After upgrading to Yosemite my wifi is not working on my 2011 MacBook Pro. What happened Apple? Wifi was fine on Mavericks.Yosemite was free. I guess you get what you pay for.

Why is my wifi not working after I installed Yosemite to my 2011 Macbook pro?

Keep it connected to the Power for a while.
Start up in Safe Mode.

Ouch, if it is indeed damaged, then sadly you need to restore the whole danged huge OS!
Didn't used to be this way before Lion/10.7.
Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.
If that doesn't help Reinstall the OS.

If a restore did not fix it, you have a hardware issue--possible bad wi-fi radio.

You need to get some software that allows your Mac to read and write to the NTFS disk. There's a whole bunch of stuff out there, but this program has a good review, and you can try it for free. I would move everything off of your external drive, reformat it into Mac OSX extended, and use it for your Mac. You don't need NTFS anymore, unless you still have a Windows computer that needs it.

I am a windows user that has converted to Mac and loving it but when I updated to Lion my wireless internet dongle would not work anymore and the Macbook Pro does not recognise the device at all so I am unable to reinstall it again. Any ideas

No third party applications installed; no gestures changed. It just starts acting up like I described a few times a day. I'll be browsing the internet and go to switch desktops and it suddenly doesn't work.

Can not shut down late 2011 MacBook Pro and turn it back on again without the hard drive disappearing?

Ok, I have searched for months for an answer to this question to no avail, probably because no one has experienced it before. I am hoping however that you guys can help me figure this one out cause it is driving me nuts! Also, I am not entirely sure what section of the support I should put this under so if I stick it in the wrong place, I apologize.
Right now my problem is very simple. When I turn off my laptop, and then try to turn it back on, my internal hard drive disappears... and I get the blinking folder with a question mark on it. I have figured out something interesting however. I have an install disk with Ubuntu Linux on it. If I boot into that first, then RESTART the laptop, not shut down and turn back on, it reads the internal hard drive just fine and I can boot as if there is nothing wrong.
Second part to the problem... If I allow the laptop in either OSX or Windows to go to sleep (aka shut off the hard drive but the computer remains on), when I attempt to wake it up, I am greeted with the usual log in screen of whichever OS I am in, but is frozen and after a few seconds goes black and restarts the computer to find that... Surprise! The hard drive is gone
I have tried every trick in the book that I can think of, but can not seem to come up with a solution to the problem... I know when the problem happened and if anyone thinks that that will help them figure this out I will type everything I did up till, including the crash that caused this, and my attempted fixes, but I have class right now so only if you guys want it I will type all that out.
What I am currently running is:
2011 MacBook Pro 13in screen
4Gb of Ram
1TB internal Hard Drive
OSX 10.11.whatever the newest update is... just updated the other day again.
Windows 8.1 on BootCamp 5 (yea I know its not supposed to work but it does) again, fully updated
Ubuntu 13.10 (I think? Doesn't really matter, its just an install disk I use to boot the computer)
If there is anything else that you guys need me to provide, I can, just simply ask. I can provide as much info as is necessary.

Sorry it took me so long to write back, But unfortunately this didn't help my issue.
My uncle and I did a lot of tests on this computer and have narrowed down the location of the problem a little bit.
We tried to first reset the SMC and the NVRAM as suggested, but the only thing that did was make the fans run on full tilt for the first session after restarting it for some reason. After that we tried re installing OSX over the OSX that was already on the system (not removing any of the files). This also didn't do anything but make refit stop working. Then we moved onto the next task at hand by removing the hard drive entirely and booting it as an external drive from one of the USB ports... as long as you booted it with the options key held down, it worked perfectly fine. Then we put an alternative hard drive into the computer and installed OSX on that. This time there was no trouble booting anything up. Everything seemed to work flawlessly. So we made a backup of my original drive (OSX, Windows, and all) onto an external hard drive and tested booting to it via USB. That again worked perfectly fine and booted right up with no problems. So after that we formatted the original hard drive and reinstated OSX. We then proceeded to transfer all the old files from the backup onto this new installation and LOW AND BEHOLD..... we were back to square one with it refusing to recognize the hard drive again.
So this basically told us that there appears to be something either wrong with the hard drive, or something got really screwed up in the software along the lines and by me copying all my old files back over, I just ended up bringing the screwed up file back over with it! (despite not copying over any settings of any kind) So I am still extremely confused as to what is going wrong... did some boot sector possibly get screwed up may be?

