What could change the disk permissions?

When I talked to an advisor from Apple Care, he asked me to do "verify disk permissions" under the First Aid tab of the Disk Utility software. These are the various read/write/execute permissions of Unix file systems. To my surprise, there were about 7-8 files' permissoins were changed.
What could change the file permissions? Some of the files are related to Safari which I don't use at all.
The reason I contacted Apple Care is that my Mac Pro lost the sound output after I woke it up from the sleep mode. There was no sound output from iTunes or YouTube vidoes. That is why I contacted AppleCare. After I did a "repair disk permissions", the sound output returns.

You are looking at the report by Disk Utility as it repaired permissions on files based on the permissions database of your OS X installation. If those permissions differ from the file's actual settings, then Disk Utility changes them to conform with the database's permissions.
In most cases the reported information you see in Disk Utility are false positives that result in no real change but just an information message that you can ignore.
In your case it's probable that one of the apps you had open made an improper write to the disk when you put the computer to sleep, and that ended up changing some file permissions that should not have been changed.

What could change the Computer ID used for the licenses in NI License Manager?

at our customer site we originally set up our software which uses the Vision Run-Time and Vision Acquisition Software. We purchased a license for the PC and it was installed. It has been running since July. but today the customer started getting errors asking for the license. using NI license manager we see "Status: Activated for a different computer"
looking further we now see a different "Computer ID" code I have original screen shots of when I originally applied the license so I know the Computer ID was not a typo.
The customer says no one has swapped out the PC's, but is currently looking to see if any other work was done.
Has anyone expirenced this before?
Solved!

I hope your problem was solved by now.
If not, is your customer using any VPN software?
VPN software creates virtual MAC address, and somehow NI License Manager will use that for computer ID.
A known case is that VPN software by Juniper Networks will randomly create a virtual MAC address
every time the computer reboots. This will screw up NI License Manager because the computer ID will be different every time
computer reboots.
A workaround is to ask NI for an activation code based on computer ID that is generated from your hard drive.
With this, unless you change your harddriver or format it, it will keep the same computer ID.
That is exactly what my problem was. I ended up getting a computer ID based on the harddrive. The thing is that when performing the "automated" activation, it uses the computer ID from the MAC address. So I have to activate over email, change the file so that it uses my harddrive based computer ID, send it, apply the received codes. It is kind of a pain, but not that bad.

What could change the settings on our network?

I have a little network populated by two printers, a NAS and 3 CPU's (two Macs and a Laptop running XP).
Recently the laptop started misbehaving and while it is better now it still is a little odd. However, this question concerns something I discovered along the way and I doubt that the laptop is a player here.
The IP settings are fairly typical. IP is 192.168.0.X Subnet mask is 255.255.255.0 Most items are DHCP but I keep the NAS and one printer at fixed addresses so I can reliably address their web based GUI's via a browser pointed to http://192.168.0.200 for example. The router/modem is at 192.168.0.1.
Here is the oddity: One recent day I found that the printer and the NAS had changed their IP addresses to 192.168.1.200. How did that 3rd octet switch from 0 to 1? I did not do this. Can network citizens change their addresses, jumping out of the LAN?
Bob V

Some IAPs do provide a fixed IP address, but many change them periodically: this doesn't affect your normal use as the change is usually seamless: it's done to stop you running a web server (and thus using a lot more bandwidth).
However the OP isn't in fact dealing with IP numbers issued by his ISP. He has a router, which is being issued with an IP number by his ISP, but which is issuing its own numbers to his local network. Numbers starting 192 are only ever issued by local equipment, and thus are invisible from the internet side of the router they have to be, since thousands of people are using the same 192... numbers).
Since he has set his printer etc. to fixed IP numbers they should stay the same, though obviously the computers, which are using DHCP, may change from time to time. If they are changing it's a matter with the router: it has nothing whatever to do with his ISP.

iDVD is not involved in the process at all.
What you want to do is create a data disk on a DVD. That's done by inserting a blank DVD disc in the optical drive, Option+drag the files you want to backup onto the disc icon on the desktop and then drag that icon to the Trash bin in the dock which turns into the Burn feature.
Try that (the Option+drag and see if you can get your files to burn.

HT1338 I have version Mac OS X 10.5.8. I no longer get software updates. What could be the problem?

I have version Mac OS X 10.5.8. I no longer get software updates. What could be the problem?

