Brand new iMac: super slow web browsing

Brand new iMac is super slow while browsing the web.
We have cable internet, and the iMac is connected via ethernet cable to an Airport Extreme router. We have a Windows machine connected to the same router.
The Windows machine loads web pages extremely quickly, the iMac takes 20 seconds to a minute to load anything.
Clearly there is a settings problem on the iMac. No idea what.
It isn't the router.
It isn't the broadband connection.
It isn't the DNS server.
Please help!

I'm not sure if you understood my original post, however, I will re-iterate it here.
I have several machines connected to the same network.
MacBook Pro
Windows machine
iMac.
Only the iMac exhibits any problems.
Clearly, the ISP is not the issue. The iMac is connected via Ethernet to the same router as the PC.
Clearly the Mac is the problem.
Changing DNS server has no effect.

Brand new Yoga 2 11 - Super slow web browsing

We got a new Yoga 2 11 this morning, and the web browsing is excruciatingly slow, whether using IE, FireFox or Chrome. The only downloads or installs of any kind have been IE & FF.
Based on searching this forum, I increased the minimum processor power to 65%, but that was only an incremental improvement. Some page loads are still taking over a kminute, and an attempt to proceed with a page that isn;t full loaded (i.e. a login), just crashes everything. I ran SpeedTest, and the download and upload speeds are all 3x that of my work machine (a Latitude that is about three years old)...but the Latitude has "normal" load times.
The only other observation I have is that it seemed better behaved before the Windows updates were applied, but there was maybe only 15 minutes of use there, not enough to reliably establish a baseline.
Does anyone have any suggestions for what I might be missing? This might be going right back to the store, as it's not really an inprovement over the 3 yr old Asus netbook, which is less powerful than most phones...

Well in general, Ideapad computers have driver issuess.
If you like we can try teamviewer and try to fix your issue.
Teamviewer does not need to be installed. It will give me temporary access into your computer to fix the issue. When the issue is fixed, simply delete the program. Anyhow, once you close the program, the password is reset and the ID blocked until next launch. I also figured a 1 day old computer has nothing important on it. So if you like, I can try to eliminate the hassle for you and try to fix the computer.
Should you feel uncomfortable with anything, you can close the program at any time.
Based on the speed test, I doubt it is an internet problem. I am thinking software problems.

Why is my brand new iMac so slow?

Hi,
I bought my iMac about four months ago. Never had a Mac before and I'd been looking foreward to it
for a long time!
Specs: iMac 27" | OS X 10.6.8 | quad core | 2.7GHz | 4 gig ram | 1 TB disk | 1333 MHz | DDR3
Very early it striked me how slow this machine was! Starting and rebooting is insanely quick, but
that's about it! I work in Photoshop, and it is just horrible. It crashes all the time! I am used to work
with several layers, I can't do that here. Because it's sooo slow...
I also work in a 3D program called ArchiCad and this is even worse! I've had to teach myself a
slower workflow to prevent it from crashing. I hate it...
If both Photoshop and ArchiCad is open at the same time, the Mac crashes VERY fast. I have to force quit app's
and reboot the Mac often. Sometimes several times in one day.
I see this little circus wheel all the time and it's driving me nuts!
Sometimes the Mac just crashes without having lots of apps open. I might have a couple of browsers open,
a word document, finder and a priview. And it crashes!
And I have to do the eternal job of force quitting and trying to tell the Mac to reboot. This often takes a while.
The Mac is full of small problems also.
- I have to install the magic mouse all the time! It just gets lost and I have to use my track pad
to search for it. Even though the batteries are new. Sometimes this only happends once every
second week, sometimes it happens 15 times a' day.
- Sometimes I can flip between pages in web browsers by swiping with the mouse, sometimes I can't.
Sometimes I can do this when working with folders, sometimes I can't.
- I often have problems with Java.
- The web browser Opera crashes all the time. Can't use it.
- Sometimes, videos from f.eks youtube can't play.
- Just opening a photo in preview can take 10 seconds! Not allways, but sometimes.
- Using cover flow with images is useless. It uses so much time to preview the photos with good quality.
You might wonder, what have this dude done to his Mac?
I have installed Photoshop, ArchiCad, Chrome, Opera and a small app for browsing an old iPod touch.
That's it!
Since I'm a photographer I've also put a lot of photos here, but not more than perfaps 100GB. Max!
I am very, very carefull with what kind of websites I visit. I never visit a website I don't trust.
I don't download anything (movies, games etc). Everything I have is original. No pirate.
So I brought it wth me to my local apple store. They thought it was a problem with the disc.
After being without the Mac for a week they told me nothing was wrong with it. It was perfect they said!
My jaw dropped all the way to the floor.
All they could say was that I could format and reinstall the intire system and/or upgrade to 8BG ram.
Do you guys think this will help? Why should I reinstall? I can't understand how I could've screeved the system up!
And really? I should use MORE money and upgrade to 8gb Ram? My previous 2gb Ram PC was so much faster! Is this necessary?
I hope someone can give me any advice.
I feel lost. This is by far the worst purchase I've ever done. I hate my Mac...

