Jitter wave flicker snow on MBP 17 i7 external DVI and VGA adapters at 85hz
On with the mini displayport to VGA adapter I'm getting an intermittent jitter (it's like a tight waving that goes up the entire screen) on external displays. Using the DVI adapter I get intermittent snow (like analog TVs used to show when you had no antenna, but very high rez).
On the VGA adapter at 85hz (my usual preferred refresh rate) this happens very frequently. At 90hz a little less so, and at 75 or 60 it doesn't happen at all so far. On DVI it was always set to 60hz.
Both of these problems don't stop until I unplug the adapter and plug it back in again. The VGA jitter comes back sooner though. Since I haven't found anything like this on the net, my own fix has been using VGA at 75hz and being lucky enough to be able to use a mini-displayport to displayport cable instead of DVI.
Why would it do this? Has anyone else had this problem? Is this a software, hardware, or firmware issue?
I've had the same problem with the following setup.
MacBook Pro (Eearly 2011) 17 inch / 2.3 GHz Core i7 / 8 GB RAM / Mac OS X 10.7
EIZO FlexScan S2000 (1600 x 1200 / 60 Hz)
Apple Mini DisplayPort to VGA Adaptor (firmware version 1.03)
Basically, I've got a jitter (see the attached image) on the external display after 10-30 min.
I have replaced the adaptor with a new one at the shop, but the new one has the same problem.
Interestingly, though, the same adaptor with the same firmware version 1.03 that my company bought a while ago doesn't have this problem.

Mini DVI to VGA incorrectly shipped with MBP instead of DVI to VGA
Has anyone else had a mini DVI to VGA adapter shipped with their macbook pro (2008) instead of a DVI to VGA adapter? I just needed to use it today and was told at the apple store that I had an adapter included with the computer. I went home to check and the adapter that was with the computer was a mini DVI to VGA adapter and the computer has a regular DVI output. I understand that later in 2008 the mac book pros were made with the mini DVI so I am thinking that there may have been a packaging error.......unusual for Apple???
Hi Tingrin,
Most likely an error when the machine was packaged for distribution. The MacBook Pro has never shipped with Mini DVI, it was a dual link DVI port until they went to Mini DisplayPort. The MacBook, however featured the Mini DVI.
I know Apple has ceased to ship the adapters with the MacBook Pro, to my knowledge they did around the time of the mid/late 2008 machines. I know with the first couple of generations (MBP) you actually got both a DVI and VGA adapter.
I'd contact Apple, inform of the discrepancy and I'm sure they'll make it right. -
MBP CD2 DVI to VGA not working with projector
I am having issues getting the MBP to recognize a DELL 2300 projector through a DVI to VGA apple cable.
A few months ago there were posts about this, but no solutions. The problem seems to be with the 'INTEL' side of things, as the same projector with the same DVI to VGA apple cable works on an older G4 tower running 10.4.9. The projector also works on an old G4 iBook with it's version of a VGA adapter. To make things more confusing, a DVI to Video apple cable works with the DELL 2300 on my new MBP C2D-but produces a terrible quality picture. Mysteriously, my previous 1st generation MBP CD worked with the DELL 2300 via a DVI to VGA apple cable (but I'm not sure which OS was out at the time 10.4.8?)
My new MBP CD2 definately recognizes the projector through the DVI to VGA adapter, but the projector doesn't recognize the video signal from the computer. It is DEFINATELY the MBP (or universal drivers), as I have checked the DVI to VGA dongle (works), have checked the projector (works with an ibook running 10.4.8 OSX with VGA dongle), have changed resolution settings before and after connecting, have restarted computer, have tested various orders of connecting the projector and cables. STINK! (I also have TWO DVI to VGA adapters, so it is not a bad adapter). I have also played with exchanging various plist files from older universal versions of 10.4.8 that worked with the projector-no help.
