Why is my computer now slower than when I had leopard

I have 10.6.1 and macbook pro 2.4 GHz 500 GB 7200rpm hard drive and now my computer is slower, sluggish with applications, WORD 2008, Endnote X2, Powerpoint, PRIMSM 5.0b, etc,etc. I installed twice now. It was super fast when I had 10.5.8.
SL is NOT faster, it is not smoother. Is there a way to get refunded for this purchase? I also would like to replace SL with Leopard 10.5. Does Apple offer an exchange?
Please help

If you want to go back to Leopard, and assuming your don’t have a clone, a complete TM backup, etc., then you will need to do an erase and install. I would first try the Leopard (i.e., 10.5) DVD. But, you may have to use the Snow Leopard (i.e., 10.6) DVD for the erase part. Let's assume the first for now. Startup from the DVD by holding down c when starting up. Next, when able, choose your language and stop. Then, using the menus at the top, select Disk Utility and erase you drive. Next, quit Disk Utility and continue the install. After the install is complete, insert your Leopard applications disk and install the programs you want. Now, you are done except for restoring you data, apps, and settings using whatever media are available to you.
In the other case, you will have to exit the installer after exiting Disk Utility. Next, you would startup with your Leopard DVD again by holding c down during startup. Now, after selecting your language again, just click install. After the installer is finished, install your applications as above.

Why is my computer now slower, with Firefox 4, then it was with previous version? It stops and crashes constantly. How can I go back to the previous version?

When I am on Facebook or playing a game, it will freeze and I have to hit control alt delete, to get any response. Within a couple more seconds the same problem occurs. I did not have this problem with the previous version.

I tried so hard with FF4 but no deal. It was considerably MUCH slower than 3.6. Every page just had a 2~3 second wait before it loaded up. This was tested on a brand new Windows 7 64-bit install machine too.
Flash ran much more cpu intensive as well. I played many flash based games in 3.6 and my cpu usage was never always as it was with FF4 in the 90%-100% range.
I had to get rid of it due to the slowness and the lack of older plugin support: ANYCOLOR which I must run and cannot stand the light colored menu pop ups. Also the buttons in FF4 are worse than 3.6. You can't see them when you have a persona applied.
Staying with 3.6 until 4 speeds up or will give 4.1 a try.

Computer slower than when new

hello, i been noticing my mac acts slower than when new. im getting the little spinning color wheel alot now when i hardly ever saw it before. i ran my disk permissions and it seems ok. is there anything else i can do to make it fresh again? thanx 4 help

yes i ran them then and when it seemed slow. i havent added fonts that i know of, but i did add a canon mpc600 printer and it had software that may have included fonts im guessing. i ran permissions after that installation. inet seems like normal speed, im on ethernet cause my airport is the bugged type that 24"s have. works fine awhile then no longer connects for whatever reason. i gave up on wireless after weeks of problems. i ran onyx and i noticed immediatly my external drive opened without the spinning color wheel so i think its fixed now. thank you for your reply.

Why the system is very slow than before

I have two computers, One is desktop, another is laptop,but I met the problems about the performance for the two
computers, from last Monday, two computers speed are very slow, after I checked the task manager, I found the service(ntoskrnl.exe) used the 60-70% CPU resource, but why the ntoskrnl.exe cause this? I also download the tools and analysised it, but it seems
that no useful information,how to find the root cause?
summary all the information as below
1.Suddenly this problems happened
2. I closed the AVP (Kaspersky antivirus software), but it seems no improved for the performance
3. I have closed the Windows search service, but no change for this
4\I use the maxthon and Firefox browse

My four year old iMac is running much slower than when it was new. Any suggestions on cleaning out the cob webs?

My four year old iMac is running much slower than when it was new. Does anyone have any suggestions on what I can do to "clean it up" and get it running like it used to?

