Mid-2009 iMac w/ 4gb ram.  Since Maverick web pages load excruciatingly slowly (if at all).

My wifi is an Airport connected to Comcast modem (no issues prior to Maverick upgrade).  Sometimes if I turn off the wifi at the iMac end then turn it back on, and then reload the page, it'll come up at normal speed.  I've tried a Safari reset and disabling DNS prefetching with no effect.  Occasionally pages will load normally, but most of the time will be slow (at or below old dial-up speeds), and about 50% of the time the progress bar in Safari will go about 1/3 - 1/5 of the way and then just stop (with the page not loading at all).  Any ideas?  In advance, many thanks!

    Running a mid 2009 iMac on 10.7.5, 3 gb memory, 320 gb hd. 
    Suddenly the computer stoped reading DVDs and the only time I can read a CD is if I restart.  Quite often when I insert a CD it gets stuck and I cannot get it out until I restart and it shows up on the desktop where I can then eject it.
    I have checked and double checked the finder prefs and all looks normal showing a check mark on CDs,DVDs etc. (the ones I want to show up on the desktop)
    I have reset the PEAM, repaired permissions with both the disk utility on the computer and the disk utility when I start up in the Recovery Disk.  I did notice that sometimes the permission repeat the same correction several times before it moves on, and sometimes it doesn’t. I have Windows installed on a partition but I keep it unmounted until it is needed for my wife’s work.  The dock seems to be just fine and all the apps seems to run just fine.  When I insert a photo CD iPhoto does not open but when I insert a music CD iTunes does open. 
    Also, most every time I open iPhoto it takes a long time(sometimes as long as 2 minutes) for it to load.
    Sometimes my Mail (Mail 5.3) does not post new mail but most of the time it does. 
    Once and a while it seems like the computer slows way down but then it seems ok ten minutes later.
    All  of these ‘things’ seemed to have happen suddenly and I have not downloaded anything from the internet in some time.
    Of course the warranty and extended warranty are both no longer in effect having had this computer for more than three years.
    I am running Java and Adobe Player because some of the sites I go to a lot require both.

    I believe that insufficient RAM may be the source of some of your problems. If you have a RAM of somewhere 4 to 8GB, you will experience smoother computing. 3GB doesn't seem right, so you might want to learn more by going to this site:
    http://www.crucial.com/store/drammemory.aspx
    I don't know what know what's happening with your optical drive, but it seems you use your drive quite a bit. In that case, look into a lens cleaner for your machine. It's inexpensive, works quite well.
    I hope you'll post here with your results!

  • Can a Mid-2009 iMac (2.93 GHz Core i7) recognize a 3 TB HDD?

    I have a mid-2009 iMac with an almost maxed-out 1TB drive. As it turns out, Apple is replacing these drives as part of a recall, but clearly I need a larger capacity drive anyway. I'm looking at 2TB/3TB Seagate Barracuda XT HDD from OtherWorldComputing. Will this iMac handle a 3TB drive, or is it a safer bet to go with the 2TB?

    Yes, it will handle it, but the Thermal sensor is the issue...

    Since the late 2009 iMacs came out, replacing the hard drive has caused the internal Hard Drive Fan to start running at around 6000RPM.
    This is due to Apple replacing the external Hard Drive temperature sensor with a proprietary firmware and using the drives internal sensor.
    Replacement drives do not contain the firmware to deliver temperature data on the temperature sensor cable.
    When the iMac does not receive a good signal from the hard drive it puts the fan at full speed to protect the drive.
    If you replace your drive, your iMac will initially seem fine, but soon the fan will begin to speed up to full speed. Resetting the SMC (System Management Controller) will have a temporary effect, but again the fan will speed up.
    Fixes people have used in the past included:
    Using smcFanControl and the terminal to set a MAX speed for the fan and writing scripts to start this after every sleep/restart.
    Shorting the temperature sensor cable (Not a possibility on 2011 iMacs) this tricks the iMac into thinking the drives temperature is very low, hence slow fan speed.
    Both these fixes are less then perfect and leave the drive in a dangerous situation with no protection from overheating.
    Another option people try is other Fan Control software. These programs will not work for this particular issue as they often only control the base speed, and if they do control the fans actual speed they rely on the temperature reported by the sensor which is now incorrect.
    HDD Fan Control
    HDD Fan Control works to fix this issue by reading the drives internal temperature using the S.M.A.R.T protocol and set the fans actual speed to a value good to protect the drive.
    It runs at startup and continually to always control the fan correctly, prevent the loud fan noise and protect the drive from overheating

  • Possible to create system software disc on USB flash drive to start Apple Hardware Test on mid 2009 iMac running OS X 10.9

    Is it possible to create a system software disc on a USB flash drive to start Apple Hardware Test on mid 2009 iMac running OS X 10.9?

