VERY SLOW and HOT - Mountain Lion - CalendarAgent

After some days of ML installation, my iMac become extreme slow. It´s impossible to work with.
The Activity Monitor show a very high usage in CPU and RAM used by CalendarAgent. I´ve tried to delete accounts and reinstall them - without success.
After closing the process within the Activity Monitor App, it re-appears somewhen automatically.
Additional my iMac becomes very hot in comparison to Snow Leopard.
Currently, it´s impossible to work with my iMac. I just know this behavior from Windows PC´s after 2 years of usage. And this was the reason to switch to Mac.
I appreciate proposals to solve this problem and definitve a fix from Apple ASAP!!!

I advise everybody to put their hands on their iMacs. My iMac gets so hot doing only easy work like texting I can almost not touch it. In addition the fans are not running full speed, as they should with this hot temperatures. I can barely hear them, this is definitely a dangerous bug in Montain Lion.

My macbook pro is very slow after installing mountain lion

my macbook pro is very slow after installing mountain lion? Is anyone else having this issue?

If you don't use an SSD and bump your RAM up to 8 Gb's you may experience slow speeds, but I noticed slow speeds with your general configuration in SL.
one thing you should consider right now is, Spotlight is Reindexing your hard drive, that takes time and resources, (resources which you don't necessarily have to spare).
If you continue feeling like your performance is slow, you have a few options with this computer (I have the same one).
the express card slot can house a wintec SSD drive. That little door on the side of your machine is pure gold for a really quick solution for speeding up your machine. I have one in mine right now i'm using as a scratch disk for CS6 but I used to boot from it, and the speed boost was out of this world.
You could take out the internal HDD and put in a new SSD (I have a Vertex 4 from OCZ) it is completely over kill but my experience is pretty fast and I keep up with the later MBP models colleagues have.
There are some other options for you like taking out the optical drive (however I don't know if I'm supposed to talk about that here). Google Data Doubler.
You need to also set it to always use the 9600 chipset, this will increase performance a lot too. to do this go to system preferences>energy saver>Better Performance. This switches the video card to the better one and makes a world of difference.
Lastly, your RAM. after an EFI Firmware update, our computer support up to 8GBs of RAM. Do it!

My wifi is very slow after installing mountain lion on my Mac book pro

My wifi is very very slow after installing mountain lion on my MacBook pro.
What can I do?

Ha ha, I misread that as "My wife is very slow after installing mountain lion on my Mac book pro"
BTW on my MBPro (late 2009 with max RAM) Mountain Lion runs very well with no slowing down.

Why is my MacBook Pro very slow after installing Mountain Lion 10.8.5. - Solutions?

Hello, hello
After waiting quite a while - I paid the relatively small amount, and got myselves a new OS.
But I am very disappointed of the speed - I see that this also was a problem with OS Lion?
Please assist me. Perhaps others have this problem as well?
Some info:
- 2,66 GHz Intel Core i7 processor
- 4 GB 1067 MHz DDR3
Also
- Sometimes I run the Parallels Desktop 6 and 9 software, does this affect specs of the new OS?
Hope to hear from you guys.
Sincerely,
Harald

With only 4GB of RAM, how much do you have devoted to the virtual machine running under Parallels? Even if it's a small amount, it's going to make page outs and swaps used very high. From my perspective, 8GB of RAM is the 'sweet spot' for running Mountain Lion.
I'm assuming that you've a 15" mid-2010 MacBook Pro? If so, you can speed things up by installing the maximum 8GB of RAM. Go RAM shopping at Crucial or OWC.
Other than upgrading your RAM, the only thing that you can do to speed up your machine is to install a SSD. You can also check the SSDs at Crucial and OWC and decide if one is right for you.

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.

After upgrading my iPad 2 is slow and hot, is the a solution?

My Ipad 2 is very slow, and hot never have this....is their a solution?

I upgraded my iPad 2 to iOS 6 as soon as it was available, and, since the upgrade, I've noticed a significant increase in the rate of battery drain. I charged my iPad overnight last night, and it was 100% charged when I started using it this morning. I made sure that Location Service and Bluetooth radio were off. I used it to web browse, compose an email, and read a PDF document. I used it for about four hours continuously, and the battery was down to 50%. That is draining the battery much faster than before the OS upgrade. Unfortunately, I did not backup the iPad before upgrading. I did the upgrade over WiFi. The PC on which I have iTunes died, and I don't have a replacement machine on which to back it up yet. If I had a good backup, I'd restore it and forget about this upgrade until there's a fix for the battery problem, if there ever is one. I'm glad I waited to upgrade my iPhone 4S. I rely on it more and don't want to deal with rapid battery drain on it. I upgraded to the iPhone 4S from the 3GS. My 3GS was rendered almost useless when I upgraded to iOS 5 when it came out and caused rapid battery drain on the phone, which Apple never fixed. Also the performance of the 3GS with iOS5 was so slow I could hardly stand using it for anything. That experience led to my decision to wait on upgrading my 4S to iOS 6. It's unfortunate that such a great family of products is plagued with this battery drain problem, and with all their resources, Apple cannot or will not fix the problem. As far as I know, they have not even acknowledged a battery drain problem with iOS 6. To me, the battery drain problem is much worse than the problems with the mapping software that Apple is using to replace Google Maps in iOS 6. Rather than apologizing, I would like for Apple to acknowledge the battery drain problem and fix it.

