Power troubles with MacBook Pro
My MacBook Pro has stopped charging. I've changed power supplies, but it's not working. Can anyone help?
Your post suggests that you have a new power adapter. If you purchased it from Apple, then it is warranted and should be replaced, assuming it is in the warranty period.
If you have access to another power adapter, try that. Have you checked the contacts of the MBP and the power adapter? Have you checked the battery condition?
Ciao.

Trouble with MacBook Pro finding AirPort networks
I recently bought a new (refurbished) MacBook Pro (15", 1.83GHz), to replace my old iBook, which was one of the early white models, circa 2001.
Everything about my new computer is wonderful, of course, except that every time I boot up, wake from sleep, or turn on the AirPort, it takes up to a full minute for the AirPort to find any open networks. This happens at school (where there are AirPort base stations all over the place), at home (where we have a Belkin router, and several neighbors have others), and at my parents' house (where they have a linksys router). It doesn't seem to matter whether the networks use encryption or not, nor how close or far I am from the nearest router. If I know the name of a nearby open network and type it in, I can get it, usually. On my old iBook, I had a little trouble with some of the networks at school sometimes, but never with this kind of delay across the board, and certainly never at home nor at my parents'.
Also, at home, when the the AirPort finally does find the available networks, it NEVER chooses my router first, even though it's the only one in the neighborhood that I listed under "Preferred Networks."
I've read some similar posts, dealing with problems with accessing encrypted networks, but nothing seemed to address my particular issue. It might be a defect with the AirPort or firmware, but I wanted to check, first.
(Oh, and I'm not a complete newbie, but tech-speak often goes over my head. Please keep it simple.)
Thanks!This is how I fixed the problem on my MBP.
Go to Macintosh HD > Library > Preferences
Delete the folder SystemConfiguration
Go to System Prefrences > Network > Show+Network Port Configuration. Check Airport and Built-in Ethernet and make sure Airport is on the top of the list.
Reconfigure your wep passwords and it should work. Worked for me. Also, you will have to redo your power settings.

Macbook power adapater with Macbook Pro...??
Hi guys,
So I just got home for the holidays and realized I forgot my power adapter for my *Macbook Pro*. However, my dad has a Macbook. I know they're not the exact same adapter, but is it a problem if I use his adapter with my laptop?
Thanks!If the battery is fully charged it will power it (or if it is not running it will charge it a bit slower than normal) e.g. the 60W will be enough to do one or the other.
Search here for the other 1000 times this has been asked.
Lower wattage = charge or run not both, higher wattage = both and in the case of a MacBook with a Pro adapter, it won't catch on fire (which is a common theme as people confuse power adapters with light bulbs in terms of power consumption).
Searching google will come up with 10,000 more confirmations of this. -
Trouble with MacBook Pro To TV connection?
Having purchased a DVI to HDMI adapter and connected my MacBook Pro to my TV using this adapter and an expensive HDMI cable, I still cannot get a signal to my TV.
I have selected the correct input channel using my TV remote, but still get a 'No Signal' message from my TV. I have tried running through the the other inputs, just to make sure, but still no signal.
I have checked all of my cable connections and they are all okay.
Does anyone know what may be my problem?
I could really use some help!Howdy needymacuser,
First I'd recommend trying another display and/or cable/adapter (if possible) to verify that there's no issue with either of those. If those check out or aren't an option, I'd recommend resetting your MacBook Pro's PRAM and SMC.
Reset the system
You can reset the Mac's parameter RAM and SMC.
Reset the resolution
Start by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
Start up in Safe Mode.
From the Apple () menu, choose System Preferences.
Choose Displays from the View menu to open the preferences pane.
Select any resolution and refresh rate that your display supports.
Restart your computer.

MacBook power cord with MacBook Pro?
Hi,
I have a MacBook at home, and a MacBook Pro provided by my company for work. Can I use the power cord from my MacBook to charge the Pro??
My understanding is that it will still work, but it will just charge the MBP battery slower. Is that correct?
Thanks,
SSCan I use the power cord from my MacBook to charge the Pro??
Charge as in only charge the MBP (i.e., closed lid). There won't be enough juice for using and charging consistently at the same time, depending on what you would be doing, which may actually lead to the battery discharging while connected to the smaller power brick. -
Having trouble with macbook pro dock at the bottom of the screen
I have a 13'' macbook pro, and i now have 2 different docks at the bottom of my screen. One is functional and the other one is not. How to i get rid of one of the docks?
Please post the age of your MBP, IE what year is was made, IE what year Model is it. and also as above a image/picture of the screen (a Screen Shot may not do it if the second Dock is some type of Ghost entry).
Other then that you have some type of software corruption or hardware failure going on. There should never be a second Dock at the bottom of the screen. So there is No easy fix for this problem. It may be hardware and if so that hardware would need to be replaced. Or is could be software corruption and in that case a Wipe of the drive and reinstall may be needed. -
When I first attempt to power on my MacBook Pro, the LED blinks but the MBP doesnt turn on. However when I try a second time the LED blinks but my Mac turns on. Is this a problem with the hardware and can it be fixed?
Also, I apparently have to replace my battery. Could the problem have any relevance to a dead battery?Have you held the power button down for 10+ seconds? That should turn it off.

I have a Time Capsule version 7.7.3 (model A1470) which has worked fine for almost 2 years with all devices, Apple and otherwise. As of beginning of this month, March 2015 - no longer works with a new IPAD mini 3 and 6-month old iPhone 6 (both updated as of last night) BUT still works fine with MacBook Pro (Mavericks 10.9.5) and Epson printer XP-600.
On both IOS devices Airport Utility shows the Time Capsule and shows green light connection to internet, but never does the connection. The little status circle just keeps going round and never shows the Wifi rainbow symbol. both devices work fine on other Wifi's. Airport Utility on iPhone actually connects enough to check on Airport base station's firmware 7.7.3 and says it is up to date! but sadly stays on LTE.
Have tried resetting, replugging etc...
Also, tried checking on updates. Nothing shows in Airport Utility. When I try to go to see past updates ~/Library/Application Support/Apple/AirPort/Firmware to see if updated, there is no Airport in the Apple folder?
A mystery...Reset the TC to factory and redo the setup. see details below.
Here is the typical list of things you should try.. and if this doesn't help post again.
Factory reset universal
Power off the TC.. ie pull the power cord or power off at the wall.. wait 10sec.. hold in the reset button.. be gentle.. power on again still holding in reset.. and keep holding it in for another 10sec. You may need some help as it is hard to both hold in reset and apply power. It will show success by rapidly blinking the front led. Release the reset.. and wait a couple of min for the TC to reset and come back with factory settings. If the front LED doesn’t blink rapidly you missed it and simply try again. The reset is fairly fragile in these.. press it so you feel it just click and no more.. I have seen people bend the lever or even break it. I use a toothpick as tool.
N.B. None of your files on the hard disk of the TC are deleted.. this simply clears out the router settings of the TC.
Setup the TC again.
ie Start from a factory reset. No files are lost on the hard disk doing this.
Then redo the setup from the computer or perhaps it is better using iOS on the phone or ipad currently having issues.
1. Use very short names.. NOT APPLE RECOMMENDED names. No spaces and pure alphanumerics.
eg TCgen5 and TCwifi for basestation and wireless respectively.
Even better if the issue is more wireless use TC24ghz and TC5ghz with fixed channels as this also seems to help stop the nonsense. But this can be tried in the second round. For iOS the fixed channels particularly for 2.4ghz has helped.
2. Use all passwords that also comply but can be a bit longer. ie 8-20 characters mixed case and numbers.. no non-alphanumerics.
3. Ensure the TC always takes the same IP address.. you will need to do this on the main router using dhcp reservation.. or a bit more complex setup using static IP in the TC. But this is important.. having IP drift all over the place makes for poor networking. If the TC is main router it will not be an issue. This is a problem for a TC in bridge mode.
If this is of no help.. what modem do you have? What function other than modem does it have.. ie none or router??
How is the TC connected into the network? What function does it have? Router or bridge for example.
Post a few screenshots of the setup. -
I am having trouble connecting MacBook Pro (10.6.7) to Novell server. I get incorrect username and password message. I can connect worksations running 10.5 without any problem. Any possible solution? Thanks, Ned
Having the exact same problem with connecting ML and Snow Leopard machines to a Windows 8.1 machine. Oddly enough, connecting and copying to/from works perfectly from a Mavericks machine, despite the problems reported about Mavericks regarding the exact opposite. An old thread, but did you find a solution?

Does 'Network Connect' work with MacBook Pro?
My safari unexpectedly quits when attempting to log into my company's VPN.
- I log into our VPN website and the connection begins to initialize
- with my MacBook, Safari (2.0.3) unexpectedly quits
- with my PowerBook, 'Network Connect' automatically starts and the VPN connection completes without any problem
Does 'Network Connect' work with MacBook Pro? Any ideas?Resolved. MacBook Pro was having trouble dowloading the 'Network Connect' application when I logged into my VPN client for the first time. I copied it from my PowerBook G4 over to the appropriate folder and it now works perfectly.

What's the power Adapter for Macbook pro 13inch Mid 2012
What's the power Adapter for Macbook pro 13inch Mid 2012 with core i-7, 2.9ghz, 8Gb ram?
AFAIK it should be a 60wat Megasafe power adapter.
But mine shipped with a 45Watt Megasafe. I got it as a Gift from my friend.
Thanks in Advance.mmaumio wrote:

This should be my Adapter right?
Yes.
There is a drawback in addition to taking a longer time to charge up your MBP. In unusual instances when using your MBP with power adapter attached, and running a very heavy load on the CPU/GPU, the MBP will require additional electrical resources in addition to what the power adapter can provide. It will then draw upon the battery. What this means is that using a 45 watt adapter, these conditions are more likely to occur.
Using a 45 watt adapter should not harm your MBP as such.

What product can I buy that will supply portable power to my MacBook Pro, iPhone and iPad when I am flying?
I recently was on an extended trip and the port for charging at my seat was not working.Unfortuntly you can't.
The Apple Airline adapter is only meant to keep a fully charged battery from draining, however with newer computers requiring more power, they tend to drain the battery AND the power at the same time, thus require more power hook up without the computer running to charge the battery.
Since your iPhone and iPad charge off USB, that's going to drain the MacBook Pro battery as well.
To generate enough power to charge all three will require a portable generator which of course can't be used on a plane.
The best you can do is have all three charged up before you board the plane, and use each for as long as you can. -
Is the latest 280.26 nvidia driver compatible with MacBook Pro 6,2 model?
Is the latest nvidia driver (280.26) compatible with MacBook Pro 6,2 model)? Boot Camp 4.0 comes with the 262.41 nvidia driver, but I'd like to upgrade to the latest 280.26. The official 280.26 driver page on the nvidia site says that GeForce GT 330M is compatible, but in the footnote is written this thing:
Notebooks supporting Hybrid Power technology with Intel chipsets are not supported by this release
Do you think this is the case of MacBook Pro 6,2 model? Can I upgrade the driver without any problem?
P.S.
I've the nvidia geforce gt 330m 256 MB.Mac OS X 10.8.2.

Cinema Display (clear) with DVI/ADC box doesn't work with MacBook Pro
Cinema Display (clear) with DVI/ADC box doesn't work with MacBook Pro when plugged in with a dvi to mini dvi cable. Any ideas what to do to make it work? I lugged the 23" 2500 miles into the wilderness and I need help
Okay, here's an update: the DVI to ADC adapter does work with the Apple displays that I have tried, but it won't work with the Formac. I have tried multiple time to contact them, but to no avail... they don't even respond to threats of posting my opinion of them, which is this:
DON'T BUY ANYTHING FROM FORMAC! They make quality products, but their customer service is a big time joke! They won't take care of you.
