Mac Mini(Late 2014) - Tick Sound

Hello Apple User's. I just purchased a new Mac Mini late 2014 a month back. I had no problems initially after setting up my mac for the first time. I'm Currently working with Apple as a Technical Support Advisor in level 1. I was doing R&D on my mac and happened to corrupt the OS. Hence did IR and Re-installed the OS.I hear these tick noises only after re-installing OS. Hence I'm pretty sure the OS build which I got by default with mac was the best compatible OS. Now after doing IR I have 10.10.1 with a different build. I'm 100% sure it has to do with the build of my OS. Anyways I'm trying to find a solution for the same. Hence I would suggest all the Apple fans to keep an eye on this section.

Well I'm sorry for the late reply. But I'm back with a Solution for the "Tick Sounds" on the Mac's. After researching carefully, I happened to learn that , the Tick noise in SSD HD is because of the Head Parking of the pointer on the HD. Hence in order to get rid of the Tick sound, I would suggest all , to turn off/Disable the option "Put hard disk to sleep whenever possible" in Energy Saver section of System Preferences. Thus when the system is idling or in use (awake), you don't get to hear the Tick Sound's. Well after careful observation for almost a month now, I hardly get to hear the Tick Sound once in a day or so.
In Energy Saver "Put HD to sleep whenever possible" is more useful to portables like, MacBook Pro or MacBook Air , since it will consume less battery, and thus enhance the battery life but not for machines like iMac/Mac Mini.
Also some people have installed some 3rd party utilities like Hard Disk Advanced Power Management (HDAPM) to minimise the head parking or reduce the Tick Sound. I would personally not suggest to go for it, since it will change the default behaviour of the HD set by the manufacturer and may corrupt the HD and it may eventually fail. But if you would really like to give it a try, go for HD SPY utility in Mac Appstore , since Apple would have released the utility after taking due consideration in the Appstore.
And for tbirdvet, thank's for the response. I will have to read more about the mechanism on how the Fusion Drive work's and then take a call on it.
Nevertheless I would appreciate if anyone comes out with a different solution for the Tick Sounds from the HD.

  • HT201541 Mac mini Late 2014 Boot Camp Windows 7 sound issue

    Hi,
    I'm wondering if anyone can help me with my Mac mini (Late 2014) and Boot Camp (Windows 7). The problem I'm having is that there's no audio when I boot into Windows 7, though everything works fine under OS X. After installing Boot Camp and Windows, the audio worked perfectly up until yesterday, and now there's nothing. I've tried updating as well as uninstalling and reinstalling drivers, but this hasn't helped at all.
    When I open Volume Mixer and Playback Devices, the sliders show that audio is playing, but I hear nothing - either from the built-in speaker or when I headphones.
    The Device Status indicates that "This device is working properly" and that the drivers are up to date. Tthe following drivers are installed:
    dmk.sys
    HdAudio.sys
    ksthunk.sys
    portcls.sys
    SysFxUI.dll
    WMALFXGFXDSP.dll
    Has anyone else encountered this issue, or does anyone have any tips on how I might fix this?

    Is the volume Muted? The Mac has an Audio database of devices and volumes in NVRAM, so an SMC Reset or PRAM reset might help. Please see this link for appropriate keys Startup key combinations for Intel-based Macs - Apple Support.

  • Mountain Lion Won't Install on Mac Mini (Late 2014)

    My relatively new Mac Mini (Late 2014) is running Yosemite.
    I have purchased Mountain Lion in order to run a favoured version of sound editing software which is not compatible with either Yosemite or Mavericks.
    Attempts to download my purchased Mountain Lion from the App Store result in the following message "We could not complete your purchase. OSX Mountain Lion is not compatible with this computer".
    The 'Learn More' button takes me to the support article which states that Mountain Lion requires hardware of Mac Mini (Early 2009 or newer).
    In terms of software, it requires that Lion is already installed.
    My query is do I need to purchase Lion and install it before I can install Mountain Lion?
    My concern with this is that Lion itself requires Snow Leopard itself installed on the machine!
    Cheers,
    Lou.

    That is correct. Versions of OSX prior to Yosemite do not have the divers to support the 2104 Mac Mini.
    You may be able to run ML as a virtual machine (VM) using a VT app like the free VirualBox and paid parallels.
    However,you may not be able to get a copy of ML to install unless yo have another Mac that allows you to download the installer.

  • Mac Mini Late 2014 crashing nightly

    Several nights now my new mac mini (Late 2014), 10.10 has crashed and shutdown. It cold boots with power button press. Logs show it might be trouble with sleep, but posting this since long thread on these troubles with Yosemite is for Mac Mini 2012.
    Just got the machine on Friday. Used migration assistant to load settings and maps from Mavericks lap top. Crashed on both tries, but did set up an account. None of my user files transferred, did that manually. Hoping not to do a fresh install, but need to know if settings from Mavericks could cause a problem.
    Here is the log leading up to the crash. There are a few wake ups preceding this one (over an hour before) that didn't shutdown.

