How do I speed up my computer? Version OS X 10.8.5 Processor 2.66 GHZ Memory 2GB 20 inch 2009

The 2 places I’ve seen recommended most to buy reliable RAM are below. I have purchased RAM several times from Other World Computing and have always been very satisfied with the product and service. They also have on-line instructions on how to replace the RAM. OWC has also tested RAM above what Apple states is the minimum. I now have 6GB installed on a machine supposedly limited to 4 GB.

How did I speed up my computer?

Mac OS 10.5.8 desktop I am having difficulty with slow repsonses eespecially on Imovie. I have lots of pictures and videos and have them all in Iphoto, how do I condense these and stillhave use of them for imovie. I am thinking that is why my computer is slow. Please help!!

Hi Rebecca,
Very Important, how much Free Space is on your Hard Drive first of all? Click on the Macintosh HD on the Desktop, then do a Get Info on it.
How many items do you have on the Desktop? The more you have, the slower it'll be.
So we know more about it...
At the Apple Icon at top left>About this Mac, then click on More Info, then click on Hardware> and report this upto but not including the Serial#...

The spinning colorwheel come up frequently on my MacbookPro, how do i speed up my computer?

I have a MacBookPro that i use for DJing. I frequently get the spinning colorwheel. How do i stop that from coming up so often. I've increased my RAM from 4GB to 8GB. My original 320GB HD was replaced by a 500GB HD at the Apple Store when the original one failed. At this time I cannot upgade to OS X Yosemite, until my DJ software is certified to run on it. I'm running OS X 10.9.5 right now.
I saw in other posts a link to EtreCheck to get info from my Mac. I've pasted it below.

How can i speed up my computer

I was wondering if I need to do anything in particular to clean up/speed up my IMac computer. I originally purchased it in early 2010 and have not had any problems per se but at times it does appear to run slow and I am having to wait for the spinning color wheel more often now.
Any suggestions would be greatly appreciated.
Thanks

System crashes when attempting to install 10.6. Keeps asking to restart. Computer is a Dual-Core Intel Xeon processor and 2 GB Memory.

I have tried to install 10.6 and when install is complete it says restart. The computer restarts but keeps coming to a gray screen with a small black box that says to restart. The processor is 2 x 2.66 GHz Dual Core Intel Xeon with 2 GB of memory. This should be more than adequate. Any ideas? Has anyone encountered this before? I had to restore 10.5 from Time Machine.

Your sig line says iMac, but TMK no iMacs were ever made with 2x2.66 GHz processors. Is this a Mac Pro you are installing on? Are you using a retail Snow Leopaard DVD?

How do i install Mac OS X version 10.6.8 on my computer from Mac OS X 10.5 Leopard

how do i install Mac OS X version 10.6.8 on my computer from Mac OS X 10.5 Leopard

Upgrade Paths to Snow Leopard, Lion, and/or Mountain Lion
You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
Upgrading to Snow Leopard
You can purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
     Snow Leopard General Requirements
       1. Mac computer with an Intel processor
       2. 1GB of memory
       3. 5GB of available disk space
       4. DVD drive for installation
       5. Some features require a compatible Internet service provider;
           fees may apply.
       6. Some features require Apple’s iCloud services; fees and
           terms apply.
Upgrading to Lion
If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
You can purchase Lion by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
     Lion System Requirements
       1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
           or Xeon processor
       2. 2GB of memory
       3. OS X v10.6.6 or later (v10.6.8 recommended)
       4. 7GB of available space
       5. Some features require an Apple ID; terms apply.
Upgrading to Mountain Lion
To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
     OS X Mountain Lion - System Requirements
       Macs that can be upgraded to OS X Mountain Lion
         1. iMac (Mid 2007 or newer) - Model Identifier 7,1 or later
         2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) - Model Identifier 5,1 or later
         3. MacBook Pro (Mid/Late 2007 or newer) - Model Identifier 3,1 or later
         4. MacBook Air (Late 2008 or newer) - Model Identifier 2,1 or later
         5. Mac mini (Early 2009 or newer) - Model Identifier 3,1 or later
         6. Mac Pro (Early 2008 or newer) - Model Identifier 3,1 or later
         7. Xserve (Early 2009) - Model Identifier 3,1 or later
To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.
Are my applications compatible?
         See App Compatibility Table - RoaringApps.

How to speed up my computer

How to speed up my computer? Basic configuration is as below.
Intel Pentium Dual Core 2.5 GHz Processor
Ram: 2GB
HD: 350 GB
Mother Board: Giga Byte
OS: windows XP
I am using Office2007 in my PC. I have enable firewall. Can I disable it? If so, then how to protect my pc from virus attack?

There are a lot of different things you can do to speed up your PC. First off, try to upgrade your ram, You can Google your motherboard model to see how much and what kind it can hold. Or go to www.crucial.com and run the analyzer that scans your system and tells you what kind and how much ram your PC can handle. You can get ram dirt cheap these days especially if you order it online.
Next you should uninstall any unwanted or unused programs, there is a very good uninstaller called Revo uninstaller, it is free. It removes programs and then scans for registry and other left over files from the PC. Or you can just go to control panel---add or remove programs and do it from there. And while your there you can go to add or remove windows components and disable anything that you don't use.
Click start click run the type "msconfig" (without the "") under the startup tab uncheck anything that is not necessary to run at startup. This will make your PC boot faster.
If you go to www.blackviper.com/WinXP/servicecfg.htm they have a complete guide to disabling unneeded services on a 32 bit windows XP PC. There are a lot of services that you will never need or do not use. Make sure you click on each service you are thinking about disabling and read what it is first. You don't want to disable anything you need on accident.
I use CCleaner to clean, defrag and compress the registry. There are other free and paid programs out there to tidy up your registry which gets a lot of errors and unnecessary entries in it every time you use your PC.
When you store a files on your PC they get fragmented and this slows your system down. Again there are a lot of free programs to defrag your hard drive. I use Ultimate Defrag. With this program you can place your most used files(windows files etc) on the outer rows of your hard drive (fastest part) and the least used files or archive files on the inner rings. It gives you many options to defrag as well as just simple defrag.
I would keep the firewall on or get a third party one. I don't know what anti virus you use but there are numerous reviews and guides online as to which ones are the fastest and have the lightest footprint. I use Esset, but there are a few good free ones also. If you think you have a problem with a virus or malware download and run superantispyware pr malwarebytes, and use it alongside of your anti virus.
Go to your local bookstore and look at the PC magazines. A lot of them have good tips to make your PC run faster and some come with free CDs that have a lot of freeware/shareware programs on them.
Hope this helps

I inadvertently deleted and emptied the trash bin on Firefox. I have a MAC OSX-VERSION 10.4.11. How can I re-install the latest version of Firefox that is COMPUTER FRIENDLY for the MAC OSX Version 10.4.11? I appreciate any help.

I inadvertently deleted Firefox and emptied the trash bin. I believe it was version 3.5. I have a MAC OSX 10.4.11. After several futile attemps how can I re-install the latest version of Firefox compatible to my MAC system? Thanks!

As of Firefox 4.0 and newer the Firefox builds from Mozilla requires both Mac OSX 10.'''5'''+ and a Intel.
Either you can use 3.6.19 from http://www.mozilla.com/en-US/firefox/all-older.html
Though for you 3.6.18 will be safe also as 3.6.19 was to workaround a font crashing issue on 10.7 Lion that was not fixed in time on Lion before release. http://releases.mozilla.org/pub/mozilla.org/firefox/releases/3.6.18/mac/ and pick your language and download the Firefox 3.6.18.dmg

Firefox 5.0 doesn't work on my computer (xp) how can i download the 4.0 version

I have a window XP, since i updated firefox to 5.0, it doesnt work. i uninstalled it to install the 4.0 version. But whenever i want to download it only offers the 5,0.
How can i download the 4.0 version???

Firefox 4 versions and later do not run on a PowerPC Mac. Firefox 4 and later require at least OS X 10.5 and an Intel Mac.
http://www.mozilla.org/en-US/firefox/8.0/system-requirements/
Firefox 3.6.24 (Mac OS X 10.4 and later) can be found here:

How can I speed up my MacBook Air?

Hi folks,
My MacBook Air has gotten painfully slow over time but I can't afford to buy a new one right now. It freezes for a few seconds at a time, all the time, especially when I am using Chrome.* Any ideas for how to speed it up?
Specs are:
Model: 13-inch, Late 2010
Processor: 1.86 GHz Intel Core 2 Duo
Memory: 2 GB 1067 MHz DDR3
Software: Mac OS X Lion 10.7.5 (11G63b)
Graphics: Graphics NVIDIA GeForce 320M 256 MB
Storage: The Mac partition is 75 GB, of which 44 GB are free (there is also a 45GB Bootcamp partition).
I was running out of disk space, which I thought was causing the problem by cramping the space available for the swapfiles, which in turn was requiring extra disk activity (you can see that discussion here). There is a clear correlation b/w disk activity and CPU Usage (the two screenshots were taken back to back last night; the dock icon for Activity Monitor is showing CPU history):
However repartitioning to add another 35GB of free space to the Mac partition didn't do anything. In fact, the swapfile sizes are exactly the same as they were two weeks ago when I posted the other question (this is from just now):
I was thinking about buying an aftermarket SSD to increase the storage size, but if increasing the partition size didn't help it doesn't seem that will either.
Thanks much!
* The big memory and CPU hog is Chrome, and in particular gmail, but my workflow is pretty dependent on working in the cloud. I use Firefox and Safari from time to time, but my experience with those is that they run all tabs in a signel process, so to free up memory you have to close the entire browser, and if one tab crashes the whole browser does, whereas with chrome you can kill individual tabs if they freeze and/or to free up their memory.

You need more RAM if that's possible in your model. I think you can go up to 4 GBs. You will use more swap space as memory availability declines.
About OS X Memory Management and Usage
Using Activity Monitor to read System Memory & determine how much RAM is used
Memory Management in Mac OS X
Performance Guidelines- Memory Management in Mac OS X
A detailed look at memory usage in OS X
Memory Usage Performance Guidelines- About the Virtual Memory System
Understanding top output in the Terminal
The amount of available RAM for applications is the sum of Free RAM and Inactive RAM. This will change as applications are opened and closed or change from active to inactive status. The Swap figure represents an estimate of the total amount of swap space required for VM if used, but does not necessarily indicate the actual size of the existing swap file. If you are really in need of more RAM that would be indicated by how frequently the system uses VM. If you open the Terminal and run the top command at the prompt you will find information reported on Pageins () and Pageouts (). Pageouts () is the important figure. If the value in the parentheses is 0 (zero) then OS X is not making instantaneous use of VM which means you have adequate physical RAM for the system with the applications you have loaded. If the figure in parentheses is running positive and your hard drive is constantly being used (thrashing) then you need more physical RAM.
Adding RAM only makes it possible to run more programs concurrently. It doesn't speed up the computer nor make games run faster. What it can do is prevent the system from having to use disk-based VM when it runs out of RAM because you are trying to run too many applications concurrently or using applications that are extremely RAM dependent. It will improve the performance of applications that run mostly in RAM or when loading programs.
Kappy's Personal Suggestions About OS X Maintenance
For disk repairs use Disk Utility. For situations DU 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. Drive Genius provides additional tools not found in Disk Warrior for defragmentation of older drives, disk repair, disk scans, formatting, partitioning, disk copy, and benchmarking.
Four outstanding sources of information on Mac maintenance are:
1. OS X Maintenance - MacAttorney.
2. Mac maintenance Quick Assist
3. Maintaining Mac OS X
4. Mac Maintenance Guide
Periodic 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.) See Mac OS X- About background maintenance tasks. If you are running Leopard or later these tasks are run automatically, so there is no need to use any third-party software to force running these tasks.
If you are using a pre-Leopard version of OS X, 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 after Tiger. (These utilities have limited or no functionality with Snow Leopard, Lion, or Mountain Lion and should not be installed.)
Defragmentation
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 except when trying to install Boot Camp on a fragmented drive. But you don't need to buy third-party software. All you need is a spare external hard drive and Carbon Copy Cloner.
Cheap and Easy Defragmentation
You will have to backup your OS X partition to an external drive, boot from the external drive, use Disk Utility to repartition and reformat your hard drive back to a single volume, then restore your backup to the internal hard drive. You will use Carbon Copy Cloner to create the backup and to restore it.
1. Get an empty external hard drive and clone your internal drive to the
       external one.
2. Boot from the external hard drive.
3. Erase the internal hard drive.
4. Restore the external clone to the internal hard drive.
Clone the internal drive to the external drive
1. Open Carbon Copy Cloner.
2. Select the Source volume from the left side dropdown menu.
3. Select the Destination volume from the left side dropdown menu.
4. Be sure the Block Copy button is not depressed or is ghosted.
5. Click on the Clone button.
Destination means the external backup drive. Source means the internal startup drive.
Restart the computer and after the chime press and hold down the OPTION key until the boot manager appears. Select the icon for the external drive and click on the upward pointing arrow button.
After startup do the following:
Erase internal hard drive
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your internal hard drive (this is the entry with the
       mfgr.'s ID and size) from the left side list. Note the SMART status of the
       drive in DU's status area. If it does not say "Verified" then the drive is
       failing or has failed and will need replacing. SMART info will not be
       reported on external drives. Otherwise, click on the Partition tab in the
       DU main window.
3. Under the Volume Scheme heading set the number of partitions from the
       drop down menu to one. Set the format type to Mac OS Extended
       (Journaled.) Click on the Options button, set the partition scheme to
       GUID then click on the OK button. Click on the Partition button and wait
       until the process has completed.
Restore the clone to the internal hard drive
1. Open Carbon Copy Cloner.
2. Select the Source volume from the left side dropdown menu.
3. Select the Destination volume from the left side dropdown menu.
4. Be sure the Block Copy button is not selected or is ghosted.
5. Click on the Clone button.
Destination means the internal hard drive. Source means the external startup drive.
Note that the Source and Destination drives are swapped for this last procedure.
Malware Protection
As for malware protection there are few if any such animals affecting OS X. Starting with Lion Apple has included built-in malware protection that is automatically updated as necessary.
Helpful Links Regarding Malware Protection:
1. Mac Malware Guide.
2. Detecting and avoiding malware and spyware
3. Macintosh Virus Guide
For general anti-virus protection I recommend only using ClamXav, but it is not necessary if you are keeping your computer's operating system software up to date. You should avoid any other third-party software advertised as providing anti-malware/virus protection. They are not required and could cause the performance of your computer to drop.
Cache Clearing
I recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc. Corrupted cache files can cause slowness, kernel panics, and other issues. Although this is not a frequent nor a recurring problem, when it does happen there are tools such as those above to fix the problem.
For emergency cleaning 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 works with Snow Leopard or earlier.)
Installing System Updates or Upgrades
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand. I also recommend booting into safe mode before doing system software updates.
Backup and Restore
Having a backup and restore strategy is one of the most important things you can do to maintain your computer. Get an external Firewire 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. Deja Vu
3. SuperDuper!
4. Synk Pro
5. Tri-Backup
Visit The XLab FAQs and read the FAQs on maintenance and backup and restore.
Always have a current backup before performing any system updates or upgrades.
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 or 20 GBs, whichever is greater, as free space. Avoid installing utilities that rely on Haxies, SIMBL, or that alter the OS appearance, add features you will rarely if ever need, etc. The more extras you install the greater the probability of having problems. If you install software be sure you know how to uninstall it. Avoid installing multiple new software at the same time. Install one at a time and use it for a while to be sure it's compatible.

How can I speed up the extract() function queries on XML

Hi,
Please I need some light on xml and indexes.
This is my case:
I use Oracle 9i R2.
I have a table with some rows containing some few xml documents (each row contains a big xml document).
Given a value for an attribute of a tag, I want to extract the entire section within the tags.
Example:
<MYTAG number="1">
.....big stuff here
</MYTAG>
<MYTAG number="2">
.....big stuff here
</MYTAG>
<MYTAG number="x">
.....big stuff here
</MYTAG>
So for number=2 I would like to extract from the document the xmltype
<MYTAG number="2">
.....big stuff here
</MYTAG>
I created an index and have followed all the steps from the XML Database Developers Kit manual. Then I would use extrac() as the document says.
Now some doubts arised:
Are these text/xml indexes only useful for getting the rowid of my document?
I mean, if I select 'x' from the table looking for some value, then the index is used. But when I use extract in the select to get the section I look for, the query gets really low, specially when xml documents are big. I think when I have only row with one document, getting the rowid is not the problem, but the extraction from the document is.
Is the extraction process faster because of the index?
For what I see, the index only helps me to find the rowid, but then Oracle has to deal with the very big document inside the row. At that point Its oracle against a big text processing and index has nothing to do.
How can I speed up the extraction of the section?
If there any other index or tool for help extraction to be faster?
I would appreciate to know what can I do. I need help on this.
Thanks in advance!

Well,
- What indexes, if any, already exist?
- What do the functions rl and nice do?
- What are the current query plans?
- How restrictive are the various predicates?
- What version of Oracle?
