Does turning off universal access increase computer speed

Does it increase performance if you turn everything off?

No.
Obviously, every process uses some resources, but look in Activity Monitor. The system and core apps are probably using around 5% of your CPU. Unless you need every last cycle of power out of that thing for that protein folding model work, turning stuff off is not going to provide any advantage in speed.

  • How can I turn off Universal Access?

    If my mouse cursor moves across the screen (without me moving it) to the dialog box one more time, I'm going to scream.
    Every time I uncheck "Enable Access for Assistive Devices" in the Universal Access Preference Pane, it becomes checked again after logging out or restarting.

    Hello,
    Try this: Locate this file: com.apple.universalaccess.plist
    It's here: MacintoshHD/Users/YourName/Library/Preferences
    Open the Preferences folder. Locate that file and drag it to the Trash. Empty the Trash and reboot. Your MBP will create a new preference file for you.
    Sometimes preference files can become corrupted... hopefully this will take care of it.
    Post back if you need more help,

    Captions are not respected when turned off under Accessibility and still appear in the native player, how do I turn of captions for the native player?

    Restart your computer while holding down left mouse key. That will eject the CD and your Mac will start as normal.

  • Is it possible to turn off my access to the exchange server?

    I'm feuding with the ITS department at the moment. They claim they don't want to support my iPhone, they only want us to use the crappy Blackberries they gave everyone. I had to set up my own iPhone - Exchange connection, and it has all worked fine up to now, but about 3 hours ago my entire connection to the Exchange Server was killed. I get no email, no contacts, no calendar, nothing. My fellow iPhone users (3 in my office) aren't getting email either.
    I suspect that the evil ITS administrator has turned off access to iPhones, but nobody believes me. Is that possible? Is there any way around it? I don't want to have to carry two phones.
    The ITS administrator told my boss this morning (shortly before i got disconnected) that Microsoft might be "turning off" the access to iPhones from Exchange servers. That didn't make sense to me, because Apple is paying MS for the right to use Exchange, right? Also, I googled and couldn't find anything about that kind of an announcement. Has anyone else had issues today?

    gamecoug,
    Administrators of an Exchange server can block access for ActiveSync devices server wide, account specific, or even device specific.
    In addition using ActiveSync they can specify security policies for connected phones. The iPhone supports remote wipe as well.
    Hope this helps,

  • Turn off remote access to g1100?

    I have recently signed up for fios and have been supplied with a verizon g1100 wireless router.  Both the fios service and the router are working without problems.  However, I see that the router reports its internal settings, including my wireless password, to verizon, because I can view them when I sign in to my verizon account.  Also, the user guide for the router says (p.14, line 6) "Firmware updates are performed automatically by verizon".  I can understand the convenience of these arrangements for verizon and some users, but I also see them as a potential security risk.   Is there a way that I can forgo the convenience and turn off external access to the g1100?   I know that I can replace the verizon router with one of my own, but it seems otherwise satisfactory, so I would like to keep using it if I can do so more securely.

    Apologies for the trouble your having, but there is really no other option to close the port off. It's hard-coded into the router. Just in my opnion in the long run, it would be best if you used your own router. I've switched out the Verizon router with my own pfSense router, and have never been more happy. The level of control you gain over your network is excellent when using your own router.I agree with you. How can the OP bridge that vdsl modem OR use their own vdsl modem?I see no mention of bridging a vdsl modem or using his own. What's being stated is for the op to use his own router instead of the g1100 that is behind the verizon vdsl modem.  I guess the op would like to use the g1100 as it's a better modem but can't disable 4321.  Of course he could just cascade  his own router off the g1100 and have his on-premise network off his personal router where 4321 is blocked, leaving the g1100 in place for less sensitive access.Could also do the reverse.  Connect your own router to the vdsl modem blocking 4321 and then cascade the g1100 off off of it.

  • Does turning off energy saver include never letting the display to sleep? A warning alerts me that its life might shorten... Thanks!

    Does turning off energy saver include never letting the display to sleep? A warning alerts me that its life might shorten... Thanks!
    (I'm doing this for the recalibrating of the battery etc...)

    It would shorten it's life if you leave it on year 'round. For the amount of time to calibrate the battery won't hurt it.

  • Monitor turns off to sleep but computer stays on???

