Slow loading Finder in Mavericks?

I bought the brand new Macbook Pro Retina that came with Mavericks plus I upgraded my old Macbook Pro Retina to Mavericks before my new one came. On both computers I am noticing a few different things that are rather annoying.
When attaching documents to emails, etc... it is taking my finder forever to load the contents of the directory I am trying to access. It is doing this on both computers, so I am assuming this is something to do with Mavericks and not the new computer. It is rather frustrating because for my job, I am contstantly attaching documents to emails every day, but having to wait a good minute or two for a directory to load to find what I am looking for to attach is getting rather annoying.
Even my stickie notes load slow now when opening them in Mavericks and it has never done that before. They kind of appear laggy when loading. Usually they just popped right up.
Is anybody else experiencing this problem? Any suggestions for a fix? I really enjoy Mavericks but it seems to be messing with the overall performance of some things.

This problem really negates any benefit that Mavericks may offer simply in the reduced productivity this slowness creates. I really struggled with it and was seriously contemplating reverting to the previous version of Mac OS X Mountain Lion. However, on reflection, I identified one of the features of Mavericks that could be responsible. App Nap. As I understand it, App Nap is designed to conserve energy and automatically slows down applications that are loaded but not currently active. If this is the case and it is applied to the Finder, then this could be the cause of our frustrations. On most Apps. in Maverick, using Get Info will present amongst other options, an opportunity to disable App Nap for the specific application. However, this option is not available for the Finder app. (/System/Library/CoreServices/Finder/Contents/MacOS/Finder).
I checked with Activity Monitor and discovered that the Finder process did get App Napped if unused so how to disable the App Napping? Happily, after some Googling, I came across these folks who had the answer:
http://www.tekrevue.com/tip/disable-app-nap-os-x-mavericks/
So I opened terminal and issued the following command:
sudo defaults write com.apple.Finder NSAppSleepDisabled -bool YES
Hey Presto, finder appears to be restored to its normal operating speed.
I suspect that to reverse this step, the above command should be issued with the argument NO.
If you try this, you do so at your own risk but I wanted to share it because of the frustrating impact it is having to so many folks.
Good Luck and please let me know if it works for you.

Firefox very slow loading most pages, sometimes error message :"can't find server for......." ....."

Firefox is very slow loading pages, some pages never load, sometimes error message stating "cannot connect to server" Router is not an issue I don't think as other computer connected to it has no problems. Used Malwarebytes to clean up problems, only 5 found. Internet Explorer does not have the same problems.

The default of the pref network.http.max-connections has been increased from 30 to 256 in Firefox 6+ versions.
Try to decrease the value of the pref <b>network.http.max-connections</b> from 256 to 30 as used in Firefox 3 versions.

Mac mini 2010 very slow after update to Mavericks

My mac mini 2010 (2.4 Ghz, 8GB ram) is running really very slow after updating to Mavericks.
Clearly OneDrive is a pain... but had it running on ML as well, and though it is a memory and CPU hog, it never really slowed down the system.

IMac - Slow load and wifi problems

I have lion installed on my macbook pro and on my iMac. My macbook pro works GREAT...no problems. My iMac - I am ready to toss out a window. Here are the problems:
INCREDIBLY slow boot up time - 5-10 minutes from off - 5-8 minutes from sleep
The hard drive is constantly working. I can have nothing open and it sounds like the hard drive is constantly spinning
Half the time my wifi hardware is not found on boot up and I have to reboot with slow load times - sometimes taking 20 minutes before I can get logged in to a 'working' computer
A lot of my programs have become slow. Safari can be slow responsive but others that are not apple that have done 'lion updates'
I have my activity monitor running and nothing seems to be hogging resources. My iMac specs are:
2.8 intel core i5
12 gb ram
2 TB hard drive with about 1tb free
I ran the lion update that came out and it did not seem to do much for me.
Anyone have a solution? Anyone tried a clean format and did this work? Lion works great on my laptop and I just need it to work on my main computer as well.
Reba

i think part of the boot up time issue is the amount of windows you happen to have open when you put it to sleep
other is lion upgrade slows it down due to this auto save function
my wifi is also spotty and acts like it can't find itself at times
and this is a brand new imac

My 6-year-old iMac is painfully slow after I installed Mavericks, despite increasing ram to 4 GB. Any help out there?.

My 6 year old iMac is painfully slow after I installed Mavericks, despite upgrading to 4 GB of Ram. Everything stops and I see the spinning beachball way too frequently. Any suggestions or solutions?

Launch the Console 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 Console in the icon grid.
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Click the Clear Display icon in the toolbar. Then try the action that you're having trouble with again. Select any messages that appear in the Console window. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message (command-V).
When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some private information, such as your name, may appear in the log. Anonymize before posting.

My Mac has gone really slow since upgrading to Mavericks. Any suggestions as to how to speed things up again?

My Mac has gone really slow since upgrading to Mavericks. Any suggestions as to how to speed things up again?

First, back up all data immediately unless you already have a current backup. If you can't back up, stop here. Do not take any of the steps below.
Step 1
This diagnostic procedure will query the log for messages that may indicate a system issue. It changes nothing, and therefore will not, in itself, solve your problem.
If you have more than one user account, these instructions must be carried out as an administrator.
Triple-click anywhere in the line below on this page to select it:
syslog -k Sender kernel -k Message CReq 'GPU |hfs: Ru|I/O e|find tok|n Cause: -|NVDA\(|pagin|timed? ?o' | tail | awk '/:/{$4=""; print}' | open -ef
Copy the selected text to the Clipboard by pressing the key combination command-C.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V). I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key.
The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear.
A TextEdit window will open with the output of the command. Normally the command will produce no output, and the window will be empty. If the TextEdit window (not the Terminal window) has anything in it, stop here and post it — the text, please, not a screenshot. The title of the TextEdit window doesn't matter, and you don't need to post that.
Step 2
There are a few other possible causes of generalized slow performance that you can rule out easily.
Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
Reset the System Management Controller.
Run Software Update. If there's a firmware update, install it.
If you're booting from an aftermarket SSD, see whether there's a firmware update for it.
If you have a portable computer, check the cycle count of the battery. It may be due for replacement.
If you have many image or video files on the Desktop with preview icons, move them to another folder.
If applicable, uncheck all boxes in the iCloud preference pane. See whether there's any change.
Check your keychains in Keychain Access for excessively duplicated items.
Boot into Recovery mode, launch Disk Utility, and run Repair Disk.
If you have a MacBook Pro with dual graphics, disable automatic graphics switching in the Energy Saverpreference pane for better performance at the cost of shorter battery life.
Step 3
When you notice the problem, launch the Activity Monitor 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 Activity Monitor in the icon grid.
Select the CPU tab of the Activity Monitor window.
Select All Processes from the View menu or the menu in the toolbar, if not already selected.
Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for User, System, and Idle at the bottom of the window.
Select the Memory tab. What value is shown in the bottom part of the window for Swap used?
Next, select the Disk tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in andWrites out.)
Step 4
If you have more than one user account, you must be logged in as an administrator to carry out this step.
Launch the Console application in the same way you launched Activity Monitor. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Select the 50 or so most recent entries in the log. Copy them to the Clipboard by pressing the key combinationcommand-C. Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.
When posting a log extract, be selective. Don't post more than is requested.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some personal information, such as your name, may appear in the log. Anonymize before posting. That should be easy to do if your extract is not too long.

Safari is extremely slow loading web pages, i have to latest software, no updating needed

Safari is really slow loading internet pages and uploading images. I have the latest software update. I just purchased this mac book pro within the last 3 months..just frustrating that it's already this slow so soon....Any suggestions? I called tech support and nothing they walked me through helped. He was going to reinstall everything but I wanted to wait and see if there was anything else I could possible do before considering I just got this notebook, I hate to reinstall everything. It seems like there should be a simpler solution...

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of this exercise is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login. Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including your login items.
Launch the application(s) and test. Same problem(s)?
After testing, reboot as usual (i.e., not in safe mode.)

Reader Slow Loading?

Hi,
Since getting Safari 5.0.1 with Reader, it seems Safari is much slower loading pages now.
I'm not certain that it is reader slowing page loading but going to the same sites in Firefox and other browsers the pages load much faster.
I'll open a page in Safari, say CNN, and it takes so much longer to load now and it looks like the page will not open until Reader has done it's job.
Any suggestions?
Thank you.

