Mac keeps freezing since upgraded to yosemite

since I have upgraded to Yosemite on my MacBook pro 2009 safari and chrome and many other apps that I try to run freeze and lock up the entire computer. If I wait eventually it will unfreeze. I have tried restarting several times. Could I have a virus?

Could I have a virus?
You could, your Mac can't.
It's infinitely more likely that your Mac contains incompatible software. Post an EtreCheck report to give us an idea of what is installed.

  • Preview opening invisible files and freezing since upgrade to yosemite

    I "upgraded" to yosemite and now preview more or less doesn't function. It started when I tried to open a locked document (which I had locked using adobe cs6 or cs5 I can't remember. Adobe can open it just fine (one page at a time) but preview can no longer open it. It'll open and then as soon as I scroll one page up the document freezes. and from then on out when I hover over the buttons for any document I open or have open in preview the close, minimize and full screen button do not change their icons to let you know you are hovering over them, but they still work. I can still minimize and close thing.
    Additionally, when I go to open any more, they open up a blank/see through window. I can see a slightly opaque box where the file should be but there is nothing there. And I can minimize this box of nothing, and close the box of nothing, but that's it. I have to quit preview and start/get stuck all over again.
    I have an early 2013 macbook pro with a dual core i7, 8 GB of ram
    Lastly, as a side note, that sound the reminders makes is awful.. It sounds like my computer has gas... *facepalm*

    I have similar problems. I used to be able to double click an item, such as a photo or Microsoft Word document, and have it open easily using Mavericks but Yosemite doesn't seem to work. I've tried changing the open with settings for .jpgs, etc. for each app but Yosemite changes all files to the same setting regardless of whether it's a Word document or a photo from Adobe. Running a MacBook Pro with Intel Core 2 and 4 GB memory.

  • Mail App keeps freezing and crashing after yosemite upgrade.  Cant create new emails.

    Mail App keeps freezing and crashing after yosemite upgrade.  Cant create new emails.  Is there a fix to these issues?

    Hi,
    When I read these Threads in Yosemite I am filtered to show only the one listing Messages (the App) as the App involved.
    This form of tagging a Thread no longer shows up in the current software used to run the Discussions.
    Did you use the Mail and the Messages tags ?
    It is difficult as many Mail help items refer to emails and "messages".
    With me posting to the thread it should raise it to near the top again and maybe someone who knows about Mail will post.

    Apple doesn’t routinely monitor the discussions. These are mostly user to user discussions.
    Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.

  • Since upgrading to Yosemite my macbook pro keeps going to sleep if I am not using it. I want it to stay on as I leave it doing things overnight etc. It was fine before the upgrade and I have all the system preference set to "never turn off"

    Since upgrading to Yosemite my macbook pro keeps going to sleep if I am not using it. I want it to stay on as I leave it doing things overnight (cd's  / recording etc. It was fine before the upgrade and I have all the system preference set to "never turn off" - Help !!!

    Good advice from Linc Davis that should sort out your query i think...
    However you dont want to set your MBP to never go to sleep...
    Adjust reasonable sleep settings...
    And the download an APP called caffiene...
    When you click it you can have your MBP never go to sleep with a single click of your menu bar... and with another click it can go to sleep normally to maintain the laptop...
    Simply click the cup... To toggle never sleep/sleep

  • Asked to Sign-in to iCloud every time I start my Mac since upgrading to Yosemite

    Since upgrading to Yosemite every time I start my computer it goes through the normal grey screen stage and then I get to login as normal. After logging in I then get asked to sign-in to iCloud. I sign-in successfully and agree to the terms and conditions, choose to upgrade to iCloudDrive and then it says setting up my Mac, which takes about 20 seconds before the desktop displays. I'd expect this behaviour on the first reboot after installing Yosemite but it's asking me to sign-in to iCloud every time I restart and taking me through all these steps!
    I'm on iMac, Late 2012, 2.9 GHz Intel Core i5, 8GB

    Just to say I never found a solution to this after hours of looking for answers and trying different things. I finally decided to take the plunge and reformat my hard drive and reinstall OS X Yosemite and now is all good on this front.

  • Since upgrading to Yosemite my iPhoto, iMovie and Garage band has simply disappeared from my Mac. HELP!?

    Since upgrading to Yosemite my iPhoto, iMovie and Garage band has simply disappeared from my Mac. HELP!?

    Hi Jdireen,
    As someone who uses the iLife applications on a daily basis on my Mac I can understand how it would be upsetting to have them disappear suddenly. Let's see if we can get you back up and running.
    You can download the applications again and reinstall them from the Mac App Store - 
    GarageBand - https://itunes.apple.com/us/app/garageband/id682658836?mt=12
    iMovie - https://itunes.apple.com/us/app/imovie/id408981434?mt=12
    iPhoto - https://itunes.apple.com/us/app/iphoto/id408981381?mt=12
    Thanks for using Apple Support Communities.

    Have you informed Apple of your problem?
    Yosemite sometimes has problems, often related to "default" permissions needing to be changed

    Can someone tell me why, since upgrading to Yosemite, I keep getting a message window saying "Another device on the network  is using your computer's IP address?"

    That may be what is a fairly common problem of 2 devices mistakenly assigned the same address. Try shutting off all of the devices connected to your router, reboot the router and then the devices connected to it.

  • Since upgrading to yosemite, my mail is so slow

    I use Apple mail app on my mid 2012 macbook pro, it uses sky yahoo mail, never was a problem with Mavericks.
    Now i open mail, it takes a long time to connect , send and receive mail, i have tried connection doctor, it does take a while and shows as connected, which it is.
    I  am using POP 3 and smtp
    please help !!!!

    since upgrading to Yosemite, not only is my whole computer very slow and tending to freeze, but Mail just won't function, and keeps throwing up a box every few seconds saying it can't connect. It's very difficult even to get Mail to quit. Basically, the whole computer is non-functional.
