Mac book pro (2008)will not start up,command-v gives (error) Import:Importer start failed for 89(kr:268435459)invalid destination port)

will not start up.
tried Command-v
message reads
(error) Import:Importer start failed for 89 (kr:268435459)invalid destination port)

First, uninstall "SuperTV" (whatever that is) according to the developer's instructions. It isn't working and it's filling the log with noise.
If you have more than one user account, these instructions must be carried out as an administrator.
Launch the Console application.
Step 1
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.
Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time when you had the problem. Post the messages logged before the boot, while the system was unresponsive or was failing to shut down. Please include the BOOT_TIME message at the end of the log extract.
Post the log text, please, not a screenshot. If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message. When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
PLEASE DO NOT INDISCRIMINATELY DUMP THOUSANDS OF LINES FROM THE LOG INTO A MESSAGE. If you do that, I will not respond.
Important: Some private information, such as your name, may appear in the log. Edit it out by search-and-replace in a text editor before posting.
Step 2
Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post shutdownStall, spin, or hang logs — they're very long and not helpful.

It was telling you that you needed Mac OS 10.6.8 or later, not itunes 10.6.8
Syncing with iTunes on a Mac or PC requires:
Mac: OS X v10.6.8 or later"

Mac book pro late 2011 not starting up

Hi there,
I have a late 2011 Mac Book Pro 15 ". It will no longer start up, looks dead, machine is fully charged and I simply put it to sleep. Now I noticed that the magsafe charger is no longer displaying a light.
Any ideas here, its out of warranty, not looking forward to a huge repair bill.
Thanks,
AJ

Some power adapters can at times be wiley and show no light but stll be functioning, though that is rare.
I assume that you pressed the power button on side of the MBP where the battery charge level is displayed.
If the battery has a charge, it should start up unless there is another issue preventing it. Likewise a MBP should work with the power adapter attached regardless of the battery status.
Try the SMC reset again. If no success, make an appointment at an Apple store genius bar for a FREE evaluation. If it is a simple fix, it may be done gratis. At any rate, you will know the exact situation and then make an informed decision.
Ciao.

Mac Book Pro/iTunes will not recognise content of freshly burned cd

Hi
So...my drive will recognise bought dvds and burned dvds. It will also recognise the content of shop bought cd. I can also burn cds and dvds. HOWEVER, it will not recognise cds burnt for me from other peoples (apple) machines. It simply says that the cd is blank. This is the same whether the cd is an mp3 cd, an audio cd or a datadisc. I have also tried to open the cd's in Quicktime and VLC but it still will not recognise.
Can anyone help m with this one? Do I just need to get a lens cleaner and if so are lens cleaners that you insert into the machine safe to use ?

So...
It would appear that now:
I cant burn dvds using toast or dvd studio pro.I can however play burnt dvds.
I cant play burnt cd's using itunes or quicktime but I can burn cds using iTunes.
Im so puzzled that any help would be brilliant.thank you.

Mac OS 10.5 /
I deleted the " Private" folder ... and emptied the trash. So the folder and its contents no longer exists on my computer at all !!!
I do have the OS 10.5 dvd that i purchased years ago...
But my computer will not start from it on its own.
My question is what is the open source or terminal language code used to tell my mac to look in the DVD rom drive for startup info? I know that im not the only person in this world who has deleted the "PRIVATE" folder and emptied the trash so it no longer exists on their machine...
That said theres gotta be a common fix for a Power PC G4 that has the OS X dvd in the rom drive but wont look to it to reinstall the vital contents of the PRIVATE folder.
Once again there is not a copy of this file or its contents in the recycle bin...
Also rebooting the machine , pressing and holding the letter C does not prompt the machine to look to the dvd rom drive.
I was reinstalling pro tools and figured I would make some room by cleaning my computers HD...
Lol It was a bad choice to delete this file ...
Thanks guys

