Why does the internet on my new macbook pro not work when my old macbook's does?

Why does the internet on my new macbook pro not work when my old macbook's does? I'll have to turn the wifi off and back on multiple times to get the internet to continue to work on my Macbook Pro (running mountain lion but did it on lion also) when it runs fine on my old white Macbook (running lion). Is there something I can do to fix it or do I just have to deal with it?

Here is your fix .. I have uploaded my properly calibrated profile get it here :
http://www.megaupload.com/?d=YAJL6A9X
And it should go to your user folder/Library/ColorSync/Profiles
if you have one already you can rename either one ..
and then go to system preferences - displays - color to select the profile .
you will get rid of the blue tint while keeping correct color and gamma
This is for the newer 2010 MBP's altho if same display was used might also give good results in the previous models as well . .

Macbook pro not working without battery

my macbook pro not working if i remove the battery
& if the battery is empty my macbook pro not working before charging

Try an SMC reset:

You should not run on AC with the battery removed. The MBP should work that way, but the OS throttles back the CPU so running like that is not recommended.

IChat disconnects when external monitor connected to Macbook Pro.

Downloaded latest OSX patch last week (Thunderbolt patch). Now, when connecting my HP external monitor to my Macbook Pro (2011), iChat will only stay connected for 2 to 3 minutes. If I disconnect my external monitor, iChat will stay connected all day long. This just started last week after loading the latest SW upgrade. Any ideas?

Hi,
I am not going to be much use here.
I don't have a computer with Thunderbolt.
The computer I do run a second screen on is a G4 running Leopard and in the Energy Saver there is no setting for the second screen to be set independently than the main screen.
I think it may pay to ask again in the Lion Forum Community.

Bluetooth from iPhone 3GS to MacBook Pro not working?

I am having (seemingly) bluetooth connection issues with "some" devices to my MacBook Pro. I note:
* Mouse pairs fine
* iPhone 3GS does not remain connected (focus of this forum question)
Error - after pairing my iPhone 3GS to my MBP I get an error:
The Bluetooth Network is Unavailable
There was an error connecting your device. Make sure the device is turned on and in range.
Notes:
* MacBook Pro details:
Model Name:          MacBook Pro
Model Identifier:          MacBookPro6,2
Processor Name:          Intel Core i7
System Version:          Mac OS X 10.7.3 (11D50b)
Background: Ultimately interested in teethering my iPhone 3G data connection to my MacBook Pro, but for the moment the bluetooth connection won't even remain in place.

nothing in these articles helped unfortunately - some more clarification:
tethering via USB from iPhone 3G to MacBook Pro => WORKS
tethering via Bluetooth => does NOT work, with bluetooth connectioning not staying up
During pairing process:
devices "see each other"
pairing appears to work, then you see that the connection drops out directly afterwards (almost immediately)
on iPhone message = "Connection Unsuccessful - XXX's MacBook Pro is not supported"
on MacBook - it's just the connection in Bluetooth options shows up as not connected
in /var/log/system I see some bluetooth related lines:
Apr 18 19:33:14 Gregs-MacBook-Pro bnepd[18950]: [IOBluetoothDevice instantiateChannel] BluetoothHCIAuthenticationRequested failed (0x0006), so retry
Apr 18 19:33:14 Gregs-MacBook-Pro sandboxd[18966] ([18950]): bnepd(18950) deny mach-lookup com.apple.blued

Apr 18 19:33:53 Gregs-MacBook-Pro blued[22]: Removing Bluetooth configured device: 00-26-08-23-23-9d
Any other ideas? Is it a physical problem with my MBP? but then again my bluetooth mouse stays connected ok. And in terms of the iPhone well it tethers fine to the iPad via bluetooth....

Need help one USB Port on MacBook Pro not working

Its been a weak now and im getting tired of my MacBook pro USB not reading anything.. It wont read/connect usb drives, IPods/IPhones/IPads, and Android phones. I have tried the PRAM and SMC resets and nothing has worked i even left my Macbook pro off for a whole day. ITS ONLY ONE PORT NOT WORKING, i took it to bestbuy because its closest to me but geek squad just did what i explained above and told me get a USB hub and NO! i want to fix this issue... Anyone has had this happen can you let me know if its because the USB port is no longer working or a software issue... Also i keep getting this notification telling me USB devices disabled draining to much power but i have nothing connected!!
ps- my MacBook Pro is getting very hot fast and it happens when im not even using it, i get home and it very hot could there be another hardware failure i dont leave applications open when i sleep it.

It sounds like you might have a hardware problem. Your best bet is to go to the Genius Bar. The evaluation is free, and they'll fix it if you're under Applecare. Back up your stuff first though.

New iMac as second display for MacBook Pro not working

I just bought the new thin 2012 27" iMac as a replacement to the last model I had.
I want to use the iMac as a second display for my 2012 MacBook Pro.
I have a Mini Display Port to Mini Display Port cable that used to work with my previous setup and at work with my external display.
However, this isn't working on the new iMac. When I try the Command + F2 suggestion I've seen in the forums here. Nothing happens.
Do I need a new cable now that these are "thunderbolt" connections?
Any help is greatly appreciated.
Thanks.
Demetre

You will most likely need a Thunderbolt cable as they are both Thunderbolt devices and not Mini DisplayPort.

Macbook Pro not working right after getting it back from Apple Store

I had to bring my last generation Macbook Pro into the Apple store to have a faulty optic drive and logic board replaced. I just got home and the date in the preferences was set to 2001 and it will not connect to my network, even though I am typing this on another Mac using the same connection. It does see it, it just shows a message with an exclamation mark in the Airport area saying no internet connection.
Any ideas of what I may need to do? Are both of these a sign that they may have messed something up? I did reboot it after getting it back.
Thanks.

Just bring it back. Have them check it out and demonstrate that it's working properly.

Left USB on MacBook Pro not working.

I've got a brand new MacBook pro unibody (not the one from WWDC though, I have the one with the removable battery (late 2008 I guess) and the left USB port which is closest to the firewire port doesn't work. The computer is only 3 weeks old and I can't remember if it ever worked, it may have worked with a USB mouse the first time I turned it on but I'm not sure. Since then I've tried it with my iPhone, iPod, external hard drive, 3 different digital cameras and the wired mouse again. It's not even a recognition issue because my iPhone/iPod doesn't even charge when connected! So I guess it's severely underpowered. The only sign of power I've gotten from it is when I plug in the mouse and the mouse's red light flashes twice then disappears.
I've tried resetting the SMC per Apple's directions here: http://support.apple.com/kb/HT1411
I tried both methods and still nothing. I've also run the hardware test but it found nothing (although I didn't run the long version).
Any suggestions would be most welcome! I'm thinking of taking back to the store tomorrow though (not an Apple Store, we don't have one here )

It sounds defective and you need to take it back to an Authorized Apple dealer or repair centre for them to fix it under Warranty.

Sound through HDMI on MacBook Pro not working

I've a MacBook Pro [Retina Display] (Mid 2012) with HDMI Output. I've tried to connect my Samsung PDP to it, and the Display is detected successfully. No problems in using the display in Mirror or Extended view. However there is no sound output on the Display. I've also tried to connect my Mac to Sony AV Receiver -- To my Samsung Display,the display is detected, but still no sound on AV Receiver.
I've than checked the sound preferences and it says that "The Selected device has no output controls". I've also tried to match the sound output Hz to input and tried all combinations, doesn't work at all. The Volume icon is greyed out as soon as I select the Output to Samsung. I'm now running out of thoughts.
My goal is to be able to Play sound on either the Sony AV receiver or Samsung PDP, either way will work for me.
Any help would be appreciated.
thanks
Rishi.

Some time ago I had this problem too. I had another Macbook with a broken main board, so I decided to wrack the connector. This showed clearly how the switch inside the connector works. It is a "normal on" switch, and it switches to off if a plug is plugged in. Then the software senses the connection to determine if this is a audio plug (metal) or a a optical connector (plastic). What happens, is that some dirt sticks on the switch, so the computer "thinks" it has a connector plugged in. Since it senses no connection, it switches to optical. The solution is clearly to clean the switch. That can be done, sometimes it might work from the outside, with the toothpick, compressed air, or whatever, but that didn't work for me. Best is to open up your mac, removing the keyboard, etc. Follow the instruction here: http://www.ifixit.com/Guide/Repair/MacBook-Core-Duo-PRAM-Battery/297/1, but not all the way! Don't remove the main board, or the cpu-cooler. Go so far that you can reach the metal strip on top of the connectors. This strip should be bend so that the connector is reachable. See first photo.The audio connector is inside a metal box. That box is for radio wave interference and for strength. So you can just wrack it open with pincers and a screw driver. Just watch out you don't drop any metal parts on the main board! When the box is removed, remove the plastic top. Now it is quite simple to clean the switch. See photo 2, the arrow is pointing to the switch. Don't be confused by the photo, you shouldn't remove the connector from the main board! On the left you see the wracked metal box. I used compressed air to clean the switch. When done (just connect the keyboard and start your mac to test), put back the plastic top, put some tape on it to keep it together and if you don't use brute force injecting a connector, you will be fine...
Hope this helps!

