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?
View 11 RepliesI 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 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
Is there a way to diagnose this?

I am on the latest version of Mavericks, with all updates installed. My 2009 MacBook Pro freezes a little bit after airport turns on. This would appear to also carry over to when the computer is starting up because when I am able to turn and keep airport off the computer never freezes during startup. Less than 3 moths ago I had Bly airport card replaced so I doubt that the problem is with the hardware.
Except for this one issue, my computer is running perfectly fine. The problem has persisted with a clean reinstall of OS Mavericks. It'd be happy to rely on an Ethernet cable, but that won't be possible in the near future, at least not without lots of wires running across the floor.

View 2 Replies View RelatedI've been digging around for a couple weeks now for information on what may be happening to my MBP. I've tried numerous solutions, but don't seem to be able to get the computer to STAY ON. Here's my story:
A couple weeks ago, my room mate was using the computer. She closed it to put it to sleep, and left it on my bed. When I went to turn it on, the screen was completely black and the indicator light on the open button was a steady grey. The computer was so hot it was painful to the touch. I unplugged it, hard powered it off, and let it sit, thinking it was an overheating issue.
Since then, the damn thing won't stay on. Initially, it would intermittently just shut off. When that happened, sometimes I could boot it back up, and other times it would sound like something was whirring in the background, but the screen stayed black and the indicator light stayed solid grey. I installed SMCFan and istat to monitor/control the temp and fans.
I noticed somewhere along the way that there seemed to be some connection between episodes of shutting down and the power cord (as in, if it was jostled, the computer shut off)(I should note that my battery is at about 15% health with a full charge). Then, that power cord died (no green/amber indicator light and no connection detected). So I bought a new cable, and set about trying to fix the problem again.
Next phase, it seemed that if I moved the computer, it shut down. So I did some of the recommended fixes. I deleted the power management plist, I changed the settings to never put the computer or the display to sleep, and I turned off the quick-motion sensor that stops the hard drive. I also reset the SMC settings.
This seemed to improve the situation a little bit, insofar as now instead of getting a shut down, I am now getting complete reboots that only *sometimes* lead to the blank screen and steady grey indicator light. This does happen more frequently if I move the computer, but it can also happen if I simply leave it to run. In fact, if I send the computer into sleep-mode, and close the lid, I'm practically guaranteed a reboot.
So, then I reset the PRAM and did the hard-reboot (ctrl+opt+power) and reset the PRAM again. I am currently running Rember to test the RAM, but I'm not sure what to look out for when it finishes, or what I should do about it.
My old Mini is in the next room to the wireless DSL modem. It gets one to three max bars, usually two, and it's just through one interior wall. I don't want to spend a bunch of money, I just want to get a little better reception in the next room. I have seen USB wifi antennas advertised. Would that do anything for me? My iBook G4 in the same spot gets full reception no problem.
View 5 Replies View RelatedI have MacMini and the display signal turns off intermittently (i.e. not just sleeping).
The display is via a VGA connection to a Philips monitor (although I've tried with an Acer VGA monitor too and get the same problem).
The only way to fix it seems to be to turn the Mac off and on again.
I feel pretty disappointed. I've used Apple Macs since having a Mac Plus 20 years ago and have always recommended people to use them because "you just plug things in and they work"...
But this is simply rubbish. It's practically useless. should I just try to get my money back under the "not fit for purpose" clause in the sale of goods act.

I received a refurbished mini this morning, 2.26 160gb. After setting it up I am noticing a constant clicking noise. I do understand that hard drives aren't silent, but this is a constant sound approx. every 20 seconds. This happens even when the mini is idle.
So, I searched around for some information. One suggestion was disk utility, make sure SMART status is verified (it is). It's a fujitsu 160gb.
The little progress spinner thing below the apple just spins and spins. The computer said that several apps stopped responding and had to quit after falling asleep watching a movie in VLC, which had error logs that had frozen on the screen as well saying, "Computer too slow?" from dropped frames apparently. Not normal. Also, yesterday, when waking it up from the display shutting down, the whole screen was gray and smeared looking. There was nothing recognizable at all on the screen, and I hit the power button quickly for it to sleep, and back again and it worked fine for the rest of the day. Its a 1.66 Core Duo Mac mini w/ 2gb of RAM.

Is it possible to change core 2 duo in mac mini 270 to i7 or i5?
Info:Mac mini, Mac OS X (10.6.8)
are the early models of Mac Mini Intel Core 2 Duo made in 2006 and 2007 (for instance, Core Duo 1.66 GHz, or 1.83 GHz, or 2.0 GHz, with 2GB RAM) compatible with Mac OSX 10.4.11 Tiger?
Can I run Mac OSX Classic environment on a Mac Mini Core 2 made in 2007?
I recently moved to a MacMini Server Quad i7 to give my studio a boost. From what I was reading it was giving other post-audio pro's a **** of a boost in performance for obvious reasons.Been pretty good the last couple of weeks, but today, during a large session, it started choking.I opened up the Activity Monitor and, aside from obviously needing more RAM, my CPU was going pretty hard. An odd thing I noticed though: In both the CPU tab, and the Dock "Show CPU Usage" only CPU/Bar shows up. On my previous Mini (a 2.66 Core 2 Duo) 2 CPUs/Bars are present. This seems very strange to me that a Quad core shows up as 1, but am I wrong in my assumption? It seems to get VERY taxed vs. my old system, and given the fact that they have the same amount of RAM this seems very wrong to me.

I have a Mac Mini with 2GB of RAM. I am New to Parallels. I am running Parallels 4.0 How many CPU's should I have configured for a core 2 Duo Mac Mini? It is currently set to 1. Should I configuer it as 2? If so, why can't I change the CPU configuration once the VM is setup? Do I need to Create a New VM?
View 1 Replies View RelatedIn the interest of energy savings, I think it would be great to be able to use switchable graphics on my Intel Core i7 Mac mini. Since the i7 chipset has the Intel HD3000 GPU onboard, this should be possible, but it would probably require some sort of hack or modification to the EFI. I've searched around online but only find mention of using both Intel HD3000 and discrete graphics with a Hackintosh.

I am looking to get another mac to do some basic video editing and encoding. All the editing is going to be done in the mpeg4 format and once the video has been edited I am going to encode the video into H.264. My question is which will be better A Power Mac Dual 1.8Ghz G5 or a Mac Mini Core 2 Duo?
I am looking for stable set up that can handle encoding video for a few hours at a time. I am leaning towards the Power Mac Dual G5 because of how much more cooling it has however that said a Mac Mini with a Core 2 Duo running at 1.66 Ghz would also probabley work well.
I would like to know if the mac mini 2.0GHz Intel Core 2 Duo (bought at U.K.) has a characteristic in the PSU called PFC and if it is active.

I am using a Mac Mini with a Realtek USB wireless dongle to connect to the internet. The software and drivers appear connected perfectly and i see the wireless utility and I can access my wireless network, which says signal strength 100%. I connect to it and it accepts the wireless key. Says connected. Then after a few seconds the connection is lost and it says 'Disconnected'. A few seconds later it connects then disconnects and this continues indefinitely but Safari never allows me to access any webpages.

After moving I setup the Mini, but got nothing from the monitor. Reset PRAM & PMU, nothing. CPU chimes, etc.work, but the only thing I get from the monitor is a yellow square with a brief message indicating there's no signal.
It's a Mini, 2 MB RAM, Core 2, OSX10.5.x, it's less than a year old. The CPU appears to be OK. Monitor is getting power.
I have an Intel Mac mini (purchased in 2005 or 2006) with a fresh install of OS X Leopard on it. I recently changed the Startup Disk in the OS X system preferences to be the CD/DVD drive, and everything has gone downhill since there.
I inserted a CD and attempted to boot from it right after changing this setting. I noticed the CD drive spun up the disk, but after waiting several seconds a black screen appeared, saying "No bootable device — insert boot disk and press any key".
There were two problems here: first, the CD never ejected from the computer, and second, there was no response to any key press.
After restarting and shutting down a few times I got the Mac to spit out the CD somehow. I restarted, inserted the same OS X Leopard disk used to install the operating system earlier that day, and got the same "No bootable device" error.
In a few weeks time I'm getting my Mac Mini upgraded to 2GB memory for Snow Leopard when it comes out. My Mac Mini is a 2006 Intel Core Solo model, and in September I'll be wanting to buy Snow Leopard but I want to be 100% sure that my Mac Mini will be able to install Snow Leopard since its DVD media. I know I can't burn DVDs with this Mac Mini but, although may seem like a stupid question will I be able to install Snow Leopard with it being DVD media.

I see the numbers of everything from Core 2 Duo, to the slightly faster and cooler Core i3, to the supposedly faster core i5s and i7s. The benchmarks go up accordingly, but I found this does not always equate in a faster experience on most tasks.
Here's my experience so far on processor upgrade:
In one computer trade school re-certification class I am in, we are working with Windows Server 2003 on a Quad Xeon platform and it's incredibly slow.
But in a previous class we had the previous generation server edition on older Xeons, and while not fast, it was much better. On paper the newer multi-core Xeons should have made a difference, but could 2003 server software be that much more bloated than the previous Windows server edition that it would stall like that and make us wish we had the older setup?
I am going to try out the Adobe CS lab and put the new high end Dells to the test there and see if they work better than when we had an older CS version on older Xeon equipped Dells.
I don't know if this is something to do with Dell, or if Apple's increasing processor bumps/generations are going to similarly not make a difference in the speed things appear to go at, whether it's Adobe stuff, server stuff, or anything else that needs power.
I know somebody who plans on a Core 2 Duo, i5 or i7 MBP and I was wondering if the higher end processor is worth it in that case (iMovie being the main program of use).
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.

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.
