External USB Maxtor One-Touch 3 suddenly fails to mount on MacBook Pro:

External USB HD suddenly fails to mount on MacBook Pro:
My One Touch III 600GB drive, external power supply, suddenly will not mount and is not recognized by the system profiler or Disk Utility, however, drive, connected USB, appears under windows XP.
1. Power cable and usb cable working.
2. Using external AC adapter(not relying on USB power).
3. Other USB devices, mice, flash drives work on both USB ports.
4. Drive works on Windows, folders and data integrity ok.
5. Drive format is NTFS.
6. No Maxtor software installed.
7. No humming or strange noises emanating from drive.
8. No problem to January 14, 2008,
9. Mac OS 10.4.10 updates last downloaded and installed Jan 20, 2008.
10.1 blip of the light on "The One Touch Button", then light turns solid white.
Questions:
1. Does Apple set sleep or lock switch for devices (drives)?
2. If so, can it be reset manually?
3. Does Apple have configuration profile for devices, like a registry key?
4. If so, where is it located?
Configuration:
Dual 2 GHz MacBook Pro 15”
2 GB DDR SDRAM
OSX 10.4.10
2 USB Ports Left and Right

NOTE: This Update is required when using a OneTouch Drive as a bootable device. Seagate suggests that you dismount and disconnect your FireWire Drive before continuing.
Users have identified issues when connecting OneTouch External Drives to FireWire Ports on their Mac G4 and/or G5 computers. These Problems range from system hangs, kernel panics to slow data transfer rates. The cause of these problems has been traced back to the FireWire Driver. Seagate has resolved these problems through updated FireWire Drivers.
I am using USB and not trying to use drive as a boot device.

Mac Pro power off suddenly when remove power cord

hi, i've just got my new apple mac pro from the store fresh for 2 months, and my battery cycles have been only 13.
just now when i accidently uplug my powercord, it shut downs instantly, i'm so worried about this, i'm having a final exam in 2 weeks, and if it keeps happened like this i'm gonna be so unhappy.
is this a serious problem, anyone getting this ?
can i change it to new one at the store ?
I'm in Melbourne, Australia

That certainly isn't what should happen — the machine should instantaneously and seamlessly switch over to battery power when the MagSafe plug is disconnected, unless the battery is drained or dead. What was the state of your battery when this happened?
Please test again, with your battery fully or partially charged, the machine running, and no documents open. Disconnect the MagSafe connector properly by holding the plug and tipping it downward until the electrical contact is broken. Does the machine shut down or keep running? Post back with results.

Selective USB power while Mac Pro sleeps

My Mac Pro seems to power all USB ports during sleep. I would like to selectively power some ports and not others. For example, I have a utility USB light on the back of the MAC Pro and a CwLinux LCD screen on the front which I would like to see turn off whenever the Mac sleeps (The USB power controller gets hot if these stay on for long periods without airflow).
Any thing in Leopard that would control this behavior?
Thanks!

There is no provided mechanism to selectively control power to the USB or Firewire ports. Normally USB ports shut off when the computer is asleep unless you connect a device the prevents the port from shutting down, which you obviously have. You will just need to get used to disconnecting them when not in use if they don't have power switches.

Another 7300 GT failed in model identifier Mac Pro 2.1 early 2008

I am getting horizontal artifacts on any and all displays I try using with this Mac Pro. The artifacts look like red - (dashes).
I have reseated the ram, zapped the PRAM, unplugged the system for 2 hours, removed and reseated the Nvidia 7300 GT video card, reset the button on the motherboard, removed all hard drives and booted to the original Mac Pro install DVD. Nothing makes a difference. Always red dashes either over the Apple logo or across the entire screen.
While booted to the DVD, I have to be in SAFE mode (shift key down during bootup) to even get to the desktop, then there are red dashes all across the entire screen.
I ran the extended hardware test and no problems found.
The capacitors do not appear to be swollen either.
Any suggestions?