Well,
To start Dan, you are using quite a few CPU, GPU, RAM and HD intensive apps.
4 GBs of RAM isn,t going to cut it. 8 GBs isn't going to cut it! Not at all! 4 GBs Of RAM is the base (read minimal ) RAM the iMac model you bought comes with. It doesn't mean it's enough to run lots of Applications. Epecially processor intense applications you're trying to run!
Every re-iteration of OS X uses more and more CPU, GPU, RAM and HD resources.
OS X, BY ITSELF, needs between 2-4 GBs of RAM just to do its things smoothly.
Using Photoshop alone needs oodles of CPU, GPU, RAM and HD space for scratch disks.
If you are a seasoned Photoshop/Adobe user, you should already know this fact!
ArchiCad is another, CPU, GPU and RAM heavy app.
You have various browsers, email, word documents open simultaneously? Really?
More than one web browser open? Web Browsers also eat up lots CPU and GPU cycles and RAM!
The thing that eats up CPU, GPU and RAM cycles with web browsers is Adobe Flash and to some extent Java.
You're trying to run all these thing on very little to no RAM horsepower!!!
You're asking your iMac to run all these heavy processing apps with no additonal RAM available to do so.
As you've discovered, this is not working.
You're probably getting a lot of page in/outs and virtual memory swapping between real RAM and the hard drive.
You need to install, AT THE VERY LEAST, 12 GBs of RAM! I would just install 16 GBs of RAM and be done.
Your iMac can take up to 32 GBs of RAM, but this, I think maybe overkill. Try your system with 16 GBs first.
I have a 2009 27 inch iMac with 16 GBs of RAM running CAD and Adobe CS 3 and Blender 3D and other processor intensive apps with very little issues.
Buy reliable RAM from online sellers Crucial memory or OWC.
As wise advice from me, if you want to experience a smooth and productive Mac experience, do not upgrade your iMac to 10.7 or 10.8.
10.6.8 Snow Leopard is the last "real" version of the previous Mac OS X versions that many of us still love and use. Newer versions of the OS, basically, still have many issues and turn your iMac into a giant iPod, iPHone or iPad., Instead of being a fully customizable and reliable OS.
The magic mouse is really a crppy mouse to use with drawing and painting applications like we both use.
Ditch it and purchase either the old RF style Mac compatible wireless laser mice or purchase a wired mouse.
These mice are more accurate pointing and tracking devices.
Look at Mac compatible mice models from Microsoft, Logitech, Kensington or Apple
The battery life of the magic mouse is just poor, also. Its tracking is poor for fine mouse movements, too!
Does your wireless trackpad work any better? Is it better on baterries? Do you get fine control using it?
If the trackpad is better, than just ditch the magic mouse all together.
If the trackpad give you trouble, too, ditch it for a more accurate mouse, trackball or trackpad from another manufacturer other than Apple. Again, Mac compatible trackpads from Microsoft, Logitech and Kensington.

Brand new iMac running slow with only 3% of HD used!

I just purchased a new iMAC 21.5" with 2.9 i5 and 8GB memory and literally have yet to add any programs except AI, ID and PS and its running very poorly. This is my first MAC and i'm very disappointed. I purchased this computer for school where I am getting my BS in media arts. I use an older 27" iMAC at school using all the same programs and more and my new computer doesn't hold a candle to its usability. For example, opening up the programs takes what I consider to be a long time being that there is nothing on the HD. While in PS, and trying to edit, without even having multiple windows open, or multiple layers, it will not instantly edit in the preview window. If and when it decides to edit the computer, then it prompts the color wheel buffer. I specifically told the guy at the store exactly what I would be using it for - to only run the Adobe programs and CC. Since owning the iMAC, I have updated the suggested programs from the apple store and had the most recent OS updates.
The model number of the computer: A1418 any help would be greatly appreciated! If I don't have the correct model I need - I will gladly make the unsaid large retail giant take it back, one way or another.