Hi,
Empty your Safari cache more often. From your Safari Menu Bar click Safari/Empty Cache.
Web pages include a small icon or 'favicon' which is visible in the address bar and next to bookmarks. *These icons take up disk space and slow Safari down.* It is possible to erase the icons from your computer and start fresh.
*To delete Safari's icon using the Finder, open your user folder, navigate to ~/Library/Safari/ and move this file "webpageIcons.db to the Trash.*

Safari 4 slower loading with RSS feeds

Don't know what happened in Safari 4 (4.0.2), but now it is much slower loading initially because of the way RSS feeds in the bookmarks bar are now being handled. I can not use the browser until all the RSS feeds have been checked. Even when clicking on an RSS item within a particular page such as CNN, the time to open that feed is significantly slower.
There has always been occasional problems with the bookmark bar for RSS feeds showing there are unread feeds, yet nothing shows unread beside the individual feeds. The problem now happens almost every day. The only solution is to choose the view all RSS feeds and find the unread items.
I am also noticing that web page loading is also much slower than it was in 3.x. Get tired of that spinning loading at the right of the address entry bar. The beach ball is more interesting because it is in color.
I have 18 Mbps broadband, so that isn't the problem, as all the slowdowns happened as soon as I started using Safari 4.
So much for snappier loading

I don't understand why you're using Safari for your RSS feeds; it's not an ideal solution compared to a dedicated RSS reader like Vienna, NetNewsWire, or Newsfire; I'd use one of those and turn off RSS feeds in Safari's preferences pane.
But Safari 4 is faster than Safari 3; it isn't for you because of a variety of factors, so let's change them and see if we can't speed things up. Here's what you can do:
Try changing your Network settings to use OpenDNS
Go to ~/Library/Caches/com.apple.Safari and delete the contents of that folder, then use the Get Info panel to Lock the folder.
Go to ~/Library/Caches/Metadata/Safari and delete the contents of that folder, then use the Get Info panel to Lock the folder.
Go to ~/Library/Safari and delete these files:
Downloads.plist
History.plist
LastSession.plist
TopSites.plist (if you don't want to use Top Sites, Lock that file right after you restart.)
WebpageIcons.db
Restart Safari and see if your problem is solved.

My macbook pro is running really slow after upgrade to Mavericks

my macbook pro is running really slow after upgrading to Mavericks....any ideas?

OS X Mavericks: If your Mac runs slowly
The above link is not very useful, so if it doesn't help read on.
There are many potential reasons that a Mac may be running slower than expected, but more information is required to begin troubleshooting, much more.
Back up your documents and everything else important to you before proceeding. It is premature to conclude your hard disk is failing, but the symptoms you describe may presage an impending disk failure, and you should have backups anyway.
To help determine the possible causes of this behaviour read the following. None of what follows is intended to fix anything, but it will provide the additional information required to advance troubleshooting:
Boot OS X Recovery by holding ⌘ and r (two fingers) while you start your Mac. At the Mac OS X Utilities screen, select Disk Utility. Select your startup volume (usually named "Macintosh HD") and click the Repair Disk button. Describe any errors it reports in red.
When it finishes restart your Mac and test again for operation. If it's still not behaving as you expect it should, please post the results of EtreCheck in accordance with the following instructions:
Apple Support Communities contributor etresoft wrote a very useful app to quickly gather certain system information that may help point to a cause of this problem. Go to his website, download and run EtreCheck:
http://www.etresoft.com/etrecheck
Etrecheck will be in your Downloads folder. Open it from there. You may see the following dialog box:
Click Open - etresoft contributes to this forum frequently and can be considered a trustworthy developer.
It will take a moment to run as it collects its data.
Copy and paste its output in a reply.
Do not be concerned about anything that says "Problem" or “failed” or anything else that may appear in red.
EtreCheck was designed to remove any personal information (such as your computer's name and serial numbers) but if you see anything that looks like an email address or any other personal information that should not be divulged to others, please delete or obscure that information when you post the reply.
When you are finished with EtreCheck, quit the program. It occupies very little space, and you can keep it or drag it to the Trash as you wish.
After completing the above please determine if the problems also occur in "Safe Mode":
Safe Mode or "Safe Boot" is a troubleshooting mode that bypasses all third party system extensions and loads only required system components. Read about it: Starting up in Safe Mode
You must disable FileVault before you can start your Mac in Safe Mode.
Starting your Mac in Safe Mode will take longer than usual, graphics will not render smoothly, audio is disabled on some Macs, and some programs (iTunes for example) may not work at all.
Merely starting your Mac in Safe Mode is not intended to resolve the problem, it's to observe its performance without certain additional components.
To end Safe Mode restart your Mac normally. Shutdown will take longer as well.
System performance problems for reasons that cannot be isolated to any other cause justify an SMC reset. Be sure to read the procedure carefully and follow all the steps exactly as written, even if they seem inapplicable or trivial.