Okay sorry it took forever to respond... But for a while there I gave up on this computer!!!!
Money's been tight lately , so taking it in to a professional was not yet an option... though I did consider it eventhough.
Anyway long story short im glad I didnt spend any money because I already had all the tools necessary to fix this issue but was going about it in the wrong way. Okay so here is my scenario and the breakdown... Though this may not fix the issue for everyone :( which *****... But I know we all will have different circumstances.
Anyway here we go...
Okay so first things first.... Years ago I purchased the OS 10.5.1 disk ... So that has always been in my possession!!!!
I realize that some may not have a disk to reflash your OS to your hard drive... but if you do your in luck.
2ndly ... I had an external harddrive with all of my itunes downloaded music so it was more than okay with me to delete my primary HD because all the important stuff could either be copied over or repathed to be located.
-------If you dont want to read through the whole story the fix is summed up in the bottom section-------
Okay so now the SOLUTION!!!!
By trial and error , and pure boredom I opened up my computer to clean the inside...
AND
"Disconnected the primary HD"
and just because ....... REBOOTED my computer. Just to see what it would do.
Upon restart and though it looked like it would repeat its usual cycle...
About 1 minute in to that process my computer froze for about 2 seconds and flashed to the OS installation screen.
Mind you I havent seen this screen yet... Probably hasnt been since I installed the OS years ago.
After a bit of trial and error...
I decided to tell my computer to startup from the OS 10.5 disk located in my dvd rom drive and restarted once again...
this setting is under
Utilities / startup disk
After a little more trial and error ... I realized that I could reconnect the primary HD , restart the machine and return to the OS installation menu.
So upon this discovery
I went to the Disk Utility located under Utilities
Highlighted my primary HD located in the left hand column
Once highlighted ...
In the heading section on the right I selected the option
Erase
in which I erased My current OS on my primary HD ...
I used the first option in the list under security... Because it seemed like the least invasive and would take the least amount of time to see if this process would actually work.
I FORGOT to add something...
Another reason why I deleted my primary HD!!!!!
I forgot to say that it WOULD NOT!!!!! Show up in the STARTUP list as an option...Even After multiple reboots....
But like clockwork... Once I deleted its name IT SHOWED UP as an option!!!!
So back to the next step...
I returned to the STARTUP option under utilities ... And was then able to see MY primary HD now as a startup option...
But ofcourse it had no name because it we previously erased it.
So when Clicking my newly erased HD ... I was almost immediately prompted to REINSTALL the OS ...
Which said it would take about 57 minutes ... But I believe was alot less...
My issue was resolved ... My computer then stated the install was SUCCESSFUL!!!!!!! :))))))))))) lol ;)
It was like I was setting up for the first time ;) asking for my registration info...
The dilemma of deleting the private folder and emptying the trash is finally over resolved. Done ... and no extra money spent!!!!!!!!!
Its really crazy that the information for such a simple thing is not readily available. Especially being such a simple fix.
I know im not the only person who's had this issue , because i've seen numerous posts with similar wording.
I also know I wont be the last person to have this issue... So I hope this synopsis makes sense.
-------One more time the fix------
*Insert your OS dvd into your dvd rom drive.
*Unplug your primary HD or corrupted startup disk
*Reboot your machine...
Upon restart your primary HD will not be recognized...
* you will then be prompted to select your language.
Once selected
*Click Utilities/startup... Highlight the the selection that refers to the OS dvd located in the dvd rom drive.
* Click restart...
!!!!!!!!!!Be sure to reconnect your Primary HD Before your computer restarts and you hear the chime!!!!!!!!
If you do not replug your HD before the chime it will not be recognized.
In that case restart again.
Upon restart once again
*Choose your language...
*Click Utilities / disk utility
In the left column select and
*Highlight your HD ...
Then towards the top portion / center of the page
*Click the heading Erase
Then on the page toward the bottom
*Click security options
This will then provide erase options.
I USED THE FIRST OPTION
"Dont erase data"...
*click OK
* click erase...
Once erased which should take a few seconds
*Cancel the disk utility...
* Click Utilities / startup
And your newly erased HD should now appear in the list.
* Select your drive from the list by highlighting
It should no longer have a name.
*Once selected, you will then be prompted to restart and install the OS to your newly erased HD...
Thats it!!!!
Once everything reinstalls re-add your personal info or registration info and you are up and running.
Goodluck ;)

My Mac Book Pro suddenly will no longer connect to the Internet at my house. Help?

My Mac Book Pro suddenly will no longer connect to the Internet at my house. My son's MacBook connects just fine. My MacPro connects at work, at Starbucks, etc. just fine, but not at my house. My son's however has no problem whatsoever. I assume that since his computer connects that the router and modem is not the problem. And since my computer connects everywhere but here . . . . it is not a hardware issue. When directly connecting my MacBook Pro to the modem or router the problem was the same. . . no connection. Help?

From the menu bar, select
 ▹ About This Mac
Below the "OS X" legend in the window that opens, the OS version appears. Click the version line twice to display the serial number. If the number is missing or invalid according to this web form, take the machine to an Apple Store or other authorized service center to have the problem corrected.

What OSX should I use on my 2009 MAC Book Pro? Will Yosemite run

Hi I have a Mac Book Pro from 2009 and I was wondering what OSX should I use on my 2009 MAC Book Pro? Will Yosemite run properly on this computer?

Welcome to Apple Support Communities
Your Mac supports OS X Yosemite. If you need to upgrade your Mac, do it, but if you are happy with the OS X version you are running or you do not like changes (OS X Yosemite has got an interface change), you can keep it always that it is not very old.
In order to upgrade to OS X Yosemite, it is as simple as opening the Mac App Store and downloading OS X Yosemite. When the download finishes, the installer will show up, so follow its steps. Before upgrading, it is important to make a backup of your files with Time Machine -> Mac Basics: Time Machine backs up your Mac - Apple Support You can also check that your applications are compatible with Yosemite in this website -> http://www.roaringapps.com
OS X Yosemite should run properly, but I recommend you to run it with at least 4 GB of RAM (you can check how much RAM you have in the Apple menu -> About this Mac). In case Yosemite runs slowly, the backup you made will let you go back to your old version.
