iMac, can I mix maps memory 2 G and 4 G

I've just updated to El Capitan on an iMac with 4 GB of memory. Now, I want to add memory, because it is really slow. There are 2 empty slots (0/Dimm0 and Bank 1/Dimm0 Bank) and 2G cards in the other 2. Can I get 4 2 cards to the homes empty, or is - this bad mix sizes? If I can mix, no matter who go in what locations?

Yes, you can use 4 x 2 to expand the memory.

It's OK if you re-arrange-the as Chair of music, however, save time, simply insert these 4 x 2 in the existing empty slots, then

you're ready to go.

    You are confused of RAM and disk space available.

    RAM stores information temporarily while the Mac is enabled and the application is reached. RAM replacement has no effect on the long term of your information storage.

    The hard drive is where your information is stored in the long term. If you replace your hard drive, you need restore the information from a backup.

    FYI, for your iMac, the maximum RAM is only 6 GB.

  • Help - my virtual memory is full and I can't fix it

    Hello

    Last week my mac started saying "the applications memory is full" and detective work showed me my virtual memory is full.

    I have used Clean my Mac 3, but that did not help (he removed a lot of junk to computer, but still the same problem of memory)

    I'm not technical interest but have tried some things and not having any success.

    Any tips?

    Basically, he did my livelihood Imac all gel, so it becomes impossible to work. (Can't even type this her - do for my laptop).

    I'd just better take it to a genius bar or it's something that I can solve with the help of you good people?

    You must free up space, delete apps that you don't use

    delete old photos, perhaps after saving them remove old video clip...

  • How can I mix two video clips where they join together in a movie?

    Hello wonderful movie spirits, decision-making

    I'm working with Adobe first 6 on a Windows 7 computer.

    How can I mix two video clips where they join together in a movie?

    I know how to place two or more video clips together in the same movie, but how can I give them a bit of a mixture of just where they join?

    I have a PDF manual and the instructions of the built-in web browser.  In the instruction manual to the "Chapter 7: layering and Compositing", he talks about the transparency of a video sequence and I understand that... but I don't want to do one or the other video clip transparent anywhere except where the two video clips are joining with maybe a bit of overlap.

    I would like to make a little blur right where the two videos are joining the middle... is it possible?

    Thank you

    Digi

    AHA that kind of mixture.

    6.5 have not used in a time loooooooong.

    It's so memory, hope I get this right.

    Together the two each other clip

    Make a hidden in Photoshop and overlay it on the two clips.

    Go to the transparency settings and the value of the top 2 video clip touches Alpha.

    Screendump to mast:

    The right side is black just for the forum, but should be transparent.

  • How can implement you not with Tim Capsule and AirPort their simulation on the iMac?

    Hello

    How can implement you not with Time Capsule and AirPort their simulation on the iMac?

    I don't know what you're asking.

    AirPort Extreme is a wireless router.

    A Time Capsule airport is an AirPort Extreme with a built-in hard drive for data storage.

    An iMac is a Mac computer.

    An iMac is not a wireless router, so he is unable to perform the functions of a wireless router.

  • iMac to run out of memory system [Etrecheck report]

    I have an iMac 2013 end (27-inch, 3.2 GHz i5) with 24 GB RAM installed running OS X El Capitan 10.11.5). Whenever Safari is open, it slows down gradually until I get a message "your system is out of memory the application" and several applications have been suspended. I tried to reinstall the OS X without result.

    Once a report of Etrecheck indicates failure Drive with 19 errors, I contacted the Apple Support. The tech support guy was not familiar with Etrecheck, but don't think it was a defective drive. He had me DOWNLOAD & running Malwarebytes (did not find anything), create a Test user (which looked OK) and accompanied me through the removal of the caches in the library in my own user (which seemed to work for a while). He seemed anxious to finish my problem, so I let it go. Then he started to slow again. Subsequent reports of Etrecheck showed still drive failure but with only 2 to 5 errors. Now the drive seems fine.

    Safari seems to be the cause. I deleted several tabs and off most of the extensions, but it did not help.

    Here is the current Etrecheck report:

  • My iMac can boot from an external drive?

    Hello

    I have an iMac 21.5 "Mid 2010 which starts to show its age with slowness. However, I plan to upgrade the Basic 4 GB of Ram either 8 GB or 16 GB of Ram, depending on price... and my main question.  I know that the Mac came initially with a 500 GB hard drive and I would also like to upgrade to an SSD because they make a world of difference from what I've heard, but I don't have the level of skill tech to do the steps together 20-30. I wonder, as I have a 1 TB USB SSD externally, if I could install a new version of Mac OS X on the SSD USB and then set it as my boot drive and just keep still plugged. Would this work or startup disk must be internal rather than external via USB?

    Your iMac can be set to boot from an external drive. Just install OS X on the SSD and SSD drive as your boot disk in System-> startup disk Preferences.

  • iMac can't see SD cards

    My iMac can't see SD cards as before gradually.

    Disk utility cannot see the SD cards.

    All of my SD cards are good.  They can be read by other computers.

    Try a reboot.

    Make a backup using Time Machine or a cloning program, to ensure that data files can be recovered. Two backups are better than one.

    Try to set up another admin user account to see if the same problem persists. If back to my Mac is enabled in system preferences, the guest account will not work. The intention is to see if it is specific to an account or a system wide problem. This account can be deleted later.

    Isolate a problem by using a different user account

    If the problem is still there, try to start safe mode using your usual account.  Disconnect all devices except those necessary for the test. Shut down the computer and then put it up after a 10 second wait. Immediately after hearing the startup chime, hold down the SHIFT key and continue to hold it until the gray Apple icon and a progress bar appear. Startup is considerably slower than normal. This will reset some caches, forces a check for directory and disables all start-up and connection, among other things. When you restart normally, the initial restart may be slower than normal. If the system is operating normally, there may be 3rd party applications that pose a problem. Try to delete/disable the third-party applications after a reboot using the UN-Installer. For each disable/remove, you need to restart if you do them all at once.

  • How can I mix and match different amps and cabinets?

    I'm running Logic Pro and still have a problem with the amp Designer. I read in the world how it is easy to mix and match different amps, cabs and pickups but the drop down menus where I should be able to select them all are disabled. I can browse all presets of course, but I can't mix and match.

    I found some advanced tools in the preferences and activated all the boxes in there, just to see. The question remains the same.

    No idea how I could get these options enabled?

    No problem here. Once you select a different amp and Cabinet, you should see 'tailor-made' next to the model on the left.

    I don't think that the patches have nothing to do with him, but have you downloaded all the additional sounds, in particular "the guitar"?

    Hope that helps
