet. And no, it hasn't been a long time, and it's nowhere near the amount Windows has. And this has something to do with market share, AND something to do with Windows being more insecure than the Mac OS

"I am working with them (not only), and with loads of them, so i pretty much know what i am doing most of the time"

You are working with them what? Be specific when you write.

" and saying that there is an operating system for which there is no malware is just bollocks. there is malware for unix, linux, osx and windows. and lots of windows malware because so many people use it."

The maleware problem Windows has has to do with it's usage AND MSs crappy coding and "no care" policy on such things. As Gates has said himself. I have never seen CRAP about OS X maleware. Why isn't there any removers for such things for OS X then? Where are they at?

"Other, less known OSes are way less secure than even XP or 98 (oh and there are big fat reasons for which I dont think that vista is a good OS just yet) but since no one uses it, there is just little malware, and the stuff that does exist, is mainly there for testing purposes."

Again, I said that it didn't exist in the public. No one had been bit by it. I didn't say it didn't exist at all.

No OS X computer has been infected by it. And you can say that is because it has small numbers, but that would be dishonest. Because back in the classic days there were viruses that got around and spread with a even smaller user base.

Yes, one of the reasons Windows DOES get viruses more often is because it's the one used the most. But that isn't the only reason. That's not even the main reason.

The OSX filesystem is not the best as was so recently and not so subtly pointed out by Linux Torvalds, and it sounds like that might be the problem... especially since you say re-installing Safari with Pacifist fixed it. I'd recommend at least running Tech Tool Pro or Disk Warrior on your drive before you go with a reformat. Heck, even give the bundled Disk Utility a go before you shell out for those utilities, it just isn't as thorough.

Other, less known OSes are way less secure than even XP or 98 (oh and there are big fat reasons for which I dont think that vista is a good OS just yet) but since no one uses it, there is just little malware, and the stuff that does exist, is mainly there for testing purposes.

Also, running the combo updater would be the way to go. Tiger got more stable with each update, so updating to version 10.4.11 could fix alot of problems. I hope this helps.

My bad.

"no, macs are not resistant to malware like viruses and such. It’s just that everyone believes that, because Steve Jobs doesn’t do a god job in sharing information on vulnerabilities; OSX is full of them."

Yet no one knows of anyone that has gotten any viruses or malware using OS X since it's existence..

I think what you mean is, they have found (and quickly patched) vulnerabilities in OS X that they say someone might have been able to do something malicious, but it never has happened.

Then you say this

"The bigger the Mac-Sect grows, the more malware will be released for that operating system."

They would have to figure out a way to exploit it, and for it to actually spread first.

"The only reason, why Windows has so many viruses is not that it is so badly coded (all operating systems have their flaws) but that so so many people use it, i.e. the target group is simply bigger."

No, it's coding and MS leaving it's OS wide open IS a reason that it has so much problems.

Especially with quotes like this coming from Gates himself...

"If you can't make it good, at least make it look good."

"Since when has the world of computer software design been about what people want? This is a simple question of evolution. The day is quickly coming when every knee will bow down to a silicon fist, and you will all beg your binary gods for mercy."

"You see, antiquated ideas of kindness and generosity are simply bugs that must be programmed out of our world. And these cold, unfeeling machines will show us the way. "

"We're no longer in the days where everything is super well crafted. But at the heart of the programs that make it to the top, you'll find that the key internal code was done by a few people who really know what they were doing."

"I know not a single less irrelevant reason for an update than bugfixes. The reasons for updates are to present more new features."

Until recently, MS wasn't too concerned about bug fixes, or security.

I see Vista finally started using permissions the way SECURE computers are supposed to, and my comments about windows only covers XP and below, as I don't have any experience with Vista (My barely 2 year old Windows box wont run Vista.. But my 4 year old Mac runs 10.5 just fine.. )

I am just so tired of hearing FUD coming from both ends of the spectrum.

Do I think there will be vulnerabilities in OS X if it had a larger market share? Maybe. More than likely.