No problem. You have to pay for the next upgrades, just like you paid for the last one.
Upgrade Paths to Snow Leopard, Lion, and/or Mountain Lion
You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
Upgrading to Snow Leopard
You can purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard — Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
     Snow Leopard General Requirements
       1. Mac computer with an Intel processor
       2. 1GB of memory
       3. 5GB of available disk space
       4. DVD drive for installation
       5. Some features require a compatible Internet service provider;
           fees may apply.
       6. Some features require Apple’s iCloud services; fees and
           terms apply.
Upgrading to Lion
If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
You can purchase Lion by contacting Customer Service: Contacting Apple for support and service — this includes international calling numbers. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
     Lion System Requirements
       1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
           or Xeon processor
       2. 2GB of memory
       3. OS X v10.6.6 or later (v10.6.8 recommended)
       4. 7GB of available space
       5. Some features require an Apple ID; terms apply.
Upgrading to Mountain Lion
To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
     OS X Mountain Lion — System Requirements
       Macs that can be upgraded to OS X Mountain Lion
         1. iMac (Mid 2007 or newer) — Model Identifier 7,1 or later
         2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) —
             Model Identifier 5,1 or later
         3. MacBook Pro (Mid/Late 2007 or newer) — Model Identifier 3,1 or later
         4. MacBook Air (Late 2008 or newer) — Model Identifier 2,1 or later
         5. Mac mini (Early 2009 or newer) — Model Identifier 3,1 or later
         6. Mac Pro (Early 2008 or newer) — Model Identifier 3,1 or later
         7. Xserve (Early 2009) — Model Identifier 3,1 or later
To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.
Are my applications compatible?
         See App Compatibility Table — RoaringApps.

Wifi on my mac OS X 10.9 running marvericks its saying no hardware installed, what could be the solution?

https://discussions.apple.com/discussion/create.jspa?containerType=14&redirectUR L=%2Findex.jspa&question=true&containerID=2998&subject=wifi on my mac its saying no hardware installed, what could be the solution

There are a number of possible reasons for that message, including defective hardware that only Apple will be able to fix. The steps you can perform yourself are as follows:
1.
Perform an SMC reset. Read all the steps.
Before Resetting the SMC
Try each of the following steps in this order before you reset the SMC. Test the issue after completing each troubleshooting step to determine if the issue still occurs.
Press Command + Option + Escape to force quit any application that is not responding.
Put your Mac to sleep by choosing the Apple () menu from the upper-left menu bar and then choosing Sleep. Wake the computer after it has gone to sleep.
Restart your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Restart.
Shut down your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Shut Down.
Resetting the SMC on portables with a battery you should not remove on your own
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if it's not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time. The power adapter indicator light may cycle off / on once.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Resetting the SMC for Mac Pro, Intel-based iMac, Intel-based Mac mini, or Intel-based Xserve
Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.
2.
NVRAM reset:
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
After resetting NVRAM or PRAM, you may need to reconfigure your settings for speaker volume, screen resolution, startup disk selection, and time zone information. If issues persist, your Mac's logic board battery (not a portable Mac's rechargeable battery) may need to be replaced. The logic board battery helps retain NVRAM/PRAM settings when your computer is shut down. You can take your Mac to a Mac Genius or Apple Authorized Service Provider to replace the battery on the logic board.

You should boot from the Installer DVD by holding down the C key during start up until the Apple logo and spinning cog wheel appears. Allow plenty of time for the installer to appear - it can take several minutes when booting from a disc.
I suggest not doing this unless the Apple recommended method (starting by double-clicking on the
Install Mac OS X icon while booted up normally) fails.
There are several reasons for this:
The Apple method performs a check of the DVD's integrity before starting up from it. This can't be done if you start up directly from the DVD.
The Apple method "phones home" using the current OS's network settings to check for updates to the incompatible items database included on the DVD & writes a lot of pre-install data (the 'Mac OS X Install Data' stuff) to the HD before restarting automatically from the DVD to finish the installation. This may not work as expected if you start up directly from the DVD.
The pre-install data on the HD speeds up the installation process (because running the OS from the HD to build the data is faster than doing that while running from a DVD).
The Apple method makes it possible to "gracefully" cancel the installation before the automatic restart occurs without leaving the existing OS on the HD in a corrupted, "half-installed" state unable to restart the Mac. This sometimes happens if the installation process hangs & one has to force-restart the Mac to recover. As long as this occurs during the "pre-install phase" before the restart, the existing OS should remain untouched & intact.
Also note that the Snow Leopard installer is quite a bit more sophisticated than the previous ones like for Leopard or Tiger. It automatically performs the equivalent of Disk Utility's Verify Disk step before beginning the installation & performs more checks during the installation process (including checking the pre-install data for errors). It is usually not necessary to remove the "Mac OS X Install Data" folder after a failed installation, which may just cause the process to take longer on subsequent attempts, but if nothing else helps it is certainly something worth trying.

