My downloads are making my computer run too slow - can I delete?

Help! Call me stupid, or computer illiterate or whatever. But, I don't know what to do. All of my music is stored in ITunes. My computer is running really slow and I am running out of space. Can I delete my music without losing it? Will it still be held in my Itunes account? Thanks for the help

You need some kind of backup. If you just delete it from your PC and keep it on your iPod, when you need to restore your iPod (and you will, at some point) your music will be lost.
You'll either have to reburn CDs you own, or repurchase music from the iTunes store.
You only get one download from iTunes:

Since i added osx mountain lion, my computer runs really slow, especially internet

Can I go back to what I had before (I think snow leopard?)? This new software is making my computer run too slow. I sometimes have to wait a full minute just to get online. Sometimes, I have to turn the whole computer off and back on again to get online. Can't stand it!

To revert, see Revert your Mac to Snow Leopard

For general advice see Troubleshooting issues with iTunes for Windows updates.
The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down the page in case one of them applies.
The further information area has direct links to the current and recent builds in case you have problems downloading, need to revert to an older version or want to try the iTunes for Windows (64-bit - for older video cards) release as a workaround for installation or performance issues, or compatibility with QuickTime or third party software.
Your library should be unaffected by these steps but there also links to backup and recovery advice should it be needed.

FCP X running too slow

I am experiencing FCP running too slow, finding it hard to edit footage.

You are not the first to see this slow down.. But often by deleting render files can solve this slow down or restart the computer. I know this should not be so, but untill Apple make some fixes there is little to ad. You are actually doing everything right. And I assume you are using better formance not high quality.

I play a lot of games. I noticed my computer running much slower what can I do

I play a lot of games. I noticed my computer running much slower. Is there something I can do to fix probkem

Things You Can Do To Resolve Slow Downs
If your computer seems to be running slower here are some things you can do:
Start with visits to:     OS X Maintenance - MacAttorney;
                                  The X Lab: The X-FAQs;
                                  The Safe Mac » Mac Performance Guide;

Boot into Safe Mode then repair your hard drive and permissions:
Repair the Hard Drive and Permissions Pre-Lion
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. 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 installer.
Repair the Hard Drive - Lion/Mountain Lion/Mavericks
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the Utilites 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 disk icon and click on the arrow button below.
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, then click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
Restart your computer normally and see if this has helped any. Next do some maintenance:
For situations Disk Utility cannot handle the best third-party utility is Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible.
Note: Alsoft ships DW on a bootable DVD that will startup Macs running Snow Leopard or earlier. It cannot start Macs that came with Lion or later pre-installed, however, DW will work on those models.
Suggestions for OS X Maintenance
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger. These utilities have limited or no functionality with Snow Leopard or later and should not be installed.
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive.
Helpful Links Regarding Malware Protection
An excellent link to read is Tom Reed's Mac Malware Guide.
Also, visit The XLab FAQs and read Detecting and avoiding malware and spyware.
See these Apple articles:
          Mac OS X Snow Leopard and malware detection
          OS X Lion- Protect your Mac from malware
          OS X Mountain Lion- Protect your Mac from malware
          About file quarantine in OS X
If you require anti-virus protection I recommend using VirusBarrier Express 1.1.6 or Dr.Web Light both from the App Store. They're both free, and since they're from the App Store, they won't destabilize the system. (Thank you to Thomas Reed for these recommendations.)
Troubleshooting Applications
I recommend downloading a utility such as TinkerTool System, OnyX, Mavericks Cache Cleaner, or Cocktail that you can use for removing old log files and archives, clearing caches, etc. Corrupted cache, log, or temporary files can cause application or OS X crashes as well as kernel panics.
If you have Snow Leopard or Leopard, then for similar repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. Applejack does not work with Lion and later.
Basic Backup
For some people Time Machine will be more than adequate. Time Machine is part of OS X. There are two components:
1. A Time Machine preferences panel as part of System Preferences;
2. A Time Machine application located in the Applications folder. It is
    used to manage backups and to restore backups. Time Machine
    requires a backup drive that is at least twice the capacity of the
    drive being backed up.
Alternatively, get an external drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
1. Carbon Copy Cloner
2. Get Backup
3. Deja Vu
4. SuperDuper!
5. Synk Pro
6. Tri-Backup
Visit The XLab FAQs and read the FAQ on backup and restore. Also read How to Back Up and Restore Your Files. For help with using Time Machine visit Pondini's Time Machine FAQ for help with all things Time Machine.
Referenced software can be found at MacUpdate.
Additional Hints
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
Add more RAM. If your computer has less than 2 GBs of RAM and you are using OS X Leopard or later, then you can do with more RAM. Snow Leopard and Lion work much better with 4 GBs of RAM than their system minimums. The more concurrent applications you tend to use the more RAM you should have.
Always maintain at least 15 GBs or 10% of your hard drive's capacity as free space, whichever is greater. OS X is frequently accessing your hard drive, so providing adequate free space will keep things from slowing down.
Check for applications that may be hogging the CPU:
Pre-Mavericks
Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Mavericks and later
Open Activity Monitor in the Utilities folder. Select All Processes from the View menu. Click on the CPU tab in the toolbar. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Often this problem occurs because of a corrupted cache or preferences file or an attempt to write to a corrupted log file.

