Upgrade to 10.6.7 Fans full blast and Screen washed out

Update went well but after restart, the icons, finder windows, system preferences all look washed out. It is almost like they are 8 bit color not 24 bit color. At the same time the fans go crazy at login and then settle down later. Logged in with Safe Mode and it did not change anything. I reinstalled from Combo, still no joy. Any ideas?

Update: The fans seem to have settled down, maybe it was an update to Spotlight?
Screen still washed out. It looks like when you attach an external monitor and you do not have the cable fully set. In Finder, you don't see light gray lines, in Excel, you don't see the grid. You could also say that the resolution is not at "millions of colors" but at 256 or less.

  • Sleeping G5 often makes fans run full blast and machine unresponsive

    the only thing new lately is that I installed Leopard 10.5.3 on my dual 2.0 GHz G5 tower.
    I usually sleep my machine all the time
    now it's a crapshoot whenever I sleep it whether or not it will go to sleep normally, or freeze in a state of screenless unresponsiveness with the fans running on full blast with no way to stop except a hard shut down or power kill
    other than this the machine is literally working just fine. Never interferes with my work.
    I don't know if this is 10.5.3 related or not, but I do wonder.
    I started up from an applecare disc and did a full diagnostic and everything checked out
    I guess I'll have to test Tiger sometime again but that'll be a pain because I'm already addicted to Leopard
    I just hope this old faithful tower isn't going dead on me. and I wish there was some official word if this was just a 10.5 thingy

    I believe I have solved this problem for now.
    I opened up my G5 and used compressed air to blow out all the months of dust buildup in the machine.
    I re-seated every single removable component inside (RAM, PCI cards, graphics card, etc)
    I also pushed the PMU reset button once and then put the machine back together.
    I proceeded to sleep it and wake it up about 5 times in a row, and it didn't exhibit the blowing fans problem and the light was "snoring" as it normally should in sleep mode.
    A few days later, the machine hung up after being put to sleep AGAIN with the fans kicking up and the light on my cinema display staying one dim level without the "snoring."
    This time I disconnected my Belkin USB hub and I have not seen the problem resurface since.
    The interesting thing is that cleaning out the machine and resetting the PMU sure seemed to help.
    So maybe it was a combination of things that were the culprits.
    I also wonder if I can ever use this perfectly good and only 1 year old Belkin USB 2.0 hub ever again.
    My father uses the same model on 10.5.4 as well on his MacPro without any problems. I am on a G5.
    I wonder if there's a firmware on the Belkin USB hub that could be in need of upgrading or if I simply cannot use this hub w/ this computer anymore.
    (luckily I don't need it urgently right now)
    I will report back if the problem happens again, but for now, since the computer has been sleeping totally fine for days now since removing the USB hub, I am marking this question as answered and hope that this info can help other people.
    If anyone has anything to add to this thread or knows about the specifics I've discussed above, please feel free to respond more.
    Thank you

  • Suddenly no video, fans full blast?

    I've had absolutely no problems with my MacPro until tonight; I heard it wake from sleep but my monitor didn't wake with it. Clicking/typing seemed to work as usual, I just couldn't see anything. I restarted, and my CPU fans started running full-blast and wouldn't stop. Still no monitor. I have an 8 month old top-notch video card (not sure of the model, since I can't use the machine). Does it sound like my video card died suddenly?

    The fans are set to High by Hardware at Startup.
    When the software is running properly and not crashed, it reads the temperatures from several sensors multiple times a second and sets the fans to an appropriate speed. If the software does not get around to it, the fans revert to high to avoid possible heat damage to the computer.
    Fans running full blast is an indication that the software has crashed.
    The caps-lock light on most Mac keyboards is under software control. No response to caps-lock = software not running properly.

  • G5 Quad, fans @ full blast & random sleeping..

    I'm using a PowerMac G5 Quad, 2.5ghz, running OS x 10.5.8 I have a problem with random sleeping,
    (the Mac, not me LOL). Sometimes it will go for days, run all night, with no problems.
    Then it suddenly goes to sleep. It's not overheating, I've cleaned it out regularly & have temp monitor running.
    It has done it within minutes of starting up. After it goes to sleep it can be woken with a mouse click of keyboard stroke,
    and 9/10 times everything is where it left off. It has crashed, but comes back OK.
    I have read a lot of stuff about firmware updates, but not sure wether to proceed.
    Another symptom is constantly noisy fans.
    How can I tell which firmware is running on the machine now?
    Can anybody advise a course of action?

