How to free up memory

Hello

Forgive me, but I'm so inexperienced with the Mac and I have a really basic question. I am trying to install OS X Lion mountain and get a message that it needs at least 2 GB of memory. How do I "free" memory space so that I can download?

Thank you!

This means that a MINIMUM of 2 GB must be installed! a 2008 iMac can accommodate up to 6GB OWC (www.macsales.com) made a kit. Incidentally the ML is not generally available, the latest version of Mac OS X's El Capitan 10.11.1.

  • How to free the memory consumed by the Essvr.exe

    Hello
    Whenever we start a request will start a process called ESSVR.exe in the background and his memory, consumption will increase as and when we run the calculations. But after the calculation is performed should not reduce the memory consumption.
    Whats happening is that sometimes the calculation gets hanged and when I kill the process and start it again, it is run after a couple of times the calculation again gets hung, is possible to free this memory consumed by the process through calc only, script commands so that every time when a calc script finish the memory is released. We use essbase 9.3.1.

    When an application is started, the first thing it does is enter memory equal to what is defined as the key cache. This memory is never released until the application is stopped. He leaves also consumes memory for the data cache as she needs until he reached what is defined for this cache. Yet once that memory is not released until the termination of the application. In addition, additional memory can be consumed for different things while the demand is increasing. For example dynamic cache calculator will use memory during the execution of a calc, each user to make recovery uses a little memory (which can add up with many users). ASO data load buffers use memory, kinds of report and recoveries, etc., you get the picture. All these resources are released when the application terminates. (or should be, there have been cases of memory leak in some versions)

  • How to free the memory after the end VI

    The data is collected once in a loop and added to a table of data. The collection was completed after the loop ends and a data table was built. In the end, the data has been written to a file. The program ended naturally. I guess that all the variables are erased from memory after the end, but it wasn't. If I run the program twice without closing, I have a set of newly collected data added to the 'old', which was created in my last run. A third series has been added if I run it once more.

    I just want to keep the last function as my data and I don't want to close the program to set all my settings to similar races. How to do?

    A sample file is attached.

    Thank you.

    You need to wire a constant empty table to the Terminal (lower bound) of the feedback node initializer.

  • Accumulation of memory in InDesign: how to free the memory?

    Hey guys,.

    I'm fairly new to InDesign extendscript and quickly ran into a problem that I can't solve everyday.

    I'm working on a flash (version with adobe extension builder) Panel which, among other things, automatically the thumbnails page on exports, adds some data and so on... during treatment of pages (true magazine with a lot of content), the memory raises up to 1.5 GB and InDesign crashes. When I try less grave InDesign pages not down, even after the completed export script, InDesign uses still some 1 GB of memory.

    To get initially page thumbnails, I use the built-in function Document.fileExport (Menu-> export (JPEG)).

    I absolutely do not understand the tricky part is, if I call with window options (Document.fileExport: showingOptions = true), the memory instantly drops about 10 MB. So I 'bypassed' this problem by exporting pages in bursts (10 pages at the time) and indicating the options for the export of 10 pages. This way memory relies for 10 pages, then descends and accumulates again. But never up to 1.5 GB of crash InDesign.

    As you can guess, this workaround is real pain in the anus, because export is automated is no longer and need operator / monkey push-button every 5 minutes or up to prevent InDesign crashing. (reminds me of the TV series LOST )

    I tried to call $. gc(), but absolutely nothing happened. Even when I created the button dedicated with single purpose: call $. gc() and kept pushing for 10 minutes after export was over - nothing happened, the memory was still upstairs.

    I just reopen the old project (abandoned due to the accumulation of memory) and was really surprised that he was suddenly works fine. I did a little googling and discovered that there was an update of InDesign in August 2010 that included graphics export patches.

    So, if anyone google this thread, it is more relevant if you update IDS 2010/10.

    Way to go Adobe!

