Back up all data before making any changes.
Step 1
Take all the applicable steps in this support article. If you're running OS X 10.8.4 or later, run Wireless Diagnostics and take the remedial steps suggested in the summary that appears, if any. The program also generates a large file of information about your system, which would be used by Apple Engineering in case of a support incident. Don't post the contents here.
Step 2
Run Software Update and install all available updates for OS X or your computer's firmware.
Step 3
If you're not using a wireless keyboard or trackpad, disable Bluetooth by selecting Turn Bluetooth Off from the menu with the Bluetooth icon. If you don't have that menu, open the Bluetooth preference pane in System Preferences and check the box marked Show Bluetooth in menu bar. Test. Continue if you find that Wi-Fi is faster with Bluetooth disabled.
From that same menu, select Open Bluetooth Preferences. If the box labeled Discoverable is checked, uncheck it. Click the Advanced button, and in the sheet that opens, uncheck the top three boxes, if any are checked. Click OK. Enable Bluetooth and test again.
If the application called "Bluetooth Setup Assistant" is running, quit it. Note: this is not applicable to OS X 10.9 or later.
Step 4
This step will erase some of your settings in the Network preference pane. Make a note of them before you begin, and recreate them afterwards. It may be helpful to take screenshots of the preference pane.
Triple-click the line below on this page to select it:
/Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist
Right-click or control-click the highlighted line and select
Services ▹ Reveal
from the contextual menu.* A folder should open with "com.apple.airport.preferences.plist" selected. Move the selected item to the Trash. You may be prompted for your administrator password. Recreate your settings for Wi-Fi in the Network preference pane.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
Go ▹ Go to Folder...
from the menu bar, paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return.
Step 5
Reset the System Management Controller.
Step 6
Make a "Genius" appointment at an Apple Store, or go to another authorized service center.

HT1338 why my mac air is disconnecting from wifi automatically

The wifi is not connecting automatically even if it is a known network.
This happen when ever the laptop is on back after sleep or restart or shutdown.

Hello Yagna sundar,
Thank you for the details of the issue you are experiencing with Wi-Fi on your MacBook Air. I would be concerned about this too.
I recommend following the steps in the section labeled, "Symptom: The network connection drops unexpectedly" in the following article to resolve an issue like the one you described:

Thank you for posting in the Apple Support Community.

Why does my Apple TV disconnect from the internet while Im watching Netflix? If I reboot my Apple TV, it seems to stay connected longer, but it still disconnnects me from my Wifi every 10 mins or so. I am not connected thru the eathernet cable.

If you try by Ethernet you can verify if the issue is with your WiFi network or if your appletv is defect as most users do not suffer as you do

Some users with various Wi-Fi problems have reported that they were given the following instructions by Apple Support, sometimes with success. After completing the procedure, you'll have to recreate all your settings in the Networkpreference pane. Make sure you know how to do that before you begin. Taking screenshots of the preference pane may be helpful.

Mac Mini - Wifi Issue - Not Finding Established Network

Purchased and tried to setup a late 2012 Mac Mini (2.3 Quad-Core).
Current Wifi Setup
- Cable Modem into Airport Extreme.
- Airport Extreme (Base) is pushing to (2) Airport Expresses.
- (1) of the (2) Airport Expresses is underneath the desk where the Mac Mini is located.
- The devices currently on the network include: (1) MacBook, (1) Apple TV, (2) iPads and (2) iPhones. Everything is connected to the network and running properly.
Issue
One of the first things I attempted to do when I started up the computer, was join my home network. I searched for the network, found it and entered in the password. The Mac mini would not accept my password (the password is correct), claiming either password was incorrect or the connection timed out. I went to the Airport Utility and noticed the Mac mini was not locating/finding the Airport Extreme (Base), but was attempting to connect to the Airport Express underneath the desk. An important note the Mac Mini and the Airport Extreme are approximately 20 feet apart.
Here are some the methods I used to attempt a fix:
I turned off the Mac Mini Wifi and reset all (3) routers.
I updated the firmware of all (3) routers, reset them again.
I updated the OSX to 10.8.2
I ended up loading the Airport Utility on my Ipad and taking it back to where the Mac mini was located. From the attached picture, you can see on the bottom the Ipad correctly showing the Network and the on top show Mac Mini still searching for the Network.
I ended up hooking the Mac mini though Ethernet using the Airport Express underneath the desk, which is a fix however that an issue if the wifi is not working.
I’m currently at work and will have a chance to work on the computer this evening, does anyone have a suggestion on how to fix this issue?
Thank you in advance.

