Mac Mini blinking rapidly - Mid 2007 1,83 Ghz C2D

Last night I left my Mini running, as usual. This morning something had happened; the white diode was blinking quite rapidly, and it was a constant blinking with no particular pattern. I tried unplugging everything, and then repowering but with no luck. What happens is that I hear the CD-rom, and then 1-2 seconds later it starts blinking. I do not hear the startup chime. The display is also black and does never show any sign of life.
There have been no symptoms what so ever prior to this, it has been working beautifully. Does anyone have any clue on what might be wrong?

I have now tried quite a lot, but with no results. The HDD is fine, I tried putting that in an external cabinet and i was working perfectly.
Then I tried replacing the RAM, which didn't help either. My conclusion is that the logic board is probably the problem. The Mini, sadly, has now been replaced ny a new one...

The new Thunderbolt technology in Mac mini is phenomenally fast. It features two 10-Gbps channels for data transfer. That’s up to 12 times faster than FireWire 800 and up to 20 times faster than USB 2.0. But beyond speed, Thunderbolt technology gives you unprecedented expansion capabilities. You can daisy-chain as many as six Thunderbolt peripherals, including the new Apple Thunderbolt Display. And since Thunderbolt is based on DisplayPort technology, your Mini DisplayPort devices plug right in, too.

Try these in order testing your system after each to see if it's back to normal:
1. a. Resetting your Mac's PRAM and NVRAM
    b. Intel-based Macs: Resetting the System Management Controller (SMC)
2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
     Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
     COMMAND and R keys until the Utilities menu screen appears. Alternatively, restart the
     computer and after the chime press and hold down the OPTION key until the boot manager
     screen appears. Select the Recovery HD and click on the downward pointing arrow button.
3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
4. Reinstall Yosemite: Reboot from the Recovery HD. Select Reinstall OS X from the Utilities menu, and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
            because it is three times faster than wireless.
5. Reinstall Yosemite from Scratch:
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.

Note: You will need an active Internet connection. I suggest using Ethernet if possible
            because it is three times faster than wireless.

Intel Mac Mini Core Duo Midi USB Issues

Is anyone else having issues getting Midi devices to work with the Intel Mac Mini's? I have several Midi devices that are't working correctly event though I have installed the newest drivers.
Currently I am having issues with a M-Audio Midisport 2x2 USB adapter. I loaded the newest drivers (ver 3.2.2) which are supposed to be universal binary to support the Intel Macs. When I connect the Midisport 2x2 to the Mac Mini I can not get it to receive Midi Output from the Mac.
When I look in the Midi control pannel I can see that the Midisport has been installed, but all options to select it are greyed out. Also when I try to select it as the input or output there is NO option to select the Midisport from the pull down menu. It only shows the "Built-in Midi" as and option.
The Midisport works fine on other non-Intel Macs. Please advise.
Thanks!
Mac Mini Intel Duo Core 1.66Ghz Mac OS X (10.4.7)

It seems like the mini is doing alright so far. I think maybe the full erase solved whatever issue it was having. I also got my Core Duo Mini yesterday in the mail and it's performing like a champ. Definitely a nice machine.
I'll close my question for now, since the Core Solo Mini seems alright. But, as a warning don't get on Front Row's bad side. I tried force quitting it because it was taking too long to load the videos folder and then tried shutting down from a terminal and ended up having to turn the machine off.

New Mac Mini Lion Server (mid 2011) and memory type

Hi,
I found an unclear advice about memory upgrade.
The manuals says
"Memory modules for your Mac mini must meet the following specifications:
-Small Outline Dual Inline Memory Module (SO-DIMM) format
-1333 MHz, PC3-10600E, DDR3 compliant (also called DDR3 1333)
-Unbuffered and unregistered"
I opened the box and found inside a Samsung chip labelled "... PC3-10600S-11-B2"
Is the PC3-10600E type the same as PC3-10600S?

