Problems after updating from Mavericks to Yosemite.

Hello everyone.I have noticed some battery problems after updating from Mavericks to Yosemite like no charging at all (but the orange led was on )and not able to fully charged.I solve them with SMC reset and PRAM reset.Furthermore, battery discharges faster than before and its really annoying.Now I have notice that the upper right corner of my mac is getting hot.I'll appreciate any help

Try these in order testing your system after each to see if it's back to normal:
1. a. Resetting your Mac's PRAM and NVRAM
    b. Intel-based Macs: Resetting the System Management Controller (SMC)
2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the Utilities 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.
3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
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 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.
4. Reinstall Yosemite: Reboot from the Recovery HD. Select Reinstall OS X from the Utilities menu, and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
            because it is three times faster than wireless.
5. Reinstall Yosemite from Scratch:
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.

            because it is three times faster than wireless.

Officejet Pro K5400 printing problems after update to Mavericks OSX 10.9

Hi,
I have printing problems with my Officejet Pro K5400 after update to Mavericks OSX 10.9.
Now after printing 1 page the printer prints an extra page with '2345X' sentence on it. As this problem started right after updating, I suppose there is a problem with an update.

This patch did solve our problem with the K5400 feeding a "blank sheet".
Thank you.

Performance problems after Update from 7.6.00.37 to 7.6.03.15

Hi,
after the Update from 7.6.00.37 to 7.6.03.15 in our live system we noticed a lot of performance problems. We have tested the new version before on our test system, but there don't noticed effects like this.
We have 2 identical systems (Opteron 64 bit, openSuse 10.2) with log shipping between them. We updated first the standby system, switched from online to standby (with copy of cold log) and started the new server as online system. After that we run a complete backup (runtime: 1 hour) for starting a new backup history and for activating autolog. Then
With the update we changed USE_OPEN_DIRECT to YES, but the performance of the system was very slow afterwards. After the backup it remains at a high load average (> 10, previous system had about 2-4), with nearly 100% of CPU usage for the db kernel process.
Next day we switched USE_OPEN_DIRECT back to NO. The system first runs better, but periodically rises up to a load average of 6 and slow down the performance of various applications (somebody says about 10 times slower). Here we also noticed a high usage (now 200-300%) of the db kernel process.
Our questions are:
1. Has something basically changed from 7.6.00.37 to 7.6.03.15, so that our various applications (JDBC, ODBC and Perl/SQLDBC partially on old linux systems with drivers from 7.5.00.23) don't reach same performance as before?
2. Are there any other (new) parameters, which can help? Maybe reducing MAXCPU from 4 to 3 for reserving capacities for the system (there is only one maxdb instance running)?
3. Is the a possibility to switch back to 7.6.00.37 (only for worst case)?
I have made some first steps with x_cons, but don't see any anomalies on the first look.
Regards,
Thomas

Hmm... that is really odd. When using USE_OPEN_DIRECT there is actually less work to do for he operating system.

Well of course there are bugs that have been found inbetween the release of both versions, but I am not aware of something like the performance killer.
We will have to check this in detail here.

Well - then I guess 'looking at the system' won't bring you far...

Great - let's see the warnings you get.
Let us also see the DB Parameters you set.

With the old version we had no problems with missing indexes or the general performance. Unfortunatly it is very difficult to extract some sql statements out of the JBoss applications. But even simple queries (without any join) runs slower, when the load average rises over 4-5.
Hmm... the question here is still, if the execution plans are good enough to meet your expectations.
E.g. for tables that you access via the primary key it actually doesn't matter how many rows a table has (not for MaxDB at least).

Sounds like the I/O is your most suspect aspect for overall system performance...

Ok - so this is next to no testing at all when it comes to performance.
> An UPDATE STATISTICS over all db users seems to change nothing. At the moment the system remains markedly slow and we are searching for reasons and solutions. Another attempt will be the change of MAXCPU from 4 to 3.
Why do you want to do that? Have you observed any threads that don't get a CPU because all 4 cores are used by the MaxDB kernel?

