4.5 GB of RAM at start up?

I need a way to reduce RAM usage, please, even I prefer to rollback/downgrade to Mavericks, if possible.

Don't worry about the RAM usage. OS X is based on BSD UNIX. Most UNIX based systems will take all the RAM they can get to help enhance performance. If you're looking in Activity Monitor, the important measure to pay attention to is Memory Pressure. As long as that's green, you're doing fine.
As for the antivirus... honestly... just remove it. Don't waste the resources on it.
There are no known viruses in the wild that can infect OS X. There are adware, trojans, and other malware, but they generally require user intervention to install in the first place and most antivirus software won't catch them anyway.

  • After maxing out RAM, laptop starts fine, but OS won't start

    My laptop is a Toshiba Satellite C655D-S5057. I swapped out 2x2GB for 2x4 GB modules. The BIOS posts fine and I can enter setup. However, Windows will not start from the HDD. The laptop freezes on a black screen with a white cursor line in the upper lefthand corner (just prior to what would be the Windows screen). The cursor blink about twice and then freezes. Also, I cannot boot from my DVD-Rom either.
    It also freezes when I have just 1 x 4Gb in either slot.
    However, if I put 4GB in the bottom slot and a 2GB in the top slot, Windows starts normally.
    The BIOS is the latest version ( 1.8). I also disabled legacy USB support with no luck. I dropped HDD to be the second boot device, however, no luck there either.
    I am running with 6 GB since that allows it to start, but I'd rather use my pair of fours...

    what memory are you using?  You should always make sure the mfg (corasair, etc.) certifies that the memory you are planning in using has been tested and compatible with your computer.  You need ddr3-1066 but this does not tell you the timings.  that is where the mfg's come in.  Use the wrong timings and your lucky to get it even to boot.  Using mismatched is also not recommended as you will loose the dual channel feature and you might as well just put your 4gb kit back in as it will perform better than a mismatched 6gb kit.

  • Photoshop on 10.4.8 @70% RAM eventually starts halting delaying and lagging

    Ive got RAM in photoshop set to 70% the default.
    I have a QUAD with 4.5 GB RAM....
    I am only using PHOTOSHOP CS2 no other apps are launched.
    for the first few hours things are OK.
    then all of a sudden zooming takes time
    writing keywords is delayed
    then everything is delayed, almost halted
    this has been going on for months.
    This was a top of the line computer once and 10.4.8 is the latest OS right?
    I have reinstalled already did a clean install months back.
    Im sorry for this rage but this shouldnt be happening. I should be able to have atleast 3-4 apps going right?
    it creeps to a halt at 70...
    Does anyone have this problem with Photoshop?
    thank you

    Glenn, you don't sound rageful, although I for one wouldn't have put up with this for "several months".
    Sounds like a memory leak.
    That indicates a software problem, not necessarily a Quad problem.
    -Are you sure you don' t have other apps running in background?(Dashboard, iTunes, Safari, Mail,etc...)
    -Have you checked with Adobe support (they have great forums) for specific fixes for CS2?
    -You say "all of a sudden" things take time. Is that an accurate statement, or illustrative? Usually a slowdown like this creeps up on you (not an 'all-of-a-sudden' thing)
    -When you get this condition, a simple restart clears it, right?
    I may be wrong, but it sounds like a Photoshop thing.

  • Specifying start/end of "Save RAM Preview"?

    I save RAM previews to preview comps with real-time audio, since AE's RAM Preview lags on audio, preventing me from syncing video and audio.  When I save the RAM preview, it starts slightly after where I have it set in AE and ends much earlier.  How do I specify the RAM preview start/end parameters?

    You can specify beginning and end of the duration to be previewed by setting a work area.
    That doesn't necessarily seem relevant to your problem of lagging audio.
    If audio and video are out of synch, then please file a bug with details about version numbers of software, kinds of footage, et cetera. You can send bug reports to aebugs <at> adobe <dot> com.

  • Mac Pro 5.1 won't start single flashing SIL reapeats

    I have a Mac Pro 5.1 2010 quad core 3.2GHZ and 3GB original Apple installed RAM.  Problem is my Mac Pro no longer boots or gives the start up chime. The status indicator light blinks one short blink and repeats and the fans and hard drives spool up but that's it.  I've reseated the RAM chips as well as the processor and RAM daughter board with no change. I've also tried resetting the SMC using the power button method with no change.  I've ordered replacement RAM which I'll swap out once I get it, but if that doesn't work I'm running out of troubleshooting steps.  Anyone have any ideas?  I would really appreciate any assistance.  Thanks, Andy

