I downloaded Downlite by mistake on my iMac 27 with mavericks. how do I remove it? and how dangerous is for the computer?

If you remove Downlite according to my instructions on that page, it's gone.
The trojan is distributed on illegal websites that traffic in pirated movies. If you, or anyone else who uses the computer, visit such sites and follow prompts to install software, you can expect much worse to happen in the future.

Welcome to the Apple Community.
Try deleting the problematic file (electing to remove original file if/when prompted) and then re-downloading the file from the iTunes store.
You can re-download content purchased from the iTunes store (availability varies depending on location) using the purchased option from the Quick Links section in the top right corner of the iTunes homepage in your iTunes application on your computer.
You can re-download content purchased from the iTunes store (availability varies depending on location) using the purchased option at the bottom of the screen of the iTunes app (or video app) on your iOS device.

Hi I have an Imac I5 21.5 inch.It was working perfectly.Then i didnt use that for about 2 months. Week ago when i want to start the Imac ,it didnt start.

But screen does not turn on.Please help me to rectify this problem.Best Regards. By the way I am an electronic technician.So if there are any technical things to be done, Pls let me know.I can do it my self.

Hey terremo,
Thanks for the question. From the information you provided, it sounds like the iMac is successfully turning on, however video is not displayed. These symptoms can usually be isolated further by the troubleshooting steps in this article:

I use iPhone 5s and iPad Air to take photos. They download automatically to my iMac. However, I often get dups, triplicates or more on the iMac. How can I stop this and how can I get rid of the extras that are already there?

Try upgrading your Mac to the newest version of OS X Mavericks, and try upgrading your iPhone and iPad to the newest version of iOS 7.
OS X Mavericks may not be in the Mac App Store by now, but you can find the newest version of Mavericks here at download.com: http://download.cnet.com/Apple-Mac-OS-X-Mavericks/3000-18513_4-76018588.html. Note: Download.com it a safe website to download free software.

Downloaded Mountain Lion on my iMac. Why is it so slow opening up from sleep and taking so long for the wireless mouse to engage?

Reinstalling Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

Running a mid 2009 iMac on 10.7.5, 3 gb memory, 320 gb hd.
Suddenly the computer stoped reading DVDs and the only time I can read a CD is if I restart. Quite often when I insert a CD it gets stuck and I cannot get it out until I restart and it shows up on the desktop where I can then eject it.
I have checked and double checked the finder prefs and all looks normal showing a check mark on CDs,DVDs etc. (the ones I want to show up on the desktop)
I have reset the PEAM, repaired permissions with both the disk utility on the computer and the disk utility when I start up in the Recovery Disk. I did notice that sometimes the permission repeat the same correction several times before it moves on, and sometimes it doesn’t. I have Windows installed on a partition but I keep it unmounted until it is needed for my wife’s work. The dock seems to be just fine and all the apps seems to run just fine. When I insert a photo CD iPhoto does not open but when I insert a music CD iTunes does open.
Also, most every time I open iPhoto it takes a long time(sometimes as long as 2 minutes) for it to load.
Sometimes my Mail (Mail 5.3) does not post new mail but most of the time it does.
Once and a while it seems like the computer slows way down but then it seems ok ten minutes later.
All of these ‘things’ seemed to have happen suddenly and I have not downloaded anything from the internet in some time.
Of course the warranty and extended warranty are both no longer in effect having had this computer for more than three years.
I am running Java and Adobe Player because some of the sites I go to a lot require both.

I believe that insufficient RAM may be the source of some of your problems. If you have a RAM of somewhere 4 to 8GB, you will experience smoother computing. 3GB doesn't seem right, so you might want to learn more by going to this site:
http://www.crucial.com/store/drammemory.aspx
I don't know what know what's happening with your optical drive, but it seems you use your drive quite a bit. In that case, look into a lens cleaner for your machine. It's inexpensive, works quite well.
I hope you'll post here with your results!

How can I use Aperture 3 on my new iMac with Maverick?

How can I use Aperture 3 on my new iMac with Maverick?

