About a month ago I upgraded my iMac's OS to 10.6.4 Snow Leopard. I've noticed that my computer has gone progressively slower.

 

My computer struggles to run applications like Picasa and Mail. I can run Photoshop CS5 but it takes about 45 seconds to open an image.

 

My specs (taken from System Profiler.app);

Hardware Overview:

 

Model Name: iMac

Model Identifier: iMac8,1

Processor Name: Intel Core 2 Duo

Processor Speed: 2.8 GHz

Number Of Processors: 1

Total Number Of Cores: 2

L2 Cache: 6 MB

Memory: 2 GB

Bus Speed: 1.07 GHz

Boot ROM Version: IM81.00C1.B00

SMC Version (system): 1.30f1

 

 

Applications ran fine on 10.5 Leopard, but they've just seemed to dramatically slow down.

In that search thing, type in terminal, when it opens type in ps -A. (I may be making up commands here) Copy and paste the results into a post.

Is it getting hot?

In this weather computers can overheat fairly easily especially if they are cornered in, agaisnt a wall etc.

 

I mean my system is pretty darn cool running and even that creeps up to about 40 C which causes some lag.

Open up disk utility and verify/repair disk permissions.

The top of the screen gets hot, but I think it's because I have vents at the top of the back side of the screen that let the heat out as it moves up.

 

@Laura: What exactly will that do?

@Laura: What exactly will that do?

In the Microsoft world we call it "Disc Check". It checks the Hard Drive for corrupt areas known as sectors. when you have a lot of them the Hard Drive tries to keep reading it even though its more messier then Lindsay Lohan's career. What it'll do it tell your hard drive "Stop being a dumb arse, that area's off limits to touch", so it stops trying to read dead areas.

 

TL;DR - Speeds the Hard Drive up.

So it won't delete any data or anything? I have 10-20GB of photoshop PSD's on my HDD.

So it won't delete any data or anything? I have 10-20GB of photoshop PSD's on my HDD.

Unless the data is corrupt itself, it'll just play tetris with your hard drive. slot everything it nicely into the space that isn't dead.

Have you tried doing a restart?

Many times, doesn't seem to do much.

Have you tried scanning for viruses? There aren't a lot of viruses yet on macs, but there are.

I hate to go down this road again, but there are no viruses for OS X. Only select malware - and there is a difference. Most of the AV services offered for the OS X platform only scan for Windows based devices. Hence the inclusion of the ClamAV program into OS X Server but not into the consumer addition. He would be better off by uninstalling any AV program and freeing up those processes.

 

But I also see that you have installed several constantly running programs. It might be beneficial to open up the Activity Monitor and show us the list. Afterwards, if it is clear that the software is not conflicting, we could try resetting the PRAM and the NVRAM.

laura, inform yourself. There are more and more viruses for OS X, and if you go to the store, you will find multiple antiviruses for that paltform too. Since more people are going towards Macs, more people are making viruses for it. Right now there's not much more than reinstalling to remove those viruses.

Hmm. I was hoping that would actually tell me something. But it didn't. :razz:

Looks like you're running low on RAM.

No joke. Have you ever tried iFreeMem? You have an awful lot of inactive space...

The only programs I have open the majority of the time I'm computing are Safari, iTunes and Bowtie.

Those are the only programs YOU have open. With all the background processes your computer is running, you're running out of RAM.

Alright, so reboot your computer and immediately, before doing anything, open up Activity Monitor and take a screenshot. Then post it.

Yup, the best upgrade you could do for your computer would be to upgrade to 4GB of RAM. It's alright when you first boot up, but as soon as you load up iTunes, Safari, etc, space is going to get a little tight. That's probably what you are experiencing as a slow down.
