Upgrade to Snow Leopard 10.6 has downgraded networking speed

I have 3 computers on my 100% wired Gigabit network at home. All 3 computers are connected to the same router.
1 is a linux machine, 1 is a Macbook (C2D 2.4GHz 4MB RAM) running Leopard 10.5.8, and 1 is my iMac (C2D 2.4GHz 4MB RAM) running Snow Leopard 10.6.1. Both iMac and Macbook have identical specs and RAM, only difference is one is running 10.5.8 and one is running 10.6.1.
Prior to upgrading my iMac to SL, I'd consistently get between 10-20Mbps download result using dslreport.com speedtests. I'm on Comcast. Now after upgrading to SL on the iMac, I can only achieve around 2.5Mbps maximum speed test results. I performed this test 5x over several days to make sure there wasn't some coincidental anomaly. As a test I performed the same speed test on the Macbook and it indeed hit above 15Mbps speed result consistently 5x in a row and over several days. My linux machine also achieves the same 15+Mbps speed result.
I've tried tweaking the iMac's SL network settings, but nothing helps. What has happened in SL to degrade network throughput? I can clearly and consistently reproduce this issue.

Aha! I've found the problem. Its the Flash 8 speed test that is the problem on SL. When performing the same speed test using the Java speed test, I achieve the 15+Mbps download speeds.
Flash 8 speedtest
Sun Java plugin speedtest
I've done the test 5 times in a row and I get the same results form each respective speedtest type.
So the problem is what is wrong with Flash on Snow Leopard?

2007ish IMAC upgraded to Snow Leopard, almost not functioning at all...

I have an Imac 2006/7 I upgraded to snow leopard and it has been froze up ever since. Called Apple, they said buy RAM I did, installed it. Still freezes. After trying to click around I eventually get a message "Your Mac OS x disk has no more space available for application memory" To avoid problems with your computer, quit any applications you are not using. Closing windows and removing files from your start up disk, will also help" Any thoughts?

For the trash, try restarting and then attempt to empty.

I have a mac book 10.6.8 that has been upgraded to Snow Leopard (latest version.) How can I upgrade to mountain lion with 1GB of memory? When I go to buy it, it says that it's not compatible with my Mac but my Mac has all of the qualifications.

If anyone has any idea I'd really appreciate it. I just bought the iphone 5 and recieved the new nano as a birthday gift and now I'm up a creek without a paddle b/c I can't plug them into my laptop without the new itunes that runs on Mountain Lion.
Please help, I'm not very tech savvy.

You don't need anything higher than OSX 10.6.8 to run iTunes 11. iTunes system requirements - http://www.apple.com/itunes/download/
You can't upgrade without more RAM.

Open General preferences in System Preferences. You can set the desired scrollbar behavior there.

HT6012 I had an older version of Mac OS, I upgraded to Snow leopard and then OSx Lion, most of my software has been upgraded except for Imovie. Now I can't get my projects to upload or share to iDVD or iTunes. What do I do?

I had an older version of Mac OS, I upgraded to Snow leopard and then OSx Lion, most of my software has been upgraded except for Imovie. Now I can't get my projects to upload or share to iDVD or iTunes. Also to compound the situation everytime I attempt to share to iDVD or iTunes, iMovie quits unexpectedly. What do I do?

If you want to sync it to the iPad from that Mac, you need to upgrade it to at least 10.5.8.
If you want to copy the music to another Mac, you don't. Move the iTunes folder of the item in the Finder's sidebar over as you would any other folder. If you put it somewhere other than the Music folder, launch iTunes with the Option key held down and point it to that location.

The installer is over 5Gb's and could take many hours to download.
Check the download status in the App Store application.

Recently safari has been quit unexpectedly I've upgraded to snow leopard and I have the latest safari software. What can I do about it to rectify the problem?

Recently Safari has been quitting unexpectedly. I've dumped my cache several times and even upgraded to snow leopard.l I have the latest version of Safari 5.0.5. The situation has gotten quite annoying and been going on for about three weeks now. What can I do to fix this short of bringing it to someone?
I restart and it works fine for awhile and then it quits again. I either restart and/or dump the cache AGAIN! This is getting quite tedious. I've even taken the battery out and reinstalled it. Nothing seems to stop the quitting.