What year, screen size, CPU speed and amount of RAM installed?
To find out info about your system,
Click on the Apple symbol in the upper left of the OS X main menu bar. A drop down menu appears.
Click About this Mac. A smaller popup window appears. This gives you basic info like what version of OS X your iMac is running, the speed of your iMac's CPU and how much RAM is installed.
Click on the button that says More Info. A larger window appears giving you a complete overview of your iMac's hardware specs.
Highlight all of this info and copy/paste all of this into another reply to this post, editing out your iMac's serial number before actually posting the reply.
This will tell us everything about your iMac so we may begin to help with your iMac issues.
How full is your Mac's hard drive?
Locate your iMac's hard drive icon on the OS X desktop. Click the icon once, then use the keyboard key combination Command-I. This will give you additonal info about your iMac's internal hard drive.
Post this info in your reply here, also.
Here are some general tips to keep your Mac's hard drive trim and slim as possible
You should never, EVER let a conputer hard drive get completely full, EVER!
With Macs and OS X, you shouldn't let the hard drive get below 15 GBs or less of free data space.
If it does, it's time for some hard drive housecleaning.
Follow some of my tips for cleaning out, deleting and archiving data from your Mac's internal hard drive.
Have you emptied your Mac's Trash icon in the Dock?
If you use iPhoto, iPhoto has its own trash that needs to be emptied, also.
If you store images in other locations other than iPhoto, then you will have to weed through these to determine what to archive and what to delete.
If you use Apple Mail app, Apple Mail also has its own trash area that needs to be emptied, too!
Delete any old or no longer needed emails and/or archive to disc, flash drives or external hard drive, older emails you want to save.
Look through your other Mailboxes and other Mail categories to see If there is other mail you can archive and/or delete.
STAY AWAY FROM DELETING ANY FILES FROM OS X SYSTEM FOLDER!
Look through your Documents folder and delete any type of old useless type files like "Read Me" type files.
Again, archive to disc, flash drives, ext. hard drives or delete any old documents you no longer use or immediately need.
Look in your Applications folder, if you have applications you haven't used in a long time, if the app doesn't have a dedicated uninstaller, then you can simply drag it into the OS X Trash icon. IF the application has an uninstaller app, then use it to completely delete the app from your Mac.
To find other large files, download an app called Omni Disk Sweeper.
Download an app called OnyX for your version of OS X.
When you install and launch it, let it do its initial automatic tests, then go to the cleaning and maintenance tabs and run the maintenance tabs that let OnyX clean out all web browser cache files, web browser histories, system cache files, delete old error log files.
Typically, iTunes and iPhoto libraries are the biggest users of HD space.
move these files/data off of your internal drive to the external hard drive and deleted off of the internal hard drive.
If you have any other large folders of personal data or projects, these should be archived or moved, also, to the optical discs, flash drives or external hard drive and then either archived to disc and/or deleted off your internal hard drive.
Good Luck!

Why is InDesign CC significantly SLOWER than CS6?

InDesign CC is noticeably SLOWER in almost every aspect and functionality than is the latest version of InDesign CS6 on my computer (OSX 10.9.4, 2.66 GHz Intel Core i5, 8 GB 1067 MHz DDR3, 27 inch iMac). I have stopped using Indesign CC and now only use CS6 to create and adjust documents.
Can any staff or special users in this forum detail ADOBE's understanding or response to complaints of this nature?
This situation does not bode well for me, given the coerced direction Adobe is taking users of its creative suite (towards cloud based subscription systems).

I rebuilt all my preferences and that led to some kind of discovery. Starting InDesign CC everthing works ok (though the drawing tools are slightly slower than in CS6, creating a new page for example is much faster). All the following things mainly have an impact on drawing tools (pen tool, rectangle tool etc. placing multiple images is also affected but maybe because an image frame has to be drawn). After activating the application frame things start to slow down a bit. If I open the collapsed panels on right side things get slowed down again and the biggest hit on performance is evident when the information panel is open.
I wanted to record a screen-capture again but this is so slow that it does not represent the bug accurately. And I guess this has something to do with the user interface because all is linked to interface actions (application frame, opening/collapsing panels, showing the information panel)
Once again my system specs (when experiencing the issues half of my RAM was still free with Safari, Mail and InDesign CS6 and CC open for comparison):
InDesign CC (German)
Mac OS 10.8.4
MacBook Pro 17inch
8 GB RAM
2.66 GHz Intel Core i7
500 GB HD (200 GB free)

Why is Time Capsule Internet Slower than Belkin Router?

My Time Capsule is conneted via Ethernet to my Belkin Wireless router and is serving as my wireless backup drive.
I am extending the Time Capsule "network" via an AirPort Express in order to boost the signal over distance.
However I find consistently that when I log into the Time Capsule, my internet access is significantly slower than if I access it over the Belkin wireless router, whether I use the Airport Express or not.
I've also found that logging into the Belkin from my Mac to do my Time Capsule backups seem to run considerably faster and have fewer "stalls" than when going direct to the Time Capsule, which also seems quite strange.
Is there some reason for this? Something in my settings conflicting? One would assume that with the Mac going directly to the Time Capsule which is connected directly via Ethernet, that it would be faster than going through the 3rd party Belkin router, or at least no different.