As I stated, the projector will work (in horrible quality) with a DVI to Video dongle. Why it will not work with the DVI to VGA dongle is a mystery and annoying I would hope that a newer MBP CD2 would be plug and play (like my previous MBP CD and an old G4 tower and an old iBook G4...but no).
Any ideas, any help, any answers?Here are the actors in our play today
1. MacBookPro A. (my system a CD2 2.16 with OSX 10.4.9)
2. MacBookPro B. (my friends system a CD2 2.16 with OSX 10.4.9)
3. an iBook (my friends 1.07 GHz G4 with 10.4.8 and a VGA adapter)
4. DELL 2300 MP projector
Plugged in DVI to VGA adapter to the virgin MacBookPro B (never had the projector plugged into it before) Dell projector shows that it recognizes an analog RGB 800X600 signal from MBP B. It projects a beautiful desktop. All is well for a moment.
In Display preferences we see for the MBP B
Color LCD, Display: 800X600 stretched, Colors: Millions, Refresh Rate: N/A
VGA Display
Now, I unplug the DVI to VGA adapter and naturally MBP B readjusts to it's native resolution. Great.
Now I immediately plug back in the DVI to VGA adapter. The computer and the projector searches for signal with none found, while the computer shows no attempt at an automatic readjustment as above (800X600 stretched).
I try the 'detect display' option. It causes computer to stall for a second (as it searches) but it does not detect projector and does not readjust it's own resolution to 800X600 stretched as it did initially. F7 key does nothing.
This is a problem!
So, I shut down the projector. I unplug the projector's power source and waited 20 seconds. plugged it back in, started projector back up.
I shut down/restarted the MBP B.
I plug back in the DVI to VGA adapter into the MBP B. The MBP B screen flashes to all blue, but does not automatically change to 800X600 stretched (remains at native resolution and does not recognize an external monitor/projector)
Enter the iBook!
I plug the iBook's VGA adapter into the projector. The projector shows that it recognizes an analog RGB 1024X768 60Hz signal and projects desktop screen immediately. Plug and play!
iBook display prefs reveal:
Color LCD, 1024X768, colors: Millions, Refresh rate: N/A
Color tab: Generic RGB Profile
VGA display, 1024X768, colors: Millions,
Now. I unplug adapter from iBook, iBook readjusts to native display
plugged back in adapter to iBook, immediately recognizes and displays projected desktop.
Scene 2: The FREAKY thing!
Now, I immediately (after unplugging the adapter from the iBook) change adapters to the DVI to VGA adapter and plug the projector into the MacBookPro B, whallla! Back in business. (computer screen adjusted to 800X600, and projector recognized signal).
Now, what about my computer? I unplug from MBP B and plug into MacBookPro A, and NOTHING...the computer doesn't automatically adjust to a new resolution, and the projector doesn't recognize any signal from the computer.
Ahhhh Freak out! Now, I plugged adapter back into MacBookPro B, and now back to NOTHING. MBP B no longer recognizes projector or readjusts it's resolution. Was something somehow corrupted?
Now, I plugged iBook VGA adapter back in, and iBook once again with it's awesome G4 technology (or dated video drivers or something) recognizes the projector in an instant and projects the screen.
Now, logically I try again to immediately unplug the adapter from the iBook and switch adapters and plug back into MacBookPro B-it worked once right? But, sorry, NOT twice. The mystery deepens.
Well, I think, maybe it is because I didn't restart MacBookPro B before attempting the switcharoo from iBook to MacBookPro.
So, I plug back into iBook-projector. And the iBook works immediately again.
I restart MacBookPro B and plug in to the freshly restarted MBP B...HOUSTON WE HAVE LIFT OFF! The MacBookPro B recognizes the projector and the projector kindly displays the desktop.
Now what about MacBookPro A...Last time, when I did the switcharoo, it corrupted something to cause the MBP B not to work. Let's try it again. Will this plug-unplug-restart-switch adapters-immediatly plug in technique work...let's see. I restart MBP A, and plug DVI to VGA adapter in. Sorry. Same ol' no signals recognized. MacBookPro A not auto readjusting resolution, and does not list any projector in display prefs.
