Macbook Pro slow start up, freezing on Safari, weird things on iTunes

I have a mid-2012 Macbook Pro and it's never seemed to operate optimally. It's slow to start up and sometimes freezes on Safari pages. ITunes is difficult to navigate and does weird things. I haven't done the latest update because we don't have Wi-Fi at home. Could it be that or could I have a hardware problem? Thanks!

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you boot, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, reboot as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

MAcbook Pro Slow start up

My family owns 2 Macbook Pro's. My personal is a 13" early 2011 model (core i5) and starts OSX 10.7.3 in roughly 1 min. I am pretty satisfied with the speed
However, my family member's MBP is extreamly slow and is reletively new (2010 15" dual core i7 processor, 660 if im not mistaken). However it takes almost 5 minutes to start OSX 10.6.8. At first i thought it was just slow down, but then i realized it stays on the white screen for almost 3 min (the bios screen before the apple logo). Once the computer starts up, all other tasks are lightling fast, loading photoshop in 4 seconds.
Is there some kind of config problem or is this dramatic slow down normal?

Took me 10 minutes to reboot and be able to click anything. can you tell me why from looking at this?

Macbook pro slow start after upgrading to mountain lion

I have a macbook pro core 2 due originally runing Mac os x 10.6. I upgraded to mac os x 10.8.1 now and realized that the computer becomes slow start and shut down. Scanned with OnlyX and followed the instruction by restarting with hold down option-command-P and R, showed no help.
How could I solve the problem?
Thanks.

Remove items from System Preferences > Users & Groups > Login Items
And HD > Library > StartupItems
Then restart your Mac.

Macbook Pro wont start up (Apple logo and spinning thing all I get)

When I turn on my macbook pro I get the “tone” the Apple logo and the spinning thing but then the spinning thing just freezes up and does nothing for ever. I let it just site like that for 30 minutes then it just goes to black. It is plugged in so power is not an issue.
I tried to boot up in safe mode and again I get the tone the logo then the bar to show the safe mode then the spinning thing then nothing. I did boot it up via firewire target mode and was able to see the hard drive and all my files on my imac so the hard drive works (I think).
I do have the original install disk and am willing to start the computer fresh but have no idea how.
So any suggestions???
I also tried to turn on and run the repair mode I think that’s where I held down a key the screen went black and some commands ran then I typed somting like flvr - fv
Thanks Brad

Reinstalling Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

My macbook pro (August 2010) keeps freezing when apple mail starts up. This happens every 2nd time I turn on my Macbook Pro. This forces me to hold down the power button to restart my Macbook Pro. Does anyone else experience this, and is there a fix? Thx

since upgrading to OS lion, my mac book pro (2010 August) keeps freezing (non responsive, requires restart) when i turn on my mac and the system is trying to open apple mail. while apple mail is attempting to collect new mail, the macbook pro freezes. this happens every 2nd time i try to start up my computer. this only started happening after i upgraded to OS lion. please let me know what I need to do to fix this. being forced to restart every 2nd time i turn on my macbook pro has been very frustrating. not sure if apple mail is also the cause of my macbook pro for being very slow during start-up (on the occasion the computer doesn't freeze).

I am having similar 'freezing' problems with many programs (Mail, Safari, iTunes, etc.). I have done a clean install of Lion instead of an upgrade when it came out. Perhaps something went wrong with my install? I'm thinking about wiping and reinstalling.

My MacBook Pro 15" i7 2011 freezes suddenly minutes after starting up.

My MacBook Pro 15" i7 2011 freezes suddenly minutes after starting up the computer.
Sometimes it beeps after freezing, and keeps beeping forever until I shut down the computer by pressing the power button.
Other times the screen gets a little darker and a text appears saying I need to turn off the computer by pressing the power button and restart, but after restarting the computer freezes again. Each time I turn it on it takes only a few minutes to freeze it seams, about 2-3 minutes or less, and occasionaly it doesn´t even start up.
I don´t recall the exact version of the operating system, its MacOSX (10.6 or something)
Any sollutions?