Mavericks on brand new iMac is very slow

I have a brand new iMac with the basic configuration and the latest version of Mavericks. I use iLife, iWork, Photoshop, Office, Dropbox and Mailplane as the main programs but it is very slow. I did not restore from a Time Machine backup and installed all programs and files separately but I often get the beachball and the computer is often very slow, it also takes a while to start up. Is there any way to see what is slowing everything down?
When I look at the activity monitor there are hundreds of processes but kernel_task always seems to be using 700mb+.
Any ideas would be hugely appreciated.

Hi, thanks for helping. Here are the results from your program.
In response to the other poster's question the beachball happens with iMOvie, iPhoto, Mailplane and photoshop.
Thanks..---

How do I uninstall Mavericks and recover Lion? I have a brand new iMac and web pages stall or freeze since I installed Mavericks. I can't get it to download software for my printer when I connect it.

I have a brand new iMac. It was working fine until I downloaded Mavericks. Now I have web pages that freeze while trying to load. The blue in the address bar stalls and freezes. If I try to load from page 1 to a later page, or reverse that, I also have the same problem. I tried to connect my printer for the first time, and again, the blue progress bar froze. Then I got the yellow triangle telling me there was a connection problem. My internet connection is via an Air Card as that is my only option where I live. I packed up the whole new iMac and took it to my Air Card provider, where they also have very fast Wifi, and they had the same problem with Wifi. I use my Air Card with my MacBook and it works JUST GREAT! I really want to return to Lion. HELP.

The only way to retutn to Lion is to format your drive (erase, lose all) and either:
1. clone back the clone copy i hoep you have, or
2. first backup your files, then format and install Lion again
But really, mavericks works great. You have a problem. Find out why. First, what unusual software do oyu have installed that may be conflicting with it? Virus, system modifiers, etc? Second what OLD software do you have that might be the problem. finally, you might need to do a re-install if something errored during install.

Photoshop CS6 keeps crashing. I am using a brand new IMAC, I have 16GB RAM recently updated as it was running slow with 8GB and lots of hardrive space. When it crashes, i lose all my presents and it changes my preferences, it also fails to save or produce a recovered file despite settings asking it to do so every 5 mins now. When i try to report the problem, it says it has found an issue and gives me a link to a solution....but wont let me click on the link.... PLEASE HELP! It's killing my productivity.

If the crash started right after you added RAM, it could be a bad Ram dimm. You can try this - change the amount of RAM in Photoshop to 4G, this should stop Photoshop from using the higher ram. If it doesn't crash, it's probably the ram. Or run a diagnostic app. You don't say when it crashes, what you're doing when it crashes - it there a pattern? Did it ever work on this computer? Did it work on your previous computer? Without a lot of data, it could be related to the new computer... What OS version? Did you recently update it? Have you updated Photoshop to the most recent update?
Do you have any plug-ins loaded? Try restarting Photoshop, and immediately press & hold the shfit key to turn off plug-ins.

Slow performance, brand new iMac!

Hello!
First, excuse my rusty English.. I hope you manage to read it
Main problem.. Adobe, PhaseOne and other intensive applications is veeeery slow on a high specced brand new iMac! Lightroom 5, PS CC and Capture One Pro 7 is what I use mostly.
I just got my brand new iMac 2014.2 (3.5/3.9 GHz, 32 GB RAM, 512GB flash disk and GTX780M), and its quite a lot slower than my other Win7 workstation. Other workstation specs: i7 4.2 GHz, 16GB RAM, 128GB SSD, GTX 580. I'm working on the same Raid-5 drive (USB-3) too, so I don't know why it's slower..
What I experience:
Changing from "current" raw to next raw (while culling) takes several seconds, and my Raid-5 is done chewing long before I see the result on my monitor. I get the spinning beach ball while waiting for preview. I always render 1:1 on import and 1:1+standard size in menu, just to be sure. Adjustment brush is like dodging in PS v1.0 (NOT CS) when computers had less disk-space than we have cpu-cache today, awfully slow, and it "stutters". Moving/panning in 1:1 is very choppy, and sometimes I get the spinning beach ball while panning.. This happens in LR and CO.. Photoshop CC stutters or have to "think" when I try panning. These problems happens in 6 Mpix, 12 Mpix or 25 Mpix RAW files, and actually in some JPEGs too!
I have done following:
I've tried 2003 and 2010 processing in LR, small change. Fixed permissions in OS X. Removed preferences for LR, CO and PS CC. Reinstalled LR/cloud apps and Capture One Pro 7. Increased camera raw cache from 15 to 50 GB. Followed Adobe's guide to make LR faster. Followed Capture One guides. Reinstalled (clean install) of OS X. I've tried all tips I could find in the forums around.. I have also tried placing RAW files on internal 512 GB disk to see if that helps on performance, but no change. Same story with camera raw cache, doesn't matter where it is.
Additional things.. I’ve also diagnosed the iMac with checkdisk, memcheck, logs, etc.. No problems as far as I can see.
I just changed my workflow from Win to OS X and I depend on this to work.. I currently have 4000 files from my last job waiting to be worked on, and I'm not finished until Christmas in this tempo :-(
If I can't get this working very soon, then I have to return this very expensive iMac and buy a new PC again..

