Which iMacs to Avoid Purchasing?

Good Morning - Reading Rod Hagen's post, with attachments, describing failed logic boards due to bad capacitors makes me wonder which iMacs, new or used, are safer to buy. I've had iBooks, eMacs, and now a PowerBook G4 for years, all wonderful machines, and am now looking to buy a used iMac G5. My question is then, based on the long and wide distribution of these bad capacitors, are there specific early iMac models to avoid, or is buying any machine using capacitors a typical gamble? Thanks much.

I would suggest avoiding the first two models, the Rev A and the Ambient Light. The iSight model should be fine it seems to have many fewer problems than the first two, but might I suggest buying an intel machine? Even a refurb intel iMac has a history of fewer problems than the G5s and it will come with a warranty, you can also buy Apple Care to extend that warranty.

    If they are the grey discs which came with the iMac, then they will be machine specific and will not work on the MBP anyway. You will need to purchase a retail copy of Snow Leopard from the Apple Store for about $29 and upgrade from that. I presume your MBP is Intel and not G4.

  • Which used iMacs to avoid?

    It seems with Intel iMacs, the early 2006 models are to be avoided due to overheating and hardware failures. Is that an over-simplified statement? Are the late 2006 models any better?
    Some of the recent posts about even newer iMacs have me concerned: making noises, etc.
    Is there perhaps a general consensus on which models to avoid?

    I have a 17" Late 2006 2Ghz C2D iMac with 3GB Ram and the ATI X1600 GPU.
    The Biggest Issues was that the LCD developed a Skinny Solid Green Horizontal line right done the middle. And this is a Common problem with Early and Late 2006 17" Models ( I don't know about the 20" or 24" models).
    I'm not familiar about the over Heating Issues. I opened up my iMac ealier this year and I peplaced the stock 160GB HD for a 500GB HD. No easy task but it is it can be done with time taken. All I noticed was it was kinda dusty in there. I didnt have an air can so I clean off what I could and cleaned out the fans a bit. The Stock 160GB Drive was still in perfect working order, I just needed the extra space.
    When it came to repairs over the years
    #1 A new Logic Board. The one it had was fine but I keep hear a slight click noise before any sound would get played. Turned out it was normal to happen and it's a power saving feature that shuts down the sound when not in use and imediatly comes back as soon as sound gets played. Tech dudes at the Apple Store didn't even know about that sound until they pluged in they're headphones to other MacBooks and MacMinis which did the same. So I guess I made them aware LOL. They replaced the Logic board anyways
    #2 Super Drive. After a few months, it vibrated chattered, and scratched my DVDs. They replaced it.
    #3 The LCD... Replaced AFTER my 3 year AppleCare coverage expired by a month. Apple replaced it free of charge as it is a common issue with all 2006 models.
    Other than that, it's been a great Mac in terms of performance. I gave it to my Parents to rid them of a custom built PC I made them 5 years back so I can hook them onto Mac OS X. Mom now uses the Mac everyday.
    But keep an eye on the refurnished Mac page. Apple puts up lots of great deal every day, and they are all covered with applecare with the option of adding an additional 2 years ( 3 Years total ) of coverage. It's the only way I would by an iMac @ discount. If anything goes wrong with 1 you by elsewhere with no coverage at all, ur pretty much on your own.

  • I have a mid-2010 iMac and just purchased a 2TB TC, can't join existing wireless network with AC standard so attached to iMac via ethernet with TC wifi turned off.  How do i access TC now? not showing up in disk utility or on desktop. working fine with TM