It looks like your MacBook Pro is restarting. Just hold the Power button until your computer turns off, and then turn it on again, so OS X should start properly

Upgrade to Snow Leopard has killed wifi usability

Upgraded to Snow Leopard a couple of days ago and it has significantly impacted my ability to use WiFi, tried on 3 different networks; 2 personal and one carrier and I am either unable to connect or the connection falls out after a few minutes, and when it works the speed is significantly regraded.
Prior to the upgrade I've never had a problem on these or any other wifi networks. Have tried all the proposed solutions I've found on the discussion forum but nothing seems to permanently resolve the issue.
Looking for some new suggestions or a solution from Apple. Being tethered via an ethernet cable seems so old school!

I seem to be having a similar problem but the only option I have is automatic channel selection.
I have a mini with a quickertek nCard in it running at 5 Ghz. Under Leopard I could move it downstairs and everything works great. As soon as I upgraded to Snow Leopard it would no longer work downstairs (signal shows full strength though) but will still work upstairs. Something in Snow Leopard is interfering with performance of the 5Ghz band at a distance. Very frustrating. My only option now is to get the latest Airport Extreme and hope it does better because of its 802.11n at a distance improvements.

I am new to mac's and have upgrade from Snow Leopard to Lion but......

I am new to mac's and have upgrade from Snow Leopard to Lion but not all my application will work. Is it save to reinstall using original snow leopard dvd and does it wipe all my other application like apature? I am in a panic over this, any help!!
I came across this online and i want to know is it safe to do this:
Backup your User folders to an external drive. This should preserve your documents, photos, music, etc. If you store those things in locations not in the User folder, make sure to copy those over too.
Insert the Snow Leopard disc. Restart your Mac and hold down C to boot to your DVD drive.
Go to Utilities in the menu bar once the installer pops up and select “Disk Utility.”
Find the drive in the sidebar where Lion is installed, select it and navigate to the Partition tab.
Click on the drop down menu under Partition Layout and select “1 Partition.” Hit Apply.
Now navigate to the Erase tab and make sure “Mac OS Extended (Journaled)” is selected, then hit Erase to delete all data on the drive.
Quit Disk Utility to get back to the Snow Leopard installer and proceed with the install.
Restore your User folder and documents from your backup.
Run Software Update to get everything current, install your apps from your original install media and update those as well.
if any one can help me that would be great, thanks Mike

Before you do that why not do this first:
Repair the Hard Drive and Permissions
Boot from your Lion Recovery HD. 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.
To boot from the Recovery HD restart the computer. After the chime hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
If this doesn't help, then you can proceed to reinstall Snow Leopard as follows:
Downgrade Lion to Snow Leopard
1. Boot from your Snow Leopard 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.
2. After DU loads select your 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.
4. Quit DU and return to the installer. Install Snow Leopard.
This will erase the whole drive so be sure to backup your files if you don't have a backup already. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard. I suggest you make a separate backup using Carbon Copy Cloner 3.4.1.
This will erase the drive so be sure to backup your files before doing this.

Cannot upgrade to snow leopard

I have a late 2007 iMac (2GHz core 2 Duo). Since I purchased it, it has run Tiger, then Leopard flawlessly. I recently bought a Magic Trackpad which required me to upgrade to Snow Leopard. Unfortunately, 10.6 seems to kernel panic almost as soon as it boots up. If I downgrade back to 10.5, all works fine again. I have tried the following:
1. Clean install of 10.6 = kernel panic once the OS boots
2. Clean install using another 10.6 installation disk = kernel panic once the OS boots
3. Swap out RAM = kernel panic once the OS boots
4. Boot from an external 10.6 disk = kernel panic once the OS boots
More often than not, I can boot into safe mode with Airport disabled although sometimes (seemingly random) that also kernel panics. I am completely stumped here and would appreciate any help please. I don't want to be stuck in Leopard for all eternity! BTW I did take it into the Apple Store, and the "geniuses" claimed it was fixed - took it home and it wasn't. Below is the output from the kernel panic log:

Are you trying to boot off a 10.6.5 updated system, or a 10.6.5 installer DVD from another Mac? According to;
http://en.wikipedia.org/wiki/MacOS_X10.6
The build and Darwin version belong exclusively to 10.6.5.
Your Mac can only boot off 10.6 and 10.6.3 retail to install 10.6, as well as systems upgraded from those 10.6 installations on your specific model and vintage iMac. But it can't boot off another Mac's installer. The 10.6 installer DVD must look like *
and not say Upgrade, Dropin, or OEM.

My Creative SBS250 speakers no londer work after upgrading to Snow leopard. Where can I find the driverinstalling

My Creative SBS250 speakers no longer work after upgrading to Snow Leopard. Where can I find the driver? Thanks

Everyone in my household who has upgraded to Snow Leopard has had the same problems with program crashes and the computer "forgetting" registration codes.
In fact, after re-entering codes, and then upgrading to 10.6.1, we had to re-enter them again because it forgot (again) that we had bought/registered the software. It was a lot of fun digging through old emails and such looking for the codes, let me tell you.
I'm pulling a Vista and downgrading my computer back to 10.5.x. That was stable and remembered my software, at least.

Applications fail to work after upgrading to Snow Leopard

I can't believe how poor a job the upgrade is! Ok, Snow Leopard installed ok and saved me a good bit of space. It also boots a lot quicker too. But.....
..what is the point of all of this if it no longer opens my applications without crashing every time??! I wouldn't mind if they were old but the apps are mostly the latest versions, and are even Apple products too! E.g. Final Cut Pro.
Also, the apps that do open are now asking me for the registration codes all over again. If this was meant to happen then a heads up would have been nice
Apple.
I would prefer the slower Leopard with all my apps working than this upgrade where I can't do anything!
What kind of upgrade do you call this Apple??? I hate to say it but Microsoft might well have done a better job! Will Apple be resolving these issues soon?
Any one else having problems with applications?
Anyone found a solution?
Anyone know how to backout the upgrade?
Many thanks from a very disappointed Apple fan.

I upgraded to Snow Leopard, made a change to Address Book that I need to correct, tried to use Time Machine to find the prior version and it keeps pulling up the later ones info. How do I use Time Machine to restore Address Book from a few hours ago?

This morning, I upgraded to Snow Leopard from v10.5.8. Then, I exported 11 contacts from our old Now Contact database, intending to import that info into Address Book. It was an experiment, as we have 1199 contacts in 20+ categories and want to eventually get them into Bento from Address Book. The export automatically created a file called Export.vcf on the desktop, after I highlighted the 11 contacts. I tried to look at the info, but when clicked it opens Address Book, which then simply asked if I wanted to import the 11 contacts to it. I clicked yes. Then in checking Address Book 7, not 11 contacts appeared. I clicked on "All Contacts" and there were 1630. We only have 1199, so where did the extra 400+ come from? Since I had already clicked twice on the Address Book window, I couldn't undo the import. So I thought 'Ok, I'll trash Address Book and go to Time Machine, find Address Book, go to right after the upgrade to SL, hit Restore and bingo. Nope. I keep getting the post-import info, not pre. Con someone direct me to a solution? I want to get rid of the import contacts plus the extra 300 or so ( I already had a hundred or so in several categories)? Then, I need to figure out (1) why ALL the old records were exported from Now Contact, (2) where they were hiding in that .vcf file when Address Book recognized that I only wanted to export 11, (3) why Address Book showed only 7 imports in the "Last Import" group, but showed ALL my contacts in the "All Contact" group, even though they should nearly all have been safely untouched in the Now Contact DBase file. PS, I am not especially computer savvy. Thanks for any enlightenment.

1. 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.
2. After DU loads select your 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. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
7. After formatting is complete quit DU and return to the installer. Install Snow Leopard.