    Still have fans @full blast at all times.
    What controls the fans? Is there somthing else I can re-load or reset?
    There's always the SMU reset: http://support.apple.com/kb/HT1436
    The fans are controlled via the SMU, which has a watchdog timer running which is reset when control comes from the CPU running the system piece that monitors the thermal state of the machine.  That is why, when the system tanks, the fans will firewall as a safety measure.

  • I have a need to update my OS. Should I go slowly and move to Lion (10.7) or go full blast and update to Yosemite (10.10)?

    I have a need to update my OS from 10.6.8. Should I go slowly and move to Lion (10.7) or go full blast and update to Yosemite (10.10)?

    Before embarking on a major OS upgrade, it would be wise, advisable and very prudent if you backup your current system to an external connected and Mac formatted Flash drive OR externally connected USB, Thunderbolt or FireWire 800, Mac formatted hard drive. Then, use either OS X Time Machine app to backup your entire system to the external drive OR purchase, install and use a data cloning app, like CarbonCopyCloner or SuperDuper, to make an exact and bootable copy (clone) of your entire Mac's internal hard drive. This step is really needed in case something goes wrong with the install of the new OS or you simply do not like the new OS, you have a very easy way/procedure to return your Mac to its former working state.
    Then, determine if your Mac meets ALL minimum system install requirements.
    OS X 10.7 Lion system requirements
    Purchased emailed download code here.
    http://store.apple.com/us/product/D6106Z/A/os-x-lion
    To use OS X 10.7 Lion, make sure your computer has the following:
    An Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor
    Mac OS X v10.6.6 or later to install via the Mac App Store (v10.6.8 recommended)
    7 GB of available disk space
    2 GB of RAM
    To install OS X  10.8 Mountain Lion, 10.9 Mavericks (free upgrade, but currently unavailable) or OS X 10.10 Yosemite (currently available free upgrade) you need one of these Macs:
    OS X 10.8 Mountain Lion purchased emailed download code here.

    Mac mini (Early 2009 or later)
    Mac Pro (Early 2008 or later)
    Xserve (Early 2009)
    Your Mac also needs:
    OS X Mountain Lion, Lion, or Snow Leopard v10.6.8 already installed
    2 GB or more of memory (I strongly advise, at least, 4 GBs of RAM or more)
    8 GB or more of available space
    Next,
    If you run any older Mac software from the earlier PowerPC Macs, then none of this software will work with the newer OS X versions (10.7 and onward). OS X Snow Leopard had a magical and invisible PowerPC emulation application, called Rosetta, that worked seamlessly in the background that still allowed older PowerPC coded software to still operate in a Intel CPU Mac.
    The use of Rosetta ended with OS X Snow Leopard as the Rosetta application was licensed to Apple, from a software company called Transitive, which got bought out, I believe, by IBM and Appe  could no longer secure their rights to continue to use Rosetta in later versions of OS X.
    So, you would need to check to see if you have software on your Mac that maybe older than, say, 2006 or older.
    Also, check for app compatibilty  here.
    http://roaringapps.com/
    If you have any commercial antivirus installed and/or hard drive cleaning apps installed on your Mac, like MacKeeper, CleanMyMac, TuneUpMyMac, MacCleanse, etc. now would be a good time to completely uninstall this apps by doing a Google search to learn how to properly uninstall these types of apps.
    These types of apps will only cause your Mac issues later after the install of the new OS X version and you will have to completely uninstall these types of apps later.
    Once you have determined all of this, you should be able to find the latest versions of OS X by clicking on the Mac App Store icon in the OS X Dock and then login to the Mac App Store using your Apple ID and password and if you purchased a download code, input that code.
    You can then begin the download and installation process of installing the newer versions of OS X from the Mac App Store.

  • Mac Mini G4 won't boot; fan full blast . . .

