ICal in Lion is extremely slow.

It takes one or two minutes to respond to any keyboard entries. All functions in iCal are locked unti then.
Is this an known issue and is there a fix for this? I have replaced my iCal dock icon with the original application. I also publish my calender privately so I can sync it with my Macbook Air.

I'm having this same issue. When I click new event it takes 20 seconds for iCal to unfreeze so I can edit the times, etc for that event. Sometimes even the page flip locks up. It's really annoying - I had no issues with the old iCal but I don't like this new one at all. I'd look for something else, but there'd be no way to sync it to my iPhone which is what I really depend on. Hmm....adding events to my iPhone and then syncing would actually be faster than using iCal on my Mac now.
Apple, please release an update addressing this!

Lion graphics extremely slow with Radeon HD 2600 Pro 256MB

Made a clean install with Lion and it now turns out that the graphics (Radeon HD 2600 Pro 256MB) on my Core 2 Duo iMac are way to slow (or insufficient VRAM) for the Lion UI.
Especially fullscreen apps animations and opening Launchpad folders are extremely choppy. Not much fun the way it is.
I mean come on, a mac, which can play WoW pretty well should be able to push 2D Graphics around, right?
When booting up the UI is fast, but after letting the iMac on for a while or waking it from sleep the graphics are choppy again.
Anyone else having this problem?
Regards,
Kersten

Macbook Pro late 2010 build Lion OS extremely slow

I have a Macbook Pro late 2010, purchased with OS Snow Leopard. I then upgraded to Lion with the result that all native and added applications open, perform, and close extremely slowly. Mail is the worst, with opening sometimes taking 20 seconds, closing longer. I would appreciate any ideas for a remedy, short of removing Lion and and reinstalling Snow Leopard. Thanks

Lion is extremely slow instead of Snow Leopard

Before of all, I'm sorry for my bad english, and I hope you'll understand me.
I have a MacBook Pro early 2011, 15" 2,3 Ghz Intel Core i7 4Gb Ram DDR3 with Snow Leopard integrated.
I Upgraded to OS X Lion but my MacBook Pro was very slow, so I done all those things:
Complete format (Osx extended). OS X Lion installation without recover from backup. Reset PRAM.
Nothing to do, instead of Snow Leopard my mac is terribly SLOW, on all application, all program, to see a mail, and on startup we don't have to talk: is slow, and at the end the screen show a blue screen for a second or two, and then it boot normal.
I tried to format again, but Snow Leopard was so faster than Lion. What I supposed to do? I've lost my money buying a bad operative system that transform my MacBook Pro super expansive in a low cost MacBook of the past years?

I'd do two things:
1) Use Activity Monitor to investigate whether there's something using excess CPU time.
2) Use the Console utility to see if there is something writing a large number of error messages.

Aperture 3 and Lion work extremely slow.

Its like my computer was from the 90's. Even with a simple task as using a brush to remove dust will take very very long to process. Any clues?

IMac CPU3.06 GHz Intel Core 2 Duo, 8GB, Extremely slow and repeatedly "out of Memory" since migration from Mountain Lion to Mavericks

Dear Apple Support Community.
As mentioned by a number of users reporting the same problem, my 2009 iMac CPU3.06 GHz Intel Core 2 Duo, 8GB RAM, has become extremely slow and repeatedly "out of Memory" since it was migrated from Mountain Lion to Mavericks (OS 10.9 then OS 10.9.1).
I have already run CleanMyMac, deleted 5GB of useless stuffs, which did not translate into any improvement. Following the advices collected in other Apple Support Community threads, I have applied EtreCheck the outcome of which is provided below.
For information, I have also upgraded my 2011 MacBook CPU2.3 GHz Core i7, 8GB which became only a bit slower than before, sometimes freezing which it almost never did before. However, I am used to the fact that Mac get usually slower and more prompt fo freeze after upgrading to a more recent OS.
Both my 2009 iMac and my 2011 MacBook have F-Secure installed. So the problem with the 2009 IMac is unlikly to be due to the presence of F-Secure. Interestingly, the few abnormalities found by Etrecheck were exacly identical before I ran CleanMyMac. There are two more findings (mentioned below) since I ran CleanMyMac on the 2009 iMac, which again didn't improve the problem.
So please find below the details of the EtreCheck experience and some additional measurements made with iStat while running EtreCheck:

Please find now some additional measurements collected with iStat while running EtreCheck:
Practically:
The iMac can work slowly with only one software e.g. either Mail or Safari or Firefox, but still the below "out of Memory" message occurs about every 3 minutes.
Aperture has becomre to slow to be useable
If trying to write a mail (with Mail) while Safari or Firefox is open, then the "out of Memory" message occurs about every 20 seconds so I need to check on "Resume" several times per minute.
Conclusions
From the above, unless anyone in the Apple Support Community proves to be able to identify a specific problem leading to a way to find a cure, I tend to conclude that Mavericks is not suitable for computers operating with a Core 2 Duo CPU even with a 8GB of RAM.
Unless I missed something, I did not see any warning from Apple Computer Inc. informing their customers they should refrain from upgrading Core 2 Duo Computers.
The only solution I see so far is to downgrade from Mavericks to Mountain Lion. And the Apple Support Community would confirm that it is the only solution, I would appreciate to get your guidance on how to proceed.
Intended action plan
Migrate the above 2009 iMac to a 2014 Mac Mini Server operating on Mavericks to ensure that no data may be lost while downgrading to Montain Lion.
Provided the above downgrading operation is successful, assign this 2009 iMac to partial retirement e.g. Mail, Skype, iTunes and DVD player.
In advance, I would like to thank the Apple Community for helping me either i) finding a cure to the problem, ii) or confirming that Mavericks cannot operate properly on Core 2 Duo computers, iii) and in such a case, guiding me on how to downgrade to Mountain Lion.
Yours sincerely
Core

... what anti-virus would you recommend using?
Use what is already included with OS X. It already includes everything it needs to protect itself from viruses and malware. Keep it that way with software updates from Apple.
A much better question is "how should I protect my Mac":
Never install any product that claims to "speed up", "clean up", "optimize", or "accelerate" your Mac. Without exception, they will do the opposite.
Never install pirated or "cracked" software, software obtained from dubious websites, or other questionable sources. Illegally obtained software is almost certain to contain malware.
Don’t supply your password in response to a popup window requesting it, unless you know what it is and the reason your credentials are required.
Don’t open email attachments from email addresses that you do not recognize, or click links contained in an email:
Most of these are scams that direct you to fraudulent sites that attempt to convince you to disclose personal information.
Such "phishing" attempts are the 21st century equivalent of a social exploit that has existed since the dawn of civilization. Don’t fall for it.
Apple will never ask you to reveal personal information in an email. If you receive an unexpected email from Apple saying your account will be closed unless you take immediate action, just ignore it. If your iTunes or App Store account becomes disabled for valid reasons, you will know when you try to buy something or log in to this support site, and are unable to.
Don’t install browser extensions unless you understand their purpose. Go to the Safari menu > Preferences > Extensions. If you see any extensions that you do not recognize or understand, simply click the Uninstall button and they will be gone.
Don’t install Java unless you are certain that you need it:
Java, a non-Apple product, is a potential vector for malware. If you are required to use Java, be mindful of that possibility.
Disable Java in Safari > Preferences > Security.
Despite its name JavaScript is unrelated to Java. No malware can infect your Mac through JavaScript. It’s OK to leave it enabled.
Block browser popups: Safari menu > Preferences > Security > and check "Block popup windows":
Popup windows are useful and required for some websites, but popups have devolved to become a common means to deliver targeted advertising that you probably do not want.
Popups themselves cannot infect your Mac, but many contain resource-hungry code that will slow down Internet browsing.
If you ever see a popup indicating it detected registry errors, that your Mac is infected with some ick, or that you won some prize, it is 100% fraudulent. Ignore it.
Ignore hyperventilating popular media outlets that thrive by promoting fear and discord with entertainment products arrogantly presented as "news". Learn what real threats actually exist and how to arm yourself against them:
The most serious threat to your data security is phishing. To date, most of these attempts have been pathetic and are easily recognized, but that is likely to change in the future as criminals become more clever.
OS X viruses do not exist, but intentionally malicious or poorly written code, created by either nefarious or inept individuals, is nothing new.
Never install something without first knowing what it is, what it does, how it works, and how to get rid of it when you don’t want it any more.
If you elect to use "anti-virus" software, familiarize yourself with its limitations and potential to cause adverse effects, and apply the principle immediately preceding this one.
Most such utilities will only slow down and destabilize your Mac while they look for viruses that do not exist, conveying no benefit whatsoever - other than to make you "feel good" about security, when you should actually be exercising sound judgment, derived from accurate knowledge, based on verifiable facts.
Do install updates from Apple as they become available. No one knows more about Macs and how to protect them than the company that builds them.
Summary: Use common sense and caution when you use your Mac, just like you would in any social context. There is no product, utility, or magic talisman that can protect you from all the evils of mankind.