You probably read how that 10.10.2 security update changed the build number of the OS, how Apple is still using really old Nvidia driver from 10.8.2.
So called "Security Update 2015-002" from today will purposely break nVidia drivers! ( 1 2 3)

Mixing ATI and Nvidia in older versions of Windows was a no-no.
With 10.10 I would ditch the 2600XT, it is doing nothing for you except taking up a slot.
you really just could ask and no need to drag 60 lbs and have someone else put a GPU in and attach the 6-pin aux power.

Install failed on early 2008 Mac Pro

I've put off installing 10.8 on my old (but not that old) Mac Pro. Bought a new hard drive, partitioned it, installed 10.6 on it, installed 10.6.8 on it, and then bought and downloaded Mountain Lion. The install seems to work, but then, rebooting, i get the gray screen, never the Apple logo, and after ten minutes or so the computer boots into my old 10.6.8. I guess I can try reinstalling, but damned if I can find the .pkg. I hate to have to redownload 4.4 GB. Any advice appreciated.

Reboot and hold down the option key. You should be taken to the boot manager which lists all bootable drives attached. If the 10.8 install worked, you should see three drives, the 10.6 drive, the 10.8 drive, and the 10.8 Recovery HD.
If you don't see the 10.8 partition, then it didn't install correctly. It may be trying to boot the 10.8 partition, but can't and eventually goes to the 10.6 partition.
While booted, go to System Preferences, Startup Disk, and select the desired startup disk.

Putting the power of Mac Pro to the G4

I've recently upgraded my Intel Mac Pro by removing the two 512k DIMMs and replacing them with two 2g DIMMS, making it 4g.
My non-Intel 1g G4 is now appearing a bit weak and I wondered if I could transfer the two 512k DIMMS that orignally came with the Mac Pro to the G4 to make it a 2g G4.
(I've had a search but cannot find anyone asking this question, so it might be a really BAD idea...so I do apologise.)

Mag safe power cord Mac air 11"

This is really frustading - I bought a MacBook air just less then year ago and I can even charge it anymore. The mag safe charger starter to work intermittently and wanted to find out what it was causing this so I started to scout the Apple support. One of official solution apple provides deals with line noise. So I did what they suggest, which is to remove charger from wall and wait 30 seconds or so and plug it back in. This was working for a time but now stoped working altogether. Do you think I need a new cord? I mean it's practically still brand new. Can a charger fry so soon? And should apple replace? I was in an apple store recently ( in Naperville Illinois) and the genius told me they didn't even look at power cords. Please can someone help me guide to what is the best approach to this issue ?

< Edited by Host >

All we can do is suggest you take it to an Apple retailer. If the computer is in warranty and should the charger need replacing, then it should be covered under the warranty.

HT3728 my airport express unit has suddenly failed No power. I have checked the fuse. Is it useless now?

I have had this airport express for a couple of years and it suddenly just failed.
The unit is not showing power is reaching it.
No light
I have checked the fuse
Is there anything i can do or is it useless now?

Try a Factory Default Reset as follows:
Pull the Express from the power jack
Wait a minute
Hold in the reset button first, and continue to hold it in for 7-8 additional seconds while you simultaneously plug the Express back in to power
Release the reset button after the hold period and see if the Express will restart in 40-45 seconds to a slow, blinking amber light
If you try this a few times and the Express will still not power up, there is an internal electrical problem with the Express and it will need to be replaced.
If you want to attempt a real longshot, carefully saw open the case of the Express along the center seam to open up the device and look for something obvious like a connector or wire that has come loose.

Ac adapter / power cords, mac mini

where my ac cord goes into my power adapter, it seems loose, it works fine as long as it dosent move but once it does my mac mini will lose power. is it just mine and is it worth purchasing a new one.

