Wifi Issues after updating to Mavericks

After updating to Mavericks, the wifi on my 2011 Macbook Air started to drop a few minutes after connection. I performed wireless diagnostics, and here are the logs generated by the program.
First is the monitoring log:
# --- Monitor Test Cases

Might be corrupted network preferences ...
Open the Finder. From the Finder menu bar click Go > Go to Folder
Type or copy paste the following:
/Library/Preferences/SystemConfiguration
Click Go then move all the files in the SystemConfiguration folder to the Trash.
Turn off the base station for about ten seconds then turn it back on.
See if that makes a difference.
Your Mac will generate a new SystemConfiguration folder for you.
See if that helps the Wi-Fi connection.

Preview app issue after update to Mavericks

Since I updated to OS Mavericks my preview app has not been functioning properly. When the app is open when viewing PDFs a window (accompanied by a progress bar) pops up quite frequently that says "Saving changes... '#' documents remaining", with the # sign representing any number of documets. Often, the number of documents "remaining to be saved" progressively increases from 1 to 8 or so, despite there being only one document open. While the app is doing these "auto saves" my computer is slowed down significantly and while these interuptions occur I am usually unable to do anything else.
I will also add that the size of the PDF files that I view are rather large, on average 70-80 MB, although I'm not sure if that is the reason for the issue because before I updated to Mavericks I didn't have this problem. And the problem does also seem to occur with smaller sized files as well.
My computer usage is usually minimal when this occurs, typically only Safari is open in the background. I was advised to reset my SMC, which I did, but the problem is still occurring. Any additional advice or solutions would be much appreciated. Thanks.

I have just experienced this exact same issue.
I have been adding text notes and highlighting to a PDF document that is saved on an external USB drive. When I left work yesterday I told preview to save the changes. I did notice the Saving Changes dialog appear and before I left it said 3 documents remainin, even though I only had one document open in preview. My USB drive was connected and mounted when I left work.
On my return in the morning I noticed that the Saving Changes dialog had not gone away. For some reason my USB drive was unmounted and I had the OS X message about ejecting drives before disconnecting them so I re-seated the USB cable and my drives remounted. Immeditately after doing this the Saving Changes dialog in preview started counting up from 3 to 8. It is now sitting at 8 and the progress bar is empty.
I had a look in Console and did not notice anything strange. I also grabbed a sample of the Preview process using Activity Monitor but I have little clue what to look for. Whilst I was running console and activity monitor and such I did notice that the Saving Changes dialog has climbed further to 14 now and it appears to increase whenever I bring preview into focus or move away from preview. I appear to have no option but to force quit preview so that I may continue working.
My PDF document is 26.5M.
I have a Macbook Air (13-inch, Mid 2011), 1.7GHz i5 with 4GB RAM running OSX Mavericks 10.9.1.

WiFi issues since updating to Mavericks

Having recently bought my MacBook Air, it came with Mountain Lion as the preinstalled OS. I decided to update to Mavericks last night, and installed from the Mac App Store. The install was obviously simple, but it has thrown up an issue that I did not anticipate.
I am able to access WiFi at all times, but only an active internet connection whilst in the Recovery mode. Whilst running Mountain Lion I had no issues, and my router settings have not changed in this time. I have done one reinstall of Mavericks whilst in Recovery mode to see if that would fix the issue, but still no joy.
Not exactly the experience I had hoped for, and at the moment I am almost ready to throw in the towel. I know this issue is not with my router or network config. It is the MacBook Air, AirPort is an extremely poor way to connect to a wireless network as far as I am concerned.
Any help is much appreciated. I was thinking that maybe a complete shutdown might fix this issue; so I will try that now and see if a full system reboot will jog the MacBook into connecting to the web, rather than stalling on the WiFi network and going no further.

Wifi issues after upgrading from Maverick to Yosemite. No solutions have worked.

