QuickTime Screen Recorder Very Slow in Mountain Lion

Is anyone else having problems with the QuickTime screen recorder in Mountain Lion vs in Snow Leopard? I remember it being light in Snow Leopard, but now, it hogs CPU and GPU (I think) cycles. Most of the time, what I'm trying to record (even just Safari or Finder windows) slows down because of it. Is there a fix for this? My computer is perfectly capable of running Mountain Lion and is much more powerful than my older Mac, which could use the screen recorder just fine in Snow Leopard.
I've also noticed that, if you choose to record audio from a mic, it doesn't start recording video until you make a detectable sound. I can tell by the bitrate meter it shows. This is stupid in my opinion... It should just start when I tell it to.

File a bug report with Apple. Aside from that, I can't help.

Time machine very slow with mountain lion

Time Machine backups seem very slow with Mountain Lion.

Same problem here. I just upgraded from Lion to Mountain Lion. I only got 19 GB of space, but Time Machine wants 10 hours, whereas in OSX Lion a full backup would take just under an hour, and incremental updates were lightning fast.
I even sat it up to do it overnight, but on 8 hours it was only half way through only 10 GB. I can't live with that in the future.
Im trying to backup on a SD card which seems to work very good in Lion. Im on a 2012 Macbook Air using a SSD.
My bite of the apple has been somewhat sour. I tried reformatting the SD card, well knowing that I would lose old backups. But still the backup is extremely slow. Now I can't install Lion or Mountain Lion from scratch without having to wait 10 hours for TM backup or installing tons of applications and settings again. Bummer. I'm never going to early adobt a OSX upgrade again.

Since Mountain Lion Upgrade is my Internet connection very slow, Since Mountain Lion Upgrade is my Internet connection very slow

Why is Safari so slow after Mountain Lion upgrade?

I have a home Optimum wifi network with Boost connecting to an Airport, with a second Airport extending, and an Airport Express extending. I have a MacBook Pro, last year's model, two iMacs, a year old each, and an older iMac. (If necessary I can get all the models etc, but I just want to express the problem). The two new iMacs and MBP are running Mountain Lion. The older Lion.
Since upgrading to ML my connection speed both over the wifi and directly connecting to the router has dropped from 30-50 down and 5 up to between 1-4 down and 4 up. I have had the cable folks here to test lines. We've swapped out the modem with a new one. I bought a new netgear N600. Everything led to the same result.
Here's the odd part. When restarting the modem and plugging it directly into the powerbook, initial tests show 30-50 up and 5 down. But once you reconnect to wifi, lose speed, the re-connect directly to the modem the slowness persists directly connected to the modem.
So I start suspecting Mountain Lion. BUT the older iMac cannot be upgraded to Mountain and is still running Lion and has the same issue. The equipment is in the same place it's always been. We've added no electronics that would be interfering with signals.
Everyone is stumped and looking suspicously at the computer and OS. Please help. I'm beginning to hear the bing bong bing bong of dial up in my head.

Apple File Sharing very slow with Mountain Lion

I've noticed since upgrading to 10.8 the transfer speeds over a LAN via AFP (File Sharing) are VERY slow.. in some instances. Based on the behaviour i'm guessing it has something to do with the amount of items.
for instance:
A folder that contains approx 122mb worth of 1500 small files takes me about 50 seconds to transfer while a long audio recording with a greater filesize of 125mb takes only 11 seconds.
using SCP from the command line the same 122mb folder took only 19 seconds while the audio took 10 seconds.
after performing the same operations on a computer running 10.6 I can deduce that the problem is on the receiving end. Audio file transfer times were the same, however the same folder of items took only 27 seconds when it was transferred to a computer running 10.6 regardless of which OS the computer sending the file was running.
apparently handling a greater number of files increases transfer time for both methods but AFP is painfully slow with 10.8 on the receiving end.
any thoughts or suggestions?
I've read a couple threads about people having trouble with Time Machine running slowly.. i wonder if this is related.

Regardless of whether you think you need it, uninstall it and test to see if the slowness problem is solved.
If it isn't put it back if you must, but there's no point trying to look for another cause till you've eliminated this one. You have a huge amount swaps which is what is causing your slowdown. 90% chance that's your AV software doing that.

Macbook Pro 2010 very slow since Mountain Lion!

Hi!
My Macbook Pro 2010 has become very slow since I installed Mountain Lion. How can I use OS X Lion again?

Formatting my HD very slow after Mountain Lion crash

Hello everyone, I downloaded Mountain Lion and everything was great. Suddenly, all my apps crashed at the same time. I couldn't even Force Quit so I decided to turn the mac off by pressing the button. After that, when I turned it on it never started the OS, what I had was the Apple Logo and a spinning icon.
I backed up some files I needed into another computer via Firewire (those files were very very slow when copied, like for 600 MB 2 hours).
Now I am trying to erase the disk so I can do a Clean Install of ML but it is taking forever. I am afraid it's a HD issue. I read this problem was caused by Sophos antivirus so that makes a little bit happier.
Is it normal that it takes so long to erase the disk? It has been like for 15 minutes.
Thanks in advance for your help guys.