Do you own a copy of Aperture, perhaps bought for another Mac?
If you have not bought Aperture, you need to buy it from the AppStore.
But if you own Aperture and have it bought from the AppStore on another Mac, sign into theAppStore on your new iMac with the same AppleID you used to buy Aperure on your other Mac. Then look at the "Purchased" tab of he AppStore. It show Aperture, with the "Install" button to the right. Simply press the "Install" button and download it to your new iMac. Or if you have bought Aperture on a CD/DVD, run the installer from the CD/DVD on your new mac and immediately run software update to upgrade the Aperture 3. version to version that will run with Mavericks.

My 2010 iMac with Mavericks 10.9.2 is very slow. How do I fix?

I have tried the usual stuff: disk permissions repair, SMC reset, PRAM reset, dragging caches to trash, restarting computer, etc. My internet connection and speed is good. Computer is mid-2010 i3 iMac with 10.9.2 OS, 12GB RAM, and there is plenty of unused space on my HDD.
The computer is very slow to start applications and load web pages. I ran Etresoft as some have suggested and the report is below. Any help is appreciated. Thanks.

This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you boot, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, reboot as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

I reinstalled tiger on one iMac, but want to re-upgragde it to Lion. I don't have the discs anymore, but I installed Lion from the Mac App Store. Now that I'm back to 10.4, I don't have the App Store. I have a new iMac with Mavericks, but it won't let

I have a 2006 iMac that I've upgraded to each new os as they came out. I just wiped it (for the kids to use, I have a new iMac with Mavericks) and reintalled Tiger from the original discs. I want to get it back to Lion - which I purchased from the Mac App Store. But Tiger doesn't have the App Store and I don't have the discs anymore from the intermediate versions. I tried downloading Lion from the new iMac but it's not available...
Any ideas?

To get to the App Store, you need to upgrade the Tiger machine to Snow Leopard.

I have CS4 Photoshop on my iMac with Mavericks. I am going to upgrade to Yosemite, and don't think it is compatible with CS4. Do I get the full Photoshop CC version for $9.99 a month, or do I need to buy any additional things?

Thanks, I was thinking so. I installed my CS4 from a CD in 2008, and it looks like Adobe has taken another approach to selling their products. I'll be downloading CC Photoshop a little later today.

I'm looking into the possibility of using Photoshop CS2 on Imac with Mavericks OS. Is this even possible, and if not, what would I need to do?

Is it possible to download and use Photoshop CS2 on Imac with Mavericks OS?

This is not a photography question. It is an application specific question, Please post in the Photoshop forum.

I am a teacher of mathematics and i have a windows pc, but i want to do the next step. I want to buy an iMac. I want to learn how to write mathematical equations and how to do geometrical schema in my documents with iMac. Help me please!!! Thank you very

Bonjour VAGRAI
1) To write math expressions in a text :
     — Microsoft Office 2011 etc. for Mac use its included Equation Editor.
     — OpenOffice.org (OOo) and NeoOffice : download free Dmath 3.3.
     — iWork (Pages, Numbers, Keynote), download free MathType 6.7, fully functional for 30 days, then becomes « Lite » for life as good as the Microsoft equation editor ; it’s better than using Grapher’s equation editor (Applications > Utilities) because MathType can be called from Pages and allows editing equations by clicking the math expressions your text (details on MathType website) .
     — Graph.app 2.3 in Mountain Lion is built to draw curves and surfaces from equations, so it uses an equation editor less powerful than mathType, but it’s easier typing expressions. You may get 2D 3D geometrical drawings from clever equations. Suggest a glance at   http://y.barois.free.fr/grapher/ to know all about Grapher (83 pages Instructions for Use - Grapher) and some examples
2) Geometrical schema :
     — GeoGebra is very popular and used by math teachers.
     — Google SketchUp 8 was not built for mathematics but for architecture, but it’s very easy using it to draw 2D 3D surfaces and solid figures.
     — ShapeOnYou.app allows simples geometrical figures http://pierre.chachatelier.fr/programmation/shapeonyou_en.php
3) Some useful websites for screen shots of geometrical schema :
     http://www.mathcurve.com/
     http://perso.orange.fr/roger.assouly/
Drawings files PDF, TIFF, JPG … can be inserted in an iWork window (Pages).
I hate LaTex : not necessary to write math books !
Au revoir VAGRAI,
YB24
Attachment : lines and curves were made with Google SketchUp 8, screen copied (Command-Shift-4), inserted on a Pages sheet to add letters figures rectangles title.
SketchUp allows drawing precisely an arc of circle 325 mm radius 22,5° angle for instance.

I've updated my Macbook Pro and my iMac with Maverick, updating the various apps. On my Macbook, everything functions perfectly. On my iMac, I get the Your System has Run out of Application Memory, and it's based our Mail, the only app not updated. Ideas?

Maverick and Your System message
I've updated my Macbook Pro and my iMac with Maverick, updating the various apps (Pages, Aperture, iPhoto, Numbers & iMovie, too) in the process.
On my Macbook, everything functions perfectly. On my iMac, I get the Your System has Run out of Application Memory message. But it's not Calendar, it's Mail that not only won't open, but when it does now, it takes the entire system out with it.
I open Safari, and it works. I open Firefox, and it works and Safari still works. I open Calendar and it works, Safari and Firefox continue to work. I open Reminders, and everything still works.
I open Aperture, and it opens Finder instead, showing the 3.5 update that was installed two days ago (and Aperture has functioned), but doesn't seem to update the app; after about 20 seconds the update disappears and I can now open Aperture and it shows I'm now opening the updated Aperture, which it didn't show before.
I click on Mail, and the cursor spins for ten minutes. The mail window finally opens, but the cursor spins and does not connect to upload new mail, and I finally Force Quit Mail. Since the Maverick update, even though Mail was not updated (and maybe because Mail was not updated), I have been able to receive emails twice, and then the program crashed.
Besides the Aperture app, Pages didn't fully update on the iMac, and I had to remove the old Pages icon from the dock after the new program loaded up from Applications.
Any ideas?

I have a Bootcamp partition on my Imac with Mavericks which I can't delete because the Partition Layout is greyed out and is stuck on 'Current'. What can I do?

I have a Bootcamp partition on my Imac with Mavericks which I can't delete because the Partition Layout in Disk Utility is greyed out and is stuck on 'Current'. What can I do? I was trying to install Windows 8.1 but apparently, this is not yet possible.
I was originally able to restore to my original Mac OSX partition using Boot Camp Assistant but then after entering Disk Utility and re-RAIDing the default RAID 1 to RAID 0 in the BootCamp partition (I suspect this is the cause of the problem but why was it defaulted to RAID 1 in the first place?!!!!), forever afterwards, I couldn't restore the single OSX partition.
Whenever I used BootCamp Assistant my choice to 'Install or remove Windows 7 or later version' was greyed out. Finally I went to Disk Utility to repartition but the Macintosh HD and BootCamp disk partition functions were also greyed out (even if I started up from Recovery mode holding down option, command and 'R' and choosing Disk Utility). BootCamp Assistant gives the error message 'The startup disk cannot be partitioned or restored to a single partition' with additional small script 'The startup disk must be formatted as a single Mac OS Extended (Journaled) volume or already partitioned by Boot Camp Assistant for installing Windows', and DU gives the error message 'The full size of the Fusion drive is not available for repartitioning'.
What can I do to fix this problem? How can I make the Partition Layout button active in DU so I can change the partition to all OSX? I'm prepared to wipe off all my data etc to repartition and have backed up all to disk using Time Machine.

My problem is fixed now, thank you. It was caused by my changing the Boot Camp partition's 'RAID1' to 'RAID0'. If I hadn't done that, Boot Camp would still have been able to 'restore' back to the one partition. It was fixed with the help of Applecare by using a terminal and typing a command to erase the IP of the Macintosh disk (not the volume) as well as the IP of the Bootcamp partition (if I remember correctly), but then I had to restore the OS and all my applications and data etc which I had previously backed up using Time Machine. I haven't taken note of the exact command terminology used. It would be wise to speak to Applecare about this if possible.
Two words of warning, 1. According to the cause of this problem, it might be wise, after reinstalling the ops system to reinstall all extra applications one by one, manually, in case a similar problem arises again. Then manually copy back all data. Or the Mac user could use the Time Machine backup and then uninstall all the added apps then re-install them one by one manually. 2. Beware as after all this the user might not have the 'Recovery partition'. There is a small recovery partition (a few 100 Mb is size) which comes with all later Macs. After all this is done this tiny partition might not be there anymore and the user might have to re-install Mavericks again to get it back, or just install the upcoming update of Mavericks due in a month or so.

I downloaded Downlite by mistake on my iMac 27 with mavericks. how do I remove it? and how dangerous is for the computer?