Three beeps is usually indicative of a RAM problem. Take out one RAM chip and see what happens and then swap with the other one. See if there is a difference. Also engage the Apple hardware test and see if that offers any useful information.
Ciao.

My MacBook Pro just started to run very slow, what can I do to fix it?

My MacBook Pro just started to run very slow, what can I do to fix it?

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.
Otherwise, take the steps below when you notice the slowdown.
Step 1
Launch the Activity Monitor 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 Activity Monitor in the icon grid.
Select the CPU tab of the Activity Monitor window.
Select All Processes from the menu in the toolbar, if not already selected.
Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.
Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
Next, select the Disk Activity tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in and Writes out.)
Step 2
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.
When posting a log extract, be selective. Don't post more than is requested.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some personal information, such as your name, may appear in the log. Anonymize before posting. That should be easy to do if your extract is not too long.

My macbook pro (2011) starts up very slow and has other startup resolution

I have two problems:
My Macbook pro (Lion) starts up very slow. Many things seem to happen during startup. The screen goes small, blue, back and many times the loginscreen is coming up in a lower resolution. When I do a Pram reset it starts up with the correct resolution but after a couple of startups it goes back to 800x600 resolution (I guess). When I Log in the resolution is ok so only the login screen is a lower resolution.
Can anybody tell me what can be wrong here?
And if there is a solution beyond resetting the PRAM?

Hello,
For the screen resloution problem:
I don't know if you have solved your problem yet but i had the same exact problem this morning and was able to find the solution and fix it.
All you have to do is safe-boot your machine (hold shift key during restarting/booting) and after the next restart it should be fine.
Hope it helps.

MacBook Pro Retina late 2013 freezes on Youtube page

Hello!
So, my MacBook Pro Retina (late-2013) freezes when i open youtube home page using Safari. The cursor gets slower until everything absolutely freezes so i have to restart computer using "power" button. Yes, this problem only occurs when i use Safari, other browsers i checked are ok.
What can i do to stop it?

Hello bloomaround,
Welcome to Apple Support Communities.
From what I gather, Safari stops responding when viewing a specific webpage on your MacBook Pro. Take a look at the article linked below which provides troubleshooting suggestions that’ll resolve most issues with Safari on a Mac.
Unsupported third-party add-ons may cause Safari to unexpectedly quit or have performance issues - Apple Support
Take care,

Mid 2010 macbook pro slow to sleep. No print queu issues.

Hey everyone! My Mid 2010 macbook pro slow is slow to go to sleep. I have read several community forums and I've checked for old print jobs (which seems to be a common issue) and have found none. I've also reset all printers and jobs. Anyways, it takes 35 to 60 seconds to go sleep (until fan/harddrive turns off/I see blinking white light). This slow sleep occurs even with a complete fresh install of Mavericks, and even after installing a new SSD. I am honestly at a loss.
I did the "pmset -g log" command and I have found two reoccurring things that I think might be the reason (though I don't really understand it fully). I commonly see "TimedOut InternalPreventSleep "com.apple.powermanagement.darkwakelinger" 00:00:15" commonly and "PreventUserIdleSystemSleep "Address Book Source Sync" 00:00:30". I have bolded both of these below:

I own a late 2009 Macbook Pro, and it keeps freezing after OSX Lion installation.

I own a late 2009 Macbook Pro, and it keeps freezing after OSX Lion installation. I will post my computer's 'specs' below. I installed Lion, from Snow Leopard, through the App store. The first week, it worked like a dream, and was loving my brand new computer, or so it seemed. I then began to run into problems, and I can't confirm this 100%, but I believe it was after I updated from 10.7.1, to 10.7.2.
The freezes are sporatic at best, and cannot be narrowed down to one app. I googled the issue about two weeks ago, and found a fix involving a temporary log-in, verifying the disk, restarting the computer holding CMD+R, and repairing the disk from there. That fixed the problem. For about three or four days. From there I brought my laptop to Best Buy, where I purchased the computer (start the groans, my dad wanted the accidental damage, and he was paying, there was no argument). My warranty there was still good, but all they were offering was to check my hard-drive, and possibly ship it out. That would not be good for me, as I am a High School student, who works online.
So I then decided to go to the Apple store, see what they said. They said a bunch of people had this problem, it would cost a lot to fix, as I would need a new Logic Board. This did not make any sense to me, as I knew it was Lion's fault, so why would they not make the L-2009MBP Logic Board compatible, and why are only a few people having this problem, well a lot more than a few, but I mean not everyone.
So I asked a friend about it, and we decided to run a back up, and erase the computer, and re-install Lion. Figuring maybe my data was corrupted during install. This helped for a day or two, and happened again. So this time, we backed up only files (music, pics, documents, etc.,) and did a fresh install. I got my computer back last night. Now, I am not saying that didn't help. Previously I would have frozen about 18 times well writing this, but I have not frozen once (hopefully I didn't just jinx myself). I have gone from about one freeze every 10-15 minutes (sometimes worse), to about one every 1-3 hours. Which, let's be honest is still a lot.
So, before I just decide to go and revert to Snow Leopard on my merry way, I ask, do any of you have any other ideas? Or guarenteed fixes? I know a guarentee is a hard thing to ask for, but I am desperate, my teachers are getting angry with me for not sending work, and I know this would help a lot of people. Thank you to those who read through my whole spiel, and thank you to those who will help me!
[Ps, while I am somewhat of a noob, I know my way around a computer, so any help, or knowledge you could bestow upon me is awesome. Especially DIY fixes. (if your only advice is, don't buy a mac at Best Buy, don't bother commenting)]

My macbook pro has started running slowly! Any ideas?

My macbook pro has started running slowly. Particularly the internet (firefox and safari). I have tried repairing the disk / verifying the disk and the permissions via Disk Utility, and have also tried uninstalling and re-installing firefox, and updating the software (all up to date). None of this has helped.
The old Dell laptop we have is running faster than my mac!
I also have Parallels Desktop Installed with Windows 7, although this has never caused a problem in the past...
I am running with Mac OS X, Version 10.6.8, processor 2.66Ghz Intel Core Duo, and 4GB memory (it's normally lightning fast!).
Any ideas would be much appreciated.
Thanks.

This is a known problem with Parallels and the recent update for 10.6.8. You do not need to actually have Parallels running to experience the problem and there is nothing in Activity Monitor that would indicate the issue is related to Parallels. You can find the explanation on Parallels site. They have put out an update to correct the problem:

My early 2011 Macbook Pro on start up has wifi, but drops it soon after and never comes back, AHT shows nothing wrong. Multiple wifi's tried and same on all. I have also re-installed OSX from scratch and still happens.

I have the same problem. I have a white macbook 2010, with mavericks os. I just found my mac not powering on and then I tried to run it on safe mode by holding the shift button but it will turn off seconds after I let go of the shift button. I am able to access the desktop and use it while holding the shift button the whole time. It's a bit slower than before but I figured maybe it's because of holding down shift button.
I went to the Apple Store to have them look at my mac and I was told it's a failed hard disk. I wasn't told why he was able to conclude that a failed hard disk is causing the problem, I was just told to get a replacement. But the thing is when I ran Disk Utility it says, "disk appears to be okay." So I also feel like it's possible it's not a hard disk issue because it's also the first time it happened. My mac was working perfectly fine before all this.
Do you know anything else that could cause this problem? Were you able to find out what's wrong?
Thanks.

Try a SMC reset.

It might be helpful if you indicated the exact model/year of your MBP. Are you running Lion OSX?
Ciao.
