Laggy MacBook Pro

I am using a MacBook Pro bought in August 2011 and for quite some time now, my book has been laggy when playing songs from iTunes, movies on QuickTime, and even halfway recording songs on GarageBand, the application will stop the recording and show an error (I can't remember what error this was but it was something to do with either not enough space or RAM).
For iTunes and QuickTime, whenever I play a song or a video, it will lag and 'hang' every other 5 seconds and then the file resumes playing. And this has been getting on my nerves because now I cannot listen to songs or watch videos with ease. (even youtube videos are sometimes laggy. the audio runs but the video hangs for a while and then it catches up and you see the video going at 1000times the normal speed before 'normality' and this happens every other 5 seconds or so.)
GarageBand is like what I have mentioned above.
Anyone has advice on this problem? Everything is up-to-date (except I'm still running on Lion).
iTunes 10.7 (21) 64-bit
MacBook Pro (10.7.5)
Processor Name:          Intel Core i7
Processor Speed:          2.2 GHz

Memory:          8 GB
I have 8GB of RAM and using 2 GPU's, Intel HD Graphics 3000 and AMD Radeon HD 6750M.
Also, I have 350GB free out of my 750GB of HDD space.
The applications were running individually so CPU usage is basically 1%. It's like starting up the computer and opening iTunes and clicking play and the lagging occurs.
Deeply appreciative of help/suggestions/tips.
Thank you!

Complicated problem: Laggy Macbook Pro, now not booting

I am facing a very complicated issue with my unibody Early 2011 15" Macbook Pro (2.2 ghz core i7, 4gb 1333mhz ram, amd radeon 6750m, if you need hardware details).
I guess the issue started after my computer started to get laggy for no reason at all: it was never the GUI that lagged, but whenever I would perform some data-dependent tasks such as playing a video, or trying to open a big file. This lagging did coincide with some of my friends playing around with magnets around my computer (which may have possibly corrupted hard disk data).
After it got laggy, another major problem hit my MacBook, where I plugged in an old, broken USB into one of the ports by accident, and the computer suddenly shut it self off. The computer then seemed to have no power at all, with no response to pressing power button, or the battery indicator button. I feared the worst: that my logic board had been fried, so I immediately took my computer to the Apple Reseller. The technicians there said it was no problem at all, just that my motherboard had shut itself of in order to protect itself from a USB power shortage, and he unplugged and replugged this one small component on the logic board, which I am guessing is the Power Management Unit, and my computer miraculeously started booting.
So then, I get back home, and the laggy problem is still there. I just had to cope with the problem for a few days, until I go back to the Apple Reseller, but then suddenly, after a restart, the computer started not even booting. The grey apple icon would blink, and turn into a circle with a cross icon. Checked online, and this is apparently related to corrupted system files. This is where I began to suspect that the USB shut-off from few days ago, did more damage than the technicians thought: maybe related to the hard disk, or RAM.
But then again, it could have just been a coincidental corrupt hard disk from my actions, so I wiped/repartitioned my hard disk, and restored the OS and my files from a TIme Machine Backup. Again, the problem was still there, so I thought it might be to do with my backed up system files, so I did a fresh install of Lion.
The fresh install of Lion seemed to eliminate all lagging problems, but after I started copying my files and installing applications from Time Machine, the lagging problem gradually returned. So another question arose, was it a faulty hard disk, or a corrupt file or application that was making it laggy? To check if it was my hard disk, I did a zero-over erase of the entire disk with Disk Utility, and sure enough, the writing process failed in the middle.
After thinking I zeroed in on the problem, I replaced the hard disk in my Macbook Pro with another 750gb Toshiba SATA drive, and did a clean install of Lion. Once again, the laggy problem was gone, but just like the old hard disk, the laggy problem returned after I started copying files over and installing applications. Switching applications would take forever, and accessing folders on my hard disk would also be laggy. Playing videos was impossible, but the GUI (dock, spaces, etc) were all very responsive.
Now, I thought the problem is either with faulty RAM, or my hard disk reader is broken (since two hard disks, although the original one was faulty, both failed). I read online that the Apple Hardware Test (AHT) can help identify and pinpoint hardware problems, so I inserted the 2nd disk that came with my computer (Applications Install), and pressed D, but then nothing came up. After countless attempts, I maybe thought it was the wrong disk, so I inserted the 1st disk (OS Installer), and held D while booting, but still, AHT would not load.
After countless attempts at loading AHT, all of which led to me forcing shut down/holding power button after seeing the Apple logo, brings the problem to where I am at now: my Macbook does not boot into the login screen. After the Apple logo, and the spinner wheel have appeared, the screen turns white and the display becomes an infinite loop of switching from a gray color, to a white color.
This problem is frustrating me very much, because there are so many possible causes, and the problem persists even after reinstalling the OS, and even replacing the ard drive. The logic board shutoff could be the cause, but then again, the lagging problem started way before it happened. Somebody please tell me what is the problem, and what I should do? Thanks in advance.