    Monitor turns off to sleep but computer stays on???
    Any clues why? I can only shut-down and it gets annoying because I like to be working in less than a minute after powering up. Any things to look for to help?

    Thanks,
    don't know why it'd matter if I had a warranty or not since the function
    in question is apart of what I'm supposed to be getting w/ cost of computer.
    Time to load the overpriced 1 ton computer into the car and demand they fix it at the apple store. This is absurd since I originally bought this computer for music creating and it's the most unreliable computer EVER as far as stability for music. My audiophile records for like 10 sec. before the sound cuts out, everytime, but of course that's not apple's fault.
    Never buying apple again. This is straw that broke the camels back. Anyone wanna trade a pc for my G5?
    Sorry for the venting but this is where I draw the line!
    Thanks,

  • When I turn off the printer my computer locks up. HP Desktop.Photosmart D7360, Windows 7

    When I turn off my printer the computer locks up.  HP Desktop computer.  Windows 7.  Photosmart D7360.
    I have reinstalled the drivers.
    This question was solved.
    View Solution.

    Have you tried a different usb cable? It could be that the usb cable is grounding out which could be a short in the usb cable, or the port on the printer. Although it is also possible that it is the USB controller on your computer's motherboard so if trying a different cable doesn't fix it try it with another computer if at all possible. If the other computer doesn't have any problems then it is the HP desktop. At that point you're out of my realm of expertise friend . (In other words if this doesn't work, try your luck on the desktop forums or by calling 1-800-474-6836)
    Hope this helps!
    If I have solved your issue, please feel free to provide kudos and make sure you mark this thread as solution provided!

  • Does turning off modules speed up Lightroom 4?

    Hi All,
    It seems that in Lightroom 4 you have the ability to turn off individual modules by right clicking on them and unchecking whichever ones you don't use.  I'm wondering if when modules are unchecked, does that increase the speed or performance of the system?
    I recently upgraded to LR4 from 3 and definitely experienced a major slow down.  That being said, when I uncheck everything except the development module, the sluggishness completely disappears.  Is turning individual modules off actually helping performance? Can anyone else confirm this?  I've posted on a few other forums and haven't had a great response.  Thanks!

    Actually, in another thread this topic came up and I'll post my results below...
    The posts above are correct, simply "right clicking to turn off the modules from the title bar does not disable them.
    I have had significant performance gains by actually removing the modules altogether from the Lightroom program folder.
    Your mileage will vary.
    My original posts come from this thread : http://gsfn.us/t/2qqr8
    I've made slight edits for context.
    When I removed the modules, I started from scratch.
    I simply uninstalled LR4.3, defragged, reinstalled, updated, moved the modules i dont use, rebooted.
    I then used this link for the How To : http://www.slrlounge.com/boost-lightroom-4-performance-by-hacking-the-lightroom-modules-li ghtroom-4-workflow-system-dvd
    It's insanely easy.
    I followed the standard Adobe recommendations for lightroom that you can search for in "help".
    I started Lightroom with one of my (large) existing lcat files (11k images) and regenerated absolutely everything at 1:1.
    Ate dinner, played the Xbox, ignored the phone... had family time for a while.
    right now,
    it opens bullet fast into library.
    it's 10 seconds to move from library to develop. film strip scrolls bullet fast- but at super low Rez and takes 3 seconds to load the "highrez thumbs" - once I stop moving the strip (12 thumbs wide)
    When an image is clicked they open to "fit" within 3 seconds. Choose 1:1 and its 5 seconds.
    switch to library again and it's 1-2 seconds and a redraw of the image - filmstrip unchanged.
    choose an image at 1:1 and its a 3 second wait
    "Fit" is immediate. awesome
    these times flex a second either way depending on image content.
    scroll film strip and it behaves the same as above - but not jerky like it used to be (up till today's efforts).
    LR4 is way faster than LR3 like this.
    ==============
    --- I then read another person's post relating to my earlier posts and decided to do a test :
    ==============
    put modules back.
    20 seconds to start.
    I don't change the image shown.
    change to develop 30 seconds
    5 seconds to "refresh" same image same setting of "fit"
    change to 1:1 6 seconds
    lower to fit 2 seconds
    back to 1:1 2 seconds
    film strip jerky on develop
    thumbnail refresh same speed
    change to library - 3 seconds
    I'm still in 1:1
    film strip "less jerky" - only a slight lag
    3 seconds to load a new image as 1:1
    1 second to change to "fit"
    1 second back to 1:1
    with the one main image chosen in library, mouse wheel scroll is pretty darned quick, low Rez "fit" with 1 second refresh when you finish moving
    10 seconds to go back to develop in "fit"
    5-6 seconds for subsequent photo choices in fit
    1:1 is ten seconds
    scrolling the 1:1 is so jerky you have to use the mouse "hand"
    exit
    move - book, layout, print, slideshow, web
    delete win prefetch references for a clean start, reboot.
    wait for windows to realize its a computer and settle down.
    start Lightroom, same lcat.
    it remembers I was in develop and reopened in 5 seconds with a "fit" image
    cool actually - program loads and displays image all in 5 seconds, in develop.
    change to 1:1 2 seconds
    can actually scroll 1:1 with mouse only small lag
    film strip back to new normal (fast and smooth)
    change to library immediate
    back to develop 1 second
    new image 2 seconds on fit
    1 second to 1:1
    new image 1:1 2 seconds
    so yeah
    module disable worked for me
    my pickle?
    I have to test each one at a time to point adobe as to which is the issue...
    *sigh*

  • Does turning off wireless feature inactivate the firewall?

    My goal is to insert a hardware firewall between my modem and PPC Mac computer, and accordingly, plan to use the Apple Airport Extreme (AE) base station router for this purpose.  Since I don't really need the wireless feature at this time, I plan to turn off Wi-fi on AE.  Will doing so also turn off or diminish the WPA/WPA2 & WEP security firewall features of AE, or will they still work as expected with my wired internet connection?

    Wireless security is not really referred to as a "firewall" in the strict sense of the word. Wireless security, or encryption, is used on your "local" network to prevent unauthorized computers from connecting to your local network.
    A firewall is special software that protects all devices on your local network from devices on the Internet.  The AirPort Extreme uses a very effective NAT firewall.
    If you have the AirPort Extreme connected to a simple modem, the NAT firewall is automatically enabled.

  • Does turning off DHCP remove option to Share Hardisk over WAN?

    I'm a recent Apple convert. I have a new Macbook and have downloaded all recent updates.
    I just integrated the Airport Extreme Base Station into my current home network. I have DHCP turned OFF in the AP because I am running a netgear router in my basement that is already connected to my Cable Modem. It needs to stay in the loop because I am using it to feed my XBox360, due to the issues related the Base station/360 interaction.
    Here is my question... Does having DHCP turned off in the AP, remove the checkbox option in the "Disks" section of Airport Utility toolbar to "Share disks over Ethernet WAN port"? Its MISSING completely. I've seen many instructions that reference that phrase, but the only checkbox I have on that screen is one for using Bonjour. I want to connect a usb drive so I can have a central storage so my wife and I can share itunes/photos/documents. So could it be that option disappeared due to turning off DHCP or is there some other issue?

    If you want to share your disks over WAN then you need to do the following:
    1. Assign a manual IP address for your AirPort. You can do this by running AirPort Utility and under Internet you need to change Configure IPv4 from Using DHCP to Manually.
    2. You need to port forward TCP port 548 on your main router to the IP address you assigned your AirPort. After doing this you will be able to access your AirPort disks by going to Finder, Connect to Server, and entering afp://<yourgatewayipaddress> You can find your gateway IP address by going to www.whatismyipaddress.com while on your home network.

  • Does turning off email delivery also turn off text delivery?

    I just got an 8330 when my work switched to Sprint. I am on vacation for the next two weeks and would like to turn off my work email delivery. It comes through a Microsoft Exchange server. I also have two AOL personal accounts on the phone. If I select "No" for "send email to handheld," will that stop delivery of all my email accounts or will AOL messages still be received? I have separate icons for each of those accounts.
    In addition, I do not want to stop delivery of text messages. I have them separate from email right now. Will doing the above stop delivery of texts? 
    I looked to see if this had been answered before, but did not find it. Sorry if I missed it. Thanks for any help you can offer.

    HI and Welcome to the Forums!
    For your work emails, I suggest you talk to your BES admins about what to do...they are in control of that component.
    For the personal emails, the setting to NO will accomplish what you desire...it does exactly as it states (Send Email To HH = NO). You have to set that for each account.
    None of this affects Text Messaging...those are completely separate.
    Occam's Razor nearly always applies when troubleshooting technology issues!