    Hello!
    I was using my G4 Mac Mini when it decided to re-boot itself, and on start-up, all I heard is 1 loud whrrring sound from the fan, a short pause, followed by continuous whrring sound from the fan going at full blast (very loud!). The screen shows nothing.
    I've tried the troubleshooting steps in the Apple site but nothing seems to work. Each time I start it up, it does the same thing.
    A few months back I'd the unit repair under warranty by Apple (replaced logic board). So it's quite frustrating to have it down again - and now it's out of warranty.
    Any ideas?
    Thanks.
    Mac Mini G4 Mac OS X (10.4.8)
    Mac Mini G4   Mac OS X (10.4.8)  

    It's perhaps telling that the problem occurred after the system forced a reboot. That tends to suggest there's a significant fault - likely hardware, since if the issue was with MacOS it would not be likely to cause the fan to ramp up to full speed on startup with the screen showing nothing.
    You mention that you've tried troubleshooting steps, though not which ones. Likely, given that it features in G4 mini troubleshooting of startup issues, that would have included a PMU reset, but if you haven't yet tried that, do so. I would not hold out much hope that it will assist in this situation, but the power manager is the only hardware component that could cause this sort of potential issue, and the only one that can be reset by the user.
    Assuming a PMU reset doesn't help at all, and since the system doesn't show any display, it's not worth trying to boot from the original install disk to run the hardware test since the system isn't even managing the power on self test, thus won't move on to loading MacOS. At that point, I'd say you should take the mini to an Apple store if you have one in your location, or to an Apple authorized service provider for them to give you an idea of what is wrong and what it would likely cost to repair it.
    If you don't want to do that, the only option is to open the system and examine it yourself. The problem with that, however, is that there really aren't any user-servicable parts inside so other than checking that everything is correctly connected and properly seated, there's really not much else you can do.

  • System fans full blast

    Hi there. I have a Power Mac G5, dual 2.7's, and I turn it on this morning and the system fans immediately kick on full blast, before the OS even loads. They won't slow down or kick off unitil I turn the computer off. I tried resetting the PRAM and SMU, ran the Apple Hardware Test, and it said everything was ok. This thing sounds like a vaccum cleaner, please help!

    Yeah, count me in - dual 2.7.
    New processor and still sleep problems, especially if left alone for long periods of time.
    Here's what I have done so far (still in process):
    1. Erase and install of OS X via disks included with computer for HDD installed in the lower “B” slot. The HDD installed in the “A” slot at this time had all of my software and 10.4.6 with all software updates installed. Install crashed at the end of second DVD and computer had to be shut down via the power button.
    2. Removed primary HDD from the upper “A” slot and replaced it with the newly formatted (erase and install) drive that previously occupied the lower “B” slot.
    3. Started computer, entered basic information and allowed wireless keyboard and mouse to pair. Did not set up AirPort at this time.
    4. Attempted sleep with DVI connected only. Left machine sleep automatically for one hour, and then restarted successfully.
    5. Plugged in USB 2.0 cable from Apple Cinema Display into main I/O in the back of the computer. Let machine sleep automatically for one hour, and then restarted successfully.
    6. Plugged in FireWire cable from Apple Cinema Display into main I/O in the back of the computer. Let machine sleep automatically for one hour, and then restarted successfully.
    7. Plugged in iSight cable and Mighty Mouse into Apple Cinema Display. Let machine sleep automatically for one hour, and then restarted successfully.
    8. Plugged in FireWire 800 cable from external HDD (powered on) into main I/O in the back of the computer. Let machine sleep automatically for one hour, and then restarted successfully.
    9. Plugged in USB 2.0 cable from iPod nano into main I/O in the back of the computer. Let machine sleep automatically for one hour, and then restarted successfully.
    10. Plugged in FireWire cable attached to iPod photo and FireWire cable from CompactFlash card reader into FireWire PCI card. Let machine sleep automatically for one hour, and then restarted successfully.
    11. Computer not making POST “gong” on restart. Reset PRAM successfully.
    12. Shut down computer and reset SMU. Removed all RAM except innermost two slots.
    13. Restarted computer and allowed it to sleep automatically for 45 minutes. Woke from sleep successfully.
    14. Shut down and remove first pair of DIMMS and replace with next pair. Let computer sleep automatically and wake after 45 minutes.
    And 4 more GB's of RAM to go....
    This unit just had a new processor installed.
    Since then, I have been on the phone with AppleCare for hours. Every tech blames everything except the computer. Good luck, all.