Didn't know my magnets were strong enough to corrupt hard disks.
Yes, it's a method used to destroy data on a hard drive as it's recorded using magnetic fields, either "on" or "off" to represent the 1's and 0's that make up the basic building blocks of your data.
But, the magnet does not explain why the hard disk reported an error when being erased with zero-over option.
When the driver software has a problem reading the data on the drive, it assumes it's a bad sector, then maps it off and uses a spare. You likely ran out of spares.
I just tried zero-over erasing the second, good hard disk that replaced the original, but again, it fails. Is this a common problem with the zero erase option?
No.
or is it something to do with my hard disks, or some sort of damaged hardware in my computer?
Well this is drive #2 and it's new, and you get the same problem.
It's either something your doing, (like moving the hard drive/ computer while it's operating thus the heads are striking the platters) or it's a hardware defect, or perhaps the magnets did other damage we can't see, perhaps it's magnatized the computer and that's affecting the hard drive or electronics.
May be a loose or defective cable.
It's time for a hardware evaluation at this point.

How to fix a 'laggy' Macbook Pro?

Recently, my Macbook Pro began to lag a bit. When i toggled from safari to Microsoft Word, the rainbow wheel would pop up. Also, occasionally when i type text it takes a few seconds before the words coordinate with the keys. Does anyone know what the problem is or how to fix it?

Hi there! I am a very novice guy but let me try to help you with what knowledge I have!
1- Leave your Mac open and stop it from going to sleep for a whole night! Sometimes Mac likes to do some house-cleaning and maintenance inside and leaving ti up all night will make sure you've given it enough time to do that!
2- If you have bootcamp-d windows in your Macbook then go to the system preferences and choose spotlight and then under privacy tab, put the BOOTCAMP drive in it so that your Mac stops indexing windows files and settings for the spotlight!
3- Download the cleanmyMac or snowleopard cache cleaner and do a house-cleaning! Mac has the tendency to use a lott of space as cache and virtual storage and those two softwares will make sure you get rid of the unwanted junkies!
4- Before closing the Safari click on the Safari in the menu bar and click on reset safari! A lot of choices will come and you can empty everything over there including history, unless you want safari to remember the webpages you visited!
5- Some of the Apps over time gets corrupted so you can re-check the premission setting and uninstall the unused, corrupted apps.
hope it helps..:) thank you

MacBook Pro is lagging, how to fix?

Any experience on diagnosing a laggy Macbook Pro? It's not even 3 yrs. old, its a 15", w/ all photos & videos on an external hard drive.
2 gigbites free in memory. 8 gb Ram. Suggestions? (External HD usually unplugged, unless using iphoto.)
Thanks, Love my Mac!
Dallas, TX

2 GB free hard drive space? That would definitely do it.

Why is the 2010 i7 MacBook Pro so laggy on Lion?