Brand new iMac running very slow!

I just purchased brand new iMac on January 2nd (the specifications are below). The computer seems to be running very slow just doing normal everyday tasks. I have barely even used the computer and the only installations I've done where the ones recommended from the app store. I saw I had an itunes update the other day and went to install, the computer sat there for 5 minutes before it did anything. After it installed the app store still had the badge icon #1 next to it as if it never installed. During the installation I was listening to pandora, I tried to turn down the music and it took about 45 seconds before it turned down. I finally tried to log out of my account and it took over 2 minutes to log out.
I haven't had the opportunity to mess with anymore since yesterday. I feel a brand new computer like this shouldn't be running this slow. Does anyone have any suggestions? I will probably be contacting Apple Support after I get off work and maybe even exchanging the computer for a new one.
21.5-inch: 2.7GHz
Specifications
2.7GHz quad-core Intel Core i5
Turbo Boost up to 3.2GHz
8GB (two 4GB) memory
1TB hard drive1
Intel Iris Pro Graphics

If you are referring to this icon for the App Store:
the red numeral 1 is to tell you there is an update available. It may even have started to download, and been paused.
As far as your Mac's performance goes the Apple Store is the place to take it. You have paid for a one year warranty, and of course there is the option to return it within 15 days. Good luck.

Finder is really slow ( 15 sec.) after mavericks update on brand new iMac 27" WITH fusion drive...

When looking up files it's fine, but when trying to save or open anything through ANY program, i.e. Adobe CS6 programs, Microsoft Word, but also Apple software, finder is really slow (15 sec. or more of the same spinning beach ball) after the OSX Mavericks update on my brand new iMac 27" WITH fusion drive... This ***** really bad because it totally disturbs the smooth workflow I bought the iMac for in the first place...
Any suggestions?
Already tried 'clearing the plist file' through terminal; didn't work... Rebooting (obviously), didn't work.
Will there be a fix soon?
It's costing me way to much time waiting for the finder to show it's content when working.
Any official word from Apple on this?

I had a similar problem. Tried repairing disk permissions, tried cleaning up with onyx and applejack with no luck. Finally what did work was simply starting up in safe mode (hold shift key down after restart) and it sorted itself out
Hope this works for you

LR 5 running extremely slow on a brand new iMac

Hi, I just got a brand new iMac (specs will be attached on bottom) because my old pc was slowing down. I downloaded the CC LR and PS trials so I can see how the machine works, figuring it would be way faster then my old one (2009 machine, specs also on bottom). Unfortunately, LR is running much slower on my new machine and I am quite frustrated since I only bought the iMac due to performance issues with my old machine. I am hoping that it has to do with the setup and am hoping someone here can help me figure it out, or I will have to return this machine.
I really wished that I could talk with customer service, but that seems to be not an option, which makes me quite disappointed with CC and Adobe. I have the Scott Kelby LR5 book and set preferences up the way he did, but maybe I am missing something that he is not talking about. I have used LR since version LR3 and have not had any issues with it on my other machine, besides it slowing down now that I got a camera that produces bigger files sizes than my old.
Please let me know what other info I should supply. Thanks so much!
old machine specs where LR5 is running much faster then on this brand new one

HI this has been well discussed on the Macrumours forums and here too. Seems to be an Adobe thing as other similar software does not do this.
may be down to LR not making use of the GPU or some other reason, I'm trying to make my mind up between buying LR 5 or buying Capture One a pro 8 Which is a fantastic piece of software which does make use of GPU.
i Was hoping LR6 would come out soon (March 2015) but apparently that is just a rumor with no substance.
decisions decisions!