    Thank you. That gave me the idea to get all of the RAM back in the the Mac. It powered up, oddly enough. I hope it's obvious, but I've already tried to turn it on with all of the RAM installed. At any rate, when it finally turned on, it was down from 32 GB to 28 GB. I thought this was an "aha" moment, so I turned it off and pulled out the two bad DIMMs, replaced with 2 new ones and it would not start. Now I thought I would reconfigure the RAM the way "it used to be" with the (4) Samsung DIMMs in slots 1 & 2 (on both risers A & B) and the IBM RAM in slots 3 & 4...
    When trying to get the Mac to power up previously I was trying various configs and ended up with: Riser A: IBM slots 1 & 2; Samsung slots 3 & 4; Riser B Samsung slots 1 & 2 and IBM slots 3 & 4. When it was down to 28 GB it was the IBM on Riser B/ 3 & 4 that was down. Well, I went back to this exact config and it powered up after "playing with" the power button...holding it in for various lengths of time until it responded. It did respond after 1-2 tries of say, one 4 sec hold, then another. It did all of this while initially giving me the repetitive pattern of the white light blinking every 4 secs (indicating there was insufficient RAM to start-up). When it did finally start up, it was back up to 32 GB. This is strange because I did nothing to the RAM but pull it out and put it back in and reverted to an older configuration as noted above (which recently resulted in 28 GB of RAM). Thoughts?

  • Ram Preview Issue with Yosemite

    Hi, I have updated to OS X Yosemite, I am using AE 13.1.1.3, and now I am having an issue with RAM-Preview that makes working with AE problematic: When I start the Preview by hitting "0" on the Numpad the Ram Preview starts, but I am not able to stop it anymore until it has rendered to the end of the work area.
    It is also strange that I am able to move keyframes while it renders.
    The Shift-Ram Preview is also affected by this bug.

    There is a known bug with Yosemite and the RAM preview, but your issue sounds different. Anyway, see the known issues here: After Effects good to go with Mac OSX v10.10 (Yosemite)

  • Started with OS 9 and Cube lost its chime

    G4 Cube, OS 10.4.11 and 9.2.2 installed, 1 gb RAM.
    Started it with OS 9 for the first time in a while, and ever since then it has no startup chime.
    Not a terrible loss, but all the same, I generally expect it on startup, so I'd like it back. Anyone got ideas on why it's gone, and how to get it again?
    Thanks

  • Fan just runs at start up

    mac pro (about 6 years old)..on latest OS that it can take.  at start up the fan just runs and the light on the front just blinks..nothing on monitor

    the light on the front just blinks..
    That is an indication that there is not enough good RAM to start up.
    Note that in older Mac Pro with memory in pairs, if one member of a pair is not working, both are unusable. So in some cases, mixing and matching may produce a pair that works.

  • My MacBook Pro froze and started a soft slow beeping.  When I restarted it the screen is blank.

    When I went to wake my MacBook Pro, it was frozen and there was a soft, slow beeping.  I restarted it, but it goes to a blank screen.  Help, please.

    If you get either Beeping of Flashing at Starup, that indicates there is not enough good RAM to start up. Some of your RAM may be dislodged, but more likely it has failed.

  • 64GB+ RAM support: OS X v10.8.2 Supplemental Update 1.0

    OS X v10.8.2 Supplemental Update 1.0, a minor software update bringing a handful of fixes to the latest version of OS X Mountain Lion. 
    The OS X v10.8.2 Supplemental Update is recommended for all users running OS X Mountain Lion v10.8.2 and includes the following fixes:
    - Resolves an issue that may cause certain Japanese characters to appear incorrectly in Mail
    - Allows Safari to access secure sites when parental controls are enabled
    - Addresses an issue that may prevent systems with more than 64 GB of RAM from starting up
    Not on http://support.apple.com/downloads/ yet.

    The supplemental update did address the 'slow' Time Machine backups under 10.7.5 - if this is your first backup, and depending on how much data you are backing up, I would guess that it could take 6-9 hours, but certainly not 2 (or 99) days. If it seems that the backup is 'hung' just stop it, reformat the external drive, and try again. For some great Time Machine troubleshooting tips, see http://pondini.org/TM/Troubleshooting.html.
    Good luck,

  • What does RAM do?

    What does RAM do? And for example I have 4GB's of RAM in my computer but I believe its upgradable to 8GB, if I upgraded it to 6GB or 8GB what would I notice changed about it from the current 4GB RAM?
    Thank you

    RAM (Random Access Memory) is the equivalant of human 'short term' memory - it stores information that's currently being used. The hard drive of the computer is the equivalent of human 'long term' memory - it holds all the information you're not currently using, such as files you've saved.
    When your computer runs out of RAM it starts to use the hard drive instead. The problem here is that the speed information can be stored onto the hard drive is far slower than the speed RAM operates at, so it slows your computer down fairly dramatically.
    Having more RAM lets you do more things at once, for example having many applications open at the same time. Whether you would benefit from more RAM or not depends on how you use your computer, if you multitask a lot you'd probably notice a difference. The following article shows how to see your RAM use:
    http://support.apple.com/kb/ht1342
    If you've not got much green 'free' memory left and/or a large number of page outs you could probably do with adding more

  • Best Amount Of RAM For Web / Media Designer?