    I have a mid-2010 iMac and just purchased a 2TB TC, I just found out that it can't join existing wireless network with new AC standard so attached to iMac via ethernet with TC's wifi turned off.  How do i access TC now? not showing up in disk utility or on desktop. It is working fine with TM.  My cheeper seagate drives etc kept crashing, so i didnt trust cheeper back up options anymore.  Connected those drives to TM via firewire and could see the drives and access them.
    Also, I didn't want to bridge TC with my new fios router that I paid 100 dollars for, to get N speed and also paying 10 dollars more a month for fast speed.  I heard that bridging slows down everything and then there can be port issues with mail etc.  I connect to the internet via airport only and it is pretty fast. Getting over 50mbs downloads and over 30mbs uploads.  Plus everything in my home it connected to my fios router, airport express for music streaming, two apple tvs, vuezone camer system.  I really didn't want to monkey around too much with my system.  But are there other options to connect the new TC.  Can't find info anywhere for this and called apple who gave me the info above.  after hanging up, i see that i cant access my TC and I am wondering if i would have to reset it to turn wifi on again to make changes to the drive, turn off blinking light  or repair it in disk utility if it should become corrupted.
    For other with similar issues i did solve some other problems: when i connected it to my ethernet port on my iMac wifi stopped working.  Found that I had to turn off the ethernet in the system>network screen, but then TM didn't see the TC so i restarted after changes and then it saw it.
    Now a rant.  I can't believe in this wireless age that Apple would make a product that cant join a wireless net work.  The apple rep said i could return it and look for the previous TC that would join an existing wireless network.  Are we going backwards?
    Thanks!

    Ok... it is getting a bit clearer but there are still some questions.
    I connect to the internet via airport only and it is pretty fast.
    I was assuming airport in this statement in your first post meant the TC or the Express.. but I now realise we are still in the mass confusion stage where apple calls everything wireless an airport. So what you mean is the airport internal card of the computer??
    Also, I didn't want to bridge TC with my new fios router that I paid 100 dollars for, to get N speed and also paying 10 dollars more a month for fast speed.  I heard that bridging slows down everything and then there can be port issues with mail etc.
    I think this is mistaken.
    Putting the TC in bridge mode plugged into your FIOS will not slow the network.. nor will it cause mail or port issues.. in bridge the TC is just a fancy WAP and switch plus the network hard drive.
    If the computer is close it will be faster than the FIOS.
    You can run both wireless networks with different names.. so it is clear which is which. But you can also setup roaming so the computers themselves pick which is the best wireless.
    I tried extending the wireless net work and tried joining wireless network, but the TC kept crashing and I had to keep resetting the TC.  the Apple support person said these, extend wireless network and joint wireless network, are no longer a connection option with the new TC because of the new AC protocol.
    Thanks again!
    You cannot extend to a non-apple wireless router.
    You cannot use join a wireless network because when you do the ethernet ports will be cut off.
    But that has not changed.. I don't think Apple support is correct.. there has been no change with the AC model.. it is simply a fact that apple routers do not work in join wireless mode other than as a dumb client. The same applies to AC as to the earlier version.. but I have asked another person to check this.
    Join in the express is the only apple router that still allows an ethernet connection.
    For now you best use of the TC is bridged to the FIOS. Wireless you can sort out between several options.

  • Which mac should i purchase...please help!!!!! Its my first mac!

    Im in a dilema...I solely want to produce music with Ableton and I will be using Final Cut Pro extensively...im debating on which MAC system to purchase....Im highly interested in the new macbook but im not sure if the laptop will sustain the tasks I want to do...maybe a macbook pro or powerbook? or should i just skip the laptop idea and get an imac or desktop mac! Please help?

    any mac would work fine using ableton live, but if you're going to be doing final cut work, you're going to need more graphics power. if you need a portable, the macbook pro should do you fine. a powerbook will work, but with final cut the macbook pro is literally at least 4 or 5 times as fast. if you don't need a portable, either the 20" or 24" imac will work fine, the smaller one doesn't have dedicated graphics, so it won't do. if you are working with serious, professional media or HD media in final cut, the mac pro is the only way to go.

  • I do a lot of CAD work and 3D modelling on my aging HP. Which iMac would best suit?

    I do a lot of CAD work and 3D modelling, (Sketchup), on my aging HP.  Which iMac would best suit my needs ?

    I agree with RRFS.
    If you can afford it, Custom spec out and purchase the best components for your iMac.
    Custom order the fastest i7 CPU, custom GPU (if you can afford it order the 2 GB VRAM GPU, otherwise get the 1 GB VRAM GPU), add the custom largest SSD.
    Purchase 16 GBs of RAM or more (the new iMacs can take up to 32 GBs of RAM) from online memory suppliers like Crucial memory or OWC. They are cheaper to buy RAM from.
    iMacs are not designed and are not user upgradeable for components other than RAM.
    Purchasd the best you can afford now as it will be much harder to get what you really needed later.
    Also, I highly recommend with whatever iMac purchase you make, you budget for 3-year extended AppleCare.
    iMacs have, somewhat, a regular component failure history. I believe that these failures are due to how much warmer iMacs run than anything else. Purchasing and having extended AppleCare will give you peace of mind and free warranty service for three years.
    Good Luck on whatever you decide.

