Question about using a Projector with MacBook Pro

Sorry if this is the wrong post location, but I figured people here would be the most knowledgeable about the topic.
I'm looking into getting a portable projector for under $450 that will work with my 2009 MacBook Pro for: a) watching instructional videos and b) doing some web surfing and a little programing. I can't get a monitor because I need portability and a picture at least 30" due to some visions issues.
I've looked into a few including the Optoma PK301 (sold at apple) and the Samsung 410ME (higher lumens, but lower res). Most of them have a max resolution of 800x600 and I'm wondering how that will appear on a 30"-45" projection? Will websites wider than 800 pixels be cut off? Does that mean a video with a resolution of 960x540 will be cut off or look funny?
The PK301 has a Native WVGA (854 x 480), but "supports" WXGA (1280 x 800) through VGA adapter; HD (1080i) through HDMI. So how will that render on the wall?
I sincerely appreciate your time and help.

I bought the PK301 becasue it has great reviews. But not on the MAC products... If any mac techs are around... appreciate some help here. Thanks.

Hello chrispyw,
If your content is still being displayed incorrectly, I would check the resolution setting for the built in display with this article:
OS X Yosemite: Adjust your display’s resolution
If it keeps happening whenever you use AirPlay then I would use this section of the following article to reset the display system:
Apple computers: Troubleshooting issues with video on internal or external displays
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.

Use InputRemapper
This is one or only utility I know, there are I am sure one or two others.
And the weakest link in running Windows on Mac: lack of thermal/SMC fan control to manage air flow and heat!

Using European Outlets with Macbook Pro

Hello Im about to buy a Macbook Pro and am traveling to New Zealand for a semester abroad. I believe this country uses the same outlet system (and higher voltage) as most European countries. My question is: Is there an adapter sold by apple for converting between American and European outlets? Is any power converter safe to use with my Macbook? Thank you for any information!

Check out:
http://store.apple.com/1-800-MY-APPLE/WebObjects/AppleStore.woa/wa/RSLID?mco=6C0 4E115&nplm=M8794G/B
I believe there were some posts on this a while back. You might search for "power adapter" or something like that. There are also some user reviews from the Apple store concerning the product above.

Question about using Apple Mail with Verizon

Not sure if this is an Apple or Verizon question, but leaning toward the latter so here it is...
On my MacBook Pro, running OS 10.8.3, I have several accounts. Each has its own Verizon username e.g. [email protected], [email protected] etc. Everything had been working fine but last night I had an issue sending email from, say, the username1 account. I went to the username account to test it out and it worked fine - I sent an email to username1 in Mail and username1 had no problem receiving it. But username1 couldn't send email - it gave an error message about the outgoing server, asking me if I wanted to try another one.
Now the odd thing is that the outgoing server name was (and has always been) exactly the same for username1 and username. But when I selected outgoing.verizon.net:username1 instead of the usual one, it was able to send email. I'm not sure why that other server name was listed as an option, but glad that it was there.
So my question is why would two accounts on the same computer have to use two different Verizon outgoing mail servers in order to send email?
Thanks.
P.S. I should mention that, based on input from this forum, I ignored Verizon's "urgent" email from back in March about changing mail settings.

There's input, and then there's input.
By this time you should be using only the recommended settings across all your devices and platforms. As far as I can determine, all devices, operating systems, mail clients, etc., have been successfully configured using the new recommended settings. There are indeed individuals who are still finding issues, but the general consensus among experienced users seems to be that the issues reported are related to individual settings and devices, and do not stem from the server side.
BTW I don't at all mean to suggest that a particular user is anything less than capable. I'm just stating what I believe is the situation today.

Using digital projector with macbook

A basic question from an escaped PC user.
What keystroke is used to tell my macbook to send the display output to an external projector?
I need the equivalent of the F8 key I used on my work supplied PC laptop
I have purchased the link cable so the hardware side is OK .

As usual with a apple you don't need to do anything! I use mine for presentations and you just plug the projector in and hey presto.
You can adjust the screen setting in System prefs, Displays.
If you use iWork, Keynotes is great using this setup. You can run the display on the projector and get a real host of info. up on the MacBook display.

Trouble using external iSight with MacBook Pro (which has built in camera)

Hey Jim,
Have a question for you. I have a new MacBook Pro 17". I also have a 23" Cinema Display, and a left over Firewire external iSight camera (which I used to love).
Frequently I "dock" my MBP with my 23". I either use the dual-screen between the two, or I close the lid on the MBP, let it go to sleep, then wake it back up with a BT keyboard or mouse, letting it go to a single-screen mode on only the 23" Cinema Display.
So, I'm trying to use my external Firewire iSight with my MBP, and I'm getting mixed results -- the best of which is where I am getting some video with regular, occasional freezes with the picture being split (like a v-hold problem on an old TV). After a pause it goes back to smooth video.
I guess primarily, I'm wanting to know what the world of two iSights (FW and built-in) look like, and can they work together? I cannot for the life of me get this FW iSight to work consistently, but I know it works perfectly in another G5 tower (which has no built-in camera).
Any suggestions or guidance?

