Author Topic: Question on kernel panic and ACLs (Read 4722 times)

Finally got up and running with Leopard on my new iMac. A few glitches here and there- such as "insufficient privileges" to install, my G5 which was attached via target mode now being renamed, and G5 info sometimes popping up in various apps. However, both printers and scanner are operational, and I am doing fine. Till today. Was on Norton's site to download Antivirus 11, and the machine froze with a message I needed to restart, that OSX had quit. Couldn't restart - everything was frozen, so I had to use the power button to shut down and start up.

Decided to repair permissions, and got an extraordinary list of items starting with "ACL not expected". What does this mean? It all referred to library items. I have not run it again to see if the list is still there. I never had a kernel panic before, don't know what caused it, and don't know what to look for to avoid this again.

Hoping some of you can address these issues and steer me in the right direction. And...while I'm at it, since SuperDuper is still not functional for Leopard, what do I use to back up to my firewire? Last time I tried Time Machine, I got a message that there was not enough room on the disk- and there was. I have not tried it since.

I am copying and pasting some of what appeared on disk utility after permission repair was complete. D I need to do anything about this?

Personally, I wouldn't recommend using ANY Norton product - from most reports I've read they cause nothing but headaches. I've seen Norton Antivirus described as the only piece of "malware" available for OSX.

I don't run any antivirus software on any of our 6 Macs, but if I did, I'd use the free ClamAVX. http://www.clamxav.com Why bother enriching Symantec's coffers when there still are NO actual, real, live, nasty, damage-causing viruses for OS X. And that's after more than 7 years.

Have you updated Leopard to 10.5.1? Apparently that will cure the "ACL not expected" messages.

For backups - Carbon Copy Cloner will work with Leopard.

Have CCC. Thanks.

Maybe I'm missing it... but, what's an ACL (in the computer world)?

Paddy · « **Reply #5 on:** December 12, 2007, 08:06:17 AM »

Explanation here, Gregg:

http://www.bresink.com/osx/193281/Docs-en/ACL.html

QUOTE

Access Control Lists, abbreviated ACLs, are an additional method to grant specific permissions to certain users. Apple introduced this technology in Mac OS X 10.4 "Tiger", but it can be found in other Unix® operating systems and Microsoft® Windows as well. ACLs are a supplement to the existing POSIX permissions, so you don't necessarily need to use ACLs. The conventional rules for access rights still apply, but some optional new rules can be added.

Read on at link provided for complete explanation.

A new one for me too.

I guess for legal reasons, Apple can't publish the warnings about using Norton.

Paddy, great! ... a definition of an acronym that uses an undefined acronmym! Gotta love it!

Thanks for sharing your research. I'm just the curious type, but not too industrious when it comes to such things.

Nope...

The Institute of Electrical and Electronics Engineers or IEEE (pronounced as eye-triple-e) is an international non-profit, professional organization for the advancement of technology related to electricity. It has the most members of any technical professional organization in the world, with more than 360,000 members in around 175 countries.

The circle is broken.

The kernel panic you experienced is quite common to anyone who uses Norton Antivirus.

Because there are no (that's right, zero) viruses for Macs in the wild, antivirus software is a waste of time and money; software vendors count on people's fear to make them open their wallets and part with cash. Norton Antivirus works to protect your Mac against viruses exactly as well as it works against werewolves, zombies, and vampires.

However, on top of that, there are many well-known, documented bugs in Norton Antivirus. These bugs can cause crashes, freezes, kernel panics, problems with network file copies, corruption of files, and other problems on your Mac. Norton Antivirus is poorly maintained, and on several occasions Symantec has released flawed update files that cause it to wrongly identify harmless files as "viruses." Last year, for example, they released a virus update that caused Norton Antivirus to say that a critical Mac OS system file was a "virus," and people who tried to clean up this "virus" ended up crashing their computers.

And it gets worse. The uninstaller that Symantec provides to remove Norton Antivirus doesn't work.

There is a script you can find here that will remove Norton Antivirus from your computer.

I agree with Tacit.
But.......in some cases, others require you to have anti-virus software, they will not communicate via email without verification that it is in use, so we use Sophos to satisfy those who insist that we do.

In the years that I have used Sophos I have had no issues with viruses. (there have been No Viruses) The program sits ideally by, as does ClamX a free anti-virus program for Mac.

I would cleans from my Mac All things Norton/Symantec.

Don't see version for Leopard on their site.
