OS X :: Macbook Wireless Doesn't Work When External Display Is Plugged In?
Nov 11, 2008
I have a white plastic macbook which appears not to be able to connect to my wireless network. All the other PCs and a Mac Mini in the house connect fine, but the macbook does not.It has connected since i got it, both to the home network and a network in school, but today it promted me for the wireless password, connected a few times but did not give me a IP address, and now will not connect at all! The network appears in the list, i click on it, enter the wireless password, then it says connecting before connection failed.
The network setup is a Cisco router connected to the modem and then connected to the wireless too. There are no computers connected via cable to the network.

I'm using a Dynex Mini DisplayPort to DVI Adaptor to use a second display (an older display, I'll admit). After I have unplugged the adaptor, my MacBook still tries to read the second display, and switches back-and-forth between a blue screen & my desktop. It stabilizes once I plug the adaptor back in. What is causing this problem, and how do I fix it so I can use my primary display without having the adaptor constantly plugged in?

I have this gorgeous 22" ACD that I have plugged into my G5, where I use it quite often. But my intention for the G5 was to be a server, which it is. I often need some extra display space when I'm doing school work, or coding, so I was wondering if there is a way that I can use the display, while plugged in to the G5, as an external display for my MBP. Preferably something that I could stream over my local network.

My boss just gave me a MBP Core I7 2,66Ghz / 4GB Ram, model mid-2010 for the business. It is equipped with Nvidia GeForce GT330M as PCIe video card. If I plug an external monitor, I have, after some time between minutes or hours of work, a weird video problem, which obliged me to power off/on the MBP. Sometimes I even can see my mouse moving, but I can't do anything with it. If I do not use the external monitor I do not have problem. This type of problem appears around 3-4 times a day and make the MBP unusable, as I'm loosing the recent work each time the problem occurred.
Here is the extract of the console at the time of the crash :13/03/12 16:45:51,203com.apple.kextcache/: no supported helper partitions to update.13/03/12 16:47:29,000kernelNVDA(CopyEngine): Channel exception! exception type = 0x27 = CE0:
Unknown Error13/03/12 16:47:29, .....
The problem seems related to NVidia GPU. I've reinstalled everything from scratch without success.

I have to have my hard drive replaced on my Macbook Pro. I bought an external hard drive (Buffalo) plugged it in and nothing no pop ups for instructions. Does a new hard drive (external) need something done to it on first time use?

I am pretty displeased with Mac. I made the switch over last summer when Apple was having the big sale for college students. I bought a Macbook with 2.4 GHz Intel Core 2 Duo and 2 GB 667 MHz DDR2 SDRAM. It wasn't the cheapest white one, but it wasn't the expensive black one either. Reason one why I was displeased: the CD drive sounded like a motor boat when I tried burning CDs. After having that fixed, yet another problem arose that persists to this day: For some reason, my wireless doesn't work here at home. It works (almost) perfectly at school, but here at home, I have to be about 3 inches away from the freaking router for it to function properly. When I'm no more than 10 feet away, the signal begins to drop. Even when I have 3 bars of connection showing, my internet won't work at all. Coincidentally, when i click on the wireless button up at the top of the screen, it begins to function again (most of the time). It is really annoying. This is probably the last Mac I will ever buy. At home, I have a Linksys wireless router, Model WRT54GR.

For some reason, my macbook's wireless internet doesn't work at home. It takes hours to load a simple page if it doesn't time out. The wireless works everywhere but at my house which is frustrating when taking it to apple. Other apple products and computers connect to the home wireless perfectly but not this laptop. Apple suggested a reformat, but it did not help.

Macbook early 2008, OS X 10.5.8, 2.4 intel core 2 duo, 4G RAM
Wireless:Bell internet, 2wire router (Tried all the different security configerations with no luck) Works great hardwired.

We have an iMac G5 running 10.4.11 which developed some nasty colour banding down the screen and have now plugged in an external display. How can you turn off the iMac display so it only outputs through the external monitor?

I have some issue with my 2012 Macbook Pro Retina. The screen intermittently decides to just not work. Sometimes on startup i hear the start up noise but the screen doesn't turn on. I am able to remote into the computer when the screen doesn't work. I can't seem to find any rhyme or reason as to when it works and when it doesn't. I've reset the PRAM and SMC sometimes that will bring the screen back sometimes not. Â

I have this Seagate 1 TB ext HDD that I've been using with my old Windows, but unfortunately, when I connect it to my Macbook, I'm not able to make changes, nor can I edit or delete files or add new files to the HD. What should I do?Â

Have a brand new MBP 13" using Thunderbolt-DVI adapter with my old Dell 2405 LCD. Have an interesting scenario ... when the display goes to "sleep" there is still some type of signal coming out of the display port. The monitor will stay on and just blink "NO SIGNAL DETECTED ON INPUT 2". But the monitor actually still stays on.When I put the entire laptop to sleep them the monitor will properly power down to sleep mode.Â
I don't think its the monitor because I've used this monitor with a number of different machines and graphics cards, in every scenario when I had the display set to sleep it powered off just fine. Â

I used my Wireless Aluminum Keyboard over in Mac OS. I recently installed Vista 32-bit over bootcamp. After I boot Windows, I cannot use my Wireless keyboard. I paired using Windows help assistant or whatever but still cant use it. Do you guys have any same problems? What do you guys do? Is there any Apple Software update for this problem? I checked Apple support page but no luck!