Ever since my upgrade to lion 10.7.3, and iCloud, my macbook is running extremely slow. What can I do? It doesn't seem like my contacts are pushing through to the computer from iPhone.

Ever since my upgrade to lion 10.7.3, and iCloud, my macbook is running extremely slow. What can I do? It doesn't seem like my contacts are pushing through to the computer from iPhone.

Then your basic issues are: too little RAM, incompatible software, dysfunctional installation.
Add more RAM or kill as many programs that you use until the computer is running normally.
See App Compatibility Table - RoaringApps. Upgrade any old software.

After encrypting with filevault 2 on mountain lion, safari is extremely slow

after encrypting with filevault2 on mountain lion, safari is running extremely slow.
it's taking more than 45 seconds (sometimes a full minute) to load pages.
my internet speeds are 35 mbps download and 6.35 mpbs upload, so it's not my internet connection.
i have deleted the cache files and the system preferences.
i'm finding that chrome is faster, but i'm seeing slowness there too.
in encrypted using filevault 2.0 yesterday, all software is up to date.
can anyone please help me with this? i don't want to have to turn off filevault.
thanks!

Problems such as yours are sometimes caused by files that should belong to you but are locked or have a wrong owner. This procedure will check for such files. It makes no changes and therefore will not, in itself, solve your problem.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the page that opens.
Triple-click anywhere in the line below to select it, then drag or copy it — do not type — into the Terminal window:
find . $TMPDIR.. $ -flags +sappnd,schg,uappnd,uchg -o ! -user $UID $ -ls
Press return. The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear.

Safari 6 running extremely slow after getting Mountain Lion

So after getting OS X Mountain Lion and Safari 6, my safari has been running extremely slow. I've seen that a lot of people are having trouble with it crashing or stopping which I have not experienced. So far, I've tried: emptying the cache, disabling plug ins, turned off extensions, and reset safari. All of these have helped but it is still running pretty slow.
Does anyone have any other suggestions?