Serious performance problems after updating from 10.5.6 to 10.5.7

I've got a Macbook Pro C2D 15" (late 2006). After updating the system from 10.5.6 to 10.5.7 and quicktime to 7.6.2, I experience serious performance problems which I have never seen before:
-From time to time, kernel_task has peaks in activity monitor (consumes a lot of CPU). In that moment, the mouse hangs for a short moment and audio playback is distorted/has drop outs.
-Recording audio consumes a lot of CPU (independent of the audio application).
-Video playback consumes a lot of CPU, regardless if I use VLC or the quicktime player.
Any idea what could be done? Thanks in advance.

After a few days of using CoolBook I report that my 1st generation MacBook Air is now reliable and never overheating, regardless of environment conditions.
I must point out that I do believe that it really is something new in 10.5.7 that is causing this problem as my environmental conditions have not changed and even Summer in Dublin still sees temperatures no more than 72F/22C. I am now in Madrid, where the environment is quite different, and I am still having no problem with kernel_task spinning.
I plan on reporting my problem to Apple anyway and being aggressive about the issue as MacLovinRanga did in this thread (http://discussions.apple.com/thread.jspa?messageID=9647353#9647353). Perhaps many/all of those of us having this problem will obtain new MacBook Airs.

Problems after updating to Maverick

Since updating to Maverick 10.9.1 this week I'm unable to save a file when working in PS CC or even change the name of folder in Bridge. Anyone else having the same problem? I also noticed that sometimes when I try to Save As, PS displays this as the destination folder (/Users/.../20140221/ohjgz86XT4WFz3DpQRhs+Q/IMG_022.jpg) No idea what that is directing me to. The only thing I've found is that sometimes I can save a file to my Desktop then move it into PS. It still doesn't solve the problem with managing folders in Bridge though. Any ideas or similar experiences?

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 the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login 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.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

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.

Thinkpad G40 keyboard problems after updating from W98 to W7

Hi community users.
I'm new here with a, for me, typical problem.
I’m having a problem with my Laptop keyboard IBM ThinkPad G40, type: 23884SG, Windows 7.
Since I updated from Windows 98 to Windows 7 the keyboard definition is wrong. I’m not able to find the right configuration of it on base of the standard list of country and language definitions in W7.
Who can help me with this.
I already installed some drivers from the Lenova site but nothing seems to help.
So the problem is that I can’t find the right service from the country and language menu to the keyboard in W7.
All suggestions are very welcome.
Thanks in advance,
Dirk

Hi Vince,
Thanks for your response to my problem.
Problem isn't the choice of the specific language. The problem after the update is that I'm not able to choose the right combination of language and the type of keyboard selection in Windows 7. The selection list is long: from South-Africa to Sweden.
Although most of the characters on the keys on the lower part of the keyboard correspond with the ones on the screen but especially the keys on the upper part don't.
So I'm searching to a correct selection of the combination language and specific type of keyboard. Or there must be some driver witch can be download.
Looking forward to the feedback.
Kind regards,
Dirk

Problems after updating from 2.0.5 to 2.08

Hi Community,
I updated my Developer Studio from 2.05 to 2.08 but I got some problems now. The Behaviour of my WD Application written on 2.0.5 changed.
I got a View which contains a tree control. For this tree control I implemented the method onActionSelect.
public void onActionSelect(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent, com.sap.tut.wd.tree.wdp.IPrivateTreeView.ITreeNodeElement selectedElement )
//@@begin onActionSelect(ServerEvent)
if( selectedElement == null)
wdContext.currentContextElement().setLabelname("Element = null");
//wdThis.wdFirePlugToDispatcherView(selectedElement);
//@@end
If I check the parameter selectedElement now for null, I get true. That means this structure isn't filled out automatically anymore.
Do s.b. know something about API changes or how to fix this problem? Regards and thank's a lot, Robert.

Hi Robert,
Errors occur if there are inconsistencies between the Engine (e.g. Support Package 5) and the Developer Studio (e.g. Support Package 6).
Other "Class not found exceptions" or "No such method exceptions" may appear in the case of other Support Packages. Unfortunately, this results in a termination of the application at runtime.
You must ensure that the local version of the Netweaver Developer Studio has the same version level as the CBS
configuration.
In particular, the IDE plug-ins must not have a higher version than the generators of the CBS. Possible is a lower version of the IDE.
Hope that helps.
Best regards,
Karin

Can't enable Device Manager after upgrading from Mavericks to Yosemite

We have an Apple Mac Mini Server that was purchased and configured with OS X 10.9. This was configured as part of a golden triangle, managing 10 Apple Mac Minis in a Microsoft Active Directory environment. We had enabled Profile Manager and configured Device Manager.
We recently upgraded to Yosemite, and upgraded Server.app to 4.0.3. Device Manager is now disabled, can when we try and configure it, we get 'An error with code -1 occurred'. We have tried resetting the Device Manager configuration, but this hasn't fixed the issue.
Any suggestions?