  • Ix4-300 fan keeps running full blast and the NAS never comes online

    When I turn on the ix4-300 after a couple of seconds its fan starts running full blast but the NAS never comes online.  The NAS lcd was damaged in the move so I don't know what is going on, it was working fine for a couple of weeks (with the damaged lcd) but this started happening a few days ago.  Things that I've tried:
    Used the other ix4-300 (I've 2) with the faulty NAS... same result
    Let the NAS run with full FANS for 4 plus hours ......, Still didn't come online
    Also both the blue and white light are constant .... no blinking whatsoever.
    Any ideas ...

    It could be the device itself. Is it covered by the warranty?
    Are you concerned about retrieving the data or do you just want the device back up and running properly?
    If you are not concerned about data, you can try the following procedure at your own risk:
    Power down the device and reseat all the drives in the device. Power the device back on.
    If this doesn’t allow unit to boot, continue with below process.
       1. Turn off the device and pull out all the drives.
       2. Place any other drive 2, 3 or 4 in the first slot and boot up the device.
       3. Wait for sometime as the boot-up process can be slow.
             a. If it doesn’t boot, try another disk in slot 1.
       4. If it boots up correctly, insert another disk in slot 2.
            - Check UI for disk detection.
            a. If second disk is detected, turn it off, place disk 3 and 4 in unit and boot up.
            b. If it doesn’t boot-up correctly, remove 3 or 4 and retry. You may need to try to determine if 3 or 4 is bad in this case.
       5. Recreate the volume if it doesn’t start regenerating automatically

  • My hard drive is randomly on full blast and the CPU at 50% usage...???

    Out of the blue all of a sudden my hard drive goes to work at full capacity and the CPU is at 50% usage. iotop shows nothing. I close Chromium, Gedit, and my Terminal and the hard drive continues for a minute on full blast.
    I hate when the computer does these things without my approval. What's going on here?

    @ewaller: Exactly! iotop *should* show something but it doesn't. If it happens again, I'll have a look at the logs. Which logs should I look in?
    @litemotiv and egan: Yeah, i know updatedb does this sometimes, but in this case it lasted much much longer and updatedb didn't show up in iotop like it normally does. Also, i've kept a very very detailed log of every single thing i've installed or which settings I've modified. This incident has only happened a few times so I don't think it's a package or a cronjob. I don't think i have any cron jobs except for one. Last time it happened randomly hours into my session.
    I use Gnome. DAEMONS=(syslog-ng dbus hal networkmanager !network netfs alsa !avahi-daemon @crond)
    A bad sector seems like a possibility!

  • Fans full blast another case 21.5" model

    At first, my new IMac was having an internal speaker problem, the apple technician came to replace the logic-board, since then the fan turns into full blow all the time. The noise is unbearable. The technician came to replace the logic-board again and then the third time, the power supply. Now it took more than 4 weeks and the issue there. The SMC reset has been tried as well.
    I filed a complaint at Apple customer service and requested a new replacement since I bought it just December last year. I was told to wait and the response might not be positive. What can I do?

    I wonder if some owner of the IMac 21.5" can run iStat on their machine and post their screenshot here, mine is http://picasaweb.google.com.hk/lh/photo/q3ueZkPeAnlIFlXj7c6M_A?feat=directlink
    and I suspect that some temperature is missing.

  • Fans running full blast and CPU

    Hi,
    I have a late 2003, early 2004 dual 2.0 ghz G5,1 gig ram running OS x 10.4.7. Everything has been fine up until a few weeks ago the fans started running at full speed when the system was on, no variation, just full speed. I ran the hardware test disc and I get the following error, 28 seconds into the test,----2SAM/1/3:CPU B AD 7417 AD4 post/2176/0---
    I have talked to a service centre close by and they have told me that the CPU is bad and needs replacemwnt to correct the fan problem. Everything runs normally as it used to, sleep, wake, all function fine. Do I need a new CPU or is their something else causing the problem??

    Hi DS,
    Thank you for your quick reply and insight.
    I do not have the full version of Hardware Monitor as of yet, just ordered it tonight so will have it very soon and then will be able to have full info. The demo version gives me the following info.
    1) CPU A die temp--28.8 degrees celsius
    2) CPU B Die Temp--29.1 degrees "
    3) Drive Bay-------24.0 degrees "
    4) Main Logic Board air inlet---24.0 degrees "
    5) Main Logic Board ambient--27.6 degrees "
    6) Main logic board backside--27.0 degrees "
    7) Memory controller heatsink--31.8 degrees "
    8) Processor Card A Ambient---26.5 degrees "
    9) Processor Card B Ambient---26.0 Degrees "
    10) Smart Disc Temp----26.0 degrees"
    This is after the system has been running for the better part of an hour with the room temp. at 65 degrees Fahenheight. Programs running at the same time that these temperatures where taken are as follows-- Quark express, Garage Band, Aperature, MS word, Illustrator 10,Firefox, Filemaker Pro. With all those programs running activity monitor for CPU reads as follows--
    % user--3.5
    % system--2.0
    % nice--O
    % idle---94.5
    System memory shows as having 330 mb free at the same time
    Fan speed is a constant " turbo" sound, no variation in speed or sound, very loud.
    It would seem that as you have suggested that I am getting a false reading from the Apple Hardware test as all readings seem to OK.What do you suggest that I try to do to bring the fan speed down to a normal level? It would seem that the dual CPU's are OK and that something else is causing the problem?? Would you agree? Appreciate any help that you can suggest.
    Thanks Much

  • When I use my computer for any amount of time all of a sudden the fan starts up full blast and everything freezes

    Nothing works after this happens its happened 3 times now, the first I just forced shut down and re started, the second I force shut down and left it off for the night, the third time I let it run like that for a bit to see if it would control itself but after a small amount of time I forced shut it down again.

    If you have more than one user account, these instructions must be carried out as an administrator.
    Launch the Console application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
    Step 1
    Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
    View ▹ Show Log List
    from the menu bar.
    Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time after  you had the problem. Select the messages logged before the boot, while the system was unresponsive or was failing to shut down. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message (command-V). Please include the BOOT_TIME message at the end of the log extract.
    If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message.
    When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
    Please do not indiscriminately dump thousands of lines from the log into this discussion.
    Important: Some private information, such as your name, may appear in the log. Anonymize before posting.
    Step 2
    Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the entire contents of the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post any other kind of report — it will be very long and not helpful.

  • Since upgrade to 10.6.7, fans speed up and never slow down

    I have an Intel iMac, 2.8 GHz i7, 8GB RAM
    Just as the subject line indicates:
    After upgrading to 10.6.7, when my iMac starts to heat up, the CPU fan RPM will increase but it will not slow down until I reboot - even if I allow ample time for the machine to cool down and let it sit idle for hours.
    Right now, the CPU temperature is only 100 degrees F, utilization is at 1%, and the very loud CPU fan is still running at 4000 RPM.
    I've reset the SMC multiple times, and this doesn't help.
    The most telling aspect is that in the seven months prior, the fan would slow as the machine cooled off.  Not so with 10.6.7
    Anyone else experiencing this?
    Thanks

    Resetting the SMC was my first thought, but you have done that. You might also try resetting the PRAM/NVRAM:

    After that if the issue persists, I would call AppleCare.

  • Fans full speed and LCD temp sensor issue

    Hi
    So... Last week I replaced my internal iMac (mid 2010) HDD with an SSD. I knew that there would be the fan problem but I just shorted the HDD temp cable infact the HDD iMac runs on about 1000 rpm. The problem is that the CPU and Optical Drive fans run at about 4000 rpm! I googled my problem and I realized that those two fans are not related to the HDD temp sensor cable (RIGHT? ) . But when I removed the LCD panel of the iMac I accidentaly damaged the LCD temp sensor. So now I think that the CPU and OD fans are related to the LCD Temp Sensor.. Replacing it I should have all my problems solved.. Does it make sense? Thank you guys for your answers.
    P.S. I resetted SMC and all the other stuff..!

    Bring it in for service.  If you feel you damaged a sensor, you could have damaged more.  Best to have a trained eye make sure nothing else is bad.