MacBook slow wakeup, black screen, Mavericks, took to Genius bar, worked OK for about a week and now the same.

MacBook slow wakeup, black screen, Mavericks, took to Genius bar, worked OK for about a week and now the same.
Screen actually seems a very dark navy blue almost black. sometimes can see cursor in white
Only happens sometimes

If you can somehow document any processes you've put the MacBook
through, which can cause it to repeat the symptoms you've seen, be
sure to write down the sequence of events if your action and resulting
issues can be make re-occur. Then you'd have a fair chance at some
one looking deeper to find the real cause of this problem. {If you have
a digital camera handy, you can take a picture of the screen if it should
display some curious content other than a black screen, such as that
seen in a kernel panic or other message. Otherwise, a working Mac
can take its own screenshot.}
The computer should be returned to the Apple Store genius bar for
further evaluation & more in-depth diagnostic tests of long duration.
Sometimes a test may not run any of the additional software, together
or separately, that you may be accustomed to using. Perhaps the basic
OS X and a few applications work just fine.
If the issue is due to a conflict in software and not a hardware failure,
the cause may be harder to discover. If you have a complete backup
of the system and your files on an external drive, that may help if you
need to reinstall it. However if there is a problem in that software set
a new installation without conflicting software may be required in order
to troubleshoot the machine.
How old is the computer, how much RAM installed, how large a hard
disk drive and what is the remaining unused capacity of that drive?
(The HDD capacity will show 'other' so that may be unsubstantiated.)
Are there any indications in Activity Monitor, or in the system log files
from Console, to show crash logs or other effects from the Time/Date
of these slow wakeup and black-screen intervals? There may be.
Some of the system report may be helpful to those who know how to
read the resulting mass of files. Perhaps one of the more advanced
users who occasionally reply here will see your thread and offer a
method of accessing the OS X via Terminal or single user mode,
for troubleshooting purposes. Mine is an older OS X with less fuss.
Good luck & happy computing!

HT201364 how do I remove items from startup disk to load OS X Mavericks?

I'm trying to load OS X Mavericks and I'm getting a message to remove items from startup disk. Can anyone tell me how to do that??

For information about the Other category in the Storage display, see this support article. If the Storage display seems to be inaccurate, try rebuilding the Spotlight index.
Empty the Trash if you haven't already done so. If you use iPhoto, empty its internal Trash first:
iPhoto ▹ Empty Trash
Do the same in other applications, such as Aperture, that have an internal Trash feature. Then reboot. That will temporarily free up some space.
According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation. You also need enough space left over to allow for growth of the data. There is little or no performance advantage to having more available space than the minimum Apple recommends. Available storage space that you'll never use is wasted space.
When Time Machine backs up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of recently deleted files. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown as Backups. The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself. If you followed bad advice to disable local snapshots by running a shell command, you may have ended up with a lot of data in the Other category. Reboot and it should go away.
See this support article for some simple ways to free up storage space.
You can more effectively use a tool such as OmniDiskSweeper (ODS) or GrandPerspective (GP) to explore the volume and find out what's taking up the space. You can also delete files with it, but don't do that unless you're sure that you know what you're deleting and that all data is safely backed up. That means you have multiple backups, not just one. Note that ODS only works with OS X 10.8 or later. If you're running an older OS version, use GP.
Deleting files inside an iPhoto or Aperture library will corrupt the library. Any changes to a photo library must be made from within the application that created it. The same goes for Mail files.
Proceed further only if the problem isn't solved by the above steps.
ODS or GP can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To see everything, you have to run it as root.
Back up all data now.
If you have more than one user account, make sure you're logged in as an administrator. The administrator account is the one that was created automatically when you first set up the computer.
Install the app you downloaded in the Applications folder as usual. Quit it if it's running.
Triple-click anywhere in the corresponding line of text below on this page to select it, then copy the selected text to the Clipboard by pressing the key combination command-C:
sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
sudo /Applications/GrandPerspective.app/Contents/MacOS/GrandPerspective
Launch the built-in 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 icon grid.
Paste into the Terminal window (command-V). You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning to be careful. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The application window will open, eventually showing all files in all folders, sorted by size. It may take a few minutes for the app to finish scanning.
I don't recommend that you make a habit of doing this. Don't delete anything as root. If something needs to be deleted, make sure you know what it is and how it got there, and then delete it by other, safer, means. When in doubt, leave it alone or ask for guidance.
When you're done with the app, quit it and also quit Terminal.