    Hopefully, those dvd's are the correct ones. If not, it's possible to download the AHT for many models from Apple, & either make a bootable drive, or replace the files in the hidden /System/Library/CoreServices/.diagnostics folder.
    see  Download and run Apple Hardware Test (AHT) from a USB drive.
    There are additional download details in the comments  for some later models.

  • Printing from web pages is excruciatingly slow with most recent upgrades of Firefox .Use an iMac and an HP officejet printer. Printer works fine with Safari and woodprocessed files, but not with Firefox and web pages.

    Printing from web pages is excruciatingly slow since downloading most recent upgrades of Firefox Mozilla. I have a desktop iMac, OS 10.6.8, and an HP officejet printer 4500 G510n. The printer works fine with the Safari Browser and with woodprocessed files, but not with Firefox and web pages. Help please! It used to print fast with earlier versions of Firefox.

    Hello and welcome to the Apple Discussions Forum.
    I have hardly any experience with HP printers but since your posting has not been replied to yet I thought I'd offer some assistance.
    With the printer status and ink levels working, it shows that you have a connection to the printer. So I would look at the issue being with the protocol being used for the print queue on the Mac.
    Since you have XP and Vista working, I would check the printer queue configuration on either box. In XP, go to the Properties and select Ports. Click the Configure Port tab to view the connection. If you are using RAW, then this is known as HP Jetdirect-Socket on OS X. So if you are not sure what protocol was used before I would create another printer queue, this time selecting IP > HP Jetdirect-Socket. Then enter your IP address and select the K5400dn from the Print Using menu.
    If this still fails to print then please reply. There may be limitations with adding the HP driver this way that I am not aware of. There may also be other driver options you can look at, such as HPIJS. If Greg Sahli reads this posting he has expert knowledge on this matter and will be able to offer some guidance.

  • Adding ram to mid-2009 Macbook Pro - 4gb vs 8gb?

    I want to add ram to my mid-2009 Macbook Pro. It currently has 2gb ram. Any thoughts of whether I should upgrade 4gb or 8gb ram? It has a 2.26ghz intel core 2 processor. I only use the computer for internet and the occasional document editing.

    If your needs are that modest, then 4 GB is fine. However, Mavericks is designed to use as much RAM as is available, and so more RAM is always better.
    If I were you, I would put 4GB of RAM in, and then buy an SSD to replace the hard drive. You will be surprised how much faster it will be! It's the best way to extend the useful life of a older Mac.

  • Since update, various sites load very slowly and some do not load until "Reload Current Page" is clicked several times.

    Since Firefox update (6.0.2) many sites load very slowly and some do not load at all (green circle rotates infinitely) until "Reload Current Page" is clicked on 2 to 12 times.
    Returned to version 5. No more slow load.
    Automatically re-updated me to 6.0.2 and now slow again.
    Returned to FF 5 again and turned off automatic update.
    Downloaded 7.0.1 and the problem seems to be solved.

    Same here, only that updating to 7.0 or 7.0.1 doesn't seem to solve this issue. Seems to have something to do with loading images (e.g: adobe.com stops loading when "wwwimages.adobe.com" is being loaded. imdb.com, on the other hand, seems to load images very slowly and not all of them).
    Safe-mode. disabling add-ons, clearing cache and cookies and checking for malware doesn't help.

  • IMac 3GB 4GB RAM and Leopard

    My iMac, (24" late 2006) can be fitted with 4GB of RAM but it will use only 3GB.
    Will it use the full 4GB when I upgrade to Leopard?
    i.e. is this 3GB restriction a limitation of Tiger or is it a hardware limitation?

    BTW, 4GB is *800 times larger* than my first hard drive
    The good old days, I donated my first Mac to the elementry school when I bought my second Mac a $2300 1995
    Uh, yep, that's the good old days -- but I was talkin' about the BAD old days, as in: DEC PDP-8, Data General Nova, HP 2114A.
    Of course, the hard drive I was referring to wasn't actually mine, it belonged to my employer. It was an HP 7900A: 4.9 MB @ USD $9975.00 ...that's 1971 dollars ...