Sound on MacBook Pro - Not working

Is there any updates since February 2014 re: macbook pro not working with Smartboard?

My computer recognizes that it is attached but will not display what is on the desktop. I am currently running Snow Leopard on MacBook Pro and trying to project in onto a Smart Board 600 series. The MacBook Pro used to work with Smart Board; now, all of a sudden it does not work. And, sometimes it will project, but many times it simply will not. I am using a brand new adapter, and projection works with my Epson Powerlite 78 at home.
Smart Board refers me to Apple Support believing the conflict to be hardware. Incidentally, I downloaded Smartboard software to my MacBook Pro previously, but uninstalled it because it was causing crashes to my computer. But, users do not have to download SmartBoard software for projection.
Are there any possible solutions to my inquiry? Thank you for any considerations.

Hi, well basically our family got BT infinity about 2 weeks ago, and it worked with my macbook for about 3 days or so, but after that just suddenly stopped working. It says it's connected in airport and gives full connection, but chrome, spotify, skype, etc do not work. However the rest of the computers in the house which run on windows do work. For the last week or so I have been using a neighbour's open wireless (Netgear) which has been pretty consistent if a little slow. So basically, is there anything i can do? i've pretty extensively looked at all the forums regarding MBPs and routers, and it seems it may be a mac fault (meaning i may be in the wrong forum.) but any help would be appreciated. thanks.
Hi there,
It sounds to me like you're having troubles with the wireless channels on the Home Hub.
Here's what I'd suggest you do: Download istumbler on your Mac (or inssider 2 on your PC) and use this to check which wireless channel you're currently on and if need be, change to a less congested channel.
I hope this info helps.

Built-in camera macbook pro not working

Hi guys,
lately the built-in camera on my macbook pro hasn't been working properly: at first it works normally then after a while it stops (the green light stays on) and when I open photo booth or other programmes it says "camera not connected", how can I fix this?
Thanks

One of these will fix your problem:
(1) If restarting your Mac doesn't fix the problem,
(2) use Apple's http://support.apple.com/kb/HT2090.
(BTW - Apple has changed the built-in camera's name on newer Macs from "iSight" to "FaceTime" and then to "FaceTime HD." Regardless of the name of your built-in camera, the same info and troubleshooting applies.)
Be sure to test more than one Apple app in more than one user account. Do NOT use the "Guest" account for this test. If you do not have more than one user account for the testing, create a new one now. If you need help, here's how to do it in your Mac OS: http://support.apple.com/kb/PH11468 (A "Standard" account is all you need for testing.)
(3) If your cam still does not work properly, use Disk Utility to repair permissions. Then download and apply the latest Combo Update for your OS. Currently, the latest ML Combo is here: http://support.apple.com/kb/DL1571
Repair permissions again immediately following the system restart that completes the update.
(4) The only other action I know that you can do on your own is to use OS X Recovery to completely reinstall your Mac OS.
(5) If none of the above suggestions resolve your trouble, contact Apple or an Apple-Authorized Service Provider to have your Mac professionally serviced.

Projecting macbook pro not working

I hooked up my macbook pro to a project and the only thing displayed on the screen was my desktop image (no icons). Tried to change the display size on my macbook and projector - still not working.
Does anyone have any idea what is happening? What is the solution to my problem.
Thanks

This is because your computer in in extended desktop and not on mirror dipays. You will notice you can drag your windows the right and they will pop up on the projector. If you would like to mirror the display on your MacBook Pro and on your projector, go into system preferences and the to displays while connected to the projector. There should be a check box allowing you to mirror the displays.

MacBook pro not working properly - it was fine yesterday

oolder MacBook pro with Yosemite was working fine yesterday. today it is not. It takes ages t boot, once booted most apps don't work - I can't even open App Store or about this Mac. About the only thing that works is Firefox. Also doesn't recognise external hard/flash drives connected with sub but the hard drives show up in disk utility. I have repaired permissions through disk utility but no change. Has there been another ****** Yosemite update that could have caused this?
help please!!!

Try these in order testing your system after each to see if it's back to normal:
1. a. Resetting your Mac's PRAM and NVRAM
    b. Intel-based Macs: Resetting the System Management Controller (SMC)
2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the Utilities menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
4. Reinstall Yosemite: Reboot from the Recovery HD. Select Reinstall OS X from the Utilities menu, and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
            because it is three times faster than wireless.
5. Reinstall Yosemite from Scratch:
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.

            because it is three times faster than wireless.