I upgraded to Yosemite 10.10.1 from Mavericks. Having wifi issue where I can't connect to my home network. It connects for 5 seconds than I get "no IP address", and then the connection drops. A free local wifi connection does work. Any ideas until this issue is fixed by Apple? My home router worked fine in Maverick. I tried all the online suggestions but nothing has worked. Have not downgraded yet to Maverick but thinking about it.

MBP WiFi issue after updating to 10.8.5

I have a Macbook Pro late 2011 and used OS X 10.8.4. Last week installed Windows 7 with latest BootCamp. everythings was fine! Then I updated my Mac to newer version (10.8.5).
Now WiFi just works on Windows and Mac does not find any WiFi networks.
My WiFi security is WPA2.
Any one know how do I solve this issue?
Regards,

Back up all data, then reinstall the OS. You don't need to erase the startup volume, and you won't need your backup unless something goes wrong. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
If you installed the Java runtime distributed by Apple and still need it, you'll have to reinstall it.

Ios 8.x wifi issue after update

I have been having intermittent wifi connectivity issues with my apple devices since upgrading to ios 8.x. I've subsequently updated to most recent version 8.0.2 but alas still having the issues of intermittent wifi connectivity issues (wifi works then drops without reason).
The baseline critical information is:
-Cable modem with direct internet connectivity of 20Mbps down and 2Mbps up.
-Home netgear WNDR3700v3 running latest version of firmware V1.0.0.38_1.0.31.
-Apple 5s, 5c, 5 and iPad min, iPad 2 - iphones running latest issue of IOS but ipads intentionally left back to prior versions for purpose of testing.
-Forced DNS servers to google servers 8.8.8.8 and 8.8.4.4
-Security perimeter policies in place prevent external unwarranted proxy attacks, pin hole attacks, etc. No outbound (internal to external) flows are restricted and only established flows (external to internal) are permitted.
Problem statement:
-Wifi will drop on all iphones using current version of ios causing devices to fall back to LTE or 3g.
-Reboot of netgear required to reset wireless settings for internal device usage.
-Cable modem never loses connection to internet and plugging direct into cable modem shows continued network connectivity.
-These issues never were experienced prior to updating to IOS 8.x
Question:
It would appear there is a wifi ios issue. Does anyone have any suggestions ? There are no firmware updates available for netgear given its age (2 years old).
I would prefer to not downgrade ios devices if applicable.

Worth taking a look here:
Why does iOS 8.0.2 not resolve the issue of WiFi connectivity with iOS 8 and the new iPhone 6?

Wifi issues after update to ios4

Hi all,
Since updating to os4, I've been having problems with the wifi on my iphone.
If will connect to my home network fine, but it refuses to use the wifi connection. Checking everything in settings, it all seems fine, it says connected with good strength etc.
But it just doesnt use wifi.
Oddly, the only time the wifi symbol comes up, is in call, which im finding a bit odd. But as soon as I end the call, the wifi symbol disapears and goes back to gprs.
I've rebooted the phone several times, got it to forget wireless networks and set it all up again, reset the network setting, and recently restored and update to os 4.0.2 with no luck.
Anyone got any ideas?

Any problems connecting to any other wi-fi network?
If the same with any other wi-fi network and no change after resetting network settings on your iPhone and after restoring your iPhone with iTunes as a new iPhone or not from your iPhone's backup, more than likely your iPhone has a hardware problem.
You can contact AppleCare or make an appointment at an Apple store if there is one nearby.

Safari hangs after Updating to Mavericks.