Hello Exivus
... two iSights (FW and built-in) ... can they work together?
You can have two iSights connected at one time, but, as explained in Apple's iSight "Your camera is in use by another application" message, iSight can be used by only one application at a time. (my emphasis)
Different apps select between multiple connected cameras in different ways. For instance, iChat > Preferences... > Video settings can select which camera to use with the iChat app, but iMovie 6 uses a drop-down menu as shown in this picture:
The suggestions in How to Troubleshoot iSight should help you determine whether one of your iSights is causing trouble. I suggest you test each one separately and without your external display or other peripherals to rule out possible conflicts.
After you are certain that your iSights are working individually, test them when both are connected. After your system successfully passes these tests, you can add your external devices back one-by-one to be sure one of them is not causing the problem.

Using EarPods Mic with MacBook Pro 17" (2012) - not working

hello,
FYI: computer is the early 2012 MacBook Pro - last of the 17" models. it has the 2 separate jacks... one for audio/mic IN and one for headphone OUT. not combined like in the smaller models.
FYI: using a brand new (early 2013) pair of EarPods that came with a new iPhone 5.
i love using the earpods plugged in to the headphone jack to listen to music whilst working. and i also use it to "listen" when doing video conferencing via Skype, iChat/Messages, & Hangout.
but when i'm in a noisier environment (cafe), it would be nice for the other people i'm talking to to hear be better than what the built-in mic can provide. people tell me they hear me great using the earpods when talking thru my iPhone in the same locations.
so, i thought, okay, i'll just get a Y-splitter/adapter... female input to 2 male outputs. recognizing that the earpods have 3 rings on the mini-jack (2 for stereo headphones & 1 for mic, i presume), i made sure the adapter male ends had at least 2 rings on them. found one at Radio Shack.
but it does not work! :-(
discovered audio output comes thru fine, but the computer doesn't recognize the mic input.
i've gone to System Preferences > Sound > Input...
and changed the selection from "Internal Microphone - Built-in" to "Line In - Audio line-in port" but the level meter just goes dead.
i've done some reading about the MBP only allowing "line level in" vs "mic level in" but i don't know what that means.
can this work? if not, why?
am i just missing some setting somewhere? if so, what?
do i need some different kind of adapter? if so, please point me to one.
THANKS!!!

Good that it was a simple solution. I've had some of the mice lose the BT association and you have to clear out the configs and re-pair the two.

Using external iSight with MacBook Pro crashes iChat

I use my Macbook Pro in clamshell mode with an external display. I bought an external iSight so that I could use iChat AV. I have the appropriate adapter to convert the Firewire 400 cable to Firewire 800 which is compatible with my '09 MBP 17" (2.8GHz).
Every time I connect the iSight, iChat will launch, and then will crash (SPWoD). I can not recover unless I disconnect the iSight, at which point iChat is able to fully launch.
I tired changing both iChat and Photobooth to 32-bit mode (hint from another thread), but that did not help.
As a test, I connected the iSight to an iMac with both FW400 and FW800 and the iSight works perfectly with either connection. iChat AV then allows me to then select which camera I want to use in its preferences.
Both my Macbook Pro and the iMac are on OS X 10.6.2. iChat crashes regardless of if I am using the MacBook Pro in clamshell mode or not.
TIA.

Thanks for that info, bryanus
Between this info and your latest response to Ralph, there are so many possibilities that I cannot yet identify the source of your problem. More troubleshooting is needed to identify the cause so we know what to fix.
Your used iSight may be causing the problem. Because it is easiest to troubleshoot, I suggest you test the external iSight next. The following will either eliminate your external iSight as the cause of your problem or let you know whether it will require professional service.
If the testing I suggest below shows that the problem is related to iChat ONLY, stop the testing I suggest and follow Ralph's expert suggestions for troubleshooting and correcting iChat.
Don't worry about the "clamshell mode" issues at this time. Until you get your external iSight working reliably with your MBP, keep the external display disconnected.
Additionally, to eliminate possible network problems as a contributor to your problem, when testing (internet) connected apps like iChat, use the same ethernet connection when you test both Macs. Even use the same ethernet cable (no wireless) connection to all Macs.
Also, to test problems with launching iChat, _disconnect both Macs from the network_ to see if iChat will launch properly with a connected external iSight but no internet or network connection.
You have already done some excellent testing, but you can use the additional suggestions from the following link (including other subject links on that page) to test the remaining user-correctable possibilities:
http://www.ralphjohns.co.uk/EZJim/EZJimpage4.html
Pay particular attention to *possible conflicts*, testing with more than one cable and/or adapter, and testing the external iSight on more than one Mac. If possible, it would be also good to use your same cable and FW Adapter to test your MBP's function with a different and known-good external iSight. If you have no other access to a working external iSight, your local Apple-Authorized Service Provider may be have one that he can use to check your MBP connection.
If your external iSight can connect reliably to other Macs, or if a different, known-working, external iSight also gives trouble on your MBP, the problem must be either in your MBP's physical Firewire connection port or in the software on your MBP.
Unless you find a fix while trying the above, we can offer suggestions for the particular problem(s) you identify based on your troubleshooting, so give as much detail as you can about your findings when you post back.