Can you see which apps are open and/or running like you can on an android phone by going to settings applications running services?

can you see which apps are open and/or running (like you can on an android phone by going to settings>applications>running services)?

Hi wjosten,
thank you for the help. I should have said I had a iphone 3. A friend has the same phone and she showed me how she can see what web pages are open when she double taps the home button. Mine is set to bring up favourites when I double tap (chosen from settings>general>home button).. BUT my choices are only HOME; SEARCH; PHONE FAVORITES; CAMERA or IPOD. I changed my choice to HOME but that just defeats the purpose as when I am at the home page and double tap nothing happens. Am I making sense?

I upgraded to Yosemite and computer running very slow. It is an older iMac 2009. Thinking of downgrading os or upgrading ram unless there is something else I can try?

could the launch agents failing slow the computer or they just don't work. I mean I am willing to upgrade ram but not if there is good chance it won't change speed much. Also to downgrade is it necessary to format the hard drive?

I have an ipad3(wifi cellular). Now i want to upgrade my iOS5.1 to ios 7. But download speed in our country is too slow(100kbps). It can be disconnected anytime. Is there any problem if net connection get disconnected while upgrading ios? Please ans me.

haha, so now i'm thinking. I'm learning the terminal as fast as i can but there are several lines of codes and commands in there that throws up red flags to me that i don't fully understand. It just looks fishy too me. It would be highly appreciated if someone could just check this out just to tell me that i don't need to worry about it. Or point me in the right direction. I just feel un easy about this. ha.

APO - SNP Alert Macros running too slow

Hi,
We have created alert macros which run for next 27 weeks for 38000 Product-Location Combinations. They are running too slow.
We are deleting alerts externally using program /sapapo/amon_reorg and then running this macro with "ADD" . This macro slows down once it starts filling up alert table with 100,000 records. What are the best practices for writing the macro so that it runs fast ?.
Thanks.

Is it necessary to write all the alerts? What I mean is, do you filter the results when you view them through the Alert Monitor?
If your alert profile has a minimum threshold set for an alert type, then you can read this threshold in the macro and only write alerts that fall below the threshold.
e.g.
Step: Get Threshold Values : ( 1 Iterations :Initial;Initial )
    Action Box: Get Threshold Value
      LAYOUTVARIABLE_SET( 'Alert_Thresh' ;
      ALERT_PROFILE_THRESH( SDP_ALERT_PROFILE' ; '4100' ; 'I' ) )
Where SDP_ALERT_PROFILE is the profile that contain sthe minimum threshold you want to use and 4100 is the alert type. The I is for information, can use either W for Warning or E for Error as well.
Then use the variable Alert_Thresh to check if your value falls below this, only then write the alert.
Regards
Ian

Ever since I installed MAVERICK, nothing now works, Flash Player won't run, printer works but scanner will not and the computer runs so slow. Any help anywhere?

Ever since I installed MAVERICK, nothing now works, Flash Player won't run, printer works but scanner will not and the computer runs so slow. Any help anywhere?

wqn02h, first thing I would do is use Disk utility to repair permissions. Once this is done. Make sure you have the latest versions of the software you use. Also, check the manufacter of your printer/scanner for updated software. If they don't have updated software there are 3rd party alternatives that will work.

@ O.P.,
You cross-posted this to at least two other forum web sites:
http://www.linuxquestions.org/questions/solaris-opensolaris-20/application-running-too-slow-on-sun-sparc-t5440-but-run-normal-on-sun-m3000-4175411155/
http://www.unix.com/solaris/189945-application-running-too-slow-sun-sparc-t5440-but-run-normal-sun-m3000.html
... and didn't think that was important enough to simply mention the fact.
Timestamps suggest that OTN was the last place you posted to.
Poor forum etiquette.
Why would anyone spend the time to try to give help that you have already received elsewhere? That's a waste of their time.
(Yes, you already received the suggestion to use Dtrace in one of those other sites.)

I have 1 Mac computer running Lion. Can I set up 'find my iPhone' and 'find my iPad' if both of these devices use different Apple ID's than the Mac does? As in, can I set up 'find my "device"' for my husband's iPhone and my daughters iPad?

No, but you can log into any of their accounts on your computer at iCloud.com and see their devices.