Whenever I try to SWIPE(back and forward) between pages in safari, all the trackpad gestures stop working. I cannot even scroll up and down using trackpad. Tried the same in Chrome as well. Witnessed the same issue. But, in Chrome, I can go back to the previous page by clicking on the BACK button. While in Safari, clicking on the back button does not help. I can open and close tabs. but cannot use the trackpad gestures for anything in safari. Kindly help. I have noticed this only after updating to Mavericks. Beforre mavericks, everything was fine.
Details:
OS X 10.9
Safari 7.0 (9537.71)
Chrome Version 30.0.1599.101

This is a common situation. Many third-party internet apps/plugins/extensions claim to be compatible with Macs.
And many are not. It's important to remember to check for any updates to this kinds or things prior to upgrade.
At any rate, very happy you've got your problem resolved.

After updating to Maverick, I need to install iMovie, iPhoto, but have read it has a lot of problems. Is there a fix?

After updating to Maverick, I have heard there are issues with Imovie 11. I want to know if I should buy it?

Thank you so very much for your reply and help!
I went back to the store where I purchased the Mac and I tell you that was an "experience"!. When I explained the overheating problem they informed me that they could send the Mac for service, they said "after all you do have a warrantee and Apple care".
I live in Sweden, but I´m American and as you mention I was expecting that they would immediately offer a new computer, but instead they want to send my 2 day old computer for service?? Not happy!!
Then when I mention that I could not see my external hard drive via Airport Extreme, the guy said that some HD are not able to be read by the Airport Extreme. That was kind of strange since I been using it to back up the G4 via firewire and never had a problem.
As it did not work with my HD as they had promised, I decided to return the Airport Extreme and buy a Time Machine. Then the salesmen informed me that he would buy the Airport Extreme back for a discount. BUY IT BACK and for a discount?? I had it for 2 days!! Never have heard such a thing in my life!
What was suppose to be a dream come true, is turning into a nightmare, I hate the store would love to just give them back the Mac and just order online from Apple. However I´m afraid they will want to buy it back for a "discount" I just spent 4000 dollars in that store, I get no help and instead they want to make more money out of me without a purchase. Sorry, just so upset!
I managed to fix the trash problem, just took "empty secure" away, according to what I have read, sometimes the fans take a while to "kick in" so I´m waiting for them to "kick in" and yes I will reinstall the system completely and hope that will fix the rest.
Thanks again for the help!

After updating to Mavericks and trying to updates for my apps I get : This update is not available for this Apple ID either because it was bought by a different user or the item was refunded or cancelled.

After updating to Mavericks and trying to updates for my apps I get : This update is not available for this Apple ID either because it was bought by a different user or the item was refunded or cancelled. My apple id has always been .mac but after the update I used .me. Are these not synonymous?

Hi everyone yesterday I was experiencing the same problem I am glad to share its fixed now for me
"This issue is only related to our Apple ID and to to those specific apps which we already have on phone or had installed on phone before except for those apps which we already have in purchase history AppStore>Updates>Purchase(on iPhone) History(having cloud icon next to them) it's something related to our purchase data
*ITS NOT RELATED TO PHONE OR MAC!
*RESETTING OR UPDATING THE DEVICE WONT MAKE A DIFFERENCE!
(As in my case it was on iPhone 4 7.1.1 iPhone 5s 7.0.3 and iTunes of course )
Here is how I got it fixed
I contacted apple support via chat method and I asked about a solution giving my info.she told me that she submitted my application and in order to resolve this I should not be using my AppStore ID for any purchase for at least 30mins as doing so may not resolve the issue so I checked it after couple hours and it's fixed
(As I read in some other discussions that some people asked for solution from apple support and they told them to reset the device or so.. You may need to make your statement clear that it's appearing both on iTunes and iPhone )

MBP 2008 late crashes too often after update to Mavericks

My Macbook Pro 2008 late(First generation of Unibody) works perfect on OS X 10.8.x, but after update to Mavericks yesterday, it crashes too often, about 1 hour 1 time.
It seems com.apple.driver.AppleIntelCPUPowerManagement caused the issue, but I have no idea how solve it.
I checked the kernel extensions, found there are some from VirtualBox, so update it to latest 4.3.0 version, it have initial Mavericks support, but crashes still.
