I have an Intel Core I7 iMac with an SSD. Does TRIM run on SSDs on iMacs? I was recently told it did not run on OSX, which is a bit alarming.

I have an Intel Core I7 iMac with an SSD. Does TRIM run on SSDs on iMacs? I was recently told it did not run  under OSX, which is a bit alarming.

TRIM is supported on Apple-branded SSDs, but not third-party aftermarked SSDs.

  • Adobe Priemere Elements Quits Unexpectedly all the time (using Intel Core 2 Dou with 2.0 G of RAM)?

    Yes its the common probolem that people are having but no, I dont have the NVidia card I have a Intel Core 2 Dou with windows 7 and its 32 bit. Yes thats the main problem but theres also this problem were the footage from my video camera is purple???

    Hi,
    I was having massive stability problems myself until I followed some advice I received from the support team.
    Even pop up processes like Norton's, McAfee's and Screen savers would kill my conformed audio & confuse things.
    Now I too only have a 32 bit OS (Vista Premium Home) but have 3GB RAM - the most you can utilise in 32 bit OS - & two internal HD.
    The advice was to save aside my raw media, then completely delete PRE 8 using Windows Add & Delete Programs.
    Next too I deleted all the directories it was using & also cleaned up various system deitrous using CS3CLEAN SCRIPT (Google for it)
    selecting Level 4 to clean the registry too - downloaded from the Adobe resource of course rather than anyone else.
    I then did a DFRAG on both C: & D: drives and a general file cleanup making sure that there was 25GB of swap space on C drive.
    This took a day and a bit.
    I then reinstalled everything and, this time, when I started a New Project I first of all set up scratch disks for every sort of cache it needs on my D: drive.
    It seems that this means its temporary files can be read and written efficiently without compteing with the processes competing for swap space.
    I still have problems with sustaining conformed audio but I will make a separate post about that in a minute.
    The good news is that the continual crashes and snail-paced user interface responsiveness is cured for now!
    Hope others out there can benefit from this post. Perhaps a future edition of PRE could notice at installation that you have an internal D drive & use it.

    Hi,
    This is the compatibility list
    http://www.apple.com/osx/specs/
    if your iMac is mid2007 or newer - yes.
    You will need to upgrade to 10.6 (Snow Leopard) first buy DVD from online apple store
    Then to 10.7 Lion - buy and download via Store App included in SL
    and then 10.8 Mountain Lion upgrade the same steps as Lion

    I tried adding more ram but the Mac would't even boot with 2x2GB installed. I figured that it was limited so I forgot about it. Wha's the advantage of adding it if it is not recognized?
    Chances are you either did not install or correctly or added the incorrect RAM.

    Where did it say that? If your computer meets the requirements you can install Snow Leopard and then install Lion via the Mac App store. They both cost $30

    According to the Lion webpage, you would need to add more RAM to your computer and check to make sure you have about 7GB of free hard drive space.

  • I have a Macbook Model No A1181 2.4 GHz intel core 2 Duo with 4 Gb Ram. Should I be able to instal Final Cut Pro 3.0.2 cos I'm having problems?

    I have a Macbook Model No A1181 2.4 GHz intel core 2 Duo with 4 Gb Ram. Should I be able to instal Final Cut Pro 3.0.2 cos I'm having problems? As I read it My machine should be able to run the software.
    Thanks in advance

    You are trying to use software that is over 10 years old. As I read it, FCP 3.0.2 required 10.1 or higher at the time, but as FCP is reliant on quicktime, which has been updated many, many times, I doubt that you will ever get it to work properly.

  • IMac 3.06 GHz Intel Core 2 Duo with 12gb of RAM running very very slow.

    My late 2010 iMac 3.06 GHz Intel Core 2 Duo with 12gb of ram is running very slow. It takes a very long for the computer to boot with the desktop taking ages to fully load. Applications are also taking an unholy amount of time to load with the spinning wheel always appearing through out use, and they often crash or don't respond and close during use. I'm talking applications like Word taking 3 minutes to load and getting the spinning wheel when font size is tried to be changed and crashing and closing if a large volume of text is attempted to be pasted into a document.The computer is also failing to shut down properly just staying on a blue screen. I recently wiped and completed a fresh install however the issues came back.
    As you can imagine after spending so much on the computer I'm not best pleased about these issue, I've spoken to the apple staff in my local store by they weren't very helpful and seemed to no little about computers and the so called "Genius" who I spoke to about my issue was a joke, repeating himself and talking utter rubbish, while I understand you need to look at a computer to get a real picture of an issue, some advice could of been provided. I haven't got time to take the computer to the store at the moment and get a technician to look a it, so I was wondering if anyone else had experienced these issues and knew what caused the fault, and that way if possible I can repair the issue myself.
    Thanks in advance for any help on the issue it’s much appreciated. At the moment I'm pretty close to ditching the thing and buying an Alienware!

