Many computer problems

I have been having so many problems with my macbook pro I have resorted to restoring my mac. But there is one problem, I lost my install CD. I called apple care and the guy told me that he would send me three fixes via email that I can try to help my computer. One was like an airport fix, because that has been my main problem. well anyways, i never got the email, so I called back and a different person refused to send them to me and said they were on this site. does anybody know what she is talking about and could show me where these are. my computer cannot connect to the internet at school and I desperately need help.

Why don't you just ask Apple to send a new install CD? It's important for many reasons. A replacement is around $10.

Many small problems in Mavericks

When user experience many small problem in daily work, I feel the design is failed.
Memory management has a lot of problem, I feel my macbook is abnormal slow after I upgraded to Mavericks. Sometime, I need to wait for several sec to get what I want.
I think this problem is extreme important for OS.
When I want to start a probelm, click once, no response, click twice, pop-up 2 times after 5 sec.
Then i change my way of work, clock one time, work on other task. 5 sec later, multi desktop switch the desktop to the starting program. Then, I don't know what I was doing.
Another is sound problem, sound doesn't work sometime and need some kind of procedure to get it back.
Please don't ask me do something to solve the problem everytime when it happen. It is OS task to work it properly.
Whatever how many great feature you added is meaningless if user daily experience is bad.

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve your problem.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to gather information about the state of your computer. That information goes nowhere unless you choose to share it on this page. However, you should be cautious about running any kind of program (not just a shell script) at the request of a stranger on a public message board. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them.
Here's a summary of what you need to do, if you choose to proceed: Copy a line of text from this web page into the window of another application. Wait for the script to run. It usually takes a couple of minutes. Then paste the results, which will have been copied automatically, back into a reply on this page. The sequence is: copy, paste, wait, paste again. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in your browser, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign ($) or a percent sign (%). If you get the percent sign, enter
exec bash
in the window and press return. You should then get a new line ending in a dollar sign.
Click anywhere in the Terminal window and paste (command-V). The text you pasted should vanish immediately. If it doesn't, press the return key.
If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know your password, or if you prefer not to enter it, just press return three times at the password prompt.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line "[Process completed]" to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report your results. No harm will be done.
8. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If it happens, please post the test results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

Itunes says I need itunes 11.1 version or later on my iphone before it will recognise the iphone. How do I update itunes on my iphone or is it a computer problem?

I have been trying to sync/back up my iphone and ipad but iTunes is saying I need to update my iphone to version 11.1 or later. I thought my phone was up to date and I can't seem to update iTunes on my phone anyway. Does anyone know how to update iTunes on my phone or is it a computer problem? I've been having problems with iTunes on my PC so I re-installed it but it's been a nightmare trying to get it to work.
This is the message I receive says " The iphone 'iPhone' cannot be used because it requires iTunes version 11.1 or later. Go to www.itunes.com.au to download the latest version of iTunes". I get a similar one for my iPad too.
When I go to the website I can only find the download for my PC but not the iPhone.
Any help would be much appreciated! Thank you!

No, your iPhone i s telling you that you need iTunes 11.1 or greater on your computer in order to sync with the computer.
I've been having problems with iTunes on my PC so I re-installed it but it's been a nightmare trying to get it to work.
Then you should fix this issue with iTunes before you try to sync your iPhone to it.

On how many computer can i install labview student edition?

I intend to purchase labview student edition in a near future, and i was wondering on how many computer may i install it. All for personnal use. I currently have 2 desktop, and one laptop. But I will soon get a surface 2 pro and my laptop start to be old so I will also replace it soon, and I was wondering if I could get the student version work on all those.

If you are a student, you can get a renewable 6 month license for free here. no need to purchase anything.
As for the number of computers you can install it, you need to read the Software Agreement. Look for section G(1). The software can be installed on up to three computers but can be used only on a single computer at any given time. If you get a new computer, just deactivate on the computer to be retired and activate on the new computer.

On how many computer can I install Premiere Elements (one licens)

On how many computer can I install Premiere Elements (one licens)

number
What are the computer operating systems involved? Are you installing from installation files (from online download purchase) or from installation disc
(from purchase in boxed packaging)? Answers to those questions would probably get you the best possible answer to your question.
If installation files.....
You are not going to be able to install a Premiere Elements Windows purchased serial number on a Mac computer or a Premiere Elements Mac
purchased serial number on a Windows computer.
If installation discs...
Box packaging typically comes with two installation discs....one for Windows and one for Mac. In this type of situation, typically you use one
serial number for them both. If that is the case, then the following applies...
Adobe allows you to use the same purchased activated serial number on no more than 2 of your computers. And, you do not use them at the same time.
If you are dealing with two computers with the same operating system, then you should be able to use that same purchased serial number for that operating system on no more than 2 of your computers. Again, you do not use them at the same time.
Please let us know if any questions or need clarification.
Thanks.

How do I get my Mac, G5, 10.5.8, to print? Printer tech support thinks it is a computer problem. Any ideas?

Hi Dwayne,
If necessary (unless your operating system already contains the printer software needed), a downloadable driver for a Deskjet 5420v Photo Printer (is this the exact model?) and Mac OS 10.5 appears to exist according to the support web page below:
http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?product=1105187&lc=en&cc=us& dlc=en&lang=en&cc=us
To begin with, have you verified that the printer is able to print at all (that the print cartridges are OK, et cetera)? This can usually be done by trying to print a test page (from the computer) via an HP printer utility, or possibly by generating a self-test page (without a connected computer) using an appropriate button combination on the printer itself.