Now, here's my issue: my 2009 iMac works with lion perfectly with all applications. My MacBook Air, which I'll admit, I don't use much, appears to work fine under Lion; however, my 2010 i7 MacBook Pro is just pathetic at times. Now, it's most apparent in Safari, maybe that's just because I use Safari most often, where scrolling and zooming is very laggy. Sometimes I'll expand my fingers and have to wait a good 2 seconds or more to see the zoom animation cut through where it's supposed to be, relative to how far apart my fingers are. This does not happen on my 2009 iMac with the Magic mouse hooked up, but it is quad-core i7 vs the MacBook Pro's dual-core i7. It just doesn't make sense though. I know the Sandybridge i5's in the lowend MacBook Pros are more powerful than my i7 MacBook Pro, but they can't be so much more powerful that they lack all of these animation defects, while I feel them full force, right? Maybe it's the GPU? I honestly haven't tried keeping my Pro set to it's GT 330m because I thought it to be more of a CPU issue because the animation sems so simple even for the Intel Graphics 2000. I also see a huge issue when entering text in a text field, though this also happens in pages. I'll type words and they wont appear until seconds after. I'm rather perplexed at this issue, is the problem Lion? Should I report this under Apple Care, or what? Thanx for the help, guys!

Back up your Mac if you have not done so already. To learn how to use Time Machine read Mac Basics: Time Machine backs up your Mac - Apple Support.
Kaspersky cannot possibly convey any benefit and its presence will only complicate troubleshooting. Uninstall it according to its instructions. This document may help, though it appears woefully outdated: http://support.kaspersky.com/8366. Unfortunately I can't help any more than that. I attempted to install Kaspersky to evaluate it, but the installer repeatedly failed for reasons I was unable to determine.
Determine if the problems also exist in Safe Mode:
Safe Mode or "Safe Boot" is a troubleshooting mode that bypasses all third party system extensions and loads only required system components. Read about it: Starting up in Safe Mode
You must disable FileVault before you can start your Mac in Safe Mode.
Starting your Mac in Safe Mode will take longer than usual, graphics will not render smoothly, audio is disabled on some Macs, and some programs (iTunes for example) may not work at all.
Merely starting your Mac in Safe Mode is not intended to resolve the problem, it's to observe its performance without certain additional components.
To end Safe Mode restart your Mac normally. Shutdown will take longer as well.
System performance problems for reasons that cannot be isolated to any other cause justify an SMC reset. Be sure to read the procedure carefully and follow all the steps exactly as written, even if they seem inapplicable or trivial.
Corsair RAM is known to be deficient on Macs, and Google products are notorious for causing Macs to perform poorly.

My MacBook Pro has been incredibly slow and laggy

So my MacBook Pro has been pretty much inoperable for a couple of months. The computer crashed and afterwards it would constantly lag. I did a fresh install thinking it would solve the problem, but it did not do anything. I took the computer to the Genius Bar, and they claimed that it was because I was running too many apps and that the computer was slowing down (doesnt make too much sense considering its a mid 2012 and on a fresh install) and then promptly sent me home. When you flash the memory in the beginning, sometimes it will be less laggy for a second, but then start lagging a couple minutes after computer use (this is still on a virtually clean install). I took their suggestion and added a SDD thinking it might help. Nope. So the hardware tests/diagnostics are all normal and I have no idea whats going on. It literally took me 10-15 minutes to run the EtreCheck and copy into mail so I could post these results from another computer. I will love anyone forever if they could explain to me how to fix this.

Things You Can Do To Resolve Slow Downs
If your computer seems to be running slower here are some things you can do:
Start with visits to:     OS X Maintenance - MacAttorney;
                                  The X Lab: The X-FAQs;
                                  The Safe Mac » Mac Performance Guide;
                                  The Safe Mac » The myth of the dirty Mac;
                                  Mac maintenance Quick Assist.
Boot into Safe Mode then repair your hard drive and permissions:
Repair the Hard Drive and Permissions Pre-Lion
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. 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 installer.
Repair the Hard Drive - Lion/Mountain Lion/Mavericks
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the Utilites 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 disk icon and click on the arrow button below.
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, then click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
Restart your computer normally and see if this has helped any. Next do some maintenance:
For situations Disk Utility cannot handle the best third-party utility is Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible.
Note: Alsoft ships DW on a bootable DVD that will startup Macs running Snow Leopard or earlier. It cannot start Macs that came with Lion or later pre-installed, however, DW will work on those models.
Suggestions for OS X Maintenance
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger. These utilities have limited or no functionality with Snow Leopard or later and should not be installed.
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive.
Helpful Links Regarding Malware Protection
An excellent link to read is Tom Reed's Mac Malware Guide.
Also, visit The XLab FAQs and read Detecting and avoiding malware and spyware.
See these Apple articles:
Mac OS X Snow Leopard and malware detection
OS X Lion- Protect your Mac from malware
OS X Mountain Lion- Protect your Mac from malware
About file quarantine in OS X
If you require anti-virus protection I recommend using VirusBarrier Express 1.1.6 or Dr.Web Light both from the App Store. They're both free, and since they're from the App Store, they won't destabilize the system. (Thank you to Thomas Reed for these recommendations.)
Troubleshooting Applications
I recommend downloading a utility such as TinkerTool System, OnyX, Mavericks Cache Cleaner, or Cocktail that you can use for removing old log files and archives, clearing caches, etc. Corrupted cache, log, or temporary files can cause application or OS X crashes as well as kernel panics.
If you have Snow Leopard or Leopard, then for similar repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. Applejack does not work with Lion and later.
Basic Backup
For some people Time Machine will be more than adequate. Time Machine is part of OS X. There are two components:
1. A Time Machine preferences panel as part of System Preferences;
2. A Time Machine application located in the Applications folder. It is
    used to manage backups and to restore backups. Time Machine
    requires a backup drive that is at least twice the capacity of the
    drive being backed up.
Alternatively, get an external drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
1. Carbon Copy Cloner
2. Get Backup
3. Deja Vu
4. SuperDuper!
5. Synk Pro
6. Tri-Backup
Visit The XLab FAQs and read the FAQ on backup and restore. Also read How to Back Up and Restore Your Files. For help with using Time Machine visit Pondini's Time Machine FAQ for help with all things Time Machine.
Referenced software can be found at MacUpdate.
Additional Hints
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
Add more RAM. If your computer has less than 2 GBs of RAM and you are using OS X Leopard or later, then you can do with more RAM. Snow Leopard and Lion work much better with 4 GBs of RAM than their system minimums. The more concurrent applications you tend to use the more RAM you should have.
Always maintain at least 15 GBs or 10% of your hard drive's capacity as free space, whichever is greater. OS X is frequently accessing your hard drive, so providing adequate free space will keep things from slowing down.
Check for applications that may be hogging the CPU:
Pre-Mavericks
Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Mavericks and later
Open Activity Monitor in the Utilities folder. Select All Processes from the View menu. Click on the CPU tab in the toolbar. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Often this problem occurs because of a corrupted cache or preferences file or an attempt to write to a corrupted log file.

Jerky, laggy graphics on windows 7 on macbook pro but graphics are fine on OS X

I installed windows 7 and all the apple support files for windows using bootcamp on my brand new macbook pro 15inch.
I get very noticeable laggy, jerky graphics on videos that i play with VLC or windows media player in Windows 7.
If there is motion in the video you can really see it is not smooth.
and the quality of the display of youtube videos is much better on OS X than on windows but not jerky.
BUT if i play exactly the same files on OS X mountain lion they play perfectly,please help.
The apple support files for windows are up to date as well - I checked.
My Spec is Windows 7,
And the most recent OS X Mountain Lion.
2.6Ghz quad core Intel i7
16 GB RAM.
and the rest of the normal spec for a brand new macbook pro.
Any help would be massively appreciated.