  • Imac 2.16 GHz Intel Core 2 Duo with 2 GBs enough?

    Before I drop 5 bills of Logic 8, what kind of performance am I looking at with a Imac 2.16 GHz Intel Core 2 Duo with 2 gigs?

    Your machine is a whole bunch faster than the G5's most of us use, and 2 gigs should be fine. The only way you'll get a benefit from more than 2 gigs of ram is if you use other programs alongside Logic, or if you use lots of large EXS samples. Additional ram beyond 2 gig will not get you greater track count, more Space Designers (or any other plugins besides EXS) or lower latency. It will not get more instances or sample sizes for third party plugs used as AU within Logic. If you run third party plugs as rewire or standalone - separate from Logic - they will benefit from additional ram.
    I'm doing very well with a G5; additional drives and pci interface help alot. You should do even better with an Imac, although I don't know if it has a PCI slot.

  • I have a BookPro 15 2.2 GHz Intel Core 2 Duo with 4 GB Ram, that's more slow after updating to X Lion 10.7.5

    Hello
    I have a BookPro 15 2.2 GHz Intel Core 2 Duo with 4 GB Ram, that's more slow after updating to X Lion 10.7.5
    Is my hardware not good for this new OS ?
    Can I upgrade my computer to Mountain Lion OS  and make it faster ?

    Mountain Lion won't make it faster. It may not even be compatible.  Speed has a lot to do with what is installed, installation of utilities that actually slow you down, such as MacKeeper, or any cache cleaning softawre.  Installation of utilities that you don't need such as anti-virus or firewall software.  Peer2peer software.  Other devices sharing the same network can slow it down too, make sure your network is secure, and you know what is sharing the network.  Some websites may be slower on Safari, and an alternative browser* is needed.

  • What version of osx would give an Imac 24'' 2.3 ghz intel core 2 Duo, with 4gb of DDR2 SDRAM, the best performance? To do illustration and design jobs.

    What version of osx would give an Imac 24'' 2.3 ghz intel core 2 Duo, with 4gb of DDR2 SDRAM, the best performance? To do illustration and design jobs.
    Would the more recents os versions increase the overall performance? Is it worth it?

    Hello!
    Snow Leopard is what i am currently using. But i guess it does need some clean up and maybe a clean install to see if it gets faster.
    I believe 4gb is the limit for this model, although i've seen some with 6gb…
    Thank you for the help

  • MacBook Pro, OS 10.6.8/2.8 GHz/Intel Core 2 Duo/with 4 G memory and would like to hook up an external monitor.

    I have a MacBook Pro, OS 10.6.8/2.8 GHz/Intel Core 2 Duo/with 4 G memory and would like to add an external monitor.  I have the usual ports; 2 USBs, Ethernet, as well as a couple small ports that I do not know what they are for...  sorry .  First of all, is it possible to add a monitor or TV screen for a larger screen when using?  Secondly, if this can be done, what do I need to buy?
    Thanks so much!

    Yes, it should be possible. I think every MacBook Pro ever sold has some kind of port for an external monitor. You would have to nail down which kind of port your MBP has and where on your MBP it is located.
    Can you find the little "getting started" pamphlet, manual, or PDF that came with it? It should name the connectors.
    My guess? If the only ports you have besides USB and Ethernet are smaller than those, you could have a Mini DisplayPort.

  • Question: I want to update to the new LION OSX, but it says that I need to at least have an Intel Core 2 Duo. When I click "about this Mac," it says that I have a 2.16 Intel Core Duo. Is there a difference between the "Core 2 Duo" and the "Core Duo"?

    Well, my title basically asks the question that I am seeking an answer for. Im not sure what year my MB Pro is, and I cant exactly find it on the Apple site. Its a 2.16 Intel Core Duo, 2 GB 667 MHz DDR2 SDRAM. All I see (dating back to 2007,) is Intel Core 2 Duo on the apple site. Im pretty sure (but not 100% positive,) that my MB Pro is a late 2008/early 2009. Just trying to figure out if I can install LION OSX or not, since it requires atleast intel core 2 duo, and mine says I only have the intel core duo. Any help would be appreciated. Thanks!

    Core Duo is 32 bit processor and Core 2 Duo is 64 bit processor
    OS X Lion, will only on 64 bit Intel processor Mac's.
