    Looking for help from any techies out there.

    A few months back I upgraded to Snow Leopard on my Mac. Afterwards my internet speed slowed to a dial-up crawl. The network itself is fine as any other machines connected via wifi or Ethernet have no sped problems. Just the SL Mac.

    I've tried all the tips on the apple message boards to no avail. Anyone else have this issue? Any suggestions on what to look for?

    What's your setup? And what is slow? Mail? Safari?

    Yep - a year after installing SnowLeopard it now takes about 90 seconds to boot up. And the computer (not the battery) gets extremely hot. The Genius desk at Apple agrees it's a problem and they see it a lot but they don't have any solutions.

    Sort of the way it goes ...

    I had some serious slow-downs on my laptop after upgrading, but they seemed to be safari-related. That is, re-setting safari would bring things back to normal for a while. Until the next time I visited a web site with lots of obnoxious animated GIFs and Flash (e.g. newspaper front pages or any adult site.) This seemed to go along with excessive heat and reduced battery life.

    I abandoned Safari for a while, went to Firefox. Also installed a flash blocker, downloaded latest versions of any plug-ins, and waited for a couple of software updates. It seems to be back to normal now, though battery life still sucks.

    Interestingly, the slow-down happened only on my laptop, which I use for "personal" web browsing. It didn't affect my desktop machine, which is more strictly business. I suspect it was cyber-STD related, due to the diminishing difference between a "virus" and an "ad."

    I've hear many horror stories from people upgrading to Snow Leopard from Leopard

    While I decided to skip Snow Leopard altogether, if I were to update even to Lion I would both wait a few months, and do a clean install.

    If the problem doesn't go away, just copy your stuff to a portable HD and do a clean install.

    The Snow Leopard "upgrade" screwed up my touchpad, so I upgraded back to Leopard. IMO, SL is Apple's Vista.

    You should do a clean install on Snow Leopard (where you reformat your hard drive and install on a clean partition). You will lose all your data and installed programs when you do that so you need to backup everything (Try SuperDuper by Shirtpocket software).

    You could also use a disk tool like Tech Tools Pro or Disk Warrior to see if it can fix your volume. But those are expensive programs and not generally available to download for free on the internet.

    I had some slowdown when upgraded as well. I started using Chrome for my browser and it's much faster. I also use CleanMyMac regularly and run the disk utility from time to time (especially Repair Disk Permissions). My system works pretty well now and I have noticed a positive difference in the speed.

    If you are using wireless for your laptop you could also try changing the wireless channel to find one with less traffic. I switched to Channel 11 and it has increased my speed as well.

    Try starting your computer in safe mode, by holding down SHIFT when you start up. This will clear out all the caches so you can start "fresh". It may take your computer a bit longer since it has to "rebuild" some of the caches.
    Also, run Disk Utility and do a Repair Permissions on your main hard drive.
    Try that and see if it makes any difference.
