Connecting to a projector knocks out trackpad

Whenever my wife connects her MacBook Air to a projector, it knocks out the use of her trackpad. The mouse pointer simply jumps around when you try to move it. Connecting an external mouse brings full control back.
Is there any solution out there for this?

This has been reported before. I seem to recall it's a hardware incompatibility issue, possibly related to poor grounding in the connected external device. I don't think there is an easy fix unless you can correct the issue in the projector.

How To Stop After Effects From Knocking Out My Internet Connection As It Is Downloading?

Greetings,
Yesterday, January 20, 2015, I purchased an annual subscription to After Effects. And, after numerous attempts at downloading the software with the same abysmal results, I am now going to the forums for a possible remedy. Everything goes well in beginning my download, including getting my McAfee Anti-virus program to accept Adobe Creative Cloud, however after a few minutes, the download process knocks out my Internet connection, forcing me to re-boot. I do receive two back-to-back error messages; none of which are listed by Adobe set of error messages in their FAQ section.
The first one reads: "Core: Creative Cloud - Application Error. The instruction at 0x100014a0 referenced memory at 0x100014a0. The memory could not be written." The second error message is likened to the first, only with a different number...
"94% Complete: explorer.exe - Application Error. The instruction at 0x80001610 referenced memory at 0x80001610. The memory could not be written."
Finally, do you know if I can bypass all of this trouble by having Adobe After Effects disks shipped to me? Any assistance will be greatly appreciated.
Joy in the Lord,

Greetings,
And thank you both, Mylenium & Dave. After I compose this note, I am going to mark your answers as correct. I just wanted to write this qualifier, first. I tried to do as both of you suggested, however, I could not figure out how to disable McAfee Anti-Virus. I did manage to turn off McAfee Firewall. And when that was done, I tried to download After Effects. However, that trick did not work the first couple of times I tried it. A few re-boots later, After Effects (as well as some unknown program I did not expect called Media Encoder) finally downloaded on my computer.
After I began this thread, I recalled that, oftentimes, when I view YouTube videos online, the same thing happens - my Internet connection gets disrupted. Then I remembered that the trouble began when my computer crashed and I tried to re-install Windows 8.1 Pro. So, maybe that is the real culprit - my system crash, that is. A little while ago, I tested viewing YouTube videos to no avail. So, I am suspecting that your solution to turn off my anti-virus (in my case, my firewall) did the trick, and I thank you two, Mylenium & Dave, mightily.
May you have many blessings.

Monitor command knocks out internet connection

cisco 2651XM router
IOS: c2600-adventerprisek9-mz.124-15.T9.bin
fitted with NM-16-ESW switch module on to 172.1.16.xx
I have a mail-and-web server plugged into fa1/14 on the switch module in this router, along with a PC plugged into fa1/7, and the router is connected to the internet.
I'm using monitor commands to feed traffic data on f1/4 to fa1/7 thus:
(config)#monitor session 1 source interface Fa1/14
(config)#monitor session 1 destination interface Fa1/7
The reason for this is I'm using wireshark on the PC (in f1/7) to watch traffic on the mail/web server (on f1/14) and it works great except that the monitor destination command knocks out my internet access on the PC. Without the monitor commands internet access is fine. I tried the whole thing again on a different PC and that lost the internet too so the problem is in the router.
Is there a solution to this that will give me both the traffic feed and internet access? Thanks for any help.

Hello Tony,
unfortunately it looks like that your only option is to add a NIC to the PC
http://www.cisco.com/en/US/docs/ios/12_3t/12_3t4/feature/guide/gt1636nm.html#wp1053663
>> . You cannot configure a SPAN destination interface to receive ingress traffic. The interface does not forward any traffic except that required for the SPAN session.
Hope to help

My MacBook Pro with Retina display displays power point and not other windows when connected to a projector

My MacBook Pro with Retina display displays power point and not other windows when connected to a projector. Can anyone help out please?

You should also ask this in the MacBook Pro forum. This is the forum for the white and black plastic MacBooks that were discontinued in 2010. You should also post this question there to increase your chances of getting an answer.

I lecture for a living. My old G4 connected to LCD projector worked great. My new MacBookPro connected to LCD projector - the displayed images look as if I used "pastel colors" instead of bright colors. Help !

I lecture for a living. My old G4 connected to LCD projector worked great; image displayed on computer monitor is same as that projected by LCD. However my new MacBookPro connected to the LCD projector displays washed out images, as if I designed my Keynote lecture using pastel colors. Also my black & white x-ray images are blue & white. Help !

Thank you for your quick response to my question. The Apple Genius Bar tried adjusting the color settings in my MacBookPro, as stated in the document you attached. It did not help ... my Keynote lectures are still pastel, and my x-rays are blue & white. I should have stated this in my original query for help.
Again, many thanks for responding.
Did the Apple Genius explain to you why it did not work or even if it's possible?

Connect ipad to projector or PC

I teach in a classroom that has a PC connected to an Epson projector. I would like to use an ipad app (such as explain everything) to record audio/video of me working problems in class. At the same time I'd like the ipad screen to be projected by the Epson projector. I'm not sure if the projector has wireless capabilities, but it may. If so, is there a way to connect the ipad to the projector wirelessly? The other possible option is to connect the ipad to the PC wirelessly (I don't want my ipad tethered to anything), then the PC connects to the projector. Can anyone give me pointers on whether any of this is possible and if so, what is the best approach?