Do I think it would have as much problems as Windows has had? No. Their priorities are different than that of MS.

MS has people brainwashed into thinking that it's a COMMON thing to have to run such software (malware removers, virus scanners) constantly on a CONSUMER device. One should have to take a college course to learn to run and keep up a CONSUMER device.

Now am I saying that OS X is perfect and has no problems? Of course not. That would be silly and zealous. But it's years ahead of Windows right now as far as stability and features goes.

And I am no Apple fanboy. If I could use Linux for what I do, I would just because it's a cheaper alternative. If something better came out for what I do, I would be all over it in a second.

As of right now, there simply is none.

These are just tools people. No need to get emotionally attached to them to the point where you start making up FUD.

You should at least download and install the 'Mac OS X Update 10.4.7 Combo PPC' from apple.com. Or better: the 'Mac OS X 10.4.11 Combo Update (PPC)'.
A 'combo'-update includes all previous updates, so it's much better then separate updates.

Some of the early G4 Mac Minis came with 256MB of RAM, which is not really enough, especially for Leopard.

You could also run the "Apple Hardware Test" off of the CD to see if it is a hardware issue. Instructions are here for Intel (http://docs.info.apple.com/article.html?artnum=303081) but the same should work for PPC. The Apple Hardware Test is found on Disk 1 of your Mac Mini restore disks.

I have it for my PC, but I think it works for Mac as well.

You show me any evidence of a self-propagating worm or virus, along with corroborating evidence of its existence from a known, trusted, 3rd-party security specialist firm, one that installs itself without user-interaction or malicious physical access to the system and which is running unfettered in the wild, and I'll eat a box of rocks.

Oh, that's right:
THERE AREN'T ANY! If there were, it'd be some of the biggest computer-related news to come down the pike in years, and that news would be plastered EVERYWHERE, and EVERYONE would be yammering about it on every forum in existence.

Guess I'll be having a meatloaf sandwich for lunch.

I tried using that software, but it only made my screen gradually turn darker until I couldn't see anything. But everything was fine the next morning.

(I know it was a typo, but i had to. )

//hate mac's and their black turtleneck loving snobbery.

If you use AppleWorks a lot you should throw away the AppleWorks-folder in your Documents-folder. If that is too full it can really slow down AppleWorks. The next time you run it, it will create a new folder.

You can also check the Font Book application in your Applications-folder. It has an option nowadays to look for font conflicts.

For the basic troubleshooting I really like Applejack: very small download from versiontracker.com. Install it. Start your Mac with Command-S pressed. Type 'applejack auto restart' and press Return-button. It repairs your disk and permissions, clears caches, checks preferences, etc. It's the easiest way to solve a lot of problems.

I know that's a PC and you have a MAC, but at least you'll get an idea. Also while searching for that link I found another one you might want to read.

If you search around that website you may come across the answer, but I dont know I have a PC.

1. Do not blindly upgrade a poorly working computer. Unless an expert looks at your computer and tells you you need more RAM, it will likely be a waste of money. Same goes for Leopard. Why spend $300 on upgrades when a new Mini cost $600?

2. Test with another keyboard. Yes, it could simply be that yours is broken.

3. Run your Mac in Safe Mode. Complete power down. Start Button. Lean on the shift key until the gray apple appears.

If the typing works in Safe Mode, then the problem is with software and not the OS or your hardware.

4. If it is software, uninstall everything that you do not use.

5. You should be backing up your computer every day no matter what problems you are or are not having. If you cannot figure out how to do it with the equipment at hand, buy an external hard drive that comes bundled with software.

6. Find a tech. If your career depends on your computer, it is fatally foolish to depend on advice from forums for your support.

That said, I have had similar problems with my Mac Mini. I found that it was just underpowered, so I upgraded the RAM, and that fixed it for the most part. I still have trouble every now and then (for example, Safari has been having trouble with flash for a while), but for the most part it works fairly well.