Now resolved....... No further comment

Mac mini (intel) vs iMac G5 1.8 GHz

Hi all,
I'm thinking of changing my Apple Computer from a 20" iMac G5 1.8 GHz 1.2 GB RAM to a Mac mini Core Duo 1.66 GHz with 2 GB of RAM with a Apple 23" Cinema Display.
Does someone know if that is a "downgrade" in performance?
Thanks for your answers.
Stefan
20" iMac G5 1.8 Ghz Mac OS X (10.4.6)

Looking at your list *I think* you should be, for the most part, better off. You list a large amount of Apple applications what are all Universal binaries. Windows will work under Boot Camp or Parallels. Microsoft Office 2004, from all reports, works extremely well even though it's not Universal. The rest being utilities don't really matter much.
The only stand out is Photoshop Elements. This will probably go down in performance although it depends on how much you're looking at using it will make this more or less important.
One thing you will definitely go back in is graphics performance although, from you list I don't think it's going to matter much, if at all.

WIndows Vista Home Premiun 64Bits + MacBook Pro 15" Mid 2007 ( 2.4 Ghz )

Hi all,
i have a MacBook pro, ( MacBookPro3,1 ) with bootrom version MBP31.0070.B07. It is the Mid 2007 model, with 4 GB Ram. I want to install Windows for gaming purposes and i was wondering, since the documentation in the Boot Camp Support seems to be mixed, Could i install Windows Vista Home Premium 64Bits OEM, or do i need to install the 32 Bit version ? the documentation seem to suggest that the boot camp 2.1 download will offer supoort for Vista 64bits. Please help me decide what best to do here.
Thanks in advance,
Luis R. Rojas

You need 64-bit if you want to use more than 2GB RAM.

I have a mid-2007 2.0 ghz MacBook, is Lion worth the upgrade

I currently have a mid-2007 MacBook 2.0 Core 2 Duo with 2.5 GB of RAM. Is Lion worth the upgrade and will it run well on my machine? Thanks!

im running lion on a 2.4ghz macbook pro with 2gb of ram from the same era. It runs ok...not the best, but if you upgrade to a solid state drive. Then itd probably run pretty good

Larger disk for Mac Mini 4.1 (mid 2010)?

Hello,
Just wondering if there any issues that might preclude replacing my original 500 Gb internal hard drive with, say, a 1 Tb drive?
Thanks.

That is fine. The only restriction is the the height of the drive has to be 9.5 cm or less.

IMac mid 2007, 2.4 Ghz, 800 MHz... Grey screen only, running OS 10.5.8. Tried reinstalling, restoring, and resetting but to no avail. Possible to install OS 10.6 and get it to boot?

Try to boot and only getGrey screen, sometimes with the globe f
Asking, sometimes not.
I am running OS 10.5.8. Tried reinstalling, restoring, and resetting both with installation disc and without, but to no avail.
I recently upgraded from 1GB memory to 4 GB. It ran great for a couple of weeks, when I eventually powered it off, it would not come back. With installation disc, I did get to the utilities and tried repair and even reinstall original OS (several updates down from 10.5.8). At one point, I was able to restore a previous session, but it only lasted for about 3 days until I powered it off again, then back to square 1. I have verified the Macintosh HD disc and repaired it, I have reset everything I can find that might need resetting... Still nothing.
SO, is it toast, or is it possible to install OS 10.6 and get it to boot?

Erase the drive then install OS X:
Drive Partition and Format
1. Boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
If you are preparing an external or a non-startup drive, then open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Apply button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
If this doesn't work then the drive is probably bad or some of the new RAM you installed is marginally defective.

