My computer wont start and i dont know why!

If a SMC reset fails to bring life to the MBP, make an appointment at an Apple store genius bar for a free diagnosis.

I assume you have a functioning power adapter attached to your MBP.

- Try a reset.
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- The connect to your computer and try to restore via iTunes.
- If you can turn it off, place the iPod in Recovery mode and try to restore.
- Next let the battery fully drain. After charging for an least an hour repeat the above.

Buy an external backup drive and use TimeMachine to backup your internal drive.
Storage capacity should be 2 to 3 times the capacity of the internal HD.

Classic os9 dont start

Hi all. again
my minitower G3 have a sonnet g4/700 and when I try to use os9 in the classic,try to boot, but stops...and no warning or messages..
in the loading windows the extension for the sonnet cache its desactivated by the system...but then it dont start os9
any idea?thanks

Thanks for clarifying my "Classic v. OS9 boot" confusion. I'm all better now!
RAM is a problem with Classic function at times, but you have enough.
Another simple test to consider: Can you restart the computer from your OS9 partition by using the Startup Disk in System Preferences (OSX). If it starts into OS9 (not Classic) successfully, it says that any problems that the OS9 installation is causing for Classic's use are limited to the Classic support files that Classic places in the selected OS9 folder.
I do not think this has anything to do with the Sonnet upgrade. Its extensions are already running under OSX and simply opening Classic does not shut down OSX. Might be worth a quick note to Sonnet however.

Whenever I use the Apple TV remote to choose a new program, iTunes starts on my computer and starts playing from the playlist. How do I prevent that from happening?

Your computer is picking up the remote's signal. Go into system preferences - security - general. Click on the padlock and go into advanced. Check disable remote control infrared receiver.

RAM INSTALLED BUT COMPUTER NOT STARTED

RESPECTED SIR,
I HAVE G6-2312AX HP PAVILION NOTEBOOK /LAPTOP. WINDOWS 8 INSTALLED IN IT. 4GB RAM ALREADY THERE. NOW I WANT TO ADD 4GB MORE. I PURCHASED 4GB DDR3 1600MHZ RAM AND TRIED TO INSTALL IT. BUT COMPUTER NOT STARTING. KINDLY TELL WHAT TO DO. JAI HIND
This question was solved.
View Solution.

It sounds as if you did not put in a pair of identical memory modules or did not use guaranteed compatible memry modules. You can't use the module that was already there unless the one you are adding is identical in all respects.
Only use guaranteed modules in identical pairs if you want your memory upgrade to work right the first time.

2007 iMac freezes up, rainbow wheel appears when this happens. I know the computer is starting to get old but I can't afford a new one at this time and would love to continue using my Mac, but it's frustrating. Would a fresh install or OS upgrade resolve?

My circa 2007 iMac freezes up, and rainbow wheel appears when this happens. I know the computer is starting to get old but I can't afford a new one at this time and would love to continue using my Mac, but it's frustrating. Most of the time I ONLY have 1 thing open at a time, and keep my tabs down to a minimum. I bought this to do film editing on but with it acting like this I cannot do that. I know I need a ram upgrade (currently running 2 gb) and my OS is old, 10.5.8, but I think even with it being a bit outdated it should run better than this. Would a fresh install or OS upgrade resolve this? Or any other suggestions to keep this clunker chugging along for a little while longer?

How full is the hard drive?
Do you run any virus software or hard drive "cleaner" software like MacKeeper?
If your model is from 2007 you can install up to 6 GBs of RAM.
2 GBs is the barest of minimum RAM for OS X to run on.
Especially if doing video work. You simply do not have sufficient RAM.
Also OS X 10.5.8 Leopard support ended around 2009.
You could update to OS X 10.6 Snow Leopard, at least.
It is available on disc from the Apple store for U.S. $19.99.
I Would seriously upgrade your iMac's RAM to the max. 6 GBs before doing this.
Reliable Mac RAM can be purchase from online Mac RAM source Crucial memory or OWC ( also known as macsales).

