HT4628 My macbook pro will not automatically reconnect to the wifi after a sleep. This has started after having upgraded to mountain Lion (10.8).

Hi
After I have installed Mountain Lion (10.8) - my macbook pro will not connect automatically to my preferred wifi network. It used to do that on the previous versions. It seems that the mac does not recognize the preferred network, as it asks me to choose a network after evey sleep/restart. I have modified the network preference to have my preferred netwrok at the top of the list. I have tried with/without checking the "ask me before joining a new network". It still behaved the same.
Thanks
Eitan

Try making a new network connection and renewing the DCHP lease as detailed here:

HT4628 My MacBook Pro does not automatically reconnect to Wi-Fi after sleep

I have to manually Open Network Preferences and choose my home airport (or office network) every time that I wake up from sleep. I would like to have it automatically choose the network. Is there any way to fix this?

Not I solution, but I am hoping a similar issue to provide more insight. I am seeing your auto-connect issue, but I only seeing the issue on the first network listed in the preferred networks. I recently switched the order of of my preferred networks, and the auto-connect failure was immediately switched to the "new" first network.
To elaborate, I have never had issues with my home network. However, a few days ago I switched my home network to the top of my preferred networks list. Now I must always select my home network to connect. Also, I was always having problems with my parent's network, which was first in the preferred networks list. Now that it is second, I have no problems connecting to their network automatically, when waking from sleep or from a clean boot.
I am still searching for other similar reports of this issue.

My MacBook Pro will not connect to my home wifi but will connect everywhere else. My other Apple devices (I-pad, I-touch, another MacBook Pro) connect to the router without problems. It was working fine but all of a sudden stopped working.Thanks!

try this.
get back into your router's settings and start deleting devices that are not connected to your router.
you can also delete the ones that are connected - they'll connect again.
on the DHCP side of it, increase the amount of users that can connect/log in to your router.
see if that sorts it out for you.
good luck.

Because in my macbook pro will not let me open The Sims 3?

because in my macbook pro will not let me open The Sims 3?
Whenever I try to open the application icon starts jumping and then disappears

Says it works with 10.7, problems with 10.8 though.
Reinstall the program and trash the Dock icon, then make a new one and see if that works.
Then Trash it's preference file and relaunch the program to create a new one
Deleting the System Preference or other .plist file
If not then run through this, could be a sign of something bigger

When I create a new mailbox, it does not appear in alphabetial order. It appears at the bottom and I have to manipulate it to get it in its proper place. This apparently started when I upgraded to Mountain Lion. Any ideas?

Do you know why new mailboxes I create do not appear in alphabetical order? They appear below all other mailboxes and I have to manipulate them into their proper place. This apparently started when I upgraded to Mountain Lion. Any help would be much appreciated, as it's annoying and time consuming.

My macbook pro will not turn on and the charger is not lighting up

please help!! my macbook pro will not turn on at all, when i plug in the charger it will not light up at all, it suddenly shut down when i was using it.

Is there any charge left in the battery?
Press the button on the left side, near the front edge. If no green lights appear, battery is flat. And if the power brick ain't workin' (by virtue of its pilot light not glowing), then it will remain flat and the computer will not power up. If this is the case, maybe try with another power brick of similar size and see if it charges.
Else the logic board is toast and pitbull's on the money.
Either case, my gypsy crystal ball forsees a trip to an Apple Store or a Service Provider in your future...

Macbook pro will not wake up using default wifi

I have to select the default wifi each time i wake up the system at home. When it wakes up it does not wake up with the default selected. My default wifi is the only wifi used.

Make sure you are using the most recent OS X update for the version you have. Run Software Update.
Then, go to System Preferences > Network, select Wi-Fi, then the Advanced... button. If more than one network appears, delete those that you do not routinely want to use with the "–" (minus) button. Press OK, then Apply.
If your MBP still does not automatically reconnect upon wake from sleep, delete the file
/Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist
... and restart your Mac.
To find that file quickly, select the above path (triple-click the line), control-click to bring up the contextual menu, and select Services > Reveal. Drag that file to the Desktop, or directly to the Trash.
This will completely erase your AirPort network preferences, requiring that you select your Wi-Fi network and authenticate again.
If nothing else helps, try turning off Bluetooth if you do not require it. BT interference was suspected in preventing automatic reconnections to preferred networks upon wake from sleep, though this was never confirmed.

Macbook Pro will not reliably connect to our wifi router - any suggestions?!

Hi
My partner has recently bought a second-hand (but fully functional) Macbook Pro running OS X 10.5.8 to set up in our home office.
Our wireless router is not in the same room (it's in the living room via the hallway) but no other computer or device in the house has any problems detecting and connecting to the router.
My partner's pc netbook and my iPhone 4S connect fine all through the flat. My iMac (located in the office) also has no problems.
We have managed to get the Pro connected to the internet wirelessly a couple of times in the living room (although not all the time) but as soon as it is moved into the office the connection cannot be found or successfully connected to.
Can't help but think that there's some little setting or something that we've not done that is causing the problem - seems odd that all the other devices connecting have never had any issues! I'm not completely technically minded, but have had enough experience with computers to feel fairly confident on them - just wondered if anyone might be able to suggest anything?
The Network Preferences pages don't seem to be any help to me - I've tried several things in there that would usually help to rectify a troublesome connection.
Any help or advice would be so much appreciated - my partner bought this Macbook Pro to replace her netbook and a reliable online connection is paramount as she is designing websites etc. with it!
Thanks,
Jimbanzee

Hi JohnTh
Thanks for your suggestion (and apologies that it's taken forever for me to try this out and get back to you)!
I think I've done what you suggested but I think my lack of computer knowledge is letting me down as it did not work.
I went to Network in System Preferences whilst connected to the internet via Ethernet cable, and managed to connect to my router, I then locked the changes, removed the cable and then restarted but straight away upon logging in, it had lost the changes and was unable to find the wireless connection.
To be honest, it will not always find it when the ethernet cable is plugged in - in fact, I've witnessed it go from green light connection, having found the router and getting an ip address to amber without the ip address to not being able to locate the router (all whilst still plugged in on ethernet) within the space of about two minutes!
I'm a bit hazy on the details of your suggestion when you say:
Go to the wireless setup from here, and change the name to something that you can recognise. Make sure that it is password protected. Save it so that it'll write itself to its flash memory (your network will briefly not work).
I went to the Network page of System Preferences straight away - is there somewhere else I should do the wireless setup? Our wireless connection is (as it is on my iMac which connects fine wirelessly) protected with a WPA2 Personal password.
How do I save it so that the setup will write itself to it's flash memory? Sorry not sure where this is!
I have also tried to remove the 'remembered' network from the advanced airport settings using the '-' button and then adding it '+' back in, but this also does not seem to work.
We are planning on upgrading the operating system from 10.5.8 once we can get a secure connection - my partner is happy that she can connect to the internet via Ethernet cable but she is wanting to sell her PC netbook (in order to part fund the purchase of the Macbook Pro) and she's not happy to do so until she can connect wirelessly successfully!
Finally, thanks for all your help and suggestions - really appreciate it and hope to find a solution!

MacBook pro will not charge even when the charger is plugged in and working

So this is a strange one.
I have been using my MacBook pro for a lot of film editing and motion graphics. Recently, I noticed that my battery kept going down, even when charging. I thought nothing on it and kept using it. After around 4 hours, the battery went from 90% to 23% WHILE plugged in. This got me nervous. When I plug in the MagSafe charger, the light comes on and I get the "charging" symbol in my toolbar. The light turns orange and then, after a few minutes, the power starts to go down instead of up.
I have had this laptop since Christmas 2012 and this has never happened before. The laptop does charge, but only when I am running no application, when the screen is shut or when the laptop is powered off. Bear in mind that right now, I am on Firefox, that is the only application open, yet the charge is still going down. I assumed it was because I was using Premiere CS6, After Effects CS6 and Cinema4D, but now even when they are not open, the batter will not charge when I am using the laptop.
What is going on? Is in the charger? Any help would be greatly appreciated and I am starting to stress!
Thank you everyone for reading,
-Rory Campbell
UPDATE: I am currently only running Firefox and Finder. Now the laptop is charging as usual. However the second I open up Premiere, After Effects etc, it goes down. I have no idea what is going on!

Try resetting the PRAM and SMC. If you don't know how to, don't worry. They're very easy to reset. Just google how to do it. If that doesn't work, the only thing I would suggest is to take both the laptop and the charger to your local genius bar to have them examined. If it's less than a year old, apple should replace whatever is wrong with it as long as it was a factory defect.

Macbook Pro will not stay connected to the internet

It appears that I am not alone in this problem, but none of the troubleshooting is helping.
There seems to be no trigger, but randomly 0-10 minutes the internet stops working on the Macbook. Sometimes restarting the wireless helps, most of the time it does not.
I know that my network/internet are working fine because all of our other devices stay connected with the Macbook drops. Is there a easy fix that I missed?
Thanks,
Mike

