Macbook Pro to Sanyo projector wireless ?

Greetings from Alaska.
Say I need some advice. We have a Sanyo projector mounted on the ceiling at our church. Currently I have a VGA and a S-video cables running down to meet our laptops. I notice that the S-video is much clearer on the screen (which I prefer to use).
The problem is that we have cables across the floor and people could trip on them. Is there a wireless solution out there. I did some searches and found a couple of items but their footnotes say not good resolution for computer screens.
Can somebody direct me to a system that is wireless and have maybe a DVI or S-video option?
Thanks,
Keith

iFelix thank you for taking time,
Most of the time it is static, but once in awhile I like to drop a quicktime into the keynote. Thanks for the link, that looks like what I'm looking for. One question though. When I hook up to the projector with VGA the picture is no way near the quality than when I hook up with the S-video.
Will I be sacrificing image quality with VGA?

I connect my macbook pro to an Epson wireless projector. The macbook can see the projector wirelessly and the image on the macbook is displayed on the projector. However on system ref., the arrangement tab does not show and thus cannot have multiple view.
I am trying to project Pro Presenter on the Epson projector such that I have the detail screen on the macbook and only the screen I want people to see on the projector display. This has not been possible because the arrangement tab on the Display section of the System Preference is not showing. If i tried to search for the arangement, it comes back with the message that there is not other source detected, hence the arrangement tab is not showing.
I have also tried to connect the Epson directly to the Macbook but it still the same result, so its not because it is a wireless connection. Can someone advise me jhow to go around this problem. I have used windows before and it is very easy to extend ptojection on windows, but this system seems to be frustrating to me.
Thanks,

I am trying to connect a Macbook Pro to a projector for a Powerpoint presentation. When I use a VGA cable, the color of the projected images are not good. When I use a USB cable, the projected image includes the presenter notes on my computer screen?

To move an iPhoto Library to a new machine:
Link the two Macs together: there are several ways to do this: Wireless Network,Firewire Target Disk Mode, Ethernet, or even just copy the Library to an external HD and then on to the new machine...
But however you do choose to link the two machines...
Simply copy the iPhoto Library from the Pictures Folder on the old Machine to the Pictures Folder on the new Machine.
Then hold down the option (or alt) key key and launch iPhoto. From the resulting menu select 'Choose Library'
and select the Library that you moved. That's it.
This moves photos, events, albums, books, keywords, slideshows and everything else.
Your first option didn't work because you imported one Library to another. Every version and thumbnail is imported like a distinct photo, you lose all your Albums, Keywords etc., the link between Original and Previews is destroyed, the non-destructive editing feature is ruined and so on. In summary: it's mess.
Your second option didn't work because you simply referenced her library on the old machine.

MacBook Pro to a projector

MacBook Pro to a projector which works with an image of the desktop but when I want to play a movie or show photos the projector shows a blank screen. Any one help? Connected via Lightning / HMDI lead.

&otIt really depends on the projector. I do this all the time too but your mileage varies. The most consistent way to get it to work is to "mirror" the displays (function-F7). This seems to work for me about 80-90% of the time. When in normal mode (expanded - mirroring off) it works about 20% of the time.
you can also trying setup a very "dumbed down; resolution. 640x480 or 800x600 seems to work better on most older projectors. the display looks a little crappy but it is what it is.
The MBP has had projector issues from the start. I hope Apple addresses it some day.
I've compared the MBP side-by-side with my older Powerbook and a Dell laptop. Both of these machines will work flawlessly with most projectors but alas not the MBP.
hope this helps.

I am trying to hook my macbook pro to a projector, which has a VGA cable. I bought a VGA to HDMI adapter, but whenever I hook it up, the screen on my macbook just goes black and I can't make it do anything else or even show up on the projector.

My laptop is still on; it just has a black screen that I can't get rid of without shutting down the computer by holding the power button.

Hey there lynmrigg,
It sounds like have an HDMI to VGA adapter connecting your MacBook Pro and your projector but the screen on your computer goes black and no image appears on the projector. I would use the troubleshooting in the following article to help resolve or isolate the issue here, named:
Apple computers: Troubleshooting issues with video on internal or external displays
Try unplugging the video adapter or cable and then plug it back in.
If more than one video adapter is in use (or "daisy-chained"), troubleshoot by using only one adapter.
Example: A mini DisplayPort to DVI adapter connected to a DVI to HDMI adapter is an unsupported configuration because there is a series of adapters in use.
If available, try using a different display and or adapter (or use a different connector by using DVI instead of VGA, for instance).
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.
Thank you for using Apple Support Communities.
Take care,
Sterling

17" Macbook Pro + PPT + Classroom Projector Trouble

17" Macbook Pro + PPT + VGA Projector Trouble
what makes the mini dv (adapter to VGA) out to classroom projector become non-functional for PPT Presentation view. It worked fine up until I installed Maverick.
As soon as I try to start the slide show, it goes into "extend desktop" mode (not duplicate displayes) and will not show the slide show on the screen. I have tried different resolutions settings but it does not change anything.
Thank You!

Hi Keith Davison,
Thanks for the question. Your MacBook Pro definitely supports video signals via Mini DisplayPort to HDMI adapters (see About Mini DisplayPort to HDMI adapters). If you are experiencing issues with this connection, you can use the following resource to troubleshoot:

Connecting a macbook pro to a verizon wireless network

how do i connect a macbook pro to a verizon wireless network? Wi-Fi connection automatically assigns an IP address and indicates that the Mac won't be able to connect to the internet. Two other MacBook Pros connect to the network without any problems. These Macs travel from home to school and back again and automatically reconnect when they are brought into the house.