The only way, I believe, to connect an iPad wirelessly to a projector is by connecting an AppleTV to the projector - and I don't think most projectors have the correct input for it.
You can use a number of apps to control the computer through the ipad. There are a few apps that are designed to replicate an interactive whiteboard. One I'm trying is Splashtop Whiteboard - it allows you to use the iPad to annotate over an image on the computer and then project it, or to even use their own flipboard as a background to writing. This would, in theory, allow you to do your work directly on the iPad and send it to the projector through the computer. I say in theory because we are having problems with it, both the app itself and then running it through a whiteboard projector - I've been working with a tech support rep at Splashtop to see if we can resolve it before I can decide whether to recommend to other teachers, as right now I can't - but other people apparently are using it succesfully.
Another app that has similar promise (and higher reviews!) is Doceri Remote. The app is free, but the desktop software is not - $50 (the splashtop app is $20), plus they strongly recommend their proprietary stylus. Because they sell the computer software and not the app, however, you can do a trial - 5 days, I believe, we're going to give it a try after winter break. You can also, I believe, record your presentation using Doceri.
For recording ... while Doceri promises it, it might be easier to use a Screencast software (such as Jing) to record it on the computer - if you're using one of these apps to control the computer and project out, anything on the computer will be recorded by Jing and then you can share it later.

Why does my Mac Book go to a presenters mode when I connect to a projector?

Why does my Mac go into a presenters mode when connected to a projector or system?

But does it then come fully awake? My MB Pro comes on with out of focus screen as if in a fog but once it comes awake it clears up, there is a progress bar at the bottom showing the progress from sleep

Connecting unknown, unfamiliar projectors and TVs to MBP

Connecting unknown, unfamiliar projectors and TVs to MBP
Hi:
I am going on a business trip to Europe and will be connecting my MBP to unknown projectors and/or TVs.
Which cables should I take for the "just in case" scenario?
Thanks for your help.
Tek
PS—Can one edit one's posts around here?

This forum is for the Mac Pro, the desktop, no the MacBook Pro, the laptop. You might have better luck in that forum.
That being said, I would make sure you have a DVI cable, a VGA cable, and the DVI->VGA adaptor that came with the MBP. I personally would also bring/buy the DVI->Video adaptor (P/N: M9267G/A) along with a s-video cable and composite video cable (standard RCA cable, usually yellow) just in case. Also, I would test all your cables before you go to make sure they work. Nothing is worse than getting there and then realizing that you went through all the trouble to lug around a cable and then find out it is faulty.
Generally any new projector will allow either a DVI or VGA connector, with DVI being the preferred choice. But there are still some old projectors out there that only accept s-video or composite or maybe their other inputs don't quite work right. Also, you might be forced to use a TV if you get there and find that the projector is broken or something and those other connections will come in very handy.
Probably a bit overkill. But I like to be prepared, especially if I'm going all the way to Europe to give a presentation. The extra cost/time is negligable compared to not having what you need.

MacBook Pro and Leopard knock out my wireless network

I am new to Mac, just having purchased the MacBook Pro with Leopard 10.5.1. installed. I have a Netgear WPN824 router that works perfectly with windows based computers. I use WEP 64 bit security. The MacBook connected with no problem and surfs the web fine until I try to download certain files on the MacBook (such as the HP drivers for my all in one printer) or try certain video feeds online , such as a cnn video. The download not only stops midstream but actually knocks out my entire network causing me to have to unplug my cable modem and router and restart everything. This is a real problem. Does anyone have a clue why this is happening? I can download the same files on a Windows laptop with no problem. Help.

Hmm. It might not be the MBP. Are you using Safari? I've noticed that Safari at times is incompatible with many websites. Try downloading Firefox and try the same downloads.

My new iPad keeps knocking out the whole household's WIFI

I got a new iPad 16GB 4th gen today. I have got as far as connecting to my WIFI to set it up and have typed in my password for the WIFI. Now I cannot get any further because the iPad keeps knocking out the WIFI connection for the whole household. I literally cannot set up my iPad because it keeps killing my connection the minute it is switched on. Can anyone help?

Sounds like there is a bug in the firmware of your router.
Check for a firmware update on the support web page of your router's manufacturer.

IPad knocks out wifi for whole household

Hey everyone. Just bought an iPad 2 wifi and every time I use it for more than fifteen minutes it not only loses connection, but knocks out the connection completely. Every other device in the house remains connected to the network, including the iPad, but the internet connection is completely lost and I have to reboot the router. Is anyone else experiencing anything like this?

Knocked out wireless compatibility with network printers?

I'm having this same issue with my 2008 MacBook running 10.7.5. Reading some other forums, it seems as if Lion knocked out wireless compatibility with network printers...
I have rebooted my machine, uninstalled and reinstalled all my drivers and continue to have this issue while not having the same issue with my Dell (work issued) laptop. First time a PC has ever performed better than my Mac.
<Re-Titled By Host>

I still have questions about how to connect the Brother printer through ethernet. When connected does the airport utility have some area where you can identify the printer as a network printer as opposed to USB?
The AirPort Utility would only come into play if the printer was attached to the TC's USB port. Printers, attached by Ethernet, would have to "network-ready." Controlling these types of printers would be through the printer driver that you would access through the operating system interface.
In my HP example, the HP printer driver does provide access to a number of features particular to this printer model. Most manufacturers include an installation CD that provide useful utilities ... albeit most are written for Windows. I would suggest checking out the Brother support site to see if they have Mac-specific drivers or utilities.

Connect MacBook to projector

Need to connect to a projector to do a powerpoint presentation. I bought a Apple Mini DVI to VGA Adapter and it connects fine to the computer, but the other end is a female end with 15 holes and the projector has different female connections. I assume I need a male to male with 15 pins to make this work. ???

Thank you.