That panic was not caused by third-party software. If the problem is recurrent, the possibilities are:
A stale or corrupt kernel cache
A damaged OS X installation
A fault in a peripheral device, if any
Corrupt non-volatile memory (NVRAM)
An internal hardware fault (including incompatible memory)
An obscure bug in OS X
You may already have ruled out some of these.
Rule out #1 by booting in safe mode and then rebooting as usual. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a Fusion Drive or a software RAID, you can’t do this. Post for further instructions.
You can rule out #2 and #3 by reinstalling the OS and testing with non-essential peripherals disconnected and aftermarket expansion cards removed, if applicable. Sometimes a clean reinstallation may solve a problem that isn't solved by reinstalling in place.
Corrupt NVRAM, which rarely causes panics, can be ruled out by resetting it.
If your model has user-replaceable memory, and you've upgraded the memory modules, reinstall the original memory and see whether there's any improvement. Be careful not to touch the gold contacts. Clean them with a mild solvent such as rubbing alcohol. Aftermarket memory must exactly match the technical specifications of the machine.
Apple Diagnostics or the Apple Hardware Test, though generally unreliable, will sometimes detect a fault. A negative test can't be depended on. Run the extended version of the test, if applicable.
In the category of obscure bugs, reports suggest that FileVault may trigger kernel traps under some unknown conditions. Most, though not all, of these reports seem to involve booting from an aftermarket SSD. If those conditions apply to you, try deactivating FileVault.
Connecting more than one display is another reported trigger for OS X bugs.
If your system is not fully up to date, running Software Update might get you a bug fix.
In rare cases, a malformed network packet from a defective router or other network device can cause panics. Such packets could also be sent deliberately by a skillful attacker. This possibility is something to consider if you run a public server that might be the target of such an attack.
Otherwise, make a "Genius" appointment at an Apple Store to have the machine tested. You may have to leave it there for several days. There isn't much point in doing this unless you can reproduce the panic, or if you can't, it happens often enough that it's likely to be repeated at the store. Otherwise you may be told that nothing is wrong.
Print the first page of the panic report and bring it with you.

Mac Mini (late 2012) vs. iMac (mid 2007)

I use my computer primarily for video conversion, internet, iTunes, iPhoto, iMovie (occassionaly...too slow), iWork, Office, various other things but NO Final Cut video editing and intense graphics work.
I've wanted to get a new Mac for quite sometime. I have an abundance of monitors, mainly HD, just laying around collecting dust, one on a Windows () 8 computer, figured I might just get a Mini.
I have an opportunity to upgrade from a:
24" iMac 7,1 (mid 2007)
2.4 GHz Intel 2 Core Duo
4 GB Memory
ATI Radeon HD 2600
to a:
Mac Mini MD387LL/A (late 2012)
2.5 GHz Intel Core i5
8 GB Memory
Intel HD Graphics 4000
Questions:
1. % wise, how much faster would it take to convert a video of the same format and length? Significantly?
2. I use AirParrot to send internet video to my Apple TV, tried looking for it (remember seeing it somewhere), can I see my screen or AirPlay it to AppleTV without having to use a HDMI or AirParrot application.
3. Will I really see a TREMENDOUS amount of performance from the newer Mini in comparision to my old iMac?
I've read reviews online and have amazing read arguments for and against to the point that my gut is going crazy. Are the benchmarks between the i5 and Core Duo significantly going to reduce my work load.
Please provide some feedback as I truly appreciate it.
THANKS!

I have a Mac mini (Mid 2011). It has become slow in some ways even though I have 8 GB 1333 MHz DDR3 memory and almost 250GB of free storage. I recently installed Yosemite 10.10.1 (14B25) but I had noticed the slow down prior to that. Notably, videos no longer run smoothly. Instead, there are brief pauses in playback. I initially thought it was a problem with streaming videos but then found the same problem playing TV shows and movies downloaded from the iTunes store.
There are now also lags for starting up certain programs and many programs seems sluggish once open. Not sure what could have caused the slow down since I don't even use the computer at issue very much and haven't recently installed any new software. No programs launch with log-in and all notifications are turned off. Any ideas? If there's a problem specifically related to video, I'd be interested in hearing that too. I use a Samsung monitor but it and everything else about my computer used to work perfectly and videos ran smoothly until fairly recently.

Mac Mini (Mid-2011 Core i7) Slow after Yosemite Upgrade

I've searched the other "slow after Yosemite upgrade" threads but those seem to relate to Core Duo 2 machines with less RAM. I have a Core i7 MM w/ 8GB of RAM, after the Yosemite upgrade it constantly lags, I can barely type on it these days because the text lags so badly. It's unusable to say the least. Is there anything I can do to speed it up? There must be a reason why the performance is so bad.
Problem description:
Slow after Yosemite upgrade.