Let me just get it clear..
Belkin is main router..
TC is bridged and plugged into it by ethernet.
Express is doing extend wireless to the TC over 5ghz.
Now there is a couple of misunderstandings..
The Time Capsule is set for the 5GHz band ONLY to avoid conflict with the numerous 2.4GHz radios in close proximity, including the Belkin, automatic channel selection.
TC is not able to shut off the 2.4ghz.. even if you don't use it.. it will work.
So it is better to set it up and use it on fixed wireless channel out of the way. Indeed if it is some distance from the belkin rather than right next to it.. you can use roaming network setup. Both Belkin and TC use the same ssid ie wireless name.. same security ie WPA2 AES = WPA2 Personal. Same security password.
But different channel.. IMHO it is better to lock the wireless channel. Set TC to 11 and belkin to 1.
Wireless channel on 5ghz is less of an issue but I recommend lower end channels.. ie <40.
Extending wireless on 5ghz is often poor.. the range is actually bad.. and link speed can be worse than using 2.4ghz.. so I would carefully test the speed using wireless on 2.4ghz and then on 5ghz. .If possible only use 5ghz on single hop up close to the TC.
Any wireless that does double hop.. ie TC--Express--computer will go at half the speed of TC--computer, if they link at the same speed. This is caused by double hop wireless being highly inefficient way to extend wireless.
If the TC is faster by ethernet via the Belkin than via the TC I would find that difficult to follow and you will need to give me exact model number of the belkin.
That the belkin 2.4ghz wireless is faster than the TC is no surprise.. apple limit wireless to N lite at 2.4ghz.. whereas the belkin is probably 300mbit. And better signal.
You have heaps of testing to do.

Why is Wireless G router slower than Wireless B?

I have a wireless B router (BEFW11S4 V4) that is dropping my internet connection sometimes on a daily basis. To restore it, I have to unplug the power and plug it back in. It's a pain and interferes with my work, so I purchased a wireless G router (WRT54G2) to replace it. Setting it up was quick and painless, but slowed my internet to a crawl. I know that wireless connections are slower than wired, but a direct connection was about 10 times faster (according to several online speed tests) which I find unacceptable.
I have since removed it and gone back to the older faulty router to restore my internet connect to a speed that at least allows me to do my work. I was not unhappy with my connection speed before. I only replaced the router because it was dropping the connection, but I cannot understand why the new router was so much slower.
Any thoughts, hints, or suggestions before I return the new router to the store?
Thanks!

1) What Internet connection speed are you paying for?
2) What Internet connection speed do you get when you wire your computer directly to your modem?
3) What Internet connection speed do you get when you wire your computer to the WRT54G2?
4) What Internet connection speed do you get through a wireless connection to the WRT54G2?
5) Is your computer's wireless adapter a wireless b? g? n?
There are many causes for poor wireless connections, and many solutions:
First of all, give your network a unique SSID. Do not use "linksys". If you are using "linksys" you may be trying to connect to your neighbor's router. Also set "SSID Broadcast" to "enabled". This will help your computer find and lock on to your router's signal.
Poor wireless connections are often caused by radio interference from other 2.4 GHz devices. This includes wireless phones, wireless baby monitors, microwave ovens, wireless mice and keyboards, wireless speakers, and your neighbor's wireless network. In rare cases, Bluetooth devices can interfere. Even some 5+ GHz phones also use the 2.4 Ghz band. Unplug these devices, and see if that corrects your problem.
In your router, try a different channel. There are 11 channels in the 2.4 GHz band. Usually channel 1, 6, or 11 works best. Check out your neighbors, and see what channel they are using. Because the channels overlap one another, try to stay at least +5 or -5 channels from your strongest neighbors. For example, if you have a strong neighbor on channel 9, try any channel 1 through 4.
Also, try to locate the router about 4 to 6 feet above the floor, in an open area. Do not locate it behind your monitor or near other computer equipment or speakers. If you have external antenna, they should be vertical.
Also, in the computer, go to your wireless software, and go to "Preferred Networks" (sometimes called "Profiles" ). There are probably a few networks listed. Delete any network named "linksys". Also delete any network that you do not recognize, or that you no longer use. Delete your current network (this will remove any old settings.) Reboot computer. Return to "Preferred Networks" and re-enter your current network info (SSID, encryption (if any), and key (if any) ). Then select your current network and make it your default network, and set it to automatic login. You may need to go to "settings" to do this, or you may need to right click on your network and select "Properties" or "settings". Reboot computer. You should connect automatically (it can take up to 2 minutes). If you have trouble connecting, in the computer, temporarily turn off your computer software firewall, and see if that helps.
If the above does not fix your problem, download and install the latest driver for your wireless card.
Some users have reported improved wireless performance by switching from WEP to WPA encryption.
If you continue to have problems, try the following:
For wireless g routers, try setting the "Transmission Rate" to 54 Mbps.
If you still have trouble, download and install the latest firmware for your router. After a firmware upgrade, you must reset the router to factory defaults, then setup the router again from scratch. If you saved a router configuration file, DO NOT use it.
Hope this helps.