Welcome to Apple Discussions!
I can't say that I have the same experience with the power supplies and cables for the minis I own and look after, so I don't think yours is a common experience - particularly not if it is possible to cause power loss simply by moving or jiggling the cable.
Depending on how old your mini is, you may be able to get the supply replaced under warranty, but I would say that given the potential damage you can do to the hard drive (corruption of the catalog or data, not physical damage) by interrupting power while the drive is active, it would not only be worthwhile, but also rather wise, to go ahead and buy a new power supply if you can't get one under warranty for free.

IMove all of a sudden will not open on Mac Pro

iMovie will not run on my MacPro. It has in the past. The window I get says that it requires a graphics card that is compatible with Quartz Extreme. One or more of your graphics cards does not support Quartz Extreme. What? It runs fine on my Mac Book Pro and even my old imac. Any ideas? I am stumped. I have not changed my graphics cards in my MacPro so why won't it run? Any help will be appreciated.
Thanks,
Tom

Having the same problem with it either not opening, freezing on opening, or opening and then half of the clips are missing, won't display, projects are missing, etc. Tried all of the fixes listed here to no avail. I've been searching all over the iMovie 08 forum and this problem is posted in several different threads. It appears to be a growing problem for users of 10.5.3. One post had you throw out a preference file, I tried that too but nothing in any of these posts is working. Any other ideas?

Tip - Mac Pro fails to boot up, no chime.

I have a Mac Pro (Intel, 2008). Within the last 6 months, a situation with the Mac Pro has occurred twice.
While asleep, or shut down, I press the Power button to start up the Mac Pro leading to the following events:
the graphics card fan runs at full speed.
the LED indicators on the RAM cards all light up red.
the HDD's begin to spin.
the startup chime does *not* sound.
the screen does *not* turn on.
the fan does *not* slow down.
several seconds after pressing the Power button to start up the Mac Pro, it shuts itself down.
it is not possible to reset the PRAM. (the startup sequence does not proceed far enough to allow this to happen.)
resetting the system via the reset button on the mother board does not affect the situation.
replacing the PRAM battery does not necessarily correct the situation.
removing every HDD, RAM card, PCI card and cable does not correct the situation.
this is what has worked for me.
assuming that the Mac Pro is not powered up:
unplug the power cable.
press the Power button for 5 seconds to drain any residual power from the system.
let the Mac Pro sit idle for 12 to 24 hours. (10 minutes simply doesn't do it!)
plug the power cable in.
press the Power button to boot up the Mac Pro.
removing the HDDs, RAM cards, PCI cards and cables may or may not affect your situation.
the first time my Mac Pro booted after this procedure, only 4GB of RAM was recognised by the system. I shut down the Mac, removed and re-inserted the RAM cards and booted the Mac up again. the Mac then recognised all of my RAM (20GB).
hopefully, we'll see a new generation of the Mac Pro this year with *both* firewire and thunderbolt.
cheers all.

Hi Greg! Yeah good tips. I'd like to add a few other tips that worked for a few of us. I have a 2009 nehalem MPro, 16 cores, 4 used internal bays, 5870 (added in 2011), replaced main boards, power supply, memory and CPU modules under extended warranty. Several ATTO pcie sas cards (r380,h380) bla blah.
History:
Ok, we we moved the whole suite to new premises some months back and the transportation was safe and well and due to premises issue, the setup above Nd the disk arrays etc sat I. The packing for two weeks...
Issue:
Mac Pro would not power on some times.. Else it would power on and then after or during startup would shutdown.
Cure:
Did most of the steps you described and
1) pulled all the disks from bays 1-4, pulled all the pci hba card including the ati 5870, pulled the two DVD player units and lastly, the CPUs and memory module unit.
2) cleaned all contacts with cans of clean compressed air of all the above
3) then proceeded to replace each component then powering up the Mac Pro and make sure the startup chime occurrs, then power the Mac Pro off.
4) I started with the memory module with a single DIMM in the memory, finally replacing them finally with all of them repeating step 3. I did find a bnd memory dimm doing this. Don't worry if the Simms are not inthe most efficient slots.. Fix this later.
5) replace the GPU card (in my case ati 5870) strap Nd shutdown
6) this time hold the power button in for at least 20 seconds and reset the SMC.. Wait for the squeal!,
7) then do one of the disks or the disk set that you start from..
8) restart. .. Wait for it to settle. Power off
9) plug in the mainscreen display and restart .. By now it all should be ok.
10) power off again. Power up again with key board and restart and then shutdown
11) add/insert each pcie Hba power up and. Reset the SMC AS IN STEP 6 and shutdown. Repeat for any other MAKE SURE THAT THE SPEED OF THE PCIE card matches the rating of the slot. so remaining hbas.
12) should be looking good by now.... So login and then shutdown
13) and remainder of the internal disks , power up and access file systems.
14) should u get the memory manager appear at startup and recommend to re-organise the memory Simms, then print the report or use your iPhone to record the display, shutdown and move the dimms s it requests.
15) lastly serially plug in other peripherals and see hat they can be accesses.
Summary: worth the effort NDS time. Macpro has been solid ever since.