Mountain Lion on Mac Mini - WiFi unstable for Internet Sharing

I have a Mac Mini Mid 2010 MC270LL/A previously on 10.6.8 and everything worked fine.
I have it plugged into a Plasma TV via HDMI and network via CAT6, but it also doubles as a WiFi access point via Internet Sharing.
Previously WiFi was secured via WEP, I don't recall if 10.6.8 had anything stronger, most likely not, otherwise I would have gone WPA2.
I have now done a clean install of 10.8. ie erase hard drive, boot from USB and lay down a clean install of Mountain Lion.
Software update downloaded a new Firmware, which has also been applied and rebooted.
Now I've set-up Internet Sharing, used same SSID (maybe should have picked a new one in hind-sight), but secured via WPA2 - the only option.
Previously my Macbook Air 13" MC965LL/A, had undergone the same clean install treatment via wipe, then boot from USB and install 10.8.
The Wifi worked flawlessly with Macbook Air on 10.8 connecting to Mac Mini on 10.6.8 (Secured via WEP), no drop outs, connected even after sleep.
Even the power nap feature worked really well, I was impressed that when I open the lid on the Macbook Air, I had emails already waiting for me.
Now with the Mac Mini on 10.8, it's a really sad state, constant WiFi dropouts, my File Sharing disappears, Screen Sharing stops, it's a real pain.
I'm hoping it's not the new firmware, I guess I'll find out when I restore to 10.6.8 and see how it goes.
Anyone else have issues with Mac Mini WiFi on 10.8 ?

This is the System log on the Macbook Air while sleeping - connected with wifi to Mac Mini under 10.8

Mac Mini wakes up from standby automatically

Hi,
My Mac Mini wakes up from standby automatically. Waking up via network is disabled and I use an Airport Extreme, a USB mouse (not from Apple) and a wireless Apple keyboard. OS X version is 10.5.8.
I have the Mac Mini since about 10 months now. Almost 1 month after I bought it, I had the this problem but thought I am doing something wrong or my wife has forgotten to turn it off
After a while it was OK. About 3 months later it startet waking up by itself again. I called Apple Care (although the 3 months support was over). They tried to help, but there was no progress. It waked up again and again. After about 1 month it was OK again without me having done anything, no installations, no system updates.
One week ago, the Mac found some updates at Apple and installed them. Since then I have again the problem! I contacted again Apple Care and again they could not help. They just want me to pay for an extension of the Apple Care package, although they could not help me in this case!
Now I want to try it myself getting support by people in this forum. I hope there is someone with experience about this case.
I am not much experienced with OS X, but I will try to answer questions that could help me resolve this problem.
BTW, I searched for a similar topic and found one ("My MacMini always wakes up from standby") but in that case the wake up feature is activated by the user. In my case this feature is deactivated, as mentioned above.
Thanks
Cheers

Hi,
sorry for the delay, but I was on a business trip.
@Bsteely: Sometimes it wakes up immediately because of loosing connection to the keaboard when I send it to sleep. I suppose at the beginning of the sleep mode it into sleep mode, the keaboard connection is closed, then the keyboard "thinks" there is a problem and sends a message to the mini and the mini just wakes up again showing that the connection to the keyboard was lost but established again! This even happened as I had unselected the checkbox "Allow Bluetooth devices to wake up this computer" in Preferences -> Bluetooth -> Advanced.
But there are also times when the mini does not wake up so quickly. It just wakes up after hours. I had a look at Console.app as you suggested. Very weird to me indeed Well there I found something like "Wake reason = OHC2" or "Wake reason = OHC1". Unfortunately I cannot find older logs there.
@Boece: Hi and thanks for helping!
Well, I will try the update as soon as I can. By now I have no external harddisk to first save my data before doing the big update. But I am going to buy one soon.
Well turning off the monitor is OK, but the harddisk can wake up anytime while the mini is turned on as the OS might need to do something from time to time. And I don't want my computer to consume electricity even if it is such a small one like the mini. I'm a kind of green dude (but not from Mars ). And the sleep mode is interesting for me as I have very often many different Internet sites and some applications running, so I don't need to close them before turning off and open all of them again when turning on the mini.
Regarding other IR devices: The only IR device now is the keyboard. I even took out the batteries and the mini still woke up over the night!
Thanks again for your support guys. Please let me know if you have any further information of ideas.
Cheers

Caught in a conundrum while trying to upgrade a Mac Mini (mid 2010) from Snow Leopard to Mountain Lion