It depends on what options you chose for erase. If you chose any kind of overwrite 15 minutes may not be unreasonable (certainly no on a 7-pass overwrite, but even on a single pass overwrite 15 minutes could be used up depending on the size of your disk and how full it was).
From your description, I have to say I'd suspect a HD failure rather than Sophos. Still, if you're wiping the disk we'll never know till you try to reinstall and see how you get on. If you choose to migrate from a backup, you'll have to start up in Safe Mode (hold down the shift key while powering on) to make sure Sophos gets bypassed. Actually, try 'shift-command-v' while you power on, which will show you the log as it boots up. You might get some clue as to where its hanging, if it hangs.

Mail very slow in Mountain Lion

The upgrade to Mountain Lion went smoothly but Mail works really badly afterwards.
When sending an email, it takes a few minutes before the mail goes out. And that's with any size message.
Auto-completion of mail addresses while composing takes multiple minutes. Even after it finally comes up with a list of email addresses, pressing enter on one also takes minutes to acknowledge
At various times, hitting the mail icon on the dock has no effect. The same is true with Command+TAB
Overall, the unresponsiveness is painful and making me wish I hadn't upgraded

This didn't solve my problem. First of all:
     $ ls /Library/Preferences/com.apple.mail.plist
     ls: /Library/Preferences/com.apple.mail.plist: No such file or directory
but I do have the file in my local Library:
     $ pwd
     /Users/spate/Library/Containers/com.apple.mail/Data/Library/Preferences
     $ ls -l *mail*
     lrwxr-xr-x 1 spate spate     64 Jul 26 11:08 com.apple.mail.LSSharedFileList.plist@ ->      ../../../../../Preferences/com.apple.mail.LSSharedFileList.plist
     -rw------- 1 spate spate   6733 Jul 27 08:24 com.apple.mail.plist
     -rw------- 1 spate spate 56130 Jul 27 08:12 com.apple.mail.plist.bak
This is after I moved com.apple.mail.plist to com.apple.mail.plist.bak and then started Mail again. As you can see, it created a new, much smaller com.apple.mail.plist
No luck - just as painfully slow as before!
This is horribly painful!

HP Laserjet 100 color scans VERY slow under Mountain Lion

Anyone else have this problem or a solution for speeding the process up?

Quicktime screen recording freeze up

I recently upade my snow leapard to the new Lion for the quicktime screen record and everytime I want to do a screen record it keeps froze up when I want to record. Then it takes time like when to finish it won't finish i have to turn the computer off and restarted it again. So I don't know what to do. So when i do record my hard drive makes noise when i do record. It did let me record only three but still it stops or I see a blink and it stop recording. So I just need help.
Thanks

Hey Musiclover99,
Thanks for the question. I understand you are experiencing some performance issues with your MacBook Pro. I’d like to ask you a few questions to see if we can isolate this issue further.
First, it sounds like you are trying to record your screen. Do you have a lot of applications running while attempting to record your screen, or an application that requires a lot of memory? Does the issue persist if you attempt to screen record something else?
You can use the steps in these resources to help isolate the issue:

Quicktime screen recording error.

Hey, I was wondering if there is a fix for Quicktime screen recording, because almost everytime I use screen recording, Quicktime crashes within two minutes. Before mountain lion quicktime was fine, but now the screen recording doesn't work, because of a "kernal" error. If anyone can help, that would be awesome.

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 bougnt my S5 a month ago and I am having two major issues. The screen is very slow to respond. When the screen is dark and I press the home button, it doesn't come on. I have to press the button anywhere from 4-10 times and then it usually flashes on

I bougnt my S5 a month ago and I am having two major issues. The screen is very slow to respond. When the screen is dark and I press the home button, it doesn't come on. I have to press the button anywhere from 4-10 times and then it usually flashes on and back off. It is very, very frustrating. The other issue is that the battery drains very quickly. I have called Verizon numerous times regarding these issues. They tell me to do different things that never help. We eventually did a factory reset and it still has the same issues. Help! It is a brand new phone and unfortunately I am in a new two year contract. Ugh. Is there anyone out there who can help me?

I have done that several times. In fact, every time I call Verizon with my phone problems, they have me do the same things repeatedly. I keep telling them I have already done them but they insist they are SURE it will work this time. It never does. After doing the factory reset and it still not working correctly, they act like they are confused, almost like I am lying. I did what you suggested above on the slim chance it would work this time but it did not. I bought two S5's that day and the other one works perfectly fine. I know I got a bad phone. Verizon just does not listen. It is a bad phone. I just want a new phone that works properly. Is that too much to ask? I bought a new phone that has been bad from day one. Why oh why do I have to spend hours of my time on the phone, in the store, on the computer, trying to rectify this? It shouldn't be this difficult! Help please!!!

When using quicktime screen recorder, the recording changes colors

Please help me out!! So I've had my macbook air for a while now and I've used the quicktime screen recorder multipul times, but latley something changed. When I go to record my screen everything works fine, and once its finished and I've saved it it's still normal. But once I go to import it into imovie the entire recording turns red, I can still see the recording but everything is just red! Everywhere else the recording looks fine, but its only when I try to put it into imovie that it changes colors. Its never done this before and all of my past screen recordings work fine.
Does anyone know what I can do to fix it?
Any advice would be greatly appreciated!
Thank you

Hello meaganmarie,
I am assuming you have quicktime up to date (10.3)
When recording a game window,
- select quicktime
- go to file > New Movie Recording
- select your game window like a rectangular marquee selection (drag and make a rectangle filling only your game window
- stop when done and save
This way the endtire screen (including youe desktop) won't be seen, just your selected game window.
Regards,
Asevenc