What is the best way to remotely access my sister in laws Mac who lives in another city to help her with her computer problems?

as stated above
What is the best way to remotely access my sister in laws Mac who lives in another city to help her with her computer problems?

The best way? Get her to bring it to you, especially if she makes good cakes.
Apples Back to my Mac isn't really suitable for this - it is designed for a single person who wants their Apple ID on the system. It would mean she would have to share hers with you & you would also have to setup her Apple ID on your Mac - it is messy & causes trouble with iCloud, iTunes etc.
You can try Messages if she is able to begin a session with you, see the 'invite to share screen' in the menus, weirdly you need to use a service that isn't from Apple.
Messages (Mavericks): Share your screen
It may be better if you to setup LogMeIn or GoToMyPC. They should 'dial out' & maintain a constant connection so you can login whenever the Mac is powered up. It won't, require a human to initiate the process at the other end, just be aware that the router may cause issues depending on what is configured, you may need settings to enable automatic port forwarding - it really depend on which option you choose.

More of a computer problem but...

I recently had some computer problems and ran a System Restore on my computer. Once it restarted and "restored" everything, my itunes would no longer open. It says "This action is only valid for products that are currently installed." So I tried to install the latest version of itunes hoping to replace whatever had been lost that was stopping it from opening. However, Itunes gets stuck in the setup and won't save to my computer. The message says "The path... cannot be found. Verify that you have access to this location and try again, or try to find the installation package 'iTunes.msi' in a folder from which you can install the product iTunes."
My final hope was that if I uninstalled it completely and started from scratch it would work, but now I get the same message as above when it tries to uninstall as well.
If anyone has any ideas I'd really appreciate it, at this point I'm stuck with an iTunes that won't open, reinstall, or uninstall. I've also tried plugging in my Ipod, and it connects to something and says not to disconnect it, but nothing will open or run on my computer. Help please!
Windows XP

With that one, let's try the following procedure.
First, head into your Add/Remove programs and uninstall your QuickTime. If it goes, good. If it doesn't, we'll just attend to it when we attend to iTunes.
Next, download and install the Windows Installer CleanUp utility. Use it to clear any existing iTunes and/or QuickTime installation configuration information from the PC. (Launch Windows Installer CleanUp, find any iTunes and/or QuickTime entries in the list of programs in CleanUp, select those entries, and click “remove”.)

Next, use the the following document as a guide for manual removal of leftover iTunes and QuickTime program files:
Removing iTunes and QuickTime for Windows
Now try another iTunes install. Does it go through properly this time?

Among many other problems

Among many other problems, itunes doesn't play music, it get stuck, quicktime doesn't load, can't desinstall quicktime and install again, I've tried every version of itunes but every time I install it it tells me something funny about quicktime(desinstall firsta and then try again) but the thing is that won't desinstall.
Help please

hi claudia!
I've tried every version of itunes but every time I install it it tells me something funny about quicktime(desinstall firsta and then try again) but the thing is that won't desinstall.
what error message are you getting on the uninstall? include error message numbers if you're getting any.

How many times can I download LR due to computer problems

I have LR 5 and Elements 10. I think both are a 2 time download. My hard drive on my PC just crashed and had to replace it. Now my computer over heated itself and I will have to by a whole new tower. My question, will I have to go buy these programs ALL over again or is there some way around it where I won't have to re purchase both again?

You can download Lightroom an infinite number of times.
You can use your serial number to register Lightroom on two machines, as long as you are not using Lightroom simultaneously on both computers, and both computers are used for your own personal use. If a computer/hard disk crashes and can't be used, that doesn't count as one of your two installations.
So really, nothing is stopping you from using Lightroom and you don't have to purchase it again.

Computer problems after upgrading to Mavericks

SO many problems. I cleared out a ton of old stuff that I saw might be causing problems, and I've verified and repaired the disc, and uninstalled and reinstalled a couple of programs that I was seeing problems with in the console, but now I'm just flummoxed. It's behaving better than it was earlier, and isn't giving me the beach ball nearly so often, but it still seems like it's taking too long for a lot of things. I just reinstalled Avast and am currently letting a game update through Steam. I have the console and the activity monitor open to one side. Since I opened the console, it's been spitting out one or two messages every second, and all I can find through some internet searching is that it's something to do with the wireless connection. There's some other stuff periodically mixed in that doesn't sound good either, involving either sandboxd or mdworker. But for the most part it's along these lines:

I just reinstalled Avast
"Avast" is perhaps the worst of the whole wretched lot of commercial "security" products for the Mac. It's worse than the imaginary "viruses" you were worried about when you installed it. Not only does it fail to protect you, it throws false warnings, destabilizes and slows down your computer, and sometimes or always corrupts the network settings and the permissions of files in your home folder. Removing it may not repair all the damage, and neither will Disk Utility or even reinstalling OS X.
Back up all data, then remove "Avast" according to the developer's instructions. Reboot.
If you tried to remove Avast by dragging an application to the Trash, you'll have to reinstall it and follow the instructions linked above.
If you still have problems after following those instructions, post again.

Many computer problems
