OSX Yosemite Wi-Fi: no hardware installed
Hi ASC:
I installed Yosemite about 2 weeks ago, and at first my wi-fi (at home & work) was working fine, but then about a week ago the Wi-Fi icon at the top of the toolbar got an "X" in the middle of it and when I click on the Wi-Fi icon it says, "No hardware installed". I tried resetting the SMC on portables with a battery you should not remove on your own (from another thread) but no luck. I've googled this, YouTube-ed it, but still no Wi-Fi back. Someone PLEASE help
I'm using:
OSX Yosemite
10.10.1
MacBook Pro (15-inch, early 2011)
Thank you.
In some cases, this issue is caused by a hardware fault. A loose connection, a short circuit, or a microscopic break in a solder joint may open and close depending on temperature, making the failure intermittent.
Test after taking each of the following steps that you haven't already taken. Back up all data before making any changes.
1. If you can connect to the Internet via Ethernet, Bluetooth, or a USB network device, make sure all available OS X updates are installed. If Wi-Fi is your only means of network access, skip this step.
2.. There are a few reports that the problem was solved by unchecking the box marked
Wake for Wi-Fi network access
in the Power Adapter tab of the Energy Saver preference pane. I can't confirm.
3. Reset the NVRAM.
4. Reset the System Management Controller.
5. Start up in Recovery mode. In the menu bar of the OS X Utilities screen, there's a Wi-Fi menu. Try to connect. If it works, select Install OS X. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade, so make a note of those before you begin.
6. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

I have a 2009 21.5 iMac with malfunctioning internal disk drive. I lost CS2 when I upgraded to OSX Yosemite. I want to install Lightroom. Can I transfer the Lightroom 5 software to an SD card and then download from that to my computer?
you need the installation files, not copies of installed programs.

OSX Yosemite installation problems :-(
Have downloaded OSX Yosemite and have tried to install at least 10 times and continue to get the message "An error occurred when preparing to install. Try running the application again" What do I need to do to complete this install? Tried to find a more applicable community but could not post there :-(
1. If possible, set the system clock as instructed here. If you can only start up in Recovery mode, see below.
Select Get Help Online. Safari will launch. While in Recovery, you'll have no access to your bookmarks, but you won't need them. Load this web page.
Triple-click anywhere in the line below to select it:
date 0801000014
Copy the selected text to the Clipboard by pressing the key combination command-C.
Quit Safari. You'll be returned to the OS X Utilities screen.
Select
Utilities ▹ Terminal
from the menu bar. A Terminal window will open. Paste into the window by pressing the key combination command-V.
Wait for a new line ending in a dollar sign ($) to appear below what you entered. If it doesn't appear, press return.
Quit Terminal to return to the main screen. Try the installation again.
2. If the date is correct, or if you still can't install after correcting it, see beow.
Start up in Recovery mode, launch Disk Utility, select the startup volume ("Macintosh HD," unless you gave it a different name), and run Repair Disk (not Repair Permissions.) If any problems are found, repeat. Then restart as usual.
If you don't already have a current backup, you must back up your data before you take the above step. You may be able to back up, even if the system isn't fully functional. Ask if you need guidance.
Directory corruption in a MacOS journaled volume is always the result of a drive malfunction. It's not caused by power failures, system crashes, or anything else. You might choose to tolerate such a malfunction once in the life of a drive. If it's repeated, the drive must be replaced, or there is some other hardware fault that needs to be corrected. Ignoring repeated directory errors will result in data loss. -
Problem description:
(MacBook Pro 15” late 2008, OSX Yosemite 10.10.2 installed, no pending updates) computer is running very slow - takes 2-3 minutes to open apps such as Pages, even when no other apps are open. Randomly freezes and becomes unresponsive, requiring forced power down. Randomly logs off. Removed Kodak AIO software via Clean My Mac2, but BonjourAgent still there and requesting access. Cleaned weekly with Clean My Mac2 and running Sophos AntiVirus. 2GB memory installed. Currently 169.99 GB available of 249.2 GB capacity.