  • Install Windows 8.1 Pro on Mac Mini Late 2014

    I'm trying to install Bootcamp on my Mac Mini.  Windows reports that it cannot install or create a partition on the drive after formatting the BOOTCAMP partition as NTFS.
    This is my setup:
    1. Mac Mini Late 2014 with 2TB Fusion Drive.
    2. Windows 8.1 Pro x64 full version ISO downloaded from Microsoft Store.
    3. Sandisk Extreme Flash Drive (I have tried both 16GB and 64GB).
    4. Bootcamp partition = 500GB.
    5. Other USB devices plugged in: Corded USB Mouse and Apple Extended Keyboard (both of which are required to enter the serial number and navigate the installer window).
    6. No additional storage devices of any kind are connected aside from the internal Fusion drive and the installer drive.
    7. Booting from the EFI portion of the Bootcamp created Windows installer.
    I have read that I should try using a USB 2 flash drive rather than a USB 3 flash drive, so I will try that next.  I fail to understand how this could make any difference.
    If you have any other tips, please let me know.
    I have installed or helped other people install bootcamp many times over the course of the past 2 years.  Every single time it has caused endless headaches and literally weeks of wasted time.
    I have read endless posts on what is causing these problems.  I will consider summarising these for anyone else having the same problems.  Everyone has their theory so far about this Bootcamp nightmare, but so far there doesn't appear to be any one magic solution.
    Apple's inability to address the issue suggests that the problem may be with the Windows installer.  Perhaps Microsoft is deliberately causing this?
    I suspect the two most likely causes of these issues are the downloaded ISO or the Thumb Drive.
    If you have any better idea, please let me know.
    On another topic, how to I rename the NTFS partition back to BOOTCAMP?  All options to rename this partition are greyed out in Disk Utility...
    Cheers,
    Paul

    The FAT32/NTFS partition is usually not adequate for an EFI install. You can delete the BCA-created partition and create a Disk Utility partition which is formatted as Free Space. This will be split into an MSR and MSD. Fusion drives create problems, especially if the BC partition lies outside the traditional MBR 2TB boundary.
    Before you delete the BCA-created partition, please post the output of
    diskutil list
    diskutil cs list
    sudo gpt -vv -r show /dev/disk0
    sudo gpt -vv -r show /dev/disk1

    Windows installers up to W8.1 do not have USB3 drivers. These are installed after Windows is installed and BC drivers are in place.

    The requirements are pretty strict when installing Windows. Any deviations cause headaches and grief.
    I suspect the two most likely causes of these issues are the downloaded ISO or the Thumb Drive.
    The USB is usually the issue.
    On another topic, how to I rename the NTFS partition back to BOOTCAMP?  All options to rename this partition are greyed out in Disk Utility...
    After Windows is fully installed and BC drivers are in place, log into Windows, right click on it and rename it on the Windows side. It cannot be renamed on the OSX side with diskutil renameVolume. Here is an example sequence. You cannot rename volume during the installation process.

  • Install Bootcamp on Mac Mini late 2014 Yosemite Fails?

    Trying to install bootcamp with Win 8.1 pro on a Mac Mini (Late 2014) under Yosemite and get to the screen on Win 8 side which says 'Where do you want to install Windows?' and I choose the "Drive 0 Partition 4: BOOTCAMP" and the next button never becomes enabled.
    There is a message saying "Windows can't be installed on drive 0 partition 4" and an addition message box which says "Windows cannot be installed to this hard disk space. Windows must be installed to a partition formatted as NTFS".
    At this point I'm dead in the water -- cannot proceed.
    Formatting the drive doesnt work and just screws up the whole process.
    I've redone this quite a few times and end up in the same situation everytime.
    I also tried with Win7 install I had but that failed completely and it never really proceeded after rebooting from Mac side.
    Any ideas?
    Is bootcamp busted on Yosemite? I dont easily have another machine I can try it on.
    Is bootcamp busted on Mac Mini? Has anyone tried bootcamp on new late 2014 Mac Mini?
    Thanks
    James

    Hi Steve
    Its not a fusion drive. The full spec is
    2.6GHz Dual-Core Intel Core i5 (Turbo Boost up to 3.1GHz)
    16GB 1600MHz LPDDR3 SDRAM
    1TB Serial ATA Drive @ 5400 rpm
    Intel Iris Graphics
    I wanted the size of the drive large as I'm going to use it for just a small amount of Mac work and a very large amount of Windows work.
    I did actually click format during a number of the attempts I've tried. It generally formatted and left me no better advanced. Generally it would removed the word BOOTCAMP from the drive. I've even tried deleting the partition and reestablishing in -- that doesnt help either.
    My latest attempt has seen that the whole bootcamp partitioning structure is truly busted. When I go back to the Mac and enter bootcamp assistant it says I cannot do anything now and tells me the partitions cannot be changed. Now I'm really not in a great position.

  • Acer K272HUL and Mac Mini (Late 2014)

    Was wondering if anybody else has had issues with an Acer K272HUL monitor and a Mac Mini (Late 2014) when using HDMI as the cable connection?
    The issues I am having are as follows:
    The monitor won't come out of sleep mode when I use either the mouse of the keyboard. Instead I have to toggle the power on the monitor to re-detect the Mac's video source each time.
    The brightness buttons on the keyboard have no effect on the monitors brightness. I don't get the OSD like I do when I change the volume.
    I'm wondering if HDMI is somehow the factor here? Is it worth getting a Display Port cable?

    For #1

    For #2 most non-Apple monitors do respond to the Brightness controls on the KB
    Mini display port usually works better than HDMI

  • HT202856 Can the Mac Mini (Late 2014) support 4k display @ 60 Hz via the DisplayPort?

    Dear Experienced Apple Guru,
    Apple made it clear on the Tech Specs for the Mac Mini (Late 2014) that a 4k display can be supported via the HDMI port at 30 Hz. But, can we also be clear how many Hertz the Mac Mini can handle with a 4k display via the Mini DisplayPort (Thunderbolt 2)?
    I have a site linked here saying that the DisplayPort 1.2 can handle up to nearly 20 Gbps, thus can handle 4k display at 60 Hz:
    "DisplayPort version 1.2 can support video resolutions of up to 3840 x 2160 pixels (4K) at a refresh rate of 60 Hz, and it supports all common 3D video formats. In terms of bandwidth, it can manage 17.28 Gbps. Version 1.3, when it arrives, will support up to 8192 x 4320 (8K) resolution, or two simultaneous 4K streams. It will also double bandwidth to 32.4 Gbps.
    Meanwhile, HDMI version 1.4 is the most common at the moment. This supports the same 4K resolution as DisplayPort 1.2, but at just 30 Hz (or 4096 x 2160 at 24 Hz). HDMI 2.0 is new on the scene in a few devices such as this Sony TV. This doubles the refresh rate to 60 Hz as well as increases bandwidth from 10.2- to 18 Gbps."
    Thanks,
    Trevalyn

    That have enabled DP 1.2 on their monitor and used a DP 1.2 cable but still only get 30 Hz at 4K.
    The MAC does not support MST

  • Does mac mini (late 2014) supports dual-band wifi sharing?

    Hello,
    First of all, i'm not native speaker, so, please excuse my poor english.
    I have a mac mini (late 2014) and use the wifi-sharing feature of yosemite.
    (Ethernet is connected to Mac mini and other devices such as mac air are connected to Mac mini through wifi)
    For wifi-sharing, channel 44 is used, and as i know, it is located on 5Ghz band.
    By the way, i plan to buy a sony srs x7 bluetooth speaker which also supports airplay only on 2.4GHz wifi internet.
    If i wanna connect that speaker to Mac-mini's hotspot, should i change the wifi-channel of mac-mini to 2.4GHz band? or, can mac mini provides wifi hotspot for both 2.4GHz and 5GHz simultaneously?

    Bluetooth is a different network than the wifi network. BT is 2.4 GHz only while wifi cn be 2.4 and/or 5 GHz.
    Your BT speakers will work fine using the BT capability of the Mac

  • Recommended Mac Mini (Late 2014) Displays

    Just purchased the Mac Mini (Late 2014) with Yosemite (latest version).
    I need to purchase two displays, one connected to the HDMI port, another connected to the Thunderbolt 2 port.
    Does anyone have any recommendations for displays that would suit my set up?
    I will be using the displays for working in Pro Tools. One display for the edit workstation, another to watch the movie on.
    Cheers,
    Lou.

    I should have added I always recommend getting a display that you've seen in action. What gets a good review isn't necessarily a good display for you. I must admit that more than once I've visited a big box store and then checked out online prices and ordered elsewhere - if the big box didn't honor the low price I found. Do check out other Dell displays (though avoid their lowest end models). Dell has some very good displays in the $150-$200 range (or lower if you catch a good sale).