Let's get crazy and immediately plug the adapter into the MacBookPro B...it works-oh so logical...NOT! Why wasn't it corrupted this time by MBP A? MacBookPro B readjusts its screen to 800X600 stretched and projector immediately recognizes and projects desktop.
Now lets see if I can break it again as before. I unplug it from MacBookPro B and back into MacBook Pro B, knowing that this caused it to stop working previously. And...it still works-WHAT? I do it a third time. It still works on MacBookPro B.
So,
I plug it back into MacBookPro A...still nothing. Back to MacbookPro B works like a charm. This time it struggles a bit showing that initially it sees a signal from MacBookPro B of 1192X900 (i Think), then the MacBookPro B switches automatically to 800X600 and the projector works.
Wait..I see something amiss! I see in my MBP A menu bar an icon for Labtick which MBP B does not have. I shut down Labtick, plug back in the DVI to VGA adapter and 'Boom' the projector is recognized.
I unplug DVI to VGA adapter and plug back in to MBP A and 'Boom' the projector is recognized again...no it couldn't be!
Well, it is possible it couldn't be because, I shut down the projector, unplug it's power source, plug it back in. I plug it back into the recently working MBP A with Labtick not running, and sorry folks, now the projector doesn't work again. The MBP A does not readjust it's resolution, nor recognize a projector and the projector doesn't recognize the MBP A.
Let's try the projector in MBP B....same deal. Now it doesn't work. Same symptoms of MBP A.
Back to the good ol' iBook. Of course it works.
Now switching over directly to a restarted MBP B. -DOESN'T WORK (as it did using this technique previously)
Now switching over to MBP A- DOESN'T WORK.
As you can see, it is hard even with multiple computers to find a series of doing things that consistently makes the projector work.
Any thoughts, ideas, ways to diagnose? Thanks! -
Mini-DVI to VGA flicker with Snow Leopard and 2nd monitor
I have a 24" iMac (fall 2007) and recently purchased a 26" Vizio (VMM26F10I) and connected it as a 2bd monitor for my iMac using the Mini-DVI to VGA adapter Apple sells.
The new monitor will flicker now and then and some times will go to no signal. I have to change resolutions to something else and then back to standard setting to get it to come back or unplug adapter and plug back in.
Is there a fix for this?26" VGA...? Which resolution/frequency? Have you tried a fresh cable with clean connectors, etc....
What did Vizio say when you contacted them with this question about your new purchase? -
I have a MBPro mid 2013 with 1 Thunderbolt port. Just bought a Mac monitor and want to daisy chain a PC monitor to it. Use a Mini DVI to VGA adapter from MBP to PC monitor. How do I daisy chain the 2 monitors?
Hall Palm Desert,
if your Mac monitor has Thunderbolt ports, and the PC monitor is on the end of the daisy chain, then you might be able to do it by connecting your PC monitor’s VGA cable to a Mini DisplayPort-to-VGA adapter (e.g. Apple, NewerTech), connecting that cable’s Mini DisplayPort end to one of the Mac monitor’s Thunderbolt ports, and then connecting a Thunderbolt cable between the other port on the Mac monitor and your MacBook Pro. -
Can I purchase Mountain Lion and make a flash drive bootable? I do not want to install it on my Macbook Pro. I have Snow Leopard on my Macbook Pro now, and due to my hard drive needing repair, I need to boot off of another source, like my flash drive. I am in Paris and my Snow Leopard DVD is in Texas.