Hi gang,
I am in a very frustrating position as I try to upgrade my Mac Mini (mid 2010) from OS X 10.6.8 Snow Leopard to whatever the latest version of Mountain lion is. The reason I am doing this is because the original hard drive died and the Mini sat there for 6 months before we decided to get a new hard drive and revive it.
I installed a new 500GB 7200rpm SATA drive and the problems began.
First I couldn't get Mountain Lion installed as a fresh OS installation (using both a USB drive and a DVD to no avail). It just wouldn't go. The grey Apple logo/loading screen would come up and just sit there doing nothing while the loading icon spun.
I then tried installing Snow Leopard (the OS that the Mini came with when it was new). After some messing around, that got done.
However, a peculiar thing happens when the Mini boots. Everything loads up into Snow Leopard, but although the mouse curser moves, I cannot click on anything or use the keyboard for 4-5 minutes. Then it just work (I am typing this on the Mini). This happens every time.
Now, when I updated to 10.6.8, I was able to load up the App Store and download the Mountain Lion install app. I clicked it and went through the initial copying of files and then the restart, but after the reboot, the grey loading screen would not progress. I rebooted again and held down the Option key to check out the available boot volumes, and all I saw was the installation DVD I had in there for Snow Leopard and a hard disk volume called "Mac OS X Installer."
So I booted into the Snow Leopard install DVD and opened Disk Utility to check things out. I did a verify disk and a permissions repair. Interestingly, the first repair I did gave me the message that the ACL was missing from Volumes and that is was fixed. I read something somewhere which talked about the Access Control List and mouse/keyboard issues. But who knows. When I boot back into the Mini as normal I am returned to the fully-functioning Snow Leopard installation, like nothing happened.
And now here is the kicker: it appears that the Firewire bus is hooped. In the Profiler, when I view the FireWire settings I get the message, "Warning: Unable to list FireWire devices." So I am pretty sure the one thing I cannot do is boot the Mini into target disk mode attached to my Mac Pro and installed Mountain Lion that way.
So to recap: I can't finish the Mountain Lion installation because the install won't continue after rebooting because there is something wrong with the underlying base system, which might be hardware (FW bus) related. I think.
Some things I have tried:
Resetting the SMC
Resetting the PRAM
Reparing permissions
Booting into Safe Mode (doesn't work)
Booting into Verbose Mode to observe what happens (I get the "Can't load the Bootcache.playlist" error, which I suspect is related to the screwed up FW bus)
Trying to boot using Internet Recovery (doesn't work)
Booting into Single User Mode and attempting the "fsck -y" etc. sequence to try and repair the ACL that way
So I am stuck.
I guess the question is, should I get an external HD enclosure and install Mountain Lion onto the hard drive that way and hope it works when I put it back into the Mini?
Any other ideas? I have spent a couple days ******* around with this is am running out of ideas...
Any advice would be appreciated!

Addendum: I read on a post here (http://forums.macrumors.com/showthread.php?t=420169) about removing some kext files in order to trick OSX into thinking that there were no FireWire ports.
I followed the instructions and removed from /System/Library/Extensions/ the following files:
IOFireWireSerialBusProtocolTransport.kext
IOFireWireAVC.kext
IOFireWireFamily.kext
IOFireWireIP.kext
IOFireWireSBP2.kext
I restarted and BAM...Snow Leopard booted crazy fast and the mouse and keyboard worked instantly.
The System Profiler says "No FireWire ports were found."
So this tells me that the FW port is probably the culprit and is messing up the installation.
So how do I hack the Mountain Lion installer and tell it to ignore the FW port, which is obviously quite dead? Or is there something I can do to the Base system that is similar?

I cannot get the new mac mini to wake from sleep and trigger the displays - this is the second mac mini I have had and both have had the same issues. It worked before on my macbook extremely well...

I cannot get the new mac mini to wake from sleep and trigger the displays - this is the second mac mini I have had and both have had the same issues. It worked before on my macbook extremely well...
Using 2 displays, connected via HDMI and thunderbolt
Been on to support a number of times now - is anyone experiencing the same issues?

BUMP.
I actually showed this to Apple geniuses when I took my computer to the apple store, and it's still here. In console it says:
kernel[0]: Previous Shutdown Cause: -128
I don't know if that's related or not, but maybe helps?

Try logging on to AIM on port 443 rather than port 5190.
Go to IChat in the menu bar > Preferences > Accounts.
Log out of AIM and then use the Server Settings tab
Set the port to 443(press return/enter(you might have to tick and untick SSL for 443 to stick)).
Log back in again.

Hi Guys,

What is the problem here so I can get Pictures onto my Computer. ,

Hi Noob Søren
There are a few things that are confusing in your question.
As far as I know, you dont have to install Time Machine on this OS as it is already installed for you. You only need to connect a hard drive to your computer via firewire or usb, click on the Time Machine icon, Open Time Machine Preference in the drop down menu and select a disk: your connected hard drive.
You can of course reformat this connected device, partition it into a few volumes to organise data if you so wish.
I find it strange that your mac's hard drive is divided into two volumes... perhaps this was created through bootcamp?
You can access the configuration of your hd through Applications/Utilities/Disk Utilities.
Clicking on one of the icons on the right hand panel will bring the details of the contents of your hardDrive and volumes. From there you can decide to erase a partition, reformat etc....
If your hd contains more than one volume, and one of them is empty, you could decide to remove it. Back up all your important data before doing so.
Hope this helps
