Macbook Pro lags after Yosemite upgrade

Hi,
I upgraded my Macbook Pro (8gb, Jan 13) to Yosemite yesterday....
Since the upgrade it is painfully slow and sluggish. It takes ages to boot up. Once finally booted up everything lags. I see the coloured pinwheel permanently.
I tried running the internet but it's impossible to move around and type. It freezes constantly. text has to catch up with my typing.
I have tried all the tweaks and scans I can find and even reinstalled it. Nothing has changed. I am hardwired to the web so wireless is not an issue, but I did turn off bluetooth etc as advised.
I am at the point where I will need to go to recovery and revert back to its original purchased state!!
Any advice would be greatly appreciated. I am desperate to get back to a machine that works!

Hi ..
Since boot time is slow open System Preferences > Users & Groups > Login Items
Remove all items listed there. Same for HD > Library > StartupItems
Restart your Mac to monitor boot time.
And make sure there's enough avaiable disk space. Click the Apple  top left in your screen. From the drop down menu click About This Mac > More Info > Storage. Make sure there's at least 15% free disk space.
Check the hard drive.
Launch Disk Utility located in HD > Applications > Utillities
Select the startup disk on the left then select the First Aid tab.
Click: Verify Disk (not Verify Disk Permissions)
If Disk Utility reports errors, restart your Mac while holding down the Command + R keys.
From there you should be able to access the built in utilities in OS X Recovery to repair the startup disk and restore OS X.
As far as the internet is concerned, if you are using Safari, try the following:
From your Safari menu bar click Safari > Preferences then select the Privacy tab.
Click: Remove All Website Data
Then delete the cache.
Open a Finder window. From the Finder menu bar click Go > Go to Folder
Type or copy paste the following
~/Library/Caches/com.apple.Safari/Cache.db
Click Go then move the Cache.db file to the Trash.
Quit and relaunch Safari to test.
If that doesn't help, troubleshoot Safari extensions.
From the Safari menu bar click Safari > Preferences then select the Extensions tab. Turn that OFF, quit and relaunch Safari to test.
If that helped, turn one extension on then quit and relaunch Safari to test until you find the incompatible extension then click uninstall.

MacBook Pro lag after Yosemite 10.10.3 now won't boot

About two days ago I updated my MBP 13" (mid-2012) to the latest Yosemite OS update (10.10.3) after which left my laptop constantly lagging and crashing a lot of applications i was using. Last night it was really lagging so I attempted to restart my MacBook but it wouldn't work so I held down the power button to turn it of but when I tried to turn it on and log in again a bar below my user picture would appear, as if it were loading something, then the laptop would turn off again.
I have attempted to use Apple Hardware Test, because I assumed it may have some thing to do with the RAM, but even during the test it was very clear that it was lagging whenever I tried to move the cursor. The test also appeared to have frozen because it just stayed at the same place for about an hour so I just closed my laptop and left it as it was since it was very late at night.
When I turned on my laptop on again this morning the loading bar and subsequent shut down is still happening. Any idea what I can do? I did back up my files two weeks ago so I wouldn't mind if I lose everything in order to fix this.

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
To restart an unresponsive computer, press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If a desktop Mac hangs at a plain gray screen with a movable cursor, the keyboard may not be recognized. Press and hold the button on the side of an Apple wireless keyboard to make it discoverable. If need be, replace or recharge the batteries. If you're using a USB keyboard connected to a hub, connect it to a built-in port.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

Why won't my 2011 MacBook Pro restart after Yosemite installation?

Why won't my 2011 MacBook Pro restart after Yosemite installation?

What symptoms are you seeing?
At what point does it get stuck?
Is it failing to Restart, or failing once it restart?
what exactly is on the screen, if anything?
Do you get the chime? the gray Apple? The spinner? black screen? gray screen? prohibitory sign?

The report show many hard drive errors. Did you run Disk Utiltiy from your recovery partition before upgrading the OS? Always a good action. You can run Disk Utility now while booted from your Recovery partition (press and hold command-r while booting) and see it it can repair the issues.
You hard drive is not full enough yet to cause major slowdowns but you need to keep and eye on it and make sure it does not get any more full. You have 53GB (about 10 percent) free space now. You should make sure you don't go below about 20GB. If your physical RAM fills up, Virtual Memory must find qualifying blocks on the hard drive to write swap data and, when teh drive gets crowded, VM's search process slows as does yo uoverapll performance.
You have LOT of third-party stuff installed. "NoSleep" sounds like it could be modifying system resources; see if disabling it helps.