I got my imac in November '09 and my caps lock works but the green led does not light always.
The only way i can fix it is remove the batteries
Or disconnect and reconnect the keyboard by clicking on the bluetooth icon
So if apple is not going to fix this bluetooth bug im going to see if apple will refund my money so i can get a wired one.
My friends keyboard does this also and im fed up with this bs...

I tried to set up a home share between mine and my girlfriend's MacBooks. It worked okay both ways, but then I disconnected my ethernet cable and the connection dropped.
I started fiddling around and discovered that home sharing only works as long as any one of the two computers is connected to the router with a cable. The other one can be connected wirelessly. But it won't work if both are wireless at the same time.

The external 19" LCD display does not work with the lid closed. However, it does work in full 1680x1050 when mirroring is turned off and the lid is open. When I turn mirroring on and the lid is open, the external display does not work at full 1680x1050, it shrinks the external view so the resolution is 1680x1050 but only displays 1280x800 worth of pixels.
Summary:
* lid closed, mirroring on, external display does not work (goes into "out of range" mode)
* lid closed, mirroring off, external display does not work (goes into "out of range" mode)
* lid open, mirroring on, external display will not do a full 1680x1050, instead will do 1280x800
* lid open, mirroring off, external display will do a full 1680x1050
A USB keyboard and mouse are attached. This exact setup worked flawlessly with a gen1 macbook pro out of the box.
How do I make the display work with the lid closed?

I'm thinking about updating my Macbook Pro C2D 15'', which is already 3 years old. I'm planning to get the 27'' Apple Cinema Display (finally!) when it come out later next month. I've decided that I'd go with 15'' Core i7 Macbook Pro, but couldn't make up my mind on the screen resolution; Standard 1440x900 or Hi-Res 1680x1050.The thing that really bugs me that the pixel-per-inch (PPI) of the MBP and ACD. The ACD 27'' has 108.79 PPI, with relatively close to 110.27 PPI on STD MBP, while the High-Res MBP will give me 128.65 PPI. This would mean that the text on the High-Res MBP screen would be a bit smaller.So, my question would be for the person who're using current ACD (24'' ?) with Hi-Res 15'' MBP or 17'' MBP (which has 113.xx PPI):1. Does the difference in text size seems noticeable when you switching from one screen to another?

I bought a MBA 13" last month and now I'm trying to connect an external monitor through a Mini Display Port-to-HDMI adapter and most of the times the display shows a message "No signal detected"...
I've tried all the possible combinations between the MAC and the Monitor but it would seem a random matter.

I went ahead and disassembled my wireless mighty mouse, unscrewed the scroll ball from the lid of the mouse and found a ton of lint and cr@p that has been living in here for quite some time. cleaned it all up, put it together, now all of the little rollers spin freely, great.
I go to put everything together, including the 2 ribbon cables, mouse snaps together, fire it up, mouse works fine, i can click, side buttons work, but the scroll does not work at all now. left to right use to be fine, it was just up and down. now nothing works.
any idea what could have gone wrong? did i forget something?

I just bought the 27in iMac to hook up to my Mac Pro till apple refreshes their ACD. I thought I would be able to use the Mini Displayport to DVI adaptor to connect it to my Mac Pro through DVI and it doesn't work. I know you can do it with mini displayport to mini displayport although, both my mini displayports are currently in use by by 24 ACD.

I was messing around with the ownership & permissions on my external HD and I think I may have switched it to no read & write.
Now when I plug the HD in, it shows up in Disk Utility and System Profiler but not in Finder. I've verified and repaired and neither of those things seem to help.
I'm not sure if what I did screwed it up or not.
I have some pretty important stuff on the HD. Do I have to reformat? Is there any terminal command or somthing that I can do to get into the HD?

i have a problem with my Snow Leopard installation. Since I've installed Snow Leopard, my external USB HD won't work anymore. It's a ICY BOX case with USB 2 and Firewire 400 interface. The mac is a mid 2009 mac mini (9400m).
P.S.: It doesn't show up in the disc utility
PP.S.: I tried two different hard drives in the enclosure, but all worked fine before Snow Leopard!

Looking to get a wireless external, is Time Capsule the only one that will work with a MBP? I would like my external to back up whatever I do on my computer whenever I am within range. I've read a lot of fail regarding Time Capsules

I have a late 2010 macbook air 11 inch. The battery condition is normal and about has 650 cycles. The light on my charger is green and my computer only stays on when the charger is plugged in. When I unplug it the computer just turns off and my battery says its not charging and that the power source is the adapter. Do I need a new one or is this fixable?