Mountain lion download is very slow and in-between it hangs of and starts from beginning. Is there a solution i have already purchased it can i download a torrent and authorize it

Mountain lion download is very slow and in-between it hangs of and starts from beginning. Is there a solution I have already purchased it can I download a torrent and authorize it. Somebody pl. Help

Exactly. Some of us don't understand the situation in India. This is a country with sickest internet speeds. The internet segment is dominated by fraudulant companies. There is no consistency that is why most of the data transfer here is through Pen drives and torrent websites. We have never seen a good downlooad speed here. And on the top of inconsistency lies the Mac book Air without a built in RJ45 port.
If i have to do it in an internet cafe it will cost me more time and money than to purchase a Mac book air itself. Apple should start giving us software loaded flash drives at least at premium.

My macbook pro is running very slow and very very hot

hi everyone I have a 13 inch mid 2012 MacBook pro,
it is running very very slow and extremely hot, I downloaded a program called smc fan control and it is reading the internal temperature of my computer as 80 degrees Celsius. I was looking on the forums and saw that I should run an apple hardware test. which I have done and it is coming up with Error 4/MOT/4/40000002: EXHAUST-2003
what does this mean? is it something to do with my fan?
also there is a very strange clicking noise when I lift the mac up or if its on its side and sometimes it just randomly freezes, the computer does not respond and then it restarts.
what do I do?
please help!

" the fan didn't seem congested with dust, at least not enough to cause any malfunction."
The lint and crap builds up in the heat exchanger radiator. It's the grilled thing at the output of the fan.
https://www.ifixit.com/Guide/MacBook+Pro+13-Inch+Unibody+Mid+2012+Fan+Replacemen t/10367
Look at step 6. It's that grilled thing at the top of the fan. If you remove the fan that radiator is probably clogged with lint. Brush it all away and if possible blow out the fan with compressed air. Make sure the fan turns freely and doesn't feel stiff.

This isn't a MBP radiator but the problem will look like this.

HT1338 I need to update to Lion and then Mountain Lion, but I need a CD or other means to update as my internet is too slow and I have a GB limit. Is this possible?

I need to update to Lion and then Mountain Lion, but I need a CD or other means to update as my internet is too slow and I have a GB limit. Is this possible?

Thanks for your response. I was told, obviously misinformed, that you needed to dl Lion prior to Mountain Lion, so thanks for clarifying that. I cannot dl from the internet as it is too slow and I have limited GB per month. I know, at one point, you could purchase a jumpdrive with Lion for those of us who have this problem or no internet access. I will check into that via Apple or try to borrow internet service from a friend and move my computer there.
Thanks again.

After update to Lion Numbers became very slow and clumsy.

After update to Lion, Numbers works very slow and clumsy. Any solution to fix this problem?

Don't know about being "slow" - I've always felt it was slow. I could run Office XP (maybe 2000 - not sure) on an 133 mhz Pentium and it was faster than Numbers on my late 2008 Aluminum MB.
But I've had other issues under Lion with it. It seems whenever I first go to my spreadsheets after the computer has been asleep - even if it is some time after waking it up - and start to enter some numbers, I'll get a beep and see that what I tried to type didn't come out right and I have to do it again.
I was wondering if it was something to do with the auto-save versions maybe kicking in when I first start to enter info, but before I finish the first entry.

My mac has become very slow and crashes frequently after installing Lion

My mac has become very slow and crashes frequently after installing Lion. I have a 4 GB DDR3 ram and 2.4 GHz Processor. The Mac was running just fine on Snow Leopard. Has anyone else faced this issue?
Any suggestions on how to solve it?
Thank you
Kimberly M. Noronha

I refer you to the TM expert
http://web.me.com/pondini/Time_Machine/14.html
As a extra precaution I would copy the user file folders of Music, Documents, Pictures etc to another external drive and disconnect, just in case.
Always maintain TWO backups of your data at all times, since your messing with one, you need another until your back at two again.

My MacBook pro is running very slow and unresponsive.