My computer is starting to do odd things

My poor old computer is starting to act up. It's a variety of things. I'll list a few, but first my question. Are there some general things I can do to give my computer a good spring cleaning. I fill it up often and archive to external drive. I am a designer and have thousands of files from many years all over the place, but organized. It feels like I just need to clean out the cobwebs and simplify to get back in control.
First of all, stuff just seems slow. Searches are slow, searches are slow, files load slow, like big photoshop files. Sometimes I think it is just sitting there doing nothing (beachballsville as we call it in the office) and suddenly it snaps to and performs the requested task. Even if I clear up 15 gigs on the drive, it doesn't change things. So I don't think it's a pure space issue.
Finder searches will work after a restart, but by the second search, it brings back no results and just keep searching even when it should be hitting a million documents. So luckily I know when everything is organized. Especially when I try to do something like a "created on" date specific search. No dice on results.
Occasionally, browsing my disk in columns mode will freak out on me and the smallest of files will take two minutes to bring up the preview thumbnail. A restart puts things to right. But it's a pain when looking through files of images for a specific image. It's fairly rare for it to have this problem, but it consistently pops up every week or two.
Once in a while, Photoshop tools windows will one place on the screen, but when I click them, I see a ghosted box the same size as the toolbox elsewhere on the screen as though my cursor thinks its elsewhere on the screen. Again, a restart fixes it. It just seems like it had a brain ****.
Programs like Photoshop and In design can take many minute to quit unless I force quit them. They will say they're not responding, but eventually they will. So if I wait for everything to close properly, it can take 10 minutes to restart my computer for all the time it takes to close the programs. That doesn't seem right.
And when I'm doing a finder search, it starts searching before I finish typing, which would be find if it let me finish typing, but it does not. It will freeze up while searching and not allow me to finish the word until it comes back with results, so don't misspell a word and type fast, or I'll get lost in beachballsville while it's spining away looking for nothing of relevance. Can I make it wait till I'm done writing the search term and click "search". It would save so much agony.
Today my active screen corners stopped responding. Guess what fixed it.
Yeah, I probably need a new machine, but it really does work pretty well most of the time. It's just that when I come across these issue at really inopportune times, it's is no frustrating.
I'm hoping someone has advice, or has corrected some of these issues in the past. I looked around the board and didn't see something that made me say, YES! that's what's happening to me too!. But I've been wrong before. Thanks for reading my tome.

My Mac got hacked. I was working on a word document when the computer suddenly started typing meaningful sentences on its own that describes how the hacker is skillful. At the that time I was on a password protected wifi and file sharing was off.

This is the first time I get hacked this bad. I was working on a microsoft word document when the computer suddenly started typing meaningful sentences on its own that describes how skillfull the hacker is. At the that time I was on a friends wifi network that is password protected (not sure about the encyrption), the Os X Firewall was on. I was using the admin profile, however, file sharing was off. I'm very careful not to install any suspecious 3rd party software.
So far I have verified permissions and fixed some errors there, and changed passwords.
Do I have to erase/format my computer and reinstall the Os? If so is it adequte to use the internet recovery tool or will it use old and possibly infected EFI/Root files?
Would appreciate the advice of all the Mac experts out there. Thanks

Please read this whole message before doing anything.
This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing.
Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects.
Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then copy it. The headings “Step 1” and so on are not part of the commands.
Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
Launch the 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 “sh” and press return. You should then get a new line ending in a dollar sign.
Step 1
Triple-click anywhere in the line of text below on this page to select it:
kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}' | open -ef
Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting. A TextEdit window will open with the output of the command. If the command produced no output, the window will be empty. Post the contents of the TextEdit window (not the Terminal window), if any — the text, please, not a screenshot. You can then close the TextEdit window. The title of the window doesn't matter, and you don't need to post that. No typing is involved in this step.
Step 2
Repeat with this line:
{ sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix\.cron)|org\.(amav|apac|cups|isc|ntp|postf|x)/{print $3}'; echo; sudo launchctl getenv DYLD_INSERT_LIBRARIES; echo; sudo defaults read com.apple.loginwindow LoginHook; echo; sudo crontab -l; } 2> /dev/null | open -ef
This time you'll be prompted for your login password, which you do have to type. Nothing will be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step.
Step 3
{ launchctl list | sed 1d | awk '!/0x|com\.apple|org\.(x|openbsd)/{print $3}'; echo; launchctl getenv DYLD_INSERT_LIBRARIES; echo; crontab -l 2> /dev/null; } | open -ef
Step 4
ls -A /e*/{cr,la,mach}* {,/}Lib*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts .la* 2> /dev/null | open -ef
Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting.
Step 5
osascript -e 'tell application "System Events" to get name of login items' | open -ef
Remember, steps 1-5 are all copy-and-paste — no typing, except your password. Also remember to post the output.
You can then quit Terminal.

How do I get my computer to start opening up files instead of opening a pop up window rather than the file?

My computer has started opening up pop up windows that say, "Step 1: Select File, Information Gathered Successfully, Step 2: Click Show Information Button", instead of opening the file I click on. This informaion windown has generated another pop up window that suggests I visit the iTunes store for an app that will open the file. Twice I have purchased apps that the iTunes store said would open the file. Twice the apps have made no difference at all. The apps did not open the file. Even more frustrating than being sold apps that don't work is that the files I'm trying to open are textedit files created with the software on the very computer that is now refusing to open them.
How do I get beyond the pop-ups and open the files I created?
Is it possible to return the apps that iTunes said would work, but did not?

Please post a screenshot that shows what you mean. Be careful not to include any private information.