Hi,
Is this failing with Error 20 ?
Sometimes in a the router or modem if you use Port Forwarding then you are your Buddy may be missing the Screen Sharing Port.
The Screen Sharing part uses a different port to the Audio port.
As the port for Audio (And therefore Video) are known and can be port Forwarded it is the random Screen Sharing port that can be the problem.
iChat 3 info http://support.apple.com/kb/HT1507 that includes Bonjour and Jabber info
iChat 4 info http://support.apple.com/kb/HT2282
If you are not using (or your Buddy) UPnP then I would change the method of opening the port to that.

Yes, I think most of us do understand what open source software is. It sounds as if you don't. Here's some information:
Open-source software (OSS) is computer software that is available in source code form: the source code and certain other rights normally reserved forcopyright holders are provided under an open-source license that permits users to study, change, improve and at times also to distribute the software.
Open source software is very often developed in a public, collaborative manner. Open-source software is the most prominent example of open-sourcedevelopment and often compared to (technically defined) user-generated content or (legally defined) open content movements.

Install Woe - What could be the problem?

Hi all,
I'm hoping someone can help me.
Got a new Printer (Xerox Phaser 8560), and have been installing drivers all over the office, MacIntel and PPC computers, many and no problems until I went to install on my iMac PPC, which resulted in the installer program crashing right after it attempts to find the printer on the network. I tried installing as root user with the same result. I made sure permissions were rebuilt, but always the same installer crash.
To make a long story short, I reinstalled Leopard from scratch, and it's still doing the crash when I try to install the driver. On the new install, I did "transfer" over my settings from the previous install, so I guess that helps narrow it down. But what could be the problem here?
Suggestions gladly accepted.
Thanks, and so long for now, TOM

Hi,
I think I may be on to something. I had removed a program (System Preference Pane) called ABFR, A Better Finder Rename 7, which was for Tiger, but it got carried over into Leopard. After it caused a problem with iCal, I learned that it wasn't for Leopard, so I removed it.
When I went into the latest install of Leopard System Preferences, there it was, and when I tried to remove it with a control click, I got an error which said it couldn't be removed because of an error.
I had brought over the settings from the previous System and didn't realize it was going to bring that over somehow. Looks like a totally new Leopard install and a total rebuild from scratch is in order. I wrote an e-mail to the developer, but I have my doubts.
Those little programs that install those System extensions should have them all disabled by Apple when you do a major software update. I hadn't used that program for years, but there it was causing trouble, and now it might still be causing trouble.
FYI, Xerox recommends using the drivers from their site and not any drivers supplied by Apple, either Tiger or Leopard.
Thanks, and so long for now, TOM

On connecting to itunes or charger iPhone 5 beeping continously and I am unable see anything on display. In itunes I can see everything when I connect to computer. What could be the issue with my display and how to fix it.

My iphone power button is not working so today I decided to replace it, on opening few screws I was unable to continue as I was not able to open all the screws on the iphone. So far I had managed to disconnect display panel & battery only. So I decided to not to replace button myself and I closed it. After closing I am able to see iphone 5 connected to itunes and I can see all my data, however it continuesly beeping when connected to charger or computer. Also I do not see anything on display. Before opening the iphone everything was working fine now I can't see anything on screen.
I do not see any hardware demage or anything like that, can anyone suggest what could be the problem?
Please help

Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new). Try each of these in order until the issue is resolved.
Everything that cames in the box is included in the 1year warranty, unfortunately you're just outside of that warranty. Regardless, if the above troubleshooting does not resolve, take the device to Apple and they can determine if the issue is the device, the charger(s) or something else.

What does "can't easily send SMS" mean? What problems are you having with SMS? Without details, no one could possibly give you a reason or solutions.