    Hello Everyone,
    First post and jumping right in.
    I'm moving to a MAC permanently and this will be my first purchase (iMac 27" Quad Core). Can anyone tell me the most suitable RAM upgrade I'll be needing? My budget really doesn't allow for the 16Gig right now unless it's really needed.
    I do run mostly the Adobe CS line sometimes 3-5 programs at once (Photoshop - Dreamweaver - and most memory hogging-ly Premiere). Soon I will be getting into Final Cut Pro.
    Needless to say aside from a myriad of other issues performance and lag-time is why I'm jumping ship from PC.
    Does everyone think I'll be pretty satisfied going with 8Gig of RAM to start or given the above info am I wasting time not going straight for the 16Gig?
    I've spoken with a few designers and they've told me while the Mac Pro is incredible - it's overkill for what I need storage and ...well...everything else wise and the common saying has been - get the iMac and upgrade the ram.
    So I humbly ask you experts. To summarize my wordiness above
    8 or 16? What are your thoughts as well as any other great add ons that could be of use to a designer with a large check from a recent project burning a hole right through his pocket?!
    =)

    I would recommend adding 2 x 4 GB for a total of 12 GB; you can then see if that will be enough. Please note: there have been posts here regarding problems of the new iMacs when adding third party RAM for a total of 16 GB; there have been no problems reported if the 16 GB is OEM RAM (such as Samsung or Hynix, which is what Apple has been using). So, if you intend to keep the original 2 x 2 GB, then I'd suggest adding 8 GB.
    That is what I did; I do a fair amount of video editing and the iMac is doing just fine with 12 GB. Also, iMacs are quite finicky about their RAM - do not buy any brand "value" RAM - stick with quality RAM from reputable vendors with lifetime warranties, such as OWC (macsales.com) or Crucial (or Samsung which will be more expensive).

  • Black screen after upgrading ram (macbook pro late 2007)

    Dear Community,
    I am willing to donate 100 USD to anyone who is willing/able to provide concrete resolution to this problem.
    I am a professional freelance videoeditor and my job is currently stucked due to inability to boot my macbook pro again.
    After upgrading the RAM of my MBP (late 2007 model, 17'' display, Intel 2.4GHz Dual Core processor), the screen went black and the system did not boot any more.
    I tried to replace the orginal 2 x 1GB DDR2 533 CL=5 SODIMM (single rank) with 2  X 2GB DDR2 800 CL=6 SODIMM (dual ranks).
    After the memory upgrade, the system was restarted, I heard a short beep, but the macbook showed a black screen instead of booting properly. The mainboard was powered, the fan was moving. I saw a green led turned on on the center of one side of the macbook.
    I tried to mount the previuos 2 x 1GB DRAM SODIMMs, but nothing happened. The system keeps not booting even with the original memory.
    I tried already several procedures suggested by the user manual, related to SMC Intel controller reset (with battery and without battery and charger), but those were not effective in restoring the normal operation of the macbook. The system keeps not booting with exactly similar issues (black screen, fan on, short beep after power-on, green LED on).
    I also tried to swap the memory DIMMs into the memory sockets. I tried to use a different combination with 1 NEW 2GB and 1 OLD 1GB  DIMM. But the problem is still there with similar sympthoms.
    DOES ANYONE HAVE ANY CLUE OF HOW TO SOLVE THIS?

    My best guess is that you have fried the RAM with static electricity charged up in your body. According to OGELTHORPE a beep on startup is because of no RAM, if when installing you did not do it correctly, you could have fried the RAM, which then your mac will not recognize it. The same with the old RAM, if you tried to re-install it and didn't pull up your sleeve and rest your arm on the inside of the chassis, then it is fried, or if you didn't wear an ESD band and connect it to the the chassis, then it is fried.
    Seen as though you can't startup your mac, I can't say to do an AHT, buy some new ram, and start with the lowest one you can, so its cheap for ya use a different company incase is that;) Crucial.com is really good, I got an 8gb upgrade from 2gb. Let me tell you, it's great!
    Reply back;)

  • Satellite l25-s1194 start up problem

    Push the power button and hd light lights up briefly, you can hear the hd start and then the hd light goes out. The cooling fan starts and runs and the power light and battery lights are on. But that's it. If you let it stay on the cooling fan speeds up now and then but that's it. I know its old but I just need to retrieve some files and emails, so if I can get it going just enough to retrieve things I'll replace it. Any help would be appreciated. Thanks 

    Satellite L25-S1194
    1) Try removing only the battery, leave the AC plugged in, power on.
    2) Try unplugging the AC, leave the battery in, power on.
    3) Try unplugging AC, remove the battery, remove both RAM modules, replace one RAM module in a different spot, replace battery & AC, power on. Repeat this process until you have tried each RAM module alone in each slot. See the installing/removing RAM directions starting on page 54 of your Satellite® L20/L25 Series User’s Guide. 
    4) If none of the above works it could be a corrupt BIOS.

    5) As I'm sure your system is off warranty, perhaps you could consider paying a professional for a diagnostic:
