I have an '07 vintage (DVI) Mac Mini I use as a media center. I haven't used it in a few months & its been shut down during that time. I went to start it up today & the power light went on & I could hear the fan start up but no start-up chime & no video.
I did an PMU reset to no avail. I'm thinking the logic board is done (it's under warranty & I have an appt. with a "genius" tomorrow). Just wondering if there is anything else I should try before I bring it in.
My mini "starts" without chime when I press the power button on the back. The fan starts, the light in front goes on and I hear some clicks which could be the hard drive. The screen remains black (no signal) and the mini does not respond to the USB keyboard power button. It does not start when pressing it and will not power down if I press it for any length of time when it is on. Pressing the power button on the back for some time shuts it down.
My Mini powers itself down before it finishes booting.
It's a 1.25Ghz G4 Mini, so it's a few years old. As of the last few days the computer turns itself off. So I push the power button and I get as far as the grey screen and I see the circle logo rotate and I can hear the disk heads seeking if I place my ear near the Mini. But before the OS boots, while the screen is still grey the Mini powers off. It does this with the recovery DVD in the drive too. Either way it never boots
My first mini has a problem. It will power on with the light and then promptly turn off in about 3 seconds. The hard drive spins up but the fan does not turn on. No image on the screen or anything. the mini is open for diagnosis and will do the same thing if the CPU is not installed. Interesting question what will a mini do when it is powered on but doesn't have its CPU installed?
Ive got a G4 Power Mac 2x500MHz that Im getting a bit frustrated with.
Situation: - Power supply seems to work as power flows once I hit the power button. Fans spin, red light comes on the board, connected drives spin up, drawers open. - No chime. At first it was sporadic, but now non-existent. - No video output. Has the original AGP ATI 128 Rage Pro graphics card. - No power to USB ports? Try plugging in devices that light up in USB but nothing happens.
What Ive tried: - Ive replaced the board with a known good board and get the same results, and of course i thought this was the main problem. I did get a tiny whiff of burning smell from the previous board, though no signs of physical defect on it. No smell from the new board. - Replaced and swapped around about 6 different ram sticks. - Tried PCI graphics card (probably not compatible though) and no results, as expected. - Reset PMU of course. - Swapped processors.
I have a 400 mhz Titanium powerbook I'm trying to resurrect for my teen daughter. Just replaced the internal pram battery, the external regular battery, and the a/c cord, all with brand new parts. The book was dead, and now I have power but not much more.
When pressing the power button I get one chime, and then I can hear the fan working, but no hard drive sounds. The screen is black.
Eventually, when left sitting, the thing will turn itself off. It seems as if it is not booting completely, but then I can't see anything. I am used to hearing hard drive pops and whirrs though, and nothing here.
1. I tried resetting the PMU with the button on the back of the unit. 2. I tried resetting the pram with cmd/opt/p/r before power, but no matter how long I hold I only ever get one chime. 3. Tried booting with my OS Tiger retail CD (which is what is installed) and the drive barely spins, and the screen remains black. Holding C doesn't help. 4. The new battery is charging normally. 5. I tried removing the two ram sticks, moving them around from slot to slot, and using one ram or the other. Nada. 6. Tried forcing shutdown by holding power button 10 secs, then rebooting. In fact, that's how I have to shut it down when I need to, since I can't see anything.
This laptop has been in storage for about a year. This is the same problem I had when I put it away. I think perhaps the laptop might have been knocked off the coffee table and fell about 2 feet to the floor a short time before these problems. I heard it, but the kids won't admit it. *grin* It worked fine for about a week or so, then began losing video at startup.
I just spent about $75 in parts. Should I maybe try a new PMU board before chucking the thing? Any other ideas what might be happening?
I've read till my eyes are blue, and can't seem to find a boot issue with one chime on this machine.
Just a warning, I bought a Mac Mini (2009) and wanted it to hook it up to my TV. My TV does not have HDMI or DVI inputs so I bought a Mini DVI to Video adapter from Apple.But I could not get it to work, then I googled for it and it seems this adapter does not work with 2009 Mac's since it does not output an analog signal anymore!

So anyone that wants to hook up his new Mac to an older TV set with the Video adapter, you are warned.I guess i'll have to buy a Mini-DVI to VGA adapter and then a VGA to SVIDEO converter..
When I plug my Intel iMac into our old Sony Trinitron via the S-Video input no connection can be made. Is this a problem with leopard not recognizing my TV or possibly something else?
Just bought the new mac mini with HDMI out - 2.66Ghz, 8 Gb RAM, 500 Gb HDD
A lot of mkv or avi files I playback appear pretty choppy in VLC - my primary app for watching movies and tv shows.
I have a Drobo with two 2 TB SATA drives where I store all my stuff and which is connected to my mini via firewire 800.
I've tried playing the same video back from both the Drobo and from the internal hard drive, to see if the choppiness was on account of the external drive or not. No difference really. A choppy video remains choppy from either place.
It's pretty strange because some 1080p videos play just fine, with no choppiness whatsoever, while other 720p videos or even standard definition divx files are still choppy.
I have an older MBP (1.83 Intel Core Duo) When I push the power button, I hear a little electric noise, then a fizzle noise. It won't turn on. However, if I close it almost all the way and turn it upside down, it powers up fine. Once it's running, no issues. Any idea where to start with trying to correct this problem? I don't know what part could be making this happen. And yes, it has to be both upside down and almost totally closed.
Lately i've been coming home to find my imac on. I've been shutting it down due to all the thunderstorms in my area. Under the energy saver options, wake for ethernet... isn't checked off. I do run eye tv but i dont have anything scheduled. Is there anything else i should check? I have an external hard drive and printer connected to the usb ports. It's an intel imac, 5 months old, 1 gig of ram and running the latest version of leopard.
After a forced power down my iMAC won't boot again.
The machine simply powers off after the spinning gear on the gray start up screen spins for a few seconds.
I've tried booting in safe mode, doing a PRAM reset and inserting the Installer DVD but I don't even get to any of these steps and the machine turns off.
I have a 2009 macbook pro unibody, I just replaced the battery but my macbook pro 2009 powers off unexpectedly. Sometimes while its plugged in and other times when running on the battery, when it gets to 67% life left it powers down. What is causing this and how can I fix it. I have already had a brand new battery put in it. I am running Mavericks OS currently.
Problem: powers up, will not complete start up sequence What led to the problem: Ignorance, mostly. CD was stuck in vertical bay and I tried someone's suggestion to eject via terminal. If you are laughing (and/or groaning), you know what must have happened. Here are steps taken to rectify disk eject and start up problems, with the results. Note: iMac install disk one remains in the vertical bay, unable to be read or ejected. applejack, fsck -fy ... multiple times. Results: disk & permissions repaired and/or verified but OSX still will not start up. It starts with grey screen, goes to blue with grey window. Progress bar moves slowly from left to right and seems to reach 100%. Operation stalls at that point. Note: Any attempt to use diskutil stalls and commands such as list, mount do not execute. drutil eject gave these results: dyld library not loaded: /system/library/Frameworks/OpenGL.framework/versions/A/openGL referenced from: /system/library/frameworks/QuartzCore.framework/versions/A/Quartzcore reason: image not foundTrace/BPT trap
I have a recently-purchased MBP Retina 15 inch from Mid 2012.
Every time that I put my laptop laptop to sleep while it is on battery, it sleeps fine for about an hour. After an hour or so, I hear the boot sound come from the laptop. When I open the screen at that point, the laptop is powered off. I have to power up the laptop. The laptop is not in hibernate mode, but has actually shut down (pressing other keys on the keyboard doesn't wake it up, I have to use the power button).
Applications start back up when I log in, however for example VMWare has rudely powered off (so I lose the state of my virtual machines), and any terminal programs that I was running (even if I just had a document open in 'vi') are also terminated.
I wonder, what causes this behavior? Is my system defective in some way, or is there an OS tweak in Mavericks to stop the computer from rudely powering off/force quitting all open apps in the process?
I've read that OS X now likes to hibernate laptops after an hour, but clearly hibernation isn't what's happening here.

My early 09 MBP just started having trouble with the USB port closest to the audio in/out. That port powers on my USB gadget, but it doesn't work. i.e. my mighty mouses laser turns on, but doesn't work. Anyone else having trouble with this?
Fairly new MacBook Pro with OXLion. When I try to turn on the computer, the startup noise and screen appear (grey loading screenwith apple icon). A loading bar at the bottom of the screen fills about a third up, then the computer shuts down again.
My 2014 21" iMac powers itself down after about 10 seconds while trying to startup in safe boot mode. I'm not even sure why it is trying to start in safe boot mode. I shut it down after a power outage while plugged into an APS UPS. I'm guessing that since I interrupted the auto shutdown it is restarting in safe boot mode. Either way, I get a grey screen with a big apple and a progress bar. The progress bar gets to about a tenth full and the power just shuts off.
I've tried starting up while holding the alt key to select the Macintosh HD. The same thing happens.
I have an acer 20" lcd and it has dvi-d, is that causing issues with the mac mini or is the logic board probably bad? it works on every other unit i plug it to.
Im thinking of completing the mac transformation from work and laptop to my home computer, does anyone know, does the mac mini have a good enough graphics card to play HD video thats downloaded, my current PC's graphics card struggles.
I knowits due for revision so going to wait for that. Say the new mini has the same GPU as the current mac book, will that be enough?
I am using both video outputs on the back of the mini, VGA and HDMI. Thes VGA is running to a projector and the HDMI is running to a computer monitor. I am also running Bootcamp WINDOWS 7. When I power up the Mac, the computer monitor goes to sleep and defaults to the projector as the main monitor. If I power on the projector first, before powering the computer on and then power the MAC on, it recongnizes the computer monitor as the default monitor. Why can't the MAC mini recognize the computer monitor(HDMI) as the default when both video outputs are connected?

I recently have gotten into video, such as downloading .mkv files from Vuze, and .mov and .avi files from various other places. Now that I will be purchasing a Mac mini I hope to watch movies from the iTunes Store. One of the things I hated about my Power Mac G4 500 is that it's slow processor could only play about 45 percent of the videos I had. The rest of the videos I tried either the audio and video would either out of sync, just sputter along, or refuse to play at all. Will the 2.0Ghz processor of the new Mac minis be sufficient for video, or do I need to go with the 2.26 Ghz processor offered in the "build-to-order" option?
Can the new mini's with the new video cards run final cut pro? I am not a video editor but do some small projects once in awhile. I would max out the mini at 4GB of ram running (2) 24" monitors.
I received my new mac mini last week and installed a few things on it over the weekend so that I can run it as an HTPC. Works great but I am having one issue and that is with the video signal. I have the mac mini connected to my Samsung 720p LCD TV with VGA using Apple's miniport to vga adaptor.
When the TV is already turned on and I start the mini or bring the mini out of sleep then everything works OK. However if the TV is off and I start the mini or bring it out of sleep and then turn on the TV, I get a "no video signal" message.
I have a Dell quad core PC with adobe elements but was considering a mac mini with maybe final cut express. Is it worth the spend? I fancy a mac but my dell is a decent machine. Do you think I would appreciate the mac/final cut for home movies?