Christy,
Whats the version of your seeburger and whats the SP level of your PI 7.1
Just check the seeburger compatability matrix and see whats the supported seeburger version for PI 7.1 (your SP level).
We recently installed PI 7.1 SP 07 and the compatabile seeburger version was 2.1.0
for PI 7.1 SP 08 the compatabile seeburger version was 2.1.3
SAPNote 890721 is the seeburger compatability note , but SAP is currently updating it.
You can send a message to SAP and ask for the complete compatability matrix , they would be able to provide you.
Hope it helps ,
Gerard

Office for mac 2011 not working correctly on new Macbook Pro- Help

I have a MacBook Pro from September and had One to One transfer all files/programs (including 2008 Office). I then purchased the Office for Mac 2011 program and they installed it (I guess they did not remove the older program). It has never worked correctly and I have tried to contact Microsoft to no avail.
None of the documents open with Fonts intact (Word and Excel open up blank though the graphic elements show up. I have to Select All and choose a font to make it show up.
Powerpoint is barely functional (none of the layouts actually show up when I select them, the sidebar of slides does not update as I type or try to change themese, etc. And then when I type, the program freezes and then shuts down.
I have uninstalled 2008 and 2011 and then re-installed 2011 but the same issues occur. Someone on the microsoft community told me to remove my duplicate fonts, I ddi that and the same issues still occur. My brother has the same laptop and Office for Mac 2011 and no issues.
Can someone help me basically try to start fresh- should I uninstall again? (I waas told that installing/uninstalling too many times can further the problem).
Help!
Thanks,
Bernice

Why is Bootcamp is not working right on my MacBook Pro (No Bootable Device)?

      I am not a computer geek but I learned a lot through reading forums and other people’s experiences. I want to use Windows 64bit in order to work on an Architecture portfolio using AutoCAD, Revit, 3DS Max, Sketchup, Photoshop, and Illustrator. I use these programs at school and on a PC and love it. I want to use these programs at home but wasn’t confortable with the Mac version so I had Windows installed on Parallels but even after upgrading my RAM to 10GB my computer was quite slow so I rather work on my projects separate from my Mac side (also, would feel less distracted) and set up Windows on Bootcamp, but I’ve encountered some issues.
        I wasn’t planning on partitioning my hard drive until after updating to Mavericks. Then I noticed I did not have the option to create a Windows 7 install disk so I reprogrammed the info.plist for the option to appear. After following all three steps, the computer restarted with a black screen that read “No bootable device – insert boot disk and press any key”
-Pressing any key didn’t help so I restarted and held the alt/option key until the booting options popped up and only got
     -Macintosh HD
     -Recovery HD
-Did not get a Bootcamp boot option so I repartitioned the hard drive to a single volume and repeated several times and still the same thing
-I tried using Disk Utility to partition, but the results were the same
-I tried using a different Windows7.iso file and still the same
-I also tried a 2.0 and 3.0 USB thumb drive for the .iso file
-Bootcamp Partition shows up on my Finder window on the side tab under ‘Devices’ and shows up on Disk Utility, but not on Startup Disk and not when I start my computer and hold alt/option.
-I did not plug in the Windows Support Software at all (I read somewhere that said not to plug in until after Windows partition boots and installs, but didn’t even get to that point)
-Had no CD nor USB plugged in other than the flash drive that carried the .iso
-I read a comment that said to copy the files bootcamp made (WINISNSTALL) to the ‘root’ of the flash drive, but that I see they are already on the ‘root’ (unless I don’t know what root is?)
-I also tried reformatting the partition on Disk Utility from MS-DOS (FAT) to Windows FT Filesystem but fails every time
-I also made a backup, and restored the computer (took hours!) and repeated everything
-After trying almost everything, I still get the “No bootable device – insert boot disk and press any key” message.
When it gets to reformatting, I have no idea what I am doing, the only reason I am trying all these methods is because of what I read on other peoples success stories and comments, but its either my computer does not work, I am missing something, or I’m not geek enough.
-Just to let you know, the first .iso I had worked on Parallels but not for Bootcamp
-I don’t think this matters but I am trying to partition my 320GB hard drive at 70GB for the Windows side. The only thing I will be installing would be the architecture programs while my projects and files would be saved on an external hard drive.
-Computer is up to date at version 10.9.1
-MacBook is from Early 2011, 13-incher
-The only method I could think of that I did not try was using a DVD to create an .iso disk because most comments said USB gave the best results.
-Should I use my Hitachi 250GB External Hard Drive 2.0 instead of a USB Sandisk 16GB 3.0 and Verbatim 4GB 2.0
PLEASE HELP ME ANY ADVICE WOULD HELP!! And Happy Holidays!

Your post is incredibly hard to read, font is way to small.
If you used Boot Camp Assistant to create a partition to install Windows to you need a REAL Windows 7 or 8 install media and license key and you have to actually install Windows on your Mac. Boot camp is only for creating a partition to install Windows and starting the Windows install from REAL Windows install media.
That Windows install media has to be a DVD disc, if your Mac has a built in DVD drive (Apple does not allow Windows to be install any other way on Mac computers that originally come with a built in DVD drive), or from a USB stick with the actual Windows install files on it (Not an ISO of the Windows install files).
So the question is did you install Windows on your Mac? It doesn't look like it from the Option key boot and the list of available Boot Devices you posted.

Trackpad not working on brand new Macbook Pro 15" not retina,

I've just got from UPS my new Macbook Pro 15" not retina. It's the basic model, without upgrades.
I've plugged it in and turned it on to go through the setup assistant, but I had to do it with the keyboard and an external USB mouse, because the internal trackpad is not responding at all. Is it normal?
Thanks!

That was the first thing I did. They told me that it was normal, but I don't believe them. They told me to wait until installation was complete and perform updates, and try after that. That's what I'll do, but I suspect I'll have to have it replaced.
Right now I'm migrating my old mac to this one. I'll update as soon as migration is complete.