Why is Thunderbolt so much slower than USB3?

I'm considering two different drives for Time Machine purposes. Both are LaCie. Either of these:
- Two Porsche 9233 drives, 4 TB each
OR
- A 2Big Thunderbolt drive, 8 TB, which I would configure as RAID 1 (a mirrored 4 TB volume)
My question is this: I've viewed both of these product pages via the Apple Store, and I noticed that LaCie's information for the Thunderbolt drive makes it a lot slower than the USB drives. Meaning: They say that the 2Big Thunderbolt drive maxes out at like 427 MB/s, whereas the Porsche USB drives max out at 5 GB/s. Why is this? Isn't Thunderbolt supposed to be a lot faster than USB (any iteration)?

Not an easy question, short of a whole lot more detail on the construction of those two devices.   You're likely going to need to look at the details of the drives and probably at some actual data.   You're really looking for some real benchmark data that you can compare, in other words.    Particularly which (likely Seagate) drives are used in those (IIRC, Seagate bought LaCie a while back), and what the specs are.
The hard disk drives themselves are a central factor, where the drive transfer rate is a key metric for big transfers (and that can be based on drive RPM as much as anything, faster drives can stream more data, but they tend to need more power and run hotter), and access (seek) time for lots of smaller transfers (faster seeks mean faster access, so good for lots of small files scattered around). Finding the details of the drives can be interesting, though. I've seen lots of cheaper disks that spin very slowly, which means that they can have nice-looking transfer times out of any cache, but then... you... wait... for... the... disk... to... spin.
The device bus interfaces can also vary (wildly) in quality.   I've seen some decent ones, and I've seen some USB adapters that were absolute garbage.   Some devices have decent quantities of cache, too. Others have dinky caches, and end up doing synchronous transfers to hard disks, and that's glacial compared with memory speeds.
One of your example configurations also features RAID 1 mirroring, which means that each write is hitting both disks.   The writes have to pass through a controller that can do RAID 0 mirroring, and that can write the I/O requests to both drives, and that can read the data back from (if it's clever) whichever of the two drives is best positioned in related to the sectors you're after.   If it's dumb, it won't account for the head positions and drive rotation and sector target.   Hopefully the controller is smart enough to correctly deal with a disk failure; I've met a few RAID controllers that weren't as effective when disks had failed and the array was running in a degrated mode. In short, RAID 1 mirroring is a reliability-targeted configuration and not a performance configuration. It'll be slower. Lose a disk in RAID 1 mirroring, and you have a second disk with a second copy.    If the controller works right.
If you want I/O performance without reliability, then configure for RAID 0 striping.   With that configuration, you're reading data from both disks. But lose a disk in a RAID 0 striping configuration and you're dealing with data recovery, at best. If the failure is catastrophic, you've lost half your data.
But nobody's going to make this choice for you, and I'd be skeptical of any specs outside of actual benchmarks, and preferably benchmarks approximating your use. Reliability is another factor, and that's largely down to reputation in the market; how well the vendor supports the devices, should something go wrong. One of the few ways to sort-of compare that beyond the reviews is the relative length of the warranty, and what the warranty covers; vendors generally try to design and build their devices to last at least the length of the warranty.
Yeah. Lots of factors to consider. No good answers, either. Given it's a backup disk, I'd personally tend to favor eliability and warranty and less about brute speed.
Full disclosure: no experience with either of these two devices. I am working with Promise Pegasus Thunderbolt disk arrays configured RAID 6 on various Mac Mini configurations, and those support four parallel HD DTV video streams with no effort. The Pegasus boxes are plenty fast. They're also much more expensive than what you're looking at.