  • Sleep on the mac mini late 2014 strange behaviour

    my system specs are:
    Late 2014 mac mini.
    16GB Ram
    1TB Fusion drive.
    Recently I decided to completely reformat my fusion drive and pop a clean copy of yosemite on. All seems well. I have power nap enabled and wake for network access turned off.
    Recently my mac has been asleep as normal and waking up for power nap activities which is all normal. I sometimes look at the white led to know its ok as it is pulsing which is good. Last night and the night before that, the while light has been pulsing and then last night I saw that it was off. I was still able to wake the computer but noticed this in the console log:

    Normally and correct me if I am wrong power nap would cause the computer to wake every hour?
    It doesn't explain why my mac goes into like a deep sleep but I am still able to wake it up. There is no process bar or anything to indicate that it has gone into safe sleep.
    I have checked the hardware and there are no problems. Disk permissions there are no errors. everything seems ok?
    I was wondering if anyone else with a mac mini late 2014 has or have been having the same problem?
    Many thanks

    You asked "Normally and correct me if I am wrong power nap would cause the computer to wake every hour?"
    During Power Nap normal TM backups still happen so if you have Power Nap and default TM settings, TM will still backup every hour.
    Otherwise I have no info on your other problems

  • Mac mini Late 2014 screen flicking

    Just got  the Mac mini Late 2014 a week ago. It serves me well except the screen flicks randomly.
    I have connected Mac mini to two BenQ monitors, one via mini-display port HDMI adaptor (lets said this is port A), another one via mini-display port to HDMI or HDMI cable directly (tried both) (lets say this is port B or HDMI).
    The issue is, screen from port B or HDMI flicks randomly, sometimes 1 or two times within a minute, sometimes even half hour or an hour without issue.
    Connection with port A is always good, no flicking, I even switched two monitors, the problem still there, so it shouldn't relate to the monitor.
    I also tried different mini-display to HDMI adaptor on port B, also tried different HDMI cable, the problem still exists.
    I have no idea what happened here.
    Maybe something not related, but I want to mention, When setting up the new Mac mini, I tried to migrate my old account on Macbook Pro (Mavericks) to Mac mini, but It was interrupted, (the user accunt was created, but then I manually migrated some other stuff manually), not sure if this interruption plays a part in this screen flicking issue.
    Any idea? Thanks for any helps in advance.

  • MAC Mini late 2014 Sleep Wake issue

    I just bought a MAC Mini late 2014 version with Yosemite pre-installed, and got a similar sleep wake problem.
    It's connected to an ASUS IPS 27" screen using HDMI interface. When the Mac goes to sleep after 15 min, or when I press the button to force it to sleep.
    If you type on the keyboard and the trackpad within 1 minute (before the screen also goes to sleep because of no HDMI signal), then the wake up will work.
    If you wait till the screen goes to sleep also, then no matter how hard you pound on the keyboard or on the track pad, the MAC will not wake up.
    The only way to wake it up is to power off the screen, then power it on again. Then type on the keyboard or move your track pad while doing that.
    This is really annoying. I have to set to "Never" turn the display off to avoid this issue.
    Called the Apple tech support who recommended I set up the energy saver like this below. But still could not fix the issue.
    He told me to bring the Mac mini back to the shop to check.
    I doubt it's a hardware issue. My theory is that this  could be a software bug that somehow
    the setting of "Prevent computer from sleeping automatically when the display is off" is not in effect even if you turned it on in the power saver preference.
    So, when the computer goes to sleep, there is no more HDMI signal, then the screen also goes to sleep.
    And if "Prevent computer from sleeping automatically when the display is off" is not in effect, then even if you type on the keyboard, the computer will not wake up as the screen is asleep. The screen will not wake up as no HDMI signal comes from the computer.
    This turns into a viscious cycle, or a deadlock. Nobody is waking up.
    This is simple logic. I don't know why systems are designed to work like that. Just too annoying....
    I hope apple can fix this software bug asap.
    I did try to convert my HDMI cable to min-display port and try to plug that into the thunderbolt port to see if it helps.
    The same issue appears. The only difference is, with the HDMI port, once I am able to wake up the computer by power cycling my screen, i will see that I am prompted with a login screen, even if I set up my computer to auto login.
    but when I use the display port, when I managed to wake up the MAC, it bypasses the login screen.

    Some updates on this. I tried two other 22" screen. Both of the seems to be working fine with sleep wake, but takes between 40 sec to one min to wake up after you typed something.
    Topcon hdmi 22"  screen
    17 sec after keystrokes to turn wake screen
    40 sec to wake computer
    AOC  hdmi  22" screen
    19 sec after keystrokes to turn wake screen
    38 sec to wake computer
    I tried to switch to two other HDMI cables to see if it'll improve the situation of my original ASUS VX279 IPS HDMI screen.
    But it didn't. Still never wakes up after it the MAC goes to sleep until you power cycle the screen.
    I guess there is some hardware compatibility issue here.
    Let me bring my mac mini to the shop to see if a replacement will help.

Maybe you are looking for