Using Modem MA034Z with MacBook Pro with Intel Processor

I have just bought the MacBook Pro to replace my old PowerBook G4 but find I no longer have an internal modem (Thanks Apple!! - we dont all send all our time in major metropolises)
I have read a couple of reviews stating the MA034Z apple modem does not work with the Intel processor in the MacBook Pro. Any substantiation?
Can anyone guide me to an external modem that works. I just need simple dial up - no faxing

Welcome to Apple Discussions!
I have the Apple USB Model MA034 external modem which I got when I bought my MBP in September 2007. I have used it for dial up internet ever since, and have had absolutely no issues with it. I use it for dial up both at home and when I travel. It works perfectly.
I find it hard to imagine that Apple would provide a modem that would not work with the MBP. It may be worth reviewing the reviews, and possibly posting a link so that their assertions about the modem can be evaluated.
Good luck!

External Hard Drive Issues using WD Passport with MacBook Pro

I am unable to view my external hard drive (WD Passport 160gb external hard drive model # wd1600me-01) with my MacBook Pro. I already tried using the Utility Disk application by utilzing the repair function and mounting it. Please help. Any Suggestions?

Im familiar with that HD, I have one currently disassembled for just the bare HD...., it has a removable SATA bridge, if the HD wont spin up but the light comes on, on the HD, then the SATA bridge is bad.
If it appears in disk utility and the light comes on BUT the HD doesn't spin up, then either the SATA bridge is dead, or the HD is dead (least likely).
Youd have to crack open the HD, remove the SATA bridge cart thats plugged into the HD and put the HD into an enclosure or a HD dock to get the data
those external HD use a 50 cent SATA bridge famous for failing. The curse of all the good HD externals is the junk 3rd party SATA bridges attached to them that crash and burn.
It doesn't matter it was used once and stored away for 5 years,.....HD lose their ferromagnetic properties at about 20-40% at 4-6 years.
And if stored in a hot place, a LOT more.

Using FCP 7 with Macbook Pro Retina Display?

Hi there
I am one of the many editor that won't be moving to FCPX and sticking with FCP 7 for the time being.
My question is has anyone used FCP 7 with the new Retina Macbook Pros ?
I'm basically looking to see it FCP 7 is useable on the retina display to help me to decide to buy one or not....My current Macbook Pro is nearly 4 years old and crying for an update but there a few concerns with the new model
1. Screen resolution is actually lower running FCP 7 and other software that isn't optimised for retina display?
2. No Firewire ports
3. No audio input
Any help really appreciated

FCP 7 is no longer in apples update lists so there is a chance that it has issues with the newer hardware (thunderbolt). I would guess there must be a firewire 800 PCIe card that could be used via a thunderbolt doc but how fcp is going to behave with it remains to be seen. Also FCP should not be able to take advantage of the retina display for the reason above.
Of course someone with such a macbook pro and fcp could always jump in this thread and clarify matters for all.
Good luck

Can't connect Canon MP560 wirelessly using Airport Extreme with MacBook Pro

My Canon MP560 is failing to connect to the access point. It recognizes the access point/network I would like to connect to but when I enter in my password it fails to connect and tells me to check access point settings. I used this exact same printer but different router in my old house and everything worked well! I'm thinking this is a Mac thing that I can't seem to figure out. I have the lastest Canon driver updates for Mac and use 10.6.8 software on my Macbook Pro.
This is how the printer instructs me on the panel.
a. Select Wireless LAN setup
b. Select Easy Settings
c. Select Access Point
d. Enter Password
e. Fails to connect..........
Please help.
Brice.

Hi Tesserax,
i have the same issue as mountie30 with the MP560 but it's not working
i have a airport express.
i was following your instructions:
''To get to this feature within the AirPort Utility, go to the utility's menu bar and first choose Base Station, and then, Add Wireless Clients...''
the problem is, base station is in light gray and i can't click on it.
i re-plugged my printer into my imac so it detects it again. (it still says printer offline in settings)
i have no clue what to do.
please help
thanks

Possible to use IR Modem with MacBook Pro?

I am a new MacBook Pro owner who travels frequently to a variety of locations.
I am interested to see if I can use a PSION Travel Modem (an IR Modem) as a backup for those instances where WiFi just isn't available.
(Believe me, I will travel to such locations.)
I have used this nifty modem ( http://www.amazon.com/gp/product/B00004RKHF ) with my Palm in the past. I have done quite a bit of searching through Google & this forum, but have not found a specific Psion modem script or a generic IR Modem script to try.
Can anybody point me in a direction to get this working?
Thanks,
Brad

Apple has not included Infrared output on their Macs since 2001. You'd have to find a Mac compatible USB or ExpressCard 34 adapter for Infrared. I don't know if it is possible to reverse engineer the Infrared of the Front Row remote, but that's the only logical means I can think of making it work if it were possible.
I'd get a 56k modem, if you want an alternative to WiFi:
