New MacBook Pro with 10.6.3 Freezes for 5-10 minutes every few days
I've got a brand new (i7 processor) MacBook Pro with 10.6.3 OS on it. Right from the first day I had it, it has had a problem freezing for 5 - 10 minutes every few days. When it is "frozen" nothing works - cursor doesn't track the mouse, clock doesn't increment to a new minute, nothing updates on the screen.
I turned on remote login, so I can ssh to it and see what's going on, and by running "top -o cpu" I can see that the kernel_task process is using over 100% of the CPU - other processes are getting some cycles - top, for instance - but the kernel is dominating the dispatch queue.
When this first happened, I thought the computer was dead, so I powered off and rebooted. However, once I could see that things were still running but the display was locked up, I tried waiting. Sure enough, every time the system comes back if I wait long enough. When it comes back, everything operates just fine.
Any thoughts on what I can do about this? I don't imagine that killing the kernel_task is a good idea(!). Maybe sending it an appropriate signal? I'm happy to get some more diagnostic information - just give me suggestions on what I can try. Note that it will have to be command line only, as I can only ssh into the laptop when it gets frozen like this.
Thanks.

Interesting - but that poster is complaining about the mouse and keyboard being unresponsive or going dead, not the comprehensive freeze I'm experiencing (unless "go haywire" means freezing). Not only are my mouse and keyboard unresponsive, but windows on the screen stop updating - even the clock in the upper right corner stops advancing.
For the record, I'm using the keyboard in the MBP - not much choice there - and a Razer bluetooth mouse that had no problems with my last MBP.
Still, they could be related. Something is making the kernel get very busy for a long time before it recovers. I just wish I knew what that was AND how it eventually recovers - perhaps I can accelerate the recovery if I knew the cause.
Anybody else experiencing the same thing? Note - I don't get a beachball and there is no cursor flashing (unlike the other thread on freezing). It looks like the system is completely hung, except that I can still ssh into the MBP and run things like top; overall, the CPU is over 70% idle.

I just received my new macbook pro with 16gb, 2.3 GHZ & for some reason I get a message stating that I do not have the system requirements. Help?
What are you trying to do? If you have a brand new machine, you don't need to download and install Mavericks. You already have it.

It's driving me crazy; I have a firewire, but it isn't compatible with the ports on the new macbook pro with retina display.

What kind of longevity can I expect from the SSD in a new MacBook Pro with Retina Display?
Hi all,
I recently ordered a new MacBook Pro with the Retina Display. This will be both my first computer and my first Mac that uses a SSD as the primary storage device. As the title of this post suggests, what I would like to know is what sort of lifespan/longevity can I expect to get out of it? My current MacBook Pro was manufactured in 2007 and has a stock 160GB Fujitsu hard drive that has been fantastic for me over the past 4-5 years. It continues to run like a champ, and I would hope that a brand new SSD would be able to last at least that long. Given that the new retina MBPs cannot be upgraded or (easily) user-serviced, I am somewhat curious to know whether or not Apple's new proprietary SSD modules will give out/slow to a crawl before/after my new machine becomes completely obsolete. I have been searching for articles published within the past few months on whether or not the current crop of SSDs on the market are more reliable than those introduced a year or two ago, but alas, I haven't had much luck. Perhaps it is still too early to tell?
I found a few discussion threads on here somewhere where some users indicated that their original MacBook Airs, or other SSD-equipped MacBooks, were still performing quite well and responsively after a few years of use. Can anyone substantiate this for me? How long have you been using your SSD(s) in your Mac(s), and do you think the newer models will be able to last several years? I would greatly appreciate any insight.ARealMac(PPC)User wrote:

While I think your concern is legitimate (it was mine too), I think to some extent, how long they last will be up to you. The individual cells in the flash media in an SSD have limited life spans, and SSD controllers have a variety of techniques to spread that wear around evenly (wear leveling). That wear is exacerbated by the controller having to erase a whole block of data when even just one page needs to be changed, and if not all the data in the block is still valid, more data than necessary gets moved (write amplification). To provide some extra room for all this reshuffling of data, SSD manufacturers build in extra space that's inaccessible to the user (over-provisioning), but it typically runs about 7%. (This is a good discussion of the inner workings of all this)
If you stuff your SSD full of files, so that there's very little room to do all this rearranging, I think you'll experience the slowdown you're concerned about. TRIM, which Apple's SSD's support, will help, but you can too. Allow plenty of free space on your SSD and perhaps partition it so that there is free space outside the partition (check this out to see what a difference it can make). You can't use it but the controller can as an extension of the built-in over-provisioning.
You also mention that you "will most likely use it to record several tracks and store my growing library of songs and videos." Why not instead use an external SSD connected via USB 3.0 for storage? They're relatively cheap, very fast, and keep the space on your internal working drive free. A BootCamp partition would also take up space, so you might consider using Windows in a Virtual Machine instead. VMware Fusion or Parallels would be installed on the internal SSD but the virtual machine files could go on the external.
In any case, your data is more important than your SSD, so back up, back up, back up. -

Connect my new Macbook Pro with Mountain Lion to my HP PhotoSmart B210
How can I connect my new MacBook Pro with Mountain Lion to my hp b210 printer? My printer is about 1.5 years old and works wirelessly just fine with my PC. I just switched to mac. The printer is supposed to be airprint compatible according to HP. HP has no software drivers for me to download. Instead they say to use Mac Software Update to get the software. However, there are no updates when I try that. I have tried adding the printer manually using it's IP address and can print a test page, but when I try to print using an application on the Mac it cannot find the printer or says the printer is in use. Help!!!
Are you sure it has no usb port?

I know many have this issue but i can't find a solution to the problem. i get message saying insuffisiant disk space in the volume iPhoto library and i have plenty of space available. i have the new macbook pro with retina display. i have never seen this message before and i have 2 other macbooks and have had many other also. i am assuming this is a problem with the new macbook retina. does anyone know the exact fix to this issue? i have seen many sugestions to try to fix this issue but none have solved the issue for anyone that i can find in the Apple Support Community. thank for looking into this in advance.
******A true apple fan********Actually your suggestions are the ones that i have tried. i have seen that you have tried to help others with this issue and the only one that i could find that said they found the problem said that it was an ilife update issue and it fixed it and i have no available updates. i know it has to do with something in photo stream because it happens when i create a new library and it is loading the photos but i get the message before i reach the maximum 1000 photos. so i've tried updating, new library(first backing up photos and then deleting them from iPhoto), reinstalling OSX many times, running disc utilities. I called Apple the first day i had this issue and i was the first person to call them for support with the retina display and i actually had it escalated to a senior advisor and we thought we fixed the problem but we did not. i am pretty fluent in dealing with troubleshooting these type of issues and this is the first time i'm reaching out to the community. i figured now that the retina has been out some time now that there would be an obvious answer to this issue. thanks for the quick reply.

How can I transfer my email accounts and emails from my old macbook pro with ML to my new macbook pro with ML
Do you have your system backed up to Time Machine? If so, you can open your user Library and copy your Mail folder from Time Machine to your Desktop on your new machine; then copy THAT folder to your new machine's user Library.
To get to your user Library, open Finder and Go and press the Option key. Library will show up. Click on it to get into your user Library. Now go into Time Machine and you should see your user Library for Time Machine. Restore the Mail folder to your Desktop. -
What cable can I use to transfer data from a 2008 MacBook Pro to a new MacBook Pro with thunderbolt?
You should also ask this in the MacBook Pro forum. This is the forum for the 13” white and black plastic MacBooks that were discontinued in 2010. You should also post this question there to increase your chances of getting an answer.