Why does MS Word 14.2.3 run so slow on MacBook Pro and brand new iMac?

Ever since upgrading to Mountain Lion, MS Word runs very slowly on both my 2007 MacBook Pro with 4GB RAM and a brand new iMac with 16GB RAM.
I have trimmed fonts in the systems and removed font conflicts and duplicates.
Keyboard entries are delayed by seconds and typing a document becomes a nightmare.
Any suggestions?
I have repaired permissions and verified both disks.
Also run Cocktail to clean out junk files. Still no luck.

Word is up to version 14.3.1. Try updating and see if that helps. The newest version may be more ML friendly. I certainly have no complaints about the speed of MS Word.
p.s. Just checked for updates - there is now a 14.3.2 version.

Slow Wi-Fi on brand new iMac

Hey all,
Recently just purchased a brand new iMac, very excited as its literaly my first Mac computer ever.
However, when I switched it on and started playing with it, i realised the speed of Wi-Fi is atrocious, compared to my windows laptop sitting next to me.
Some trouble shooting that i've performed already:
Changed locations
Disabled ethernet and firewire
Changed DNS
Resetted modem
Any more suggestions and help would be great!

Try a different Channel on Airport.
Open Airport Utility /Applications/Utilities
Select the device on the left then click Manual Setup.
Then select AirPort from the menu then select the Wireless tab.
Try Automatic. If that doesn't help, click that pop up menu and try another channel.
Then click Update.
Congrats on your new iMac !!

New iMac very slow? why?

Hi,
I have recently bought brand new iMac 21,5" 2,7 Ghz i5 with 8GB ram and 1 TB memory. I have transfered all data from Time Machine backup. And my computer is very very slow with apps, expecialy when it wakes up from sleep. I turn on safari, illustrator and photoshop and it takes 10 minutes to became normal. If I open mail it is very very slow. Also, twitter app. I don't know where the problem is. It is brand new computer. It has all the power. I have checked "verify disk" and everything is ok. I have repaired all permissions, and still nothing. iPhoto is extremely slow but its just iPhoto, very bad program.
But after 5-10 minutes after wakeup iMac starts to behave normal. When Photoshop is turned on (after 5-10 min) it starts to act normal. Sometimes excel doesn't won't to turn on. Mouse icon turns rainbow circle and nothing. I force quit it and start again and after 2-3 minutes it opens.
Does anybody have an idea what should i do?

Thank you. Here are info:

Brand new iMac freezes constantly! Updates aren't helping!

Hello everyone,
This past Sunday I bought a brand new iMac intel Core 2 Duo with a 250 GB HDD and 1 GB of RAM. At home I set it up with my SAMSUNG 1080p 22" monitor, Apple bluetooth Keyboard and mightymouse, and a Western Digital 350 GB HDD hooked up via USB. I was excited to finally jump on the intel-based Mac bandwagon, as well as experience dual monitors for the first time.
That was Sunday. Tuesday evening I was watching "Rome" on itunes on my Samsung monitor while surfing the web with Omniweb on the iMac monitor. All of sudden, everything locked up. I was able to move my cursor, but nothing responeded to my clicking. I hard booted the system and loaded everything I had going again, and sure enough, it locked up a few moments later. I ran system update, updated everything, then restarted. Time went by and although not immediatly, later that night it froze up on me again.
Fast forward to last nite, and the freezing reached and all time high. 5 times. Each time was when I had a browser open in my iMac window and I had Quicktime playing in my Samsung monitor. I was watching a sports program, with the player fit to the screen.
I have read many posts about intel iMacs freezing late last year, but there was a firmware update that evidently fixed that. I have this update installed, and I have had no luck. I have even contacted Apple Care via phone where I got instructed to unplug everything, plug it back in, start in safe mode, and delete cache. That didn't help me out at all. Am I right insuspecting I have a faulty Video card? I just ordered 4GB of RAM, could this be a RAM issue?

When diagnostics are run on a freezing computer and nothing shows, I'll put the program into a testing loop because this means one of two things: the issue is heat related so running the diagnostics several more times will bring on the heat so that the issue shows up or the installed RAM is marginal, just flaky enough to show up now and again but not so far off that a run through of the memory test catches it on the first run.
As I said in my original post, memory is always a suspect in a freezing or kernel panicking computer. And it does tend to top my list. But from what you describe I'm not quite willing to say, "Why don't you just wait until the RAM upgrade arrives?"
