The bigger concern probably isn't who you browser is contacting but instead rogue 
process's. If you see "Nefarious Application That Steals Your Identity" or some 
other app you don't recognize connecting to amazonaws or akama that is when you 
need to worry. Of course this requires becoming familiar with the names of normal 
system process' because at first they might seem to be unknown. In this regard 
Google is your friend, when I see a process that I haven't seen before, I look it 
up first and so far every time there have been other people asking about the same 
process's.


That's not to say that Safari can't be made to do bad things, but it's not very 
likely.

Almost certainly, given that this is a G5 iMac, it's bad caps in the power 
supply and/or logic board.



Plenty of instructions for the DIY-er and services to do it for you.

Power Mac G5 “Late 2005” Dual-Core cpu-version

[Mac User #330250]

Hi!
Happy New Year!


Would someone with a Power Mac G5 “Late 2005” model be so kind as to tell me 
the cpu-version of the PowerPC 970MP processor?

Start Terminal, execute the following:
ioreg -l | grep "cpu-version"


Thanks in advance!
Andreas  aka  Mac User #330250

iMac G5 won't power on

[faithie999]

a friend gave me a dead iMac 17" G5 iSight.  the symptom is:
when i push the power button, the pilot light comes on for about a
second, then the fan comes on at full speed, then about a second later
the pilot light and the fan turn off.  the screen never lights up and
there is no startup chime.  i've tried resetting SMU by unplugging,
then replugging while depressing the power button, then releasing and
re-pushing the power button.  same behavior as described above.

any ideas on how to troubleshoot this?  i did some googling, and there
is a link to an apple support doc for this problem for a non-isight
model (describes taking rear cover off, which clearly can't be done
with the isight model) but nothing other than uninformed speculation
on message boards about the isight G5.  i have dissassembled it and
looked for power supply diagnostic LED's but if they are there they're
not obvious.

thanks in advance for any ideas

Bruce covered it pretty well.

My complaint is these complex JavaScripts that many sites are using 
these days, to display BS from twitter, comment tracking services, 
etc.  Very annoying.  Some are so bad that Safari complains that the 
scripts are chewing up too much.  Of course, if you block them then 
things start breaking...

This is a generalized case of rule #3 of computer security:

Rule 1) If you let the bad guy physically access your computer...it's not your 
computer anymore.
Rule 2) If you let the bad guy run programs on your computer...it's not your 
computer anymore.
Rule 3) If you run programs FOR the bad guy on your computer...it's not your 
computer anymore.

If you agree to run software that can access your CPU for various purposes, 
then yes they can. If they start doing this too surreptitiously, they'll get 
caught pretty quickly (witness Sony's horrible 'rootkit' DRM experience of a 
few years ago) Generally speaking the only folks who do this are the ones who 
say they're doing it: Folding@Home, SETI@Home, etc. Dropbox has user-level 
access to your system, there's a Dropbox daemon running on all  my Macs right 
now. It has to, to work correctly.

All said, scrutinizing your network communications without knowing what's 
really going on is an exercise in futility and fear. As Dan pointed out...often 
what looks like a sinister connection is actually a completely normal part of 
the modern internet experience. As dc discovered, Pandora can't do the kinds of 
things it does without a lot of communications to and fro. If you don't like 
it, don't use the service...

It helps when people are aware of what goes on, but if they aren't educated 
about what is and isn't scary, you get the things like the periodic freakout on 
the nightly news when they rediscover 'cookies' again and suddenly 'cookies' 
are the scariest threat imaginable.

(and then I get emails and phone calls from folks here at the U about how our 
internal web tools aren't working "is there something wrong with the 
internet?"...no, you disabled cookies, again, didn't you, because some gasbag 
on the news did a segment on it? )

The best way to do this is to use these privacy tools as a guide to seeing what 
normally goes on with your computer. Don't assume that your system is horribly 
hacked and they're siphoning off all your data to their secret underground 
lairs. It's like the system log. If you look at your system log at boot time 
you'll see dozens of things that look like problems, this thing failed to load, 
that thing was disabled, this process was killed, the other file wasn't found. 
Uneducated you'll come away thinking your system is on the brink of collapse. 
Knowing that  all of these events are normal (if you're not having problems 
with your computer, that is) puts all of this info in a different light.

Learning what's 'normal' is the key. You don't need to know what things are, 
just that, 'this is new, I haven't seen that before'.

Or don't learn this, and learn to stop worrying...the only security things a 
Mac user really ever has to do is turn off the 'Open "safe" files after 
downloading' preference in Safari, and recognize that a web site telling you 
your Mac is infected with a virus is lying to you and is trying to infect your 
Mac. 

That's it. 

OS X is a remarkably robust, hard-to-break operating system that's quite 
secure; out of the box there's nothing for an intruder to attack, because you 
have no outward-facing services running.

Moreover given that probably 80-90% of you are connecting through home networks 
behind a NAT-enabled router (meaning that outside connections couldn't find 
their way to your system if they tried, even if you were running everything 
wide open) and that 99.999% of all the malware in the world, and 100% of 
all the malware 'in the wild" is aimed at Windows...you don't really have 
anything to worry about. 

Relax, have some champagne, enjoy the New Year, and go forth and have fun with 
your mac or your family and friends or your dogs and cats (or iguanas, hamsters 
and fancy rats if that's your gig!)...and you'll excuse me, since a canine 
member of the family keeps jostling my elbow and dropping her tennis ball on 
the floor suggestively, I believe I'll just go and do that!

Thanks for the rational explanation Dan, for a Psychoceramic Emeritus
you are remarkably non-paranoid! I was mainly concerned because these
were outgoing, not incoming, activities. When I shut down Pandora and
cleared all website data most of the activity stopped. That makes
sense to me, Pandora is constantly running pop-up ads and collecting
data about the music I select. Even with just this page open I still
get 6 different connections (Activity Monitor shows only this page).
So I guess I'll try to be calm about 1.amazonaws.com,
akamaitechnologies.com, iad04s01-in, etc.  Maybe a little medicinal
champagne is in order for me this evening.