I would get rid of uTorrent because you can download all sorts of malware using it. Also try taking Chrome out of your login items as it tends to be a resource hog.

Acrobat Pro crashing after Yosemite upgrade

Since upgrading to Yosemite, every time I read PDF documents with Acrobat Pro (11.0.09) it crashes. This is usually when scrolling. I am using a MacBook Pro 15in retina (2013). I would be grateful for any help?

Hi ..
Since boot time is slow open System Preferences > Users & Groups > Login Items
Remove all items listed there. Same for HD > Library > StartupItems
Restart your Mac to monitor boot time.
And make sure there's enough avaiable disk space. Click the Apple  top left in your screen. From the drop down menu click About This Mac > More Info > Storage. Make sure there's at least 15% free disk space.
Check the hard drive.
Launch Disk Utility located in HD > Applications > Utillities
Select the startup disk on the left then select the First Aid tab.
Click: Verify Disk (not Verify Disk Permissions)
If Disk Utility reports errors, restart your Mac while holding down the Command + R keys.
From there you should be able to access the built in utilities in OS X Recovery to repair the startup disk and restore OS X.
As far as the internet is concerned, if you are using Safari, try the following:
From your Safari menu bar click Safari > Preferences then select the Privacy tab.
Click: Remove All Website Data
Then delete the cache.
Open a Finder window. From the Finder menu bar click Go > Go to Folder
Type or copy paste the following
~/Library/Caches/com.apple.Safari/Cache.db
Click Go then move the Cache.db file to the Trash.
Quit and relaunch Safari to test.
If that doesn't help, troubleshoot Safari extensions.
From the Safari menu bar click Safari > Preferences then select the Extensions tab. Turn that OFF, quit and relaunch Safari to test.
If that helped, turn one extension on then quit and relaunch Safari to test until you find the incompatible extension then click uninstall.

MacBook Pro crashes after Leopard upgrade

Since upgrading to Leopard my MacBook Pro now runs at least 3 times slow than with Tiger.
Also Safari crashes like mad, almost every web site I visit it crashes (6 attempts to write this).
Plus if you try and search online ebay, istockphoto, click in the search bar then the pin wheel appears and Safari crashes!
I've also noticed how much more frequent the Mac now crashes almost like it's in a crashing competition with an under-powered Vista machine.
I think I will try a clean install to see if that makes a difference, if not it'll be back to Tiger and the land of not crashing every 10 mins.

As there is no "clean install" option, I can only guess you mean an erase and install:
http://discussions.apple.com/thread.jspa?messageID=607614
The crashing may be do to installed third party applications which aren't compatible with 10.5, permissions which are in need of repair, or insufficient disc space, or third party widgets which aren't compatible, or possibly RAM which has gone bad.

I have a newly purchased macbook pro that came with lion, MC700, with 4GB of ram Default. I purchased CMSO8GX3M2A1333C9 from newegg to give me 8GB of ram. After installing the RAM, if i use the macbook for extneded periods of time the screen will hardlock, graphics artifacting is seen on screen and it beeps, causing me to hard shut down the unit. This is most noticeable when using Youtube HD or watching a DVD movie. I ran apple hardware diagnostics and it says everything is fine, I also ran memtest overnight with no errors. Thinking this might be a corrupt lion install i reinstalled clean and still get the issue. I bootcamped windows 7 x64 onto the unit and it will BSOD and hardlock just like lion would. I used the Windows Memory Diagnostic tool and it said no errors. My return time has expired for both the macbook (purchased at a best buy) and the RAM (from newegg). I know i can contact corsair but I dont know if that will even help, any ideas? My system is up to date with the newest updates as well.

I forgot to put that in the OP, when putting back the 4gb stock it works fine, but doesnt solve my issue. THe ram tests fine, is the MBP just that picky? I know i can RMA with corsair but there really isnt anything wrong with said ram its like its overheating when the new ram is put in

Graphics Crashing with Premiere Pro CC after Yosemite Upgrade

Hi There
I am having a lots of graphics crashing since upgrading to Yosemite.
It is particularly bad in Premiere Pro, Photoshop and After Effects.

Airplay mirroring lag after Yosemite upgrade

Hi All,
I've upgraded my OS to Yosemite recently and since then been having constant issue on mirroring contents (audio and video) from my Mac to Apple TV 3G. Everything works just fine before this and i don't know what else i should do to fix it. I've restarted all devices, restored Apple TV and reset my wireless connection and have all latest updates being installed. Appreciate your help. Thanks.
Ash

Fixed after reboot?
I also have the same problem with my MBA 11" 2010 late(official notes said 2010 MBA is not support), I'm pretty sure my MBA are works with my Apple TV before Yosemite, now is not work, both of the firmaware are the latest one,
PS. other 2 Macs are working well with OSX 10.9 with the Apple TV.

Macbook pro slow after yosemite 10.10 update

I updated my Mac book pro 2010 from mavericks to yosemite. And now it is so slow it will take 20 minutes just to turn on to the login menu. If i turn the laptop off for a couple of hours it seems to speed up a bit but then after 30 minutes or so it will start to freeze and take forever to load. Please help.

InDesign 5.5 & 6 AND Acrobat Pro crashing after Yosemite Upgrade

I've tried several of the fixes suggested however my InDesign is still crashing when I try to SAVE or EXPORT. I copied the files I need right away to work on into Illustrator. Converted the files to PDF's. Went to create a PDF file and I'm getting the same crash report that I get from InDesign. I'm getting desperate. Can someone please help?
I do not have any 3rd party FONT programs, everything has come from APPLE or ADOBE. I've done the CMD+CTRL+OPT+SHIFT command AND we've deleted the Recovery Files. Short of taking my computer to APPLE and have Mavericks reinstalled, I'm pretty lost here. Thanks for your help!!

You didn't actually re-flash your BIOS, did you? Yes
If it was fast before the infection, and slow after the reformat, then this is pretty much the only place that anything could be different. I'd be more inclined to test hardware than continue chasing software, in your shoes.
Ran various RAM tests, and the BIOS shows nothing out of the ordinary.
But it's certainly nothing to do with the software, unless the new install was botched for reasons having nothing to do with the virus, or that the virus is actually hiding in one of the spots on the motherboard that can be written to, like the BIOS.
Clear one thing up for us - you say
Adobe Software: Originally CS3 Suite, now CS5 Suite
Does that mean "it ran like a dream with CS3, but now that I have CS5 it's running slow?" Because, if so, you're chasing a red herring - CS5 consumes a lot more in terms of computing resources than does CS3. You should be looking at how to tame CS5's resource consumption, and there are plenty of threads about that.
After the reformat, CS3 Indesign was a dog as well as Acrobat 9 Pro. Upgraded to new CS5 Suite (all but Acrobat 9 Pro). CS3 & 5 Indesign still a dog as well as Acrobat 9 Pro
Lastly, I haven't seen malware hiding in flash ROM on the motherboard more than once in the last decade. It wouldn't generate any error messages or beep codes, either.
Same here, have not witnessed malware/viri infultrating the BIOS since back in 99'. Never the less, it's the only idea I can come up with. I have yet to locate any software for testing the NVIDIA NVS 290 video card. This is the strangest issue I have seen ever.

Macbook air issues after yosemite upgrade

Since upgrading to Yosemite I've been getting the pinwheel of death more often. I have to perform a forced shutdown and now my MBA is stuck on the Apple screen half-way through the progress bar.
How do I get past this progress bar?

Resetting SMC as well as NVRAM could solve the problem.

After upgrading iPhoto on my MacBook Pro running OSX Yosemite 10.10.3 it continually keeps asking me that it is preparing library. This has happened 5 times now and I can't access my photo's through iPhoto, any suggestions?

After upgrading iPhoto on my MacBook Pro running OSX Yosemite 10.10.3 it continually keeps asking me that it is preparing library. This has happened 5 times now and I can't access my photo's through iPhoto, any suggestions?

There is no upgrade to iPhoto with OS X 10.10.3 - here was an update to version 9.6.1 a few months ago and Photo 1.0 was added with 10.10.3 - what software and which version are you having trouble with - iPhoto or Photos?

Graphics nightmare after Yosemite upgrade on Macbook Pro and iMac

I have upgraded my 2013 iMac and my 2012 Macbook Pro Retina to Yosemite.
I am getting endless graphics glitches and crashes on both machine on all programs.
I've attached a screen shot from my Macbook Pro today.
I have updated the NVIDIA drivers on both machine and no difference.
Any help appreciated as I don't want to revert back to Mavericks (which was perfect)
Thanks

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off by the complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can act on it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of the script have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.

Copy the selected text to the Clipboard by pressing the key combination command-C.
8. Launch the built-in 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.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report what happened. No harm will be done.
12. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.
14. This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.