If you have anti virus software installed, disable that then try Safari.
If you don't have a/v software installed, try Safari in another user account. If it's slow there, that's an indication the startup disk may need repairing.
If that is the case, that requires > Mountain Lion Recovery

Numbers 09 (Rel. 2.1(436)) extremely slow under Lion

I just gave Numbers a try with a relatively low complex mortgage calculation - 13 columns, 200 rows - simple formulas (if ... then ... else, difference in dates, simple multiplications).
Numbers is extremely slow - whenever something is changed in the tables, Activity Monitor shows 100% CPU usage and the SBOD appears - it's nearly not possible to work. Restart of my MacBook Pro or Numbers allone has not made anything better. Has anybody made the same observations, i submitted feedback to Apple, but i have the feeling, that nobody is reading it (3 years ago i submitted the wish for goal seek for Numbers or some sort of Automator support)
The dilemma is:
Many of my coworkers now have iPad and iPhone and could use Numbers (i know there are some Excel Simulations for iPad and iPhone around, but these are not so nice to use) - therefore i want to provide the previos Excel Sheets as Numbers documents - but with this performance it's impossible to use Numbers.

"200 rows of formulas in a Numbers document might be considered to be large ..." - that's complete nonsense - in the beginning of my "Apple History" i had a Mac IIsi, on this machine there was a spreadsheet software running, it's name was Ragtime - i did exact the same calculations which i now want to redo with Numbers - the IIsi with 8 MB of RAM was crunching trough these calculations a lot faster than my Macbook Pro - and there were not only 200 rows to calculate - (to be exact it were 300 + (4 x 25) rows - calculation 300 months + 4 quarters per year).
Apple builds very nice hardware (most of the time), Apple designs very nice software (also most of the time) - but sometimes Apple Software is truly unusable if one decides just to get one step ahead the absolute-zero-level-hobby-user.
Of course i know the phrase "horses for courses" and everybody will scratch his head "why does this guy absolutely want to use Numbers for this task and not the old Excel?" - i can tell you that: Because Excel has very bad layout options - in Numbers i can produce very nice layouts, free movable tables, integrated pages which sum up more sub-tables ... - yes, thats also possible with Word an Excel but not in this intuitive way Apple has come up.
BUT - since Numbers is (and keeps) so dramatically slow it's barely unusable - it makes me sad, that i will never see Numbers being used in a business environment.
PS: please excuse my rough English, i'm from Austria.

OS Lion Extremely Slow

Hi. I'm trying to figure out why there are thousands of users complaining about OS Lion being incredibly slow, which it is for me on my MacBookPro as well, and Apple is not responding. Does anyone have any solutions to this obvious problem? Thanks!

My iMac is running extremely slow after upgrading to mountain lion

Ever since upgrading my OS, my computer is running extremely slow. Any tips to improve performance?

How much RAM is your system running? Do a Disk Repair and see if that resolves any issues.

Processing speed of my MacBook is extremely slow when opening applications, whether Mail, Safari or MSOffice

Problem description:
The processing speed of any function is extremely slow - such as opening Mail, Safari, clicking on a page within Safari, switching to MS Word, adding a window in Safari, loading a page from Safari. I get the spinning wheel most of the time before the action is completed. All other Macs which are newer in my home WiFi network operate just fine. I have done a top level (novice) check for malware, and haven’t found anything. Any help you can suggest would be truly appreciated! Thank you!

Before you do anything do you have a current backup? If not make one.
I don't see any of the usual software suspects associated with slow downs. You don't need the Seagate software, you should uninstall that.
Reset the SMC Intel-based Macs: Resetting the System Management Controller (SMC) - Apple Support and PRAM How to Reset NVRAM on your Mac - Apple Support
You only have 2GB of ram and could upgrade to 8GB, but Snow Leopard should run ok in 2GB.....not great but ok.
Start up in Safe Mode OS X: What is Safe Boot, Safe Mode? - Apple Support be paitient as it will take awhile to start as it checks and tries to repair any problems with the file system. Once it's completely started up you can restart normally.
Insert your Snow Leopard disc and restart while holding the C key. Run Disk Utility to repair the hard drive and permissions. While in Disk Utility check the SMART status of the hard drive, anything other than Verified indicates a problem with the hard drive.
Again, you only have 2GB of ram.....try restarting your Macbook every day.....it's been running for almost a week now.

ICal in Lion is extremely slow.