    Thank you, Peter

    Amy, I reached my goal, see the results:

    1. Firefox/Safari (Flash plugin version 12.0.0.77): Insider with 9 MB, 135 MB back and trimmed to 17 MB.
    2. Google Chrome (PepperFlash version 12.0.0.70): initiated with 12 MB, goes up to 132 MB and trimmed to 17 MB.
    3. Flash Player (Adobe CS5/Release/FlashPlayer.exe version 10-12 without running CS5): initiated with 6 MB, 185Mb back and filled with 185Mb.

    I realized something, with FileReferenceList.fileList if I so FileReferenceList.fileList [5] = null; (when the "sixth" file no longer serves) Flash memory immediately release this specific FileReference.

    Has worked on all the desktop computer / Plugins / PepperFlash.

  • How to take movies on my macbook air to free up memory and still access those I downloaded from iTunes?

    I want to free up the memory on my macbook air and have 65 GB of movies hogging the space. I don't want to lose them forever if you want to know how I can free up memory and again back to the film at some point in the future.

    If they were purchased through iTunes, you can download again them at any time.

    However, there is no way to stream movies, so you have to download the entire file again for a movie.

    Open iTunes > iTunes Store > purchased (on the right side of the window) > movies.

    Make sure that the sort is set to "Not in my library" If you try to redownload something that has been removed from the computer.

  • How to free up RAM memory in my macbook pro

    Hello

    How to free up RAM memory in my macbook pro

    In the current Mac OS x versions, Apple realized that the FREE RAM is not useful for anything whatsoever. What is needed is "instantly available RAM", and they began to be implemented in a number of ways. Free-ing RAM is no longer applicable.

    Some of your RAM may be used by an element called cache. These are copies of files read previously, in the hope that you will need to see again them soon. This RAM is said to be immediately available when an Application makes a request for the new RAM. In addition, little RAM is compressed. If it is referenced, Mac OS X can decompress a lot faster than to a new reading of the disc.

    The important point to look at the activity monitor is graphics memory. If it is not green, you may have to look more carefully at how you use your Mac and its RAM. The telltale signs that you need more are using PageOuts or Swap (but these counters start at zero at the start, so if you have worked for days, some will have invariably been used).

  • IPhoto deleting turned off my laptop computer to free up memory

    Help please - I transferred all my photos currently pictured on a stand alone disc

    I would also like to keep my last holiday pictures to my lap top and remove the other albums to release the memory. Pressed delete album on the albums up to 20, but the "amount of memory left has not changed.

    Anyone has any idea why?

    Second question, if I take the apple supply and store all my photos in the cloud, this will free up memory on my laptop?

    Cheers - MP

    To get help, that you must first provide details since we cannot see your computer - you posted in iPhoto for Mac forum but about pictures for Mac and give no idea what OS you have - what version of the operating system you have and what software photos do you use (name and version)

    In Photos or iPhoto cut an album recorded without space like albums aren't a place, but simply a way to display your photos and albums to take no space - and once again withou knowing what software you have in fact we cannot tell you precisely how to remove photos from your Mac

    If you're using iPhoto where you posted then iCloud library isn't an option - if you use instead of Photos, so is and if you set it to use optimized photos it will be disc space required on your laptop, but even once unless we have details we cannot tell you all you need to know

  • How to reduce the memory usage when loading bitmaps from the library?

    When I use BitmapData.loadBitmap () to load an image in the library, then attachBitmap() to add it to a MovieClip it takes a lot more memory instead of just to have the same image inside a MovieClip statically in a frame in the timeline.

    The dispose() function not only deletes the BitmapData object but also destroys the bitmap previously attached inside the MovieClip, so it cannot be used to free the memory.

    Is - this how it is supposed to be or there at - it another way to dynamically attach bitmaps with comparable rightly memory use have them on stage?

    You can do the same thing with movieclips: create a bitmapdata instance and use the draw() method to overlay as needed.
