PowerPC :: Display Vibrating Slightly When G3 Moved
Dec 4, 2006
This is going to date you all a lot but I have a powermac g3 (640mb ram, 300mhz) with a 15" apple crt monitor. I moved it into a new room and all of a sudden the display is virbrating slightly. If I switch the refresh rate back to 60 it goes away but then that looks so bad that I have to bump it back up to 70hz. Is there any settings that I can change to fix this vibrating? Like I said, this didn't happen until I moved the computer 20 feet into a neighboring room.

I just turned on my mid 2009 13in Macbook Pro and noticed my display seems about 4 'clicks' dimmer than before. Everything else works fine. Can LED screens dim over time? Could my LED driver somehow have caused the screen to dim? Can just the LED portion of my display be replaced?

MacBook Pro, Mac OS X (10.7)

My tibook .867Ghz was working fine this morning, but now when I restarted it this afternoon, the colors are all off (lots of green and rapidly vibrating pixels in background). The computer works, I can run programs and so forth. There are no changes to the displays settings, still 1280x854 and colors "millions". When I switch to thousand or 256 colors there is no significant change.

I was thinking, for the next generation MacBook Air, would you want a slightly thicker (thickest part is 0.9in, tinnest is ~0.35in) laptop with a built in Superdrive, more ports, etc, or would you perfer that Apple moves away from this with a thinner computer (0.1in thinnest, 0.6in thickest), but with same limited ports.
I would actually perfer thicker with a superdrive, since I want an air but I want it to be like a MacBook but thinner. What do you think? Btw, this is assuming the regular MacBook does not change in size, since that would sway peoples opinions.

My ibook g4 (about 15 months old) switches itself off when I move it. Then have to force turn off (holding start button down for 10 secs). I then have difficulty turning back on, in that most off the time the fan just starts, with no startup noise, and the computer just doesn't turn on except the fan. After a few tries it eventually works, but its hit and miss. Its my first mac and I'm really scared something major is wrong that will cost a fortune to fix?

I was given an old ibook G4, with a borken hard drive.
since it would boot from a firewire drive on mac os X 10.4 ppc, I decided to change the hard drive, which i had never doe for a laptop. I had a very similar 40 Gig toshiba IDE drive from an old laptop, opened the ibook and changed the drive.
everything works, the mac boots fine, sound, video etc, yet I realised that it had one rather serious issue. It shuts down when moved / tapped, even very lightly, and this is problematic for a laptop. I was considering buying an airport extreme for it, but now I'm afraid this might not be mendable, nd i'm reconsidering.
what could be wrong ? is there somekind of shock sensor that could have been damaged ? I put back all the screws, and only changed the drive and proceeded cautiously, but maybe something was damaged- what could be causing this, is there a specific area I should focus on ?

As the title says, I need a new monitor for my old G5 as the old monitor for it went bust. Apple does not make the old displays that came with the unit anymore and the only available monitor is the new LED ones ? but they all come with mini display ports

For the past few months i have been using an external display hooked up to my 12" powerbook g4. I have had it on a dual display mode so no mirroring. Recently i would open the laptop lid waking it from being in sleep mode and my internal display will not turn on. The apply system profiler does not even recognize that the internal display exists. My external display works fine and has always been set as the main display. If i go to detect displays nothign happens. I have tried restarting the computer, instering system disks, unplugging the external and nothing has worked. I simply cannot get my internal screen to fire back up. When i used to unplug my external display the internal display would switch back to being the main display and everything would be fine. Now i cannot get the internal display to function whatsoever. Please try and help me as a need this laptop working and i will be ordering a mac pro soon for use with my external display.

I am looking for a display to use with my Powerbook G4 12". I am in love with the 30" cinema display, but according to technical support today, my setup is not compatible (supposedly, but the person on the phone didn't sound to sure). I have a mini DVI, but the 30" requires a dual DVI. I think the 23" display requires DVI, which I can attain with an adapter. Does anyone have suggestions for what I can use with my computer? The bigger the better for me. Also what do you think of the older (plastic case) apple displays?

Well, I have a late 2008 13" Macbook Aluminum, (I've had it since Christmas of 2008) and just yesterday, I noticed a weird buzzing-like sound coming from the inside of it. There's also a faint vibrating feel to it. I felt around, and the vibrating feels like it's coming from under the middle of the keyboard more severely. The buzzing occasionally sounds like it's getting faster, and then slower, faster, slower, etc.

Mac-mini, OS X Leopard: Suddenly my wife's Leopard Mac- Mini (monitor) screen shows a 'vibrating' display that is split into three distorted parts. I can see it is the Finder shown three times. Fixing Permissions does nothing. Is this a hardware or software problem?

iMac Flat-Panel G4 1GHz, 1.25GB Memory, Built 2003, OS 10.4.11: the 17" flat-panel display has developed vibrating vertical red lines. I have saved an iMac G5 that died; can I use it just as a monitor for my G4?