ATI R9 290x - Mac Pro 2009 4,1

Hey all. I just wanted to share my experience with video card upgrading. I have searched tireless on all forums to find solid answers and figure out what the **** I can put in my computer.
I ended up buying an ATI Sapphire R9 290x off eBay for like $225. The real reason is for playing games in bootcamp running Windows 8.1. Otherwise, I really didn't need to buy a new card running in Apple's OS X for work.
My biggest concerns were 1) will the video card even work and 2) do I need another power supply for it.
I don't care about EFI flashing, I really don't see a need for it. I have my old ATI 4870 if there were a reason I need to use that. The selection for non EFI cards are far better and far cheaper.
Back on point. Initially I had issues with the 290x, nothing working with my current setup. I also purchased a 6pin to 8pin PCIe cable for the card's power.
I use the system for Protools HD. Besides the video card I have an AVID Native HD PCIe card and a 4-port USB3.0 PCIe card. I also use each hard drive bay. Mac OS, Windows 8.1, an separate spare drive, and one for Time Machine backups.
After several attempts, I took out the PCIe cards and all the hard drives, except for the Windows drive, and it booted up.
To make a long story short, I had to install OS X 10.10 on my main OS X drive for the card to boot up with everything else connected. I did a clean install because of some conflicts between a generic USB3 kext and OS X 10.10.
So everything was cool. Running Protools in OS X 10.10, no problems. Running Battlefield 4 in Windows 8.1 seemed to be going fine at first, but I had a couple of shut downs after about 30-60 minutes of play. I added a separate power supply (650w) and that seemed to take care of the sudden shutdowns. Likely the Mac Pro power supply is just a hair short of power when it starts to stress out on more intense stuff. Also for those who don't know, to run the power supply separate, you have to do the power clip trick (google it). It might that if I wasn't running the other two cards and other hard drives, I might not need another power supply, so I would try without it first if that's the case for anyone upgrading.
***** because I have to keep the case open for now until I find a better solution to the power cable, but at the end of the day, running Battlefield 4 with Ultra settings, is worth the hassle this was.
Hopes this helps anyone else.

Thank you for daring to bravely forge ahead into the unknown compatibility mire of graphics card land. I was hesitant to think beyond the different that Apple intended for the Mac Pro and try out the 290, but finding your post and another on Barefeats has assuaged my doubts. We will soon be replacing our non-approved 6870 1GB with the non-approved power hungry beast that is the 4GB 290.
If you're interested in testing your soldering skills, I found a site that generously provided details on how to solder a relay between one of the SATA power plugs in the drive bay to the green and black wires on the motherboard connection of the external power supply. This way the second power supply turns on and off with the Mac's power supply, so there is no need to switch it off and on manually.
Soon our aging 4.1 will get its much needed pacemaker and not have to wheeze through increasingly graphics hungry games like Star Citizen and Elite Dangerous.
Keep MacIn'