When trying to update getting (error surle error domain error-1100). It started yesterday, any help would be great. I have Mountain Lion 10.8.1 on a new macbook pro with retina display.
There are many people suffering from this problem right now (including me). It appears to be a server issue. Just wait and try checking for updates again tomorrow.
Some things I have heard indicate that this may be a regional problem, though what parts of the world are affected I don't know yet. A few people have been helped by deleting the following preference file (paste the path into the Go -> Go to Folder window in the Finder to locate it), though most have not:
~/Library/Preferences/com.apple.SoftwareUpdate.plist
Note that if you are trying to download iTunes 10.7, that can be found here:
http://support.apple.com/kb/DL1576
Also, note that there is no reason to be anxious to get it, as the only thing added in iTunes 10.7 is compatibility with iOS 6, which will not be available until the 19th, and the new iPhone, which will not be available until later as well. The new iTunes that was announced is iTunes 11, which is also not yet available. -
Configure New TM on a New Macbook pro with retina display Issue
I have bought a new New Macbook pro with retina display laptop (Lion moutain OS)and a new TM (2TB).
I have an internet router with wireless connect.
I plugged TM to the router with an ethernet cable.
Connect my TM to my macbook with an ethernet cable.(at this point I still cannot see TM on my Mac)
then I choose Time capsule from WiFi as shown below:
Then the airport utility (version 6.1) opened and start configuring TM but it gives an expected error when it is starting to join the TM!!!!
I have reset the TM several time but with no hope.
PS: I can configure the same TM on a normal laptop with windows 7 installed and Airport utility 5.6
I am struggling on this issue for weeks and I cannot yous TM on my macbook pro.
Help please.Time Capsule .. TC is the hardware box you bought.. Time Machine is the software you use in the Mac computer.. so what you generally refer to as TM is really TC.. !!
I can configure the same TM on a normal laptop with windows 7 installed and Airport utility 5.6
That is great.. you do not need to setup the Time Capsule at all then. It is already setup.. forget using 6.1 utility.. it is useless toy version.
Just use it.. open Time Machine and see if you can connect to the TC drive to do backup.. and to the wireless.
From your statements..
Connect my TM to my macbook with an ethernet cable.(at this point I still cannot see TM on my Mac)
You are trying to connect with both wireless and ethernet at once.. This can mess things up. choose wireless or ethernet.. not both.
If you keep running into issues.. reset the TC.. I know yet again.
Set it up using SMB names.. for both the TC itself and wireless.
Then lock the wireless channel for 2.4ghz.. use channel 1, 6, or 11 (13 in europe) and see how it goes. -
Installing Windows XP on a new MacBook Pro with Retina Display.
I just purchased a new MacBook Pro with Retina display and need to install Windows XP on it so that I may run 3 Windows programs. I have watched a few videos on the internet on how to do this through Boot Camp Assistant, and it says at one point to use the driver CD from Mac to install the drivers. I did not get any CD's with my new MacBook Pro. I also saw on some of these boards that said Boot Camp does not support Windows XP. The people at the Apple store said it can run Windows XP, so I have ordered an original version.
Question 1. Does my MacBook Pro with Retina Display running OS X version 10.8.3 able to run Windows XP?
Question 2. How do I install the drivers?Would this work? And also, what is the VM I need? Where do I get it?

Hi!
I recently bought the new MacBook Pro with the new retina display, but since it does not have a dvd/cd drive, I was going to buy an external one. I think I will be able to use it to watch dvds, but can I also play the computergame The Sims 3 on it? If not is there anything else I can do?
Thank you!Welcome to Apple Support Communities
You can try formatting the external drive on your eMac using Disk Utility and choosing a well-known format > http://pondini.org/OSX/DU1.html. It's quite possible that your new iMac would be able to read it, but first, tell us which formats Disk Utility lists.
If you have those songs in iTunes, simply go to Music folder and copy the iTunes folder to the external drive. Then, connect it to the iMac and copy the iTunes folder to Music folder.
If they are not in iTunes, copy your songs to the external drive. Then, connect it to your new iMac, open iTunes and drag the songs into it -
I have a new MacBook Pro with OS X Lion 10.7.4. The DVD player does not have a feature to store film clips. Why? This is useful for my work and I had it on my older computer? Why the loss of capacity?
I cannot recall the DVD player ever being a place to "store" videos - it is simply an app to play videos.
If your machine is new, then iMovie should be included as the "shrunk" version of iLife is included with Lion (iMovie, Garageband, and iPhoto). However, iMovie is not a place to store videos either - it is a video editor. You import your clips and edit them in order to then burn to a DVD or share via a social media site.
Have you considered simply dragging the clips to your folder "Movies"? That would be a great place to just store them (please be aware that videos are usually large files, so keep your hard drive space in mind so you keep a minimum free and available for the OS to operate properly): -
I have a new MacBook Pro with OS10.8.2 and cannot get Contacts to print a list of addresses with pictures showing. There is a check box selecting "picture" which has been checked - but no picture. This worked fine on OS10.7.5. Problem??
First, back up all data immediately, as your boot drive might be failing.
There are a few other possible causes of generalized slow performance that you can rule out easily.
Reset the System Management Controller.
If you have many image or video files on the Desktop with preview icons, move them to another folder.
If applicable, uncheck all boxes in the iCloud preference pane.
Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
Check your keychains in Keychain Access for excessively duplicated items.
If you have more than one user account, you must be logged in as an administrator to carry out this step.
Launch the Console application in the same way you launched Activity Monitor. 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. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Select the 50 or so most recent entries in the log. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.
