IMac Retina 5K - Yosemite 10.10.2 - Update has killed my WiFi! (Before everything worked fine on 10.10.1)

Hello,
URGENT HELP NEEDED !
Imac 2014 Retina 5k with 4ghz Intel Core and 16GB Ram
Router : Netopia
Have upgraded this morning my iMac Retina to Yosemite 10.10.2. Before upgrade Wifi worked great, now since upgrade, I lose the wifi connection after a few seconds ! To get it back I have to (a) Reset the router (b) delete the wifi network from Network settings (c) restart my iMac
I then get the internet back for a period going from 20 seconds to about 5 minutes max!
In the router log I see on he MAC address of the iMac the computer connect itself, and then I see a message that says "Suspect Connection" and then another for the MAC address of the iMac being "Connection closed".
No tempory fixes work! I have discussed this with my internet provider (Swisscom) and they have done everything they can do on their side (change router channels etc...) but to no avail. They say this is an Apple issue.
I am going crazy !
Any solution is welcome ...
All the best,

I can't send emails from Mail. I have three different accounts set up and have the same problem with all. The mail just sits in my outbox. All worked fine until Yosemite upgrade. Recent update has not fixed problem.

I have been experiencing the same problem. My mail app won't even open on my Late 2011 Macbook Pro. It will show as open, but the app will never actually show up.

HT4623 My iPad 3 has lost the speaker sound after updating to iOS 6.1, headphones are working fine

My iPad 3 has lost the speaker sound after updating to iOS 6.1, headphones are working fine. Please help me out, done all the troubleshooting like restarting, side switcing, cleeaning the headphone jack etc.,

Hi I also have this problem. Sound was only working on the headphones and also on the volume slider in the settings app. Everywhere else I get no sound and no volume slider. Now the headphones don't work either.
(I'm using an ipad 2 iOS 6.1.2)
And NO it's not muted. I've reset all settings and restarted the iPad. Been searching forums for a couple days. Some say its a dirty docking port problem, others suggest a Skype or other app update that could be the problem.
No volume control icon appears when I press the volume control buttons. Only says sound effects, if it says anything at all. Most often there is NO volume icon. YouTube, video, music, and other game apps, no sound.

Recent Windows 7 Update has killed windows

Help, I run Windows 7 in Bootcamp, recent windows 7 update has killed windows, this is what happens.
Choose to boot to windows - OK
Hit logon screen - OK
Logon - OK
Windows loads, the desktop shows for about 5 seconds and then the screen goes blank.
The computer is still ON but the screen is blank.
I can boot into safemode OK, but can't run the bootcamp update (that I downloaded from here) in safemode.
I tried a restore point, but the ones before the update create an error, so thats a no go.
My thoughts are that it is a video driver issue, but that doesn't explain how it gets passed logon working OK.
I don't know how to fix this if the only way to update drivers is via an .exe vs the driver files themselves like windows usually likes.

You could try this advice from the Windows side.
Startup Repair is a good place to start if your system starts acting up. If you can’t get the Advanced Boot Options screen by hitting F8, you can also access the tools by booting from a System Recovery Disc, or the Windows installation disc. While System Repair might not be able to recover your system in all situations, it’s a great starting point before getting into more detailed recoveries like Restoring from an image or clean install.

Temporarily disable/turn off your anti-virus and firewall software and try the download again.

Try resetting your iPhone ... but first, make sure it has a well charged battery!
Hold the on/off and home buttons together for 6 or 7 seconds until the Apple logo appears.

It sounds like it is time to restore from the backups you made just before making the disk changes.
You can re-partition and restore your backups. If you didn't make backups first (you were warned that it might damage things and to make sure you had a good backup) then you will need to repartition everything and reinstall from scratch...

Some users have reported as many as 8 or 9 attempts were necessary before success.
Be sure to Follow ALL the Steps...
But... if the Device has been Modified... this will Not necessarily work.

After updating to Mavericks from Snow Leopard, everything works except iPhoto. If I buy the current version of iPhoto for $15, will it work on Mavericks?

After updating to Mavericks from Snow Leopard, everything works BUT all my photos were lost. If I buy the current version of iPhoto for $15, will it run on Mavericks?

If you have iPhoto from iLife '11, then I would first install it on your computer. In that way you would be able to get the new iPhoto free since you are running Mavericks.
iWork and iLife for Mac come free with every new Mac purchase. Existing users running Mavericks can update their apps for free from the Mac App Store℠. iWork and iLife for iOS are available for free from the App Store℠ for any new device running iOS 7, and are also available as free updates for existing users. GarageBand for Mac and iOS are free for all OS X Mavericks and iOS 7 users. Additional GarageBand instruments and sounds are available for a one-time in-app purchase of $4.99 for each platform.
The iWork apps are free with a new iOS device since 1 SEP 2013. They are free with a new Mac since 1 OCT 2013. They are also free with the upgrade to OS X Mavericks 10.9 if you had the previous version installed when you upgraded.

Yosemite 10.10.2 update has slowed down my iMac and Macbook. Anyone else have this problem?

My iMac and Macbook were operating well until the Yosemite 10.10.2 update. Now, the wheel spins when I try to scroll down on pages, or when I try to move from screen to screen. Programs freeze up more often, needing to be forced to quit, or just crash altogether. Safari has been particularly affected. Both computers are only 6 months old. I close all other programs and Safari tabs, but this does not help.
(iMac 2.7 GHz Intel Core i5, Memory 8 GB 1600 MHz DDR3; specs on Macbook not handy as I post this.)
I have come to dread OS X updates and I'll be careful about downloading them in the future. I am becoming more and more disappointed in Apple as a whole. The last time I called Applecare for help was pointless. I learn more from forums like this.

I updated the Epson printer on my iMac OS X Yosemite 10.10.1 and my generic ink cartridge does not work.

On my iMac OS X Yosemite 10.10.1 I updated for my Epson Stylus NX420 and my generic ink cartridges no longer work. Can I delete the update?

Can I delete the update?
You might be able to revert back to the drivers you have before you upgraded if you have a backup of your hard drive made just prior to the update. But I'd try the Reset Printing System first.
If you do have a suitable backup go to the HD/LIbrary/Printers folder
and copy the EPSON folder to your Desktop.
Find the same folder on your boot drive and replace it with the one from the backup.
Also go to the backup's Users/Home/Library/Printers folder and copy the Epson app for your printer to the same folder on the boot drive.
I have an Epson R280 printer.
Finally reboot, repair disk permissions and try again.
The above is what I had to do when I upgraded to Yosemite.

Why does my retina MBPro and the projector go blank, when connecting with HDMI? This worked fine until the latest OS and firmware update.

Connecting through HDMI worked fine, until the recent firmware update and the 10.7.5 OS update. Now, both retina display and projector dosplay go blank, with the screen coming back when unplugged from the projector.

Clone your system.
Never apply updates w/o one.
And yes there is a page with all the Apple Downloads to do manually and then you can keep it on hand. Same for the OS X Lion or ML installer - save them before running. Still on 10.6.8 so you have OS X 10.6 DVD.
Combo updates do not do any harm. There could be issues to the drive directory beforehand.
Mac Pro has been shipping with Lion since summer 2011, though you can even now still reinstall iwth 10.6.4+

Can not update software on my iMac as it says it can't connect to internet when internet connection is working fine.

- i have made another admin account and tried to update software here, this does still not work.

Try:
iTunes for Windows: iTunes cannot contact the iPhone, iPad, or iPod software update server
Also try change the DNS to Google's servers. See:
