Too often people upgrade only to find their problems begin, or persist.
If you need help with a slow Mac running a Mac operating system, please be prepared to answer these questions, or find out how to get the answer to these questions.
Etrecheck, a software written by one of our fellow contributors, is a software that has been useful in isolating many of the issues below:
Look at these troubleshooting steps. Find
1. If MacKeeper was installed, and if it is, remove it with the instructions in this tip:
2. If any other system cache cleaner is installed. If there is, contact the vendor on how to remove it.
3. If the possibility your hard drive is over 85% full exists.
4. If Spotlight hasn't finished indexing. (does not apply to 10.3.9 or earlier). Clicking on the icon in the upper right that looks like:
(it may have a different color), will reveal if Spotlight is indexing, or is ready to search. Going to Apple menu -> System Preferences -> Spotlight -> Privacy will show if a specific folder or drive is ignored by your last Spotlight index.
5. If you are attempting to multitask with a Time Machine backup going on. (does not apply to 10.4.11 or earlier)
6. If permissions are damaged. Often a problem when using pre-2006 Classic environment on PowerPC Macs. See #10 how to identify Macs.
7. If third party software or drivers hasn't been tested with your installed operating system.
8. If You migrated data from a different Mac CPU type. I.e. from PowerPC to Intel, or Intel to PowerPC. See 10 on how to identify Macs.
9. If energy saver isn't giving some peripheral problems, because the peripheral doesn't understand low power mode.
10. If the possibility exists that there is marginal hardware on
Intel Macs or PowerPC Macs
Use: https://discussions.apple.com/docs/DOC-6413 to determine if you have PowerPC or Intel.
11. If you have had 4 language screens forcing you to restart your Mac, that's significant, and indicates what is known as a kernel panic.
Usually an issue relating to the hardware, though sometimes a directory may be damaged, or sometimes a bad or incompatible driver is installed.
Running the hardware test for Intel Macs or PowerPC Macs
will indicate if some RAM is bad, but not all RAM. Any errors found with it are significant.

12. If you don't have a current system, find out if a website you are visiting needs a newer plugin for Java, Flash, etc..(10.7.2 or earlier do not run a current Java. 10.6.7 or earlier do not run a current Flash. But updating to those is only necessary for a few websites. Check before updating to ensure you don't make yourself incompatible in other ways). Before updating to 10.7 or later, be sure to read this tip about compatibility first: https://discussions.apple.com/docs/DOC-6271
13. If your data is backed up from before or after the upgrade, and we can isolate other issues. Without a backup, we can't say if the solution might be worse than the problem.

14. Slowdown to internet applications may be due to third party router firmware not being up to date, too many machines using the router, an insecure router not using WPA2 connectivity (802.11b original Apple Airport can't use it, and it is better to get a WiFi ethernet bridge with at least 802.11g), proxy servers, and bad DNS issues which http://www.opendns.org/ can resolve. Additional WiFi related issues are documented on this tip:
15. A bad iTunes install, or one that isn't properly updated for the system may cause slow down. If you are trying to isolate that as a possibility, note the path to the iTunes Helper which is loaded in your System Preferences -> Accounts (Users and Groups in some versions of Mac OS X), Login Items (startup items in other versions of Mac OS X)
/Applications/iTunes.app/Contents/Resources
You can use the Finder's Go to Folder command in the Go menu to reload that program after removing it from your Login Items and troubleshooting the situation.
16. Peer2peer sharing software, torrent software, both make your machine into a software server. This can slowdown your overall internet. Do not get software from such sources, as most are illegal. If you have trouble finding software for your operating system, visit http://www.roaringapps.com/ if using Mac OS X 10.7 or later, or ask on this board where to find software that is legal that does what you need.
17. If your Mac is backed up, then's the time to see if a directory repair is necessary:
18. Often times, you will see the system slowdown and get a spinning color circle indicating it is busy. After a certain amount of time, if you can risk losing the data that has not been saved on the application, force quitting the application with command-option-escape key sequence is a possibility.
If command-option-escape does not work, it may indicate one of the aforementioned issues is happening. Command and Option keys may look like some variation of:
On non-Apple keyboards the Windows key usually takes the place of the Command key, and the Alt key usually the Option key. Though Microsoft has made a patch for its keyboards that forces the two keys to switch their assigned Apple keystroke, since they are in reverse orientation of the Apple keyboard. The Escape key is typically just labelled ESC.
19. You may not experience any of the above issues with games or high end graphics applications. The graphics processor unit (GPU) recommended by the developer should be the one you have installed on your computer. Any others, and speed may be an issue with those programs. It is not to be confused with RAM or your CPU.
20. Migrating data from PowerPC Macs. See first #10 to see if you had a PowerPC Mac you were migrating from. If you did, you may have brought over some drivers the Intel Mac does not understand in the Migration or Setup Assistant. If there is a chance this may have happened, you should see this tip on migration which avoids the issue:
21. Notifications can slow Mac OS X 10.9 down. Go to Apple menu -> System Preferences -> Notifications to disable those notifications you don't need.
22. iCloud syncing (in 10.7.2 and later) can slow things down. Manage iCloud through the System Preferences to ensure syncing only happens when you need it. iSync in Mac OS X 10.6 and earlier can also slow things down when you don't need it.
Thanks to Apple software called Boot Camp, you can run both Windows (XP or Vista) and OS X on one Mac machine. Here’s how to install Boot Camp, which came with Leopard, so you can use both Windows and OS X, interchangeably.
What Is My Mac Address
1Run Boot Camp Assistant (in the Utilities folder under Applications) to make sure that you have the latest firmware on your computer.
You can find any updates at the Apple Web site. Follow any on-screen instructions if you’re updating the firmware. If you’re using a portable computer, make sure to connect the power adapter.

2Create a partition for Windows XP or Vista.
This partition must be at least 5GB and can be as large as the total free disc space on hand minus 5GB. If you don’t plan on doing much in Windows, keep the XP or Vista partition small. If you plan on running graphics-heavy games and a lot of Windows programs, you might devote a larger amount to Windows. Drag the divider to set the partitions for both OS X and Windows. Or click Divide Equally to make equal partitions. Still another option: Click 32GB to devote that much to Windows.
3Insert the Windows CD. Click Start Installation.
If you exited Boot Camp Assistant before installing Windows, open it again, choose Start the Windows Installer, and click Continue.
4When asked to choose the Windows partition, select C: if you’re running Windows XP or select Disk 0 Partition 3 BOOTCAMP if you are running Vista.
This is important. Failure to do so could wipe out your entire Mac OS X startup disk.
5Format the partition.
For Windows XP, format the partition in either the NTFS file system or FAT. FAT provides better compatibility between the two operating systems but is available only if the partition you created for Windows is 32GB or smaller; NTFS is more reliable and secure, but you won’t be able to save files to Windows from Mac OS X. For Vista, format the partition using NTFS. Click Drive Options (Advanced), click Format, and then click OK. Click Next.
6After Windows is installed, eject the Windows disc.
You can do so by going to My Computer, selecting the optical drive (D:), and clicking Eject This Disk in the Systems Task list.
7Insert the Leopard installation disc and follow the on-screen instructions.
You’re loading Boot Camp drivers so that Windows recognizes AirPort, Bluetooth, the iSight camera, the Eject key on the Mac keyboard, networking, audio, graphics, and so on. A Boot Camp control panel for Windows and an Apple Boot Camp system tray item will be added.
8When you see the message that the software “has not passed Windows Logo testing,” click Continue Anyway.
Don’t cancel any driver installers. The computer will restart.
9Follow any Found New Hardware instructions.
What Software Is My Mac Running
As with any new Windows computer, Microsoft requires that you activate your XP or Vista software within 30 days.