Mac OS X has a built-in disk diagnostic and repair program called fsck or file system consistency check. Here’s how to verify and repair your startup disk with fsck. As soon as you hear the startup tone, press and hold Command-S on the keyboard. Keep holding down those keys until you see a black screen with white lettering. This is called “booting into Single User Mode.” As the Mac boots in this mode, the screen reports each step of the process. The line should end in root#. Right after the root# prompt, enter the following: /sbin/fsck -fy
If repairing the disk in single user mode fails, it means one of two things. Either your hard drive itself is failing (a hardware failure), or the directory damage on your hard drive is beyond the capability of the built-in repair procedures in OS X. -
I have a older MBP running 10.6.8 and after the recent iOS update I have not been able to sync my devices. I was able to sync an ipod, but not iphone or ipad. iTunes recognizes my devices, but sync button stays grayed. I've changed my USB hub, reinstalled iTunes and run disc cleanup. No luck.
You said that your computer will sync other iPods? Are they iPod touches? Other iPod use different drivers the the touch And iPhone and iPad).
You can try:
iOS: Device not recognized in iTunes for Windows
Does it charge? Does the iPod work?
I would try on another computer.
Last, make an appointment at the Genius Bar of an Apple store.

I recently (Jan 2012) acquired a MacBook Pro (MBP) running 10.7.4 and an AirPort Express. I also have an old PPC G4 tower (Digital Audio model) running 10.4.11. The OS software on both machines is totally up to date. AirPort Utility on the G4 is 5.4.2 and on 6.0 on the MBP. I bought a used AirPort card for the G4, I believe it is 802.11b compatible, and the wireless data rate is specified at 11 Mbps. Being a newbie to wireless, it took me many days to get these two machines to link up. This network is not connected to the internet, and there no other networks in the vicinity.
My last problem to solve is the very slow file transfer speeds between the two machines. The transfer time seems to vary depending on which machine I use to initiate the transfer, and which direction the transfer is going. For example: If I initiate the transfer from the G4 and send a 5.4MB file to the MBP it takes 1:32 (min:sec), while the same file going from the MBP to the G4 takes 27 seconds. On the other hand if the transfer is initiated on the MBP, going from the MBP to the G4 takes 2:56, while going from the G4 to the MBP takes 1:59. I realize that these times are not actual wireless transfer times but includes the entire transfer process.
Both machines and the AirPort Express are within a 4-foot radius. Both machines are set to radio channel 2. The AirPort Express is set for 802.11n(802.11b/g compatible) with WPA/WPA2 Personal wireless security.
Any help would be appreciated.
CEU2BDAqua,
Thanks for the response.
Apple has used the term "Digital Audio" to identify this machine. System Profiler has the following information:
Machine Name: Power Mac G4
Machine Model: PowerMac3,5
CPU Type: PowerPC G4 (2.1)
Number Of CPUs: 1
CPU Speed: 800 MHz
L2 Cache (per CPU): 256 KB
Memory: 768 MB
Bus Speed: 133 MHz
Boot ROM Version: 4.3.3f2
Serial Number: XBxxxxxMK9
Sales Order Number:
Yes, I could connect them by ethernet if all I wanted to do was transfer files, but I would like to network them so I could use wireless internet. The machines are not always so close together, I did that to simplify the testing. With the very slow transfer speeds I am reluctant to move ahead with the internet step.

Hey i bought a brand new MBP like 6 months ago and now it won't charge
i bought a brand new MBP like 6 months ago and now it won't charge. I tried using a friends MBP charger of the same year as my computer but it still says not charging at the top right corner of the computer screen where the charging symbol is.

Is it possible to connect MBP as a external disply from macbook air
I have both a macbook pro and air, my MBP is 15" and air 11"
i was wondering if its possible to use my MBP 15" as a external displly like "another/ seperate" monitor
i thought of two ways of possibly connecting them.
1, buying a thunderbolt cable and hooking them up and hopefully lworking
2. buy a thunderbolt-VGA, get a VGA cable, and VGA-mini disply port
not sure if theis would work but really want to use my MBP as a disply.
any answers? thanksDue to the form factors, I wouldn't think it would be a good fit to use a 15" as a monitor even if it were possible. You can get an bigger monitor that would work for around $100. That would be my solution if you wanted a bigger display from your 11" MBA.