Uninstall the graphic drivers you have, then download and install these.

Can somebody diagnose why my new MacBook Pro is so slow and laggy?

I just bought this MacBook Pro (OS X 10.8.2) a month ago and it had been performing very well until last night. I tried to stream a hockey game through Chrome and the browser crashed. I didn't think it was a serious issue at first; I tried to force quit Chrome but everything just slowed down even more. Eventually I just shut it down by holding the power button, hoping that it would be fine once I started it back up.
But it wasn't fine. It took forever to boot up, and once it did, everything was slow and laggy. There is delay using the trackpad and keyboard, applications are taking ages to open and sometimes won't respond, the color wheel is popping up for minutes at a time, etc. It even seems like the internet itself is slowed down; I've tried different browsers in different locations of varying internet connections and they've all been very slow to load pages. It's like the whole machine suddenly caught the flu or something.
I tried disk utility, but it says there's no problems. The activity monitor doesn't show any significant CPU usage, and even after I cleaned the caches for Safari and Chrome, all the problems still persist. I thought it might have caught a virus or some kind of malware, but I've been told that's highly unlikely. Could it have something to do with Chrome or Flash (I was trying to update the latest Flash plug-in or something before the browser crashed)? Like I said, the machine's fairly new, so not much of the RAM is used up. Could anyone help me figure out what's wrong?

My macbook pro 2010 is really laggy and slow any help

my macbook pro 2010 is really laggy and slow any help

Hi..
Not enough free space on the startup disk can slow the system down.
Right or control click the MacintoshHD icon on your Desktop.
Click Get Info. In the Get Info window you will see Capacity and Available. Make sure there's a minimum of 15% free disk space.
Freeing Up Hard Disk Space - Mac GuidesFreeing Up Hard Disk Space - Mac Guides
Starting up in Safe Mode deletes system caches that can help also. Keep in mind a Safe Mode boot takes longer then a normal boot so be patient. Once you see the Desktop, click the Apple menu icon top left in your screen. From the drop down menu click Restart.
And disabling the resume feature can help.
Open System Preferences > General. Deselect: Reopen windows when quitting and re-opening apps

Macbook Pro is slow/laggy and makes a weird noise

Hello members,
I have a Mid-2010 Macbook Pro running Mountain Lion with all the latest updates. Everything was fine until 3 days back, when it started acting up. Moving the cursor was extremely laggy, and starting up any application takes forever. I also noticed a weird noise, more like a phone pulse dial, coming from the front. It repeats itself every 3 seconds, so I first thought it must be the HDD failing. But I have run all sorts of hardware tests but every test seems to infer that the HDD is working fine. Is it possible that the HDD is failing even though it doesn't show up on any test? The Apple store nearest to me is more than a 3 hour drive away, so it's almost impossible to go there in person. Can anyone please help? Thanks in advance.

Online video playback is severally laggy/choppy on my macbook pro 2011?

hey guys, got a bit of an issue here. I've been noticing some SEVERE lagging issues whilst viewing online (streaming) video, from various sites, including, novamov, youtube, and others. the videos rarely stop to buffer as i have a fast connection, but yet they still seem to lag wildly. what i mean by this, is the sound will continue as normal, the the picture will freeze sometimes for a good 5 seconds or so before resuming, this is happening increasingly more and more..
i am running Mac OSX Lion (latest Update) on my:
MacBook Pro
17-inch, Early 2011
Processor 2.3 GHz Intel Core i7
Memory 8 GB 1333 MHz DDR3
Graphics Intel HD Graphics 3000 512 MB
Software Mac OS X Lion 10.7.3 (11D50b)
If it helps my hard drive space is:
Macintosh HD
Capacity: 664 GB
Available: 179.79 GB
The browser i am using is the latest version of Safari, although i have tried firefox and chrome and i experience the same issue.
I have Sophos anti-virus installed and run regular scans on my system (all clear)
i really can't think of anything else which could be causing an issue here. I haven't installed any additional software for a while, not in the time frame since the error started to occur.
I am quite surprised to be experiencing such issues as lagging on something as simple as a youtube video when my £3000+ computer handles heavy applications such as Final cut pro and Photoshop with ease...
i MUST be missing something here,
I really would appreciate any help i can get here.
thankyou very much for your time

Hey Carolyn,
Worked a treat, de-jaggy video for first time in months!!! Only point of clarification, I manually deleted the Flash plug-in before I uninstalled Flash. Don't know if this was why it worked for me rather than others but hey ...
Thanks again!

Re: Online video playback is severally laggy/choppy on my macbook pro 2011?

Hi Ben...
I am quite surprised to be experiencing such issues as lagging on something as simple as a youtube video
Try troubleshooting the Flash plugin required for most YouTube video.
Quit all open browsers. I'm using Safari as a test.
Open System Preferences > Flash Player then select the Storage tab. Click: Delete All
Now uninstall the Flash plugin then reinstall new > Troubleshoot Flash Player | Mac OS
Make sure and uninstall the current plugin first.
Then launch Safari. From your Safari menu bar click Safari > Empty Cache
Now try a video.
BTW... if you have the ClickToFlash extension installed, that can prevent Flash based video from streaming. It can also be installed as a plugin in /Library/Internet-Plug-Ins.
And check to see if Safari is running in 32 bit mode. Right or control click the Safari icon in your Applications folder then click Get Info. If the box next to: Open in 32 bit mode is selected, deselect, quit then relaunch Safari.

Macbook pro choppy / laggy scrolling after wakeup

As long as the MacBook is running after Boot UI is behaving smooth,
but after MacBook went to sleep and wakes up again UI is very choppy or laggy when scrolling WebPages (all Browsers) or moving Windows.
Only way to get smooth scrolling back is to restart the MacBook
I've got a MacBook Pro Mid 2009 (MacBookPro5,3) and using Mountain Lion actually.
With Snow Leopard i haven't had these Problems

Such problems appear when upgrading a somewhat old machine to a modern OS. New operating systems demand powerful hardware to run them.
Try go to 'System Preferences' app, then to 'Sharing'; disable the option 'Screen Sharing'. Make sure its status turns to off. Restart your machine.
Disabling some of the OS features that you might not use saves processing power, this solves such problems.
Sincerely.

2010 Macbook Pro Laggy

So I have a 2010 Macbook Pro that I have been having a very difficult time with. I bought it online a coupe days ago and it has yet to work properly for me. When I boot the computer up it runs unbeleivbly laggy and the mouse jumps all over the place as well as everything going in slow motion. The fan comes on immedietaly when I power the computer on and never turns off.
I have another macbook pro that works fine So I tried swapping the Hard Drives and still the same issue. I have also tried removing the ram and reinstalling it and still no luck there.
The computer has Snow leopard installed currently and I'm running out of ideas on what it could be; maybe a motherboard issue, I'm not sure?

In addition to the SMC reset suggested by BobRz, perform A PRAM reset:

Photoshop cc laggy in late 2013 retina Macbook Pro

Hello Community
i bought late 2013 retina macbook pro,
and installed photoshop cc,
it is abnormally laggy.
by that i mean, even a small psd file, empty canvas, small brush, when i draw a line, it is laggy.
I suppose it is a driver problem
anybody has same problem?
and is there any solution?

Hi guys,
Ive posted a fairly similar topic today. On my new Macbook pro retina 13" with 2.6Ghz, 8GB RAM and 256SSD CS6 was abnormally slow and laggy when editing files that my 8 year old laptop handled perfectly.
I noticed that when I removed my wacom tablet and edited with the trackpad or a mouse the lag went away! The mpb was snappy and responsive when editing the file. \
My guess is that the wacom drivers arent updated for retina macs and they cause some sort of malfunction with photoshop.
Ill keep you guys updated if i find something better.