Please test after taking each of the following steps that you haven't already tried. Stop when the problem is resolved. Back up all data before making any changes.
Step 1
Take the applicable steps in this support article. The Wireless Diagnostics program 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
Disconnect all USB 3 devices. If you don't know which are USB 3, disconnect all USB devices except keyboard and mouse.
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. If you find that Wi-Fi works better with Bluetooth disabled, you should use the 5 GHz Wi-Fi band. Your router may not support it; in that case, you need a new router.
Step 4
Open the Energy Saver pane in System Preferences and unlock the settings, if necessary. Select the Power Adapter tab, if there is one. Uncheck the box marked
Wake for Wi-Fi network access
if it's checked.
Step 5
Open the Network pane in System Preferences and make a note of your settings in the Wi-Fi service. It may be helpful to take screenshots of the various tabs in the preference pane. If the preference pane is locked, unlock it by clicking the padlock icon and entering your administrator password. Delete Wi-Fi from the service list on the left by selecting it and clicking the minus-sign button at the bottom. Then recreate the service by clicking the plus-sign button and following the prompts.
Step 6
In the Wi-Fi settings, select
Advanced... ▹ TCP/IP ▹ Configure IPv6: Link-local
Click OK and then Apply.
Step 7
Reset the System Management Controller.
Step 8
Reset the PRAM.
Step 9
Launch the Keychain Access application. Search for and delete all AirPort network password items that refer to the network. Make a note of the password first.
Step 10
Make a "Genius" appointment at an Apple Store, or go to another authorized service center.

2013 Macbook Pro will not reliably connect to home WiFi.

This problem began about a month ago. I've owned this computer for 2 months and had no problem the first month. Now, when I turn it on it searches for the wifi signal and my wifi's SSID is visible but it doesn't connect, even when I select it from the list. It stops searching and the ! icon appears. If I restart the computer it will usually connect then automatically but at times I've had to restart it 2 or 3 times before this happens. And it can happen multiple times each day if I shut down the computer. At times though it works normally so the problem is intermittent. My Iphone 5 has no problem connecting with my router. I believe this began happening about the time I added a Brother wireless printer. I also now occassionally get a message that there are 2 devices sharing the same IP address and don't know what that's about or if it's related to the problem. This is my first Mac (and first wireless printer) and I should also add that I consider myself a technodummy. Help in solving this perplexing and annoying problem would be greatly appreciated.

Not able to visualize the person I'm calling on Skype anymore, now that upgraded to Mountain Lion operating system. Any suggestions?

Right after I downloaded the new Mountain Lion OS, I was not able to see the person I'm calling on Skype. The person I'm calling has no issue with the video streaming, however. Is this a Mountain Lion issue, a Skype issue or some of each? From looking at the Skype site, it seems alot of other people are having similar problems with using all the functions of Skype since downloading the new OS.

Are you using the most recent version of Skype?
Also, if the person on the far end is using a Mac or an iPad, you may want to consider FaceTime. The video quality is scads better.

My Macbook Pro will not find or use the downloaded driver for my new Canon Pixma MX479 wireless printer

I have been fussing for hours with a Canon Pixma MX479 printer I received as a gift. The printer was obviously designed for PC control, and has terrible instructions for setting up the wireless capability, but I finally found a few hints online about how to add a WPS printer to my Airport Extreme, so I can finally detect the printer. However, when I try to add the printer, either under System Preferences or while just doing a print, my MacBook requires that I download a driver from Apple to use it. When I attempt to do that, I get a message the driver software is unavailable from Apple and that I should contact the manufacturer for the driver. I have already downloaded and installed the Mac OS driver from Canon twice, but my MacBook apparently can't find it. So I am forced to use Airprint in order to communicate with the printer. I would like to use the proper software to make sure I am accessing all of the features the printer offers. Can anyone tell me how to associate the downloaded driver with my printer when I am attempting to add it?

Hi Dwntso!
Welcome to the Canon Forums and thanks for posting!
So that the Community can help you better, we will need to know any error messages you're seeing either on your computer or the printer, and the version of OS X you've got on your MacBook as well as the way you intend to connect to your printer (USB or networked via WiFi or Ethernet).
Any other details you'd like to give will only help the Community better understand your issue!

Thanks and have a great day!

MacBook Pro will not accept anything in the disc drive?

I have tried every kind of disc possible about 10 times each. CD's/DVD's/Even PC Games. All on different discs every time.
My MacBook will only accept the disc for no more than 5 seconds, making a noise like it's trying to read it and then stops, and then reboots itself again, repeat 3/4 times and then ejects the disc out.
Previously it was having trouble ejecting the discs every now and then, but I just lifted the laptop on its side to help encourage it to eject.
I have tried the troubleshooting tests (shutting down, holding the D key) and it says that everything is fine. I'm worried my hard drive may be dead, but I don't see how when I have hardly any data on the laptop. 80% is all in a portable hard drive.

Possibly.
And how do I shoot compressed air into it… using a hairdryer on cool or something? (I'm hopeless at tech, sorry)
One can purchase compressed air in a can.