Slow performance after installing Yosemite on an older Mac is often caused by inadequate memory. Although you can install the upgrade on a Mac with 2 GB of memory, experience has shown that at least 4 GB is needed for full performance.
Select About This Mac from the Apple menu. If you have less than 4 GB of memory, and your model has upgradable memory, install as much as it can take, or at least that much. Any reputable RAM vendor will have a web form in which you can select the Mac model and be directed to compatible parts.
Memory in the MacBook Air is not upgradable. If that's what you have, you should restore the previous system from a backup, or replace the machine. Ask if you need guidance.
The Etrecheck report clearly shows that SylvieRose has a Macbook Pro, not a Macbook Air and that there are only 2 GB RAM installed. The Etrecheck report can be very informative if one takes the time to examine it.

installed download of Yosemite and now have message saying "Wi-fi: no hardware installed" Also do not have a wi-fi icon on system preferences menu.
Is it in your applications folder (look in UTILITIES)?
If not, reinstall the OSX.

I have a MacPro5,1, Quad-Core Intel Xeon, 2 processors running at 2.4 GHz. I am running OSX 10.6.8. I installed Yosemite on another drive. When I choose Restart in Yosemite it shows my 10.6.8 hard drive. But when I click Restart in 10.6.8 it does NOT show my Yosemite drive. I used to know how to get the startup screen that showed multiple drives but I've forgotten it. How do I do that?
Press Option at startup.

I cannot find Boot Camp on my iMac (late 2013) with windows installed. So I downloaded it, but I cannot run it because of an error (x64...). I tried to use my USB stick with bootcamp installed but nothing. When I turn my iMac on it starts automatically with windows. I tried to search it, but I found only the setup and it doesn't work. How can I get back to my APPLE iMac? How can I use OSX?
Excuse me for the (maybe) uncorrect language, I speak Italian.Hello!
You can start your Mac up with the [alt] (sometimes [option]) key pressed and you will get the Startup Manager. -

make sure you downloaded the mac installer, not windows.

Can't Install OSX Yosemite on iMac Mid-2009 Stuck - No Recovery Partition PLEASE HELP
I had an old iMac Mid-2009 2GB on OSX Lion, which had been kept away in the garage for a while. Pulled it out, ran Lion fine. It was going to be set up as a new computer, so I downloaded OSX Yosemite, planning to wipe and re-install after installation. Took a lot longer than I expected. After a while, the apple logo progress bar froze. I googled it and many people said just to wait it out, it could take up to 12 hours. 1 week later, still there. Fairly confident that nothing was going on on the hard drive. I reset the PRAM, didn't help. So I tried another fix I found which involved booting into the recovery partition. Guess what, no recovery partition . So finally I went to the trouble of creating an install usb. Booted fine, so I went into Disk Utility to erase my hard drive and re-install. But guess what, I couldn't! Can somebody please help! Or is this iMac stuffed?
Finally figured out the solution. My internal HDD appears to be not working after that faulty Yosemite installation. Just got a fast external HDD, plugged it into the iMac. Booted from the USB, went into Disk Utility and formatted it as Mac OS Extended (Journaled) in GUID. Installed and got up an running fine. Finally fixed this after 3 weeks! Hopefully this will help anyone that has the same problem.

I want to instal OSX Yosemite but told I can't
Check that your computer is compatible with Mountain Lion/Mavericks/Yosemite.
To check the model number hold down the option/alt key, go to the Apple menu and select System Information.
Mac Pro (Early 2008 or newer) model number 3,1 or higher -
After I upgraded my MacBook to OSX 10.9.1, the wifi does not work only the ethernet port works.
I check the WiFI setting, it complain with error message as follows "Wi-Fi: No hardware Installed".
Pls advise what is wrong and how to resolve.
ThanksFirst thing I'd do is shutdown the machine fully (that means use 'Shutdown' not 'Restart' from the menu), then power on.
If the problem persists, reinstall OS X from the recovery menu (power on, immediately hold down 'command-R' and choose 'Reinstall OS X' from the panel menu). -
