Why is Safari running so slow under Mountain Lion?

Why is Safari running so slow under Mountain Lion?

I have other mac's on my home network that are still running Snow Leopard and the are performing well. I wanted to use the iCloud so I upgraded and instantly started experiencing the slow down, to the point of ridiculousness. Other function are mixed some normal speed, others a day on the beach with the spinning ball. Firefox is at full speed, good thought, haven't checked Chrome yet.
Last night and hooked into a projection unit that adjusted my screen resolution for a presentation and after the event my Mac reset back to the normal settings and Safari launched and is running normal speeds so far. In the past there have been issues with performance speeds and certain resolutions, has anyone had similar luck or is this a fluke?

I have a 27in. i5 2011 iMac. Since downloading mountain lion, I can't print or scan, using an Epson AIO Artisian 835, plus I can't do upgrades. and of course I lose wi-fi. I think if I could do upgrades, I could fix the print/scan problem. Any ideas?

I've had several problems since downloading Mountain Lion. As with many others, I lose wi-fi on wake-up. I've also lost my ability to print or scan and I can't do upgrades. If I can't fix these issues, can I uninstall Mountain Lion and go back to Lion?

What is wrong with your Mac? You still haven't told us what the problem is. Is the computer still under warranty or Apple Care?
the next time i attempted to use the computer it wasn't fine
What do you mean by "wasn't fine". We can't see your computer so you'll have to describe what your're experiencing in detail without the editorializing.
Download and run Etrecheck. Copy and paste the results into your reply. It's a diagnostic tool that was developed by one of the most respected users here in the ASC to help identify the more obvious culprits.

Try restarting your router, but I will need more info like how are you trying to connect wi-fi, Ethernet, type of connection cable or DSL what type of router Apple, Linksys.

After downloading OS X Mountain Lion, my mac has become very slow

After downloading OS X Mountain Lion, my mac has become very slow and takes a bit to shut down programmes. What can i do to bring it back up to the speed it was when i had OS X Lion

Though I wish it were true, it is unrealistic to put 200+ new features into OS X and expect Mountain Lion to run faster and more efficient than Lion on the same hardware. I moved up from Lion to Mountain Lion. Mine is slowing down, but not very slow, as you mentioned. Safari and Mail are simply swine on launch. Check the following:
Patience. If you are impatient and detail alters your mood, take your MBP to the Apple Genius bar.
CPU. If you have a supported, but older MBP, your CPU may be showing its age.
Memory. 4GB or 8GB in your MBP? Mountain Lion drinks more than Lion and if you run multiple large memory footprint applications, 4GB will be a performance bottleneck. My HD3000 graphics takes 512MB. Check the System Information report for your memory. Is it OK?
Compatibility. Sometimes, hardware peripherals and applications are not entirely compatible with a new OS release, and divert OS performance to system log entries. A symptom is a large (> 2GB) system log file at /var/log/system.log. I just discovered a bad USB hub this way. Unplug everything and evaluate your performance again. Zero [ # > /var/log/system.log] the log file if you have the permissions.
Permissions. Launch Disk Utility and verify/repair Disk Permissions on your Mountain Lion disk. While there, might as well Verify Disk too.
Preferences. Sometimes, older preferences do not play well with upgraded application compatibility for a new OS release. It might be worthwhile to delete the specific preference and its lock file from Lion.
Caches. As routine, just before I shutdown the system, I will move the contents of /Users/name/Library/Caches to the Trash. I tolerate Adobe Flash and use their preferences panel to delete all Flash content. Then on reboot, I delete the Trash. Application performance improves as a result.
File Directory. Everytime that I upgrade OS X and run the retail Disk Warrior 4.4, it reports 25% storage fragmentation. Repairing and rebuilding the File Directory always restores noticeable I/O performance.
Storage. If within your budget, upgrade to an SSD. Otherworld Computing has MBP SSD solutions.
Applications. Some non-Apple applications may need recompilation for Mountain Lion, or behavior may be questionable. I compile my own MacVim editor from github sources. The same 64-bit binary that was compiled with XCode 4.3 on Lion, misbehaved on Mountain Lion. Rebuilt it with XCode 4.4 and worked fine.

My MacBook running Mountain Lion does not allow me to view any videos on the Internet. The place where the video is supposed to be just shows black rectangle. Is there anything I can do to make videos on line work?

My MacBook running Mountain Lion does not allow me to view any videos on the Internet. The place where the video is supposed to be just shows black rectangle. Is there anything I can do to make videos on line work? I discovered that Java quits immediately. Could that be the cause? If so, how do I fix it?

I downloaded mountain lion on my laptop. Do I need to do the same on my Desktop and iPad or is the one download good for all 3, and how do I do that if it is?

I downloaded mountain lion on my laptop. Do I need to do the same on my Desktop and iPad or is the one download good for all 3, and how do I do that if it is?

If your desktop computer is one that supports Mountain Lion, you can either download it there or make a bootable jump drive with the installer on it -- assuming you haven't yet used the installer you downloaded to your laptop.
As for the iPad, it doesn't use the same OS as the Macs do; it uses iOS versions, so Mountain Lion won't work there.

need help

First boot into recovery and select Disk Utility>First Aid and repair the disk.
If there is no improvement, perform a Safe Boot:

If there is an improvement, then third party applications are probably the cause of the problem.
Ciao.

HT4718 I want to do a factory reset on my iMac due to problems I have had since downloading mountain lion. Should I install my original mac disk (snow leopard) or will it reinstall mountain lion automatically?

I do need mountain lion so I can use icloud. When I downloaded Mountain lion I couldn't find any of my docs because (as it turns out) my hard drive was split and so now everything is in sepperate places and I cant find bits etc. So....... I want everything to be in one place, easy to use as before. I have everything backed up to an external hard drive now.

Install or Reinstall Lion/Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Erase the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your startup volume (usually Macintosh HD) from the
      left side list. Click on the Erase tab in the DU main window.
3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
        the Security button and set the Zero Data option to one-pass. Click on
      the Erase button and wait until the process has completed.
4. Quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion/Mountain Lion and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
            because it is three times faster than wireless.

Why is iTunesU running very slow on Windows 7?

iTunesU is running very slowly on machines using Windows 7 and iTunes 10. It works fine on Windows XP withe iTunes 10. Why is it slow in iTunes 10 and Windows 7?

Yes. It does seem to be specific to 10.2.2 Other versions are working fine. In windows XP 10.2.2 has not given me any problems. But on Windows 7 it appears to be frozen for about 5 minutes then it starts working but it still lags. Are you Apple people going to address this? Is this something that can be fixed with another update?

Hello. I am using MacBook Air. Safari is very slow and it doesn't open many websites. for instance: dizi-mag.com . please help me

Please answer as many of the following questions as you can. You may already have answered some of them.
1. Have you restarted your router and broadband modem since you first noticed the problem? If the answer is no, do that now and see whether there's any change.
2. Are any other web browsers installed, and are they also slow?
3. What about other Internet applications, such as iTunes and the App Store?
4. Are there any other devices on the same network that can browse the Web, and are they also slow?
5. If you can test Safari on another network, is it slow there too?
6. If you connect to your router with Wi-Fi and you can also connect with Ethernet, do that and turn off Wi-Fi. Any difference?

Since downloading Mavericks last week my Mac is very slow. Anyone else having this problem? Any suggestion as to speeding things up?

It will help people help you better if you post your iMac variant and Mac OSX version. Please do "About this Mac" from your Apple menu and, in the resulting window, click the "More Info" button. That will give this window:
The model is in the line I've indicated with the red arrow. Please also post the results for "Memory" and "Processor."
DO NOT post the serial number, however.

Safari running very slow after downloading Mountain Lion

Since downloading OS X Mountain Lion Sarfafi runs very slowly as though I have used up my data download allowance from my service provider. I have no proxies installed (not that I would know what this means) and the DNS entries are from my service provider. Is there any way to uninstall Mountain Lion so I can have my imac back to the way it was??? I really regret downloading it. on top of that, whilst it shows I have downloaded an app (mountain lion) on the App Store icon, it doesn't come up when I click on it.

If you're using iCloud, disable all its services and test.

Since upgrading to Lion why does Safari freeze when using an email link?

I have a 21.5 in iMac (purchased late 2009). Ever since I upgraded to Mac OS X Lion 10.7.2 I have had problems opening links from my email. Safari is my default browser, and now I when I open a link from my Mail, the browser functions do not respond. The page freezes and does not allow me to scroll at all, nor will any of the links work for me to click on what should be an active link. When I open a new browser page, it is fine--whether Safari, Firefox or Chrome. It's just when I open from Mail.
Anyone else reporting this, and is there something I need to change to make it work? I'm not very technical with the Apple products...thanks!

Thanks again but I have no peripheral devices connected. It's very annoying whenever I close the lid the logo stays lit and the computer does not go to sleep (light on front stays solid white). Each time it happens I have to open and close the lid 3-4 times before it finally goes to sleep. It's as if the computer gets hung up trying to go to sleep.

Since downloading Mountain Lion, why is Safari running very slow? I've check the internet and it's fine.