I have recently updated my OS from Leopard to Snow Leopard but now my external hard drive and even my iPhone are not recognized by my Macbook Pro! Anyone have a suggestion??

I had iLife pre-installed on my aluminium Macbook 2009 with OSX Leopard on it. My hard drive broke but got most of the info off it and just installed snow Leopard on to a new drive and then downloaded and installed Mountain Lion over it. Now I don't have iLife anymore. How do I get it back?
Welcome to Apple Support Communities
Mac OS X doesn't come with iLife applications, so you have to install them manually after installing Mac OS X.
Insert the Applications disc or Mac OS X Install Disc 2 DVD and install iLfe applications. Then, open > Software Update, and install the latest update. If you want, you can purchase iMovie, GarageBand and iPhoto in the App Store, so you will get the most recent version -
My MBP keeps freezing with red and black vertical lines. What's going on?
About once a week my early 2011 i7 macbook pro seems to freeze with these weird lines on screen. I was using Adobe Photoshop CS6 and had quicktime playing an mp3 in the background. Nothing out of the ordinary happened that I know of that could have triggered the computer locking up.
I took my MBP to the Apple store and they said it passed all diagnostic tests. They suggested that since it is sporatically happening, it may be weeks before an answer is given to the problem that I am experiencing. Here are some pictures I took when my mac last froze.Were you ever able to resolve this? My friend's early 2011 MacBook Pro with your same specs except with 10.6.8 just did the same thing while Google Earth 7.1.2.2019 was running. Never any other issues, just happened out of the blue.

Santa Rosa MBP - DVI to VGA Projector problems
When hooking up a Sharp PG M20X using a [DVI toVGA cable] and a [VGA to DVI adaptor] the MBP sees the projector, but the projector cannot see the computer.
This is a problem because, I may find myself in situations where this is the only configuration for hooking my MBP up to a projector.
Note:
1. A G4 Powerbook works fine with this configuration.
2. The MacBook Pro drives the Sharp PG M20X projector DVI to DVI - without problems
3. The MacBook Pro drives a DVI to VGA CRT monitor - using a [VGA to DVI adaptor] - without problems.
Is there a solution?
Thanks
I have a 2.4 GHz Santa Rosa C2D MacBook Pro Mac OS X (10.4.10) Sharp PG M20X Projector (DVI-input)I think I solved this problem.
It was in issue for me. My second monitor would only display the Windows XP screen when it was loading, then it would black out. I couldn't even move my mouse arrow to the other side. Then I fixed it, here's how (running Windows XP SP3):
1. Start > Control Panel > Appearance and Themes
2. Display
3. Go to tab "settings"
4. Double click the blue image with the "2" inside it. This is the second monitor, adjacent to your first, or primary, monitor. The blue box may be a desaturated, greyish blue, meaning that the monitor is disabled. Click it and it a box will pop up asking if you want to enable the monitor. Click OK, and then like magic, your monitor is resurected in it's Windows Glory! From there, adjust the resolution, and it should work perfectly.
This isn't a Boot Camp compatability issue, it's just a problem with the lack of familiarity that users of OS X have with using XP.
Have a nice day!

I would like to have Snow Leopard, Mavericks with built-in recovery, and Windows 7 (Bootcamp) on my iMac (Intel). Is this possible? If so, how? Currently, I have Snow Leopard and Windows 7 (Bootcamp) running on my iMac. I have enough disk space to split my Snow Leopard partition. I have read that if I split my Snow Leopard partition, clone my Snow Leopard partition to the new partition, and boot to the new partition, that I may have problems with the Maverick's upgrade because it may not be able to create the recovery parition, or that it may erase the Windows partition, or that it may mess up the Windows boot process.
Simplest is to install Mavs on an ext HD, using FW or TB. I don't do windoze, so can't advise about the Boot Camp and multiple volumes issue. Since there's no Boot Camp, I have four volumes running SL through Mavs.