My MacBook pro is running very slow and unresponsive. I have mid 2010 model running on lion. Past few days it looks very unresponsive. Tried to reinstall lion as clean copy. Still no luck. Any help on this is much appreciated !
My model has 4 gb ram.

Things That Can Keep Your Computer From Slowing Down
If your computer seems to be running slower here are some things you can do:
Boot into Safe Mode then repair your hard drive and permissions:
Repair the Hard Drive and Permissions Pre-Lion
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
Repair the Hard Drive - Lion
Boot from your Lion Recovery HD. When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
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.
Restart your computer normally and see if this has helped any. Next do some maintenance:
Suggestions for OS X Maintenance
For situations Disk Utility cannot handle the best third-party utility is Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible.
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger. These utilities have limited or no functionality with Snow Leopard or Lion and should not be installed.
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems. For more about malware see Macintosh Virus Guide.
I would also recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc.
For emergency repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. There is no confirmation that this version also works with Lion.
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand.
Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
Carbon Copy Cloner
Data Backup
Deja Vu
SuperDuper!
SyncTwoFolders
Synk Pro
Synk Standard
Tri-Backup
Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.
Additional suggestions will be found in Mac Maintenance Quick Assist.
Referenced software can be found at CNet Downloads or MacUpdate.
Additional Hints
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
Add more RAM. If your computer has less than 2 GBs of RAM and you are using OS X Leopard or later, then you can do with more RAM. Snow Leopard and Lion work much better with 4 GBs of RAM than their system minimums. The more concurrent applications you tend to use the more RAM you should have.
Always maintain at least 15 GBs or 10% of your hard drive's capacity as free space, whichever is greater. OS X is frequently accessing your hard drive, so providing adequate free space will keep things from slowing down.
Check for applications that may be hogging the CPU:
Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time, then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Often this problem occurs because of a corrupted cache or preferences file or an attempt to write to a corrupted log file.

Very slow external sata HD (lion)

Hi everybody!
It has been a while I am using a Netstor external HD (NR710C) 4x2TB WD Caviar black, RAID 10 (4TB total space, 2.71 Available, MacOS Extended Journaled).
It is conntected with the MacPro (MacPro 4,1 - early 2009) via a Sonnet Tempo SATA E2P pci card (drivers updated)
The OS installed is Mac OS X Lion 10.7.3 (11D50d) on a OCZ SSD 250GB
What happen is that randomly the access to the external RAID HD is very slow and while finder try to open subfolder the entire system freeze for a minute or so. Soemtimes the opened folders looks empty and I have to wait a minute or so to see the content.
When I used Snow Leopard (installed on a 1TB HD) the access was always fluid and fast.
What I've done to try to solve this issue is:
Unchecked the "Put the hard disk(s) to sleep when possible) in the Energy Saver panel.
Changed slot of the PCI card
Changed sata plug and cable
Performed all the check disk possible
It happens as well that the copy/move of big folder (up to 800GB) is not always as fas as it should be.
Also, working with Lightroom (cache is on the SSD hd) is really frustrating due the slow access to all the files.
I was used to work directly on the external sata HD but now seems like if I have to move everything back on an internal HD.
Is there any other check I can perform to address this issue?
So many thanks.
Luca

The case has an eSata port and cable.
I've run a speed test (Xbench) on a 2TB internal drive and the external RAID.
Here is the result. It seems the speed is good.. is it correct?

XSERVE 10.6.8 is running very slow, and Workgroup Manager is not responding. There is no more updates to download.

1. upgrade to lion, which should over write previous software and the reasons for it being slow.
No, you don't want to upgrade over a buggy system, Lion has issues of it's own that will only complicate matters, plus Lion is slower than Snow Leopard.
Learn all the pitfalls before you upgrade to Lion, like all your Rosetta/older programs will no longer work and more.
Leave Lion for a new hardware purchase is my advice, it's still got plenty of security and other issues.
For your performance, your likely better off replacing the hard drive with a 7,200 RPM model and maxing the RAM, download the free MacTracker to find out your specs, and OtherWorld Computing is good for videos, tools and parts.

2. Format the hard disc and reinstall snow leopard.
That will work, provided your data is off the machine first.
Now how do i reinstall snow leopard as it was an online purchased upgrade from leopard.
The 10.6 Snow Leopard disk that you upgraded 10.5 Leopard from actually has the full OS X 10.6 on it.
All you have to do is stick the disk in and hold the c key down while booting, use Disk Utility to erase the entire drive, quit and install 10.6.
Of course your not going to get the free iLife that came with the 10.5 grey disks, see if you can first install 10.5 with the same methods, then setup with the same user name as before, then upgrade to 10.6
I think Apple nulled booting off the 10.5 disks, but it won't hurt to try.
Another method would be to install 10.6 fresh by itself, then use the program called Pacifist to extract iLife from the 10.5 disks.