I have read a few corporate IT policies and they are all PC-centric.
Unless your mac runs any windows tools such as Bootcamp Wine, Crossover, or a VM in parallels or VMware then your mac has no virus implications.
A few years ago word documents could be infected with macro viruses and although did not affect a mac a mac could pass them on. Up to date versions of Microsoft Word documents are not vulnerable to this flaw.
You could install ClamAV its a free anti virus app for the mac that would keep your IT dept happy.
Maybe I can find out what the WEP key is with a utility of some kind.
If you had a compatible usb wifi dongle and kismac you could crack their WEP key but this would be probably illegal in your country so I dont condone this activity but if you got written permission from your employer to give them a free penetration test, something that normally involves hiring a security company this would save them money and highlight the insecurity on their network.
Or use an Ethernet connection.

Hi,
Apple's AirPrint only support specific models while using wired or wireless network connection.
Plugging a printer into a USB port of Apple base is not supported for AirPrint:
AirPrint printers connected to the USB port of the Apple AirPort Base Station or Time Capsules are not supported with AirPrint.
As well you must use AirPrint enabled printers for a such, none of your printers are AirPrint enabled:

There are 3rd party solutions which allow sharing a printer connected to your Mac as AirPrint, Printopia as example provide a such:

Brand new macbook pro cannot connect to wireless networks

The first time I called apple tech, they thought it was a problem with my internet provider. I've called 4 times now, and I'm still getting the runaround.
I have an old (2001) G4 sitting right next to my macbook pro which can see numerous wireless networks and connect to them all. A strong connection at that. However, my brand new (refurbished) Macbook Pro Intel etc,.... supposedly best computer ever made, . . . . can see the same wireless networks but has never been able to connect. As a student, I saved for a year to buy this notebook so I could work at cafe's & study with my friends. My friends with PC's can all connect to these wireless networks. My friends with older, less expensive notebooks can connect no problem. I have never been able to connect. Bought this peice of junk 2 1/2 months ago - only because I didn't want to be stuck at home anymore with my desktop. Stupid me to trust apple.
I wish I could get my $ back, but I'm now being told that it's 30 days too late. Before they told me it was a minor thing and some software update could fix it. I did as told. downloaded and installed their 10.4.8 thingy - deleted all the keychain stuff - nothing. same peice of junk.
Now they are telling me to go back to the genius bar where folks are just rude to me and tell me they can't help me becuase I bought a "refurbished" model that didn't even save me $25. What do you know.
Anyone having problems like this? Anyone out there who can help me?

Okay,
I apologie for calling it a peice of junk. I know you all probably worship this machine. I'm just really frustrated. I noticed that this is a very common problem - though most of the posts identical to mine have dissapeared from apple.com - this well known defect is all over other discussion boards and websites like macdefect, etc,....
So, can any of you tech gods help me with this very well known, common problem that I haven't been able to fix with 10.4.8 upgrade?
Thanks for your time and assistance,

MacBook Pro Cannot Connect to Wireless Router

I have a brand new MBP and it won't connect to any non-apple wireless routers
- my computer is 2 days old (it's awesome and I love it accept that I can't get wireless connection at home)
- wireless router: westell versalink model 327 W
- PROBLEM: my mbp will detect the network just fine, but won't connect to it...just times out, it will connect to a neighbors linksys, but cannot load any internet pages, so still not helpful. When I try to connect to the wirelesss router using the network utility it asks for a WEP password, which it never did before because it's an open wireless router. (I know you should always password protect, but it's not my router...I'm just in the same house)
- I had a powerbook G4 and ibooks that have all connected fine to the same wireless network. My dad has an HP laptop that also connects fine
- it only connects to the apple brand airport wireless routers
- it will connect to the wireless router if I plug in the ethernet cord
- I have tried checking the connections, allowing all connections, repairing my disk permissions (even though my computer is only 2 days out of the box), resetting the router, opening the router so no password is needed...NOTHING WORKS!
- I also tried another wireless router (netgear): doesn't work
I've been reading around in some forums and this seems to be an apple and maybe more specifically a macbook pro issue (just by process of elimination). One forum said that it was because of an airport update that basically "breaks" mbp's airport and makes it not accept any non airport wireless connections, apple supposedly is working on a fix but who knows
I'm feeling disappointed and very upset that this is even a problem, especially with how many people I read are dealing with the same issue wit still no solution. My mbp was far from cheap and this just shouldn't be an issue. I'm planning on contacting apple and getting to bottom of this or at least some kind of answer.

- it will connect to the wireless router if I plug in the ethernet cord
this is because there is an actual physical connection between the router and the machine, so the router allows the connection automatically. i believe ALL wireless routers have a "Wireless Access List" in their config. the owner of the wireless router must add any machine or device seeking to gain access to the wireless router. consult your routers documentation on how to access the router from a web page and add your machine. this is usually done by adding the machine's mac address to the wireless access list. i added my 15"mbp and iphone to my netgear wireless router in about ten minutes and have no problem connecting every time.
also, when making any changes in Network Preferences, be sure to "Apply" after any change or adding any wep key. let me know if you have any questions.