  • How to avoid purchase req and stock transport order to take part in MRP.

    Please suggest how to avoid purchase req and stock transport order to take part in MRP.

    hi,
    check the settings for the MRP type...there you need to show which doc will be taken into considerations...
    SPRO >> MM >> CBP...
    Under CBP check for the MRP settings where it is placed(check under master data settings)...and check for the indicator for PR's and STO's release orders under tab "Additional external req. in the reorder point planning"..

  • Opinions Please: Which iMac 'G5" to buy?

    Hello: I'm reading through these forums trying to decide on WHICH revision of iMac G5 to purchase.
    I have my choice of a used first generation iMac G5 which has the user upgradable feature. It comes with Applecare.
    I can also buy the latest version 2.1GHz model for not much more.
    Between these two models, which is the better choice. Is there any reason to purchase one over the other? I'm leaning towards the first generation because you can upgrade the hard drive to 500mb and I like that you can get inside to swap out user replaceable parts. What are the pluses for the latest G5 iMac.
    Thanks for your comments.

    As an owner of the rev C iMac G5, I'd consider the plus points of the machine as follows:
    Built in iSight. If you're an iChat AV user, this saves you the cost of a seperate iSight camera straight out of the box. The camera is beautifully integrated into the iMac case and is a very high quality. This also ties in with the fun but gimmicky PhotoBooth application.
    Frontrow. If you're a digital media fan (music, photos, videos & DVD) then I'd suggest going for the latest iMac G5 solely on the basis of Frontrow. Whlist the ability to drive media playback from a few feet away, as opposed to driving the same with a keyboard and mouse, might not sound like much of an advantage. Trust me, it is! The experience of kicking back with your feet up, drinking a coffee and "surfing" through iTunes or watching a DVD using the remote is just wonderful!
    The improved quality graphics card is worthwhile if you're a gamer or do anything particularly graphics intensive. This for me is even more true when you look at the 128MB Radeon X600 card compared to the original iMac G5 64MB nVidia FX 5200 card.
    The slightly slimmer case of the rev C iMac G5 is nice but hardly a deciding factor.
    In the interests of fairness, there are a couple of downsides. Firstly is the memory. The iMac G5 w/iSight only has one expansion slot, the other being occupied by a fixed 512MB memory card. You can add in another chip up to 1GB quite easily and relatively inexpensively. Adding in a 2GB chip however will set you back a small fortune at the moment.
    Previous iMac G5's had both memory slots available, so you could upgrade one of those to 2GB total inexpensively. Long story short, if you don't see yourself needing more than 1.5GB of memory then the iMac G5 w/iSight will be fine. Otherwise....
    The other consideration is the hard drive. The hard drive in the iMac G5 w/iSight is not user replaceable, so you're stuck with what the machine comes with (160GB in the 17", 250GB in the 20"). You can still easily expand by using an external FireWire 400 or USB 2.0 drive though.
    Unless the >1.5GB memory expansion/expense or the lack of a user replaceable hard drives are an issue for you, I'd suggest going with the iMac w/iSight. The iSight camera, Frontrow and the better machine spec will make it worth your while over the 1st gen iMac G5.
    Lastly you don't say if the 1st gen iMac G5 you're considering comes with a combo (CDRW/DVD-ROM) drive or a superdrive (CDRW/DVDR). Both of the iMac G5 w/iSight models come with superdrives.
    Let us know how you go on and what you ultimately decide on!

  • Which imac shall I buy ??

    Which imac shall I buy ??
    Uses include word processing and spreadsheets, light use of logic, some gaming and bootcamp. I will be getting it on finance over four years so want it to be future proof beyond this time . Thanks

    The iMac refresh usually comes toward the end of the end.
    No one knows exactly when, though.
    Something better, faster, cheaper is always around the corner.
    Buy what you need/want now.
    It isn't suddenly going to go obsolete.
    Budget and save to be able to purchase and register for the extended AppleCare plan before your free one year of service ends. This will extend the warranty repairs out to another two years.
    I highly advise doing this as iMacs have a long and uneven reliability history, IMO.

  • Which iMac to buy?

    I run my own small graphic design company and I'm currently running a Mac Pro and an employee is using a MacBook Pro. Both are running the necessary apps fine (CS3, Aperture, Final Cut Express etc.). I'm thinking about getting a desktop for my employee but budget is tight so I'm thinking about an iMac rather than another Mac Pro.
    So which iMac do I need? The system requirements for the software suggest the lower spec 20inch iMac would be OK (maybe with a RAM upgrade) but would I be better to get a higher processor speed and a better graphics card with the 24inch iMac? Money is tight so I don't want to buy something more expensive than necessary but I also don't want to spend less and then find it's sluggish or just doesn't work at all.
    Any ideas?

    Hi Jon,
    Just my 2 cents here. I purchased the 20" 2.66GHz but upgraded to 2GB RAM this past November. I use Final Cut Express and Aperture but not as a professional. But if I were looking to do this on a professional level, I would have purchased the 24" instead and definitely upgraded to 4GB of RAM.
    I would most likely have upgraded processor speed, I think 2.93 is next, then 3.06. As the software technology changes, so do the requirements for their use. I think spending the extra $$ now would be an investment in the future for you. Just my 2 cents.
    Another way to receive feedback or just search the forums is to go here to the FCE forum http://discussions.apple.com/forum.jspa?forumID=936 and the Aperture forums here http://discussions.apple.com/category.jspa?categoryID=184

  • HELP! I want to know whether my hand-me-down iPhone 4 is SIM/carrier-locked or not. I was given an iPhone 4 which I think was purchased outside the Philippines.

    I was given an iPhone 4 which I believed was purchased outside the Philippines. The previous owner had it jailbroken but something went wrong so it was stuck on DFU mode. So when it was given to me, I had it restored and updated via iTunes to iOS 5.1. I bought a micro-sim and inserted it on the sim tray. iTunes was able to detect the SIM card number and there was NO MESSAGE like the sim card is not supported whatsoever which can be usually seen in unsupported simcard. I thought everything went smoothly. But when I tried to set-up the phone, the SLIDE TO UNLOCK button is unresponsive. It doesn't work so I was stuck there and my iPhone cannot be accessed because of that. What shall I do? I have tried doing the hard reset several times, it still didn't work. I have tried restoring my iPhone three times but the slide to unlock is still unresponsive. I think the iPhone was able to detect my carrier simcard since it shows on the top corner the name of my carrier, mobile signal and 3g network. Now I am wondering as to why the slide to unlock button is unresponsive? Was it because of my iPhone LCD or was it because the iPhone is locked? Please help.

    according to some blogs, if the sim card you are using is unsupported, iTunes will show you a message that the sim card you are using is unsupported. But when i opened itunes, I didn't see that message. Instead, it was able to detect my sim card number. So I guess, the simcard is supported. It isn't the original sim, though. Then the phone was able to detect the mobile carrier, mobile and 3g signals. So iam wondering whether my phone is locked or was it a hardware problem?

  • Which Imac would be better for gaming?

    So i've got a choice between these two models -
    £1329.60
    3.1GHz Quad-core Intel Core i7, Turbo Boost up to 3.9GHz
    TB Serial ATA Drive @ 5400 rpm
    8gb Ram
    NVIDIA GeForce GT 750M 1GB GDDR5
    Apple care
    27 inch model
    3.2GHz quad-core Intel Core i5
    Turbo Boost up to 3.6GHz
    8GB (two 4GB) memory
    1TB hard drive1
    NVIDIA GeForce GT 755M with 1GB video memory
    Apple care
    £1407.60
    Basically, the decision is down to, do I want a slightly better graphics card and bigger screen, or a smaller screen and better processer?
    I just want to gauge opinions, i'll be using it as my day to day computer as well, some video editing, but nothing too strenuous. How big is the difference in graphic and processing powers.
    Thanks for your help

    With all due respect the question was "which iMac would be better for gaming?".  Key word here is 'better', not 'perfect', not 'ideal'; just 'better'. Unqualified answers and/or sweeping statements do very little to contribute to a discussion, let alone answer the question under consideration.