My Macs been opend up at apple recently to replace the trackpad - Now i notice the internal speakers seem to be causing the keys on both sides to vibrate at certain frequencies and causing very noticeable distortion. even a simple Skype conversation becomes really bad quality because of the distortion - is this common? Can it be solved in Apple or is it just what Mac speakers are like? I dident think it did it before they opend it up.

Why does it seem like my eMac display looks nicer than my iMac display? I always wanted to know or am I tripping?

I'm getting this horizontal bar that changes colors and sometimes the whole screen image looks like it is vibrating rapidly up and down, I'm utterly at a loss. The model in question is an Early '09 with the 9400M IGP. It just randomly started last night. I've already had a video issue that got fixed, I think it was the GPU

When my new i7 is on my usual desk (where iMac 24" white stood silently before), it sounds like a dishwasher. Or a plane engine. The low, loud vibrating noise drives me so mad I snap. It penetrates my very brain and makes it vibrate. It's audible from another room. In desperation, I raised my Mac and the sound stopped. I put it on the floor, and the machine is silent. Back on desk - airplane engine sound again. What the heck? My desk has been perfect for all my other computers, what's so special about i7?

I was playing a bunch of 1080p videos when I started to hear a vibrating/buzzing/rattling sound coming from my Mac Pro. I don't recall ever hearing this sound before. Is there something wrong with my Mac?

Yesterday I have noticed slight change of colors on my iMac 27 inch monitor. The change was really subtle but newer the less important. I'm an illustrator and I use subtle textures and brushes in my work. Yesterday suddenly, those textures were not subtle on some pictures on my web site but really noticeable. Especially on black on black textures (when you have different shades of black/gray). I thought that the mistake is coming from Safari browser, but the same thing was visible on the Chrome too and when I opened same pictures like jpeg with Preview or Photoshop. After that I noticed that generally all display was slightly brighter, slightly more bluish. I didn't do anything unusual to make it that way. Today, after putting iMac to sleep and turn it up again the colors are like they used to be and it seems that problem is solved. I would like to know what went wrong with the display/monitor, because I have worked all day yesterday on my illustrations with wrong display of colors and now I will have to correct them today.I have run Profile first aid with ColorSinc but result was that everything was ok, no problem find.

Actually I find this drive slightly noisy, not too bad but you can definitely hear it spinning and clicking every so often. Anyone else experience this or should I be worried?

I noticed my Macbook White (late 2009 model) right speaker is slightly louder than the left one. I have checked the sound balance on my sound setting and its set to balance. Some things I have noticed when playing with the settings. When i shift the balance to the left, there's sound on the right when it's not supposed to. Then when I shift to the right, the left speaker is quiet. This problem seems to happened on older Macbooks - [URL].

My lid seems to overhang very VERY slightly over the left side of the case. I got some people in my family to look at it, and they honestly don't even notice it. The distance is the thickness of a piece of paper. So small it is barely noticeable when looked at, but you can feel a slight difference when you rub your finger over the edge. Should I be concerned about this? I would take pictures of it, but the Macro mode on my camera isn't good enough to properly show this issue. Go Figure... Will this affect hard shell cases? I've also learned something. People that are O.C.D. really have a hard time enjoying their Macs. Seems like we spend more time scrutinizing every square inch of our equipment that we actually spend enjoying it.

I'm the owner of a Macbook Pro with 4 gig RAM and a 320gb harddrive. However, I have noticed that the hard drive space is decreasing slightly for seemingly no reason. Case in point, today it went from 197.66gb to 197.50 whilst I was watching TV and just before it went down further for no reason whatsoever.
Although its not a big deal it does arouse my curiosity and annoy me. Is it just virtual memory that will eventually come back or something more sinister? If it continues for a long time the space lost will eventually add up. Since I'm planning on soon buying an iMac these are the sorts of things I need to know.

The glowing Apple Logo behind the screen seems to be glowing a slight purple colour, but mainly white. Is this normal due to the screen being so thin?

I have a fairly recent 17" MBP and I've discovered today that the headphone socket is a bit looser than I'm used to. My usual headphones click in as usual, but very little effort is required to pull them out. I have recently been using a client's cable to hook my MBP up to their speakers, and I have a feeling that the 3.5mm jack (which was a fairly tight fit) has somehow worn the socket.
Is it possible that using a slightly 'fatter' jack can damage a socket like that? I'm a bit wary of people plugging their cables into my laptop now, as I don't want to exacerbate the problem! Anyone else experienced this?

I created my website with iWeb 1.1.2 & have had absolutely no issues with it from running Tiger right through to Snow Leopard (10.6.2) which I am running at present. However, in the past couple of days, I have noticed a few strange issues with a few of the images...they appear to be slightly out of focus...not only on photographs but also on parts of my website whereby I have added text & these are then saved as PNG files. I haven't changed any preferences whatsoever & everything appears as it should within iWeb itself.
The issue is only occurring once I have published to a folder. I've emptied the Cache in my Browser but the issue is still there. I've added a link below to an image which shows the problem I am having. The top & bottom appear as it should however the centre appears very soft. It doesn't appear like this within iWeb, only once I publish the files. [URL] Would it be worth deleting the preference file for iWeb, & then relaunching the application?