Mobile App problem after update from Flex SDK 4.5 to 4.5.1

I have a mobile app that built in SDK 4.5 and running ok until update the SDK to 4.5.1 and then the app only loads the splash page and not even to to the firstview. The screen just stop at the splash page and no reaction, no debug window popup (test on the computer). If I change back to SDK 4.5, everything goes normal. Does anyone has the same issue? Please help.
I am in Win 7, Flash Builder SDK 4.5.1 plugin in Eclipse Helios.
Thanks.
Tony

Thanks for your respond. I wish I could show you my app; however this project is pretty big. Besides the UI part that was built for mobile, there are also part of the codes are including (referenceing) the old desktop project that still are complie in SDK 4.1. Mainly for the referencing codes to the old project are Caingorm's commands and service locators part, for getting the service call. Everything is fine and running on computer and mobile devices when using SDK 4.5.
I can try to build something to see if it will show the same situation. Thanks.

I updated from Mavericks to OS X Yosemite without backup

Hello,
First , i have a
iMac (24-inch Mid 2007)
Processor 2.4 GHz intel Core 2 Duo
Memory 4GB 667 MHz DDR2 SDRAM
Storage Capacity 32.23 GB free of 319.21 GB
I haven't try any temporary fixes other than restart and download again.
Problem: I update from Mavericks to SO Yosemite without back-up. Everything is great but now iPhoto will not open even after I downloaded the iPhoto Library Upgraded available from Apple.
Question: Anyone else having the same problem and if so how do i fix this?
Problem: I have an external hard drive of 500 GB for my Time Machine but afraid to use it because it might delete my previous work and photo.
Question: How can i recover my photos?
Thanks,
Eric

I have a 2008 iMac and a 2008 MacBook Pro and had the same issue with iPhoto after installing Yosemite.
I downloaded the latest iPhoto and then got the message to run the iPhoto Library Upgrader which I did.After that I opened the new iPhoto and it upgraded all my pics.
Are you sure you have the latest iPhoto - available free from the App Store?

Fire fox 14 is crashing every 15 minutes. Usining win7 .This is after updating from FF13. require a solution.

FF14 is crashing randomly after every 15 minutes. Is this problem a general problem after updating from FF13. All plugins are up to date. No virus on system. Does any one have any solutions?
Thanks

More information, from the crash report for the first Crash ID listed in "More system details":
https://crash-stats.mozilla.com/report/index/63e76a0f-b807-4eab-a83c-4d14c2120719 Firefox 14.0.1 Crash Report [@ StrChrIA ]
.....the crash report links to a related bug,
[https://bugzilla.mozilla.org/show_bug.cgi?id=530074
Bug 530074 - Crash [@ StrChrIA ] from winsock and shlwapi.dll (LSP, evil *x86.dll module, or BitDefender)]
So, your crash seems to be related to Bit Defender antivirus software or one if its components (BdProvider.dll). I did a google search and according to [http://systemexplorer.net/filereviews.php?fid=11324853 this page], the file BdProvider.dll is the Bitdefender parental provider plugin.
If Firefox no longer crashes when you [[Safe Mode|restart with add-ons disabled]], look in the Firefox Add-ons Extensions list for any BitDefender add-on and disable it (see [[Disable or remove add-ons]] for details), then restart Firefox to see if the crashes stop.
You could also contact BitDefender support or ask for help on the [http://forum.bitdefender.com BitDefender forums].

From Mavericks to Yosemite, current Aperture unavailable, "Purchased"not working

Updated from Mavericks to Yosemite, which made my current Aperture 3.5 unavailable, I went to the App Store, went to "Purchased" to update to 3.6 found Aperture and clicked update. I get a small spinning thing on the upper left, but there is no activity, I get a little spinner but it stops and looking at what is being downloaded I see very little activity from the app store.

The solution, for me, is here.
